Abstract:
ABSTRACTImmunoreactive components ofOpisthorchis viverriniandClonorchis sinensiswere analysed by enzyme-linked immunosorbent assay (ELISA), radioimmunoprecipitation and immunoblotting. Somatic extracts from these two liver flukes as well as from other related parasites, together with the metabolic products, were tested for their reactivities with sera from patients with opisthorchiasis and clonorchiasis. A significant cross-reactivity in the ELISA was noted betweenOpisthorchisandClonorchis. Immunoblotting and radioimmunoprecipitation analyses showed that the 89-kD protein which was previously shown to be a predominant metabolic product ofO. viverrinireacted with sera from both groups of patients. However, an antigen with a molecular weight of 16 kD, apparently a predominant somatic component, appeared to be specific forO. viverrini.

Abstract:
Polyclonal antibodies to native RNA polymerase II of Achlya ambisexualis and Agaricus bisporus were produced in rabbits and in mice. Monoclonal antibodies were produced against the α-amanitin resistant RNA polymerase II of the mushroom A. bisporus. These antibodies were used in comparative cross-reactivity studies with five purified RNA polymerases II (A. bisporus, A. ambisexualis, Saccharomyces cerevisiae, wheat germ, and calf thymus). A method for quantitatively comparing cross-reactivity was developed utilizing an enzyme-linked immunosorbant assay (ELISA). ELIS A comparisons indicated that the two filamentous fungi cross-reacted effectively with one another and depending upon the preparation reacted less effectively with yeast and wheat germ RNA polymerases II. Cross-reactivity measurements were also made by immunoblotting sodium dodecyl sulfate – polyacrylamide separated RNA polymerases II. The mouse anti-A. bisporus RNA polymerase II immunoglobulin G (IgG) and the monoclonal antibody preparations did not react with high molecular subunits of A. bisporus RNA polymerase II. The sera did, however, cross-react with high molecular weight subunits of A. ambisexualis. Similarily, rabbit anti-A. ambisexualis RNA polymerase II IgG reacted only with low molecular weight subunits of A. bisporus RNA polymerase II, but reacted with high molecular weight subunits of A. ambisexualis and wheat germ. Our results indicate differences in the cross-reactivity of native and denatured RNA polymerases II and suggest differences in the tertiary and quaternary organization of the enzymes examined.

Abstract:
Immunological and microwear analysis was performed on 100 chipped-stone artifacts from four prehistoric sites located in the Virginia Piedmont. A total of 20 artifacts returned positive results for immunological analysis and 16 artifacts returned microwear results. The findings indicate the negative effects of postdepositional processes and the potential utility of the techniques for deciphering prehistoric activities, otherwise unavailable by conventional studies in piedmont contexts. The study further illustrates the value and problems associated with immunological and microwear analyses on chipped-stone assemblages.

Abstract:
We have used cultured sympathetic neurons to identify microtubule proteins (tubulin and microtubule-associated proteins [MAPs]) and neurofilament (NF) proteins in pure preparations of axons and also to examine the distribution of these proteins between axons and cell bodies + dendrites. Pieces of sympathetic ganglia containing thousands of neurons were plated onto culture dishes and allowed to extend neurites. Dendrites remained confined to the ganglionic explant or cell body mass (CBM), while axons extended away from the CBM for several millimeters. Axons were separated from cell bodies and dendrites by dissecting the CBM away from cultures, and the resulting axonal and CBM preparations were analyzed using biochemical, immunoblotting, and immunoprecipitation methods. Cultures were used after 17 d in vitro, when 40-60% of total protein was in the axons. The 68,000-mol-wt NF subunit is present in both axons and CBM in roughly equal amounts. The 145,000- and 200,000-mol-wt NF subunits each consist of several variants which differ in phosphorylation state; poorly and nonphosphorylated species are present only in the CBM, whereas more heavily phosphorylated forms are present in axons and, to a lesser extent, the CBM. One 145,000-mol-wt NF variant was axon specific. Tubulin is roughly equally distributed between CBM and axon-like neurites of explant cultures. MAP-1a, MAP-1b, MAP-3, and the 60,000-mol-wt MAP are also present in the CBM and axon-like neurites and show distribution patterns similar to that of tubulin. In contrast, MAP-2 was detected only in the CBM, while tau and the 210,000-mol-wt MAP were greatly enriched in axons compared to the CBM. In immunostaining analyses, MAP-2 localized to cell bodies and dendrite-like neurites, but not to axon-like neurites, whereas antibodies to tubulin and MAP-1b localized to all regions of the neurons. The regional differences in composition of the neuronal cytoskeleton presumably generate corresponding differences in its structure, which may, in turn, contribute to the morphological differences between axons and dendrites.

Abstract:
Brucella abortus is a facultative, intracellular zoonotic pathogen, which can cause undulant fever in humans and abortion in cattle. Despite all of the progress in brucellosis research, there are still many unanswered questions regarding the molecular mechanisms involved in the pathogenesis of Brucella infections. To better understand the Brucella antigens involved in virulence and/or immunity, genetic and immunologic characterization of a 16 kDa protein of B. abortus was performed. Using PCR methods, the gene encoding the 16 kDa protein was cloned and sequenced. PCR and Southern blot analysis revealed that the gene is conserved among the 6 nomen species of Brucella. Overexpression of this protein in B. abortus vaccine strain RB51 was achieved using Brucella groE and sodC promoters as well as its own promoter. Protection and clearance studies were performed in mice to determine the role of this protein in Brucella immunity and pathogenesis. Inoculation with either strain RB51 overexpressing the 16 kDa protein or a DNA vaccine encoding the 16 kDa protein gene failed to provide significant protection. No difference was noted between the splenic clearance of B. abortus strain 2308 and its recombinant overexpressing the 16 kDa protein. A mutant of strain 2308 (2308D16) was created by disrupting the 16 kDa proteinâ s gene with a chloramphenicol resistance cassette. Western blot analysis indicated that the O antigen profile of strain 2308D16 differed from that of strain 2308. Mice cleared strain 2308D16 faster than strain 2308 indicating the potential attenuation of the disruption mutant. Purified 16 kDa protein was obtained by overexpressing it in E. coli via the pRSET expression system. Western blotting results initially identified this protein as an immunoglobulin-binding protein. Hemagglutination assay revealed that the 16 kDa protein exhibits lectin-like properties. Preliminary studies using hemagglutination inhibition identified mannose as a possible sugar to which the 16 kDa protein can interact. The lectin-like properties exhibited by the 16 kDa protein appears to influence smooth lipopolysaccharide production, and thereby may be involved in virulence.

Pericardial tuberculosis (TB) offers a relevant human model to study TB at the site of disease and to determine the effect of HIV-1 infection. 96 Patients with pericardial TB were recruited into this study, 68 of whom were HIV-1 infected. Where clinically indicated, pericardiocentesis was performed to drain pericardial fluid and blood was drawn. The data derived from the study provide novel insight into the immune response in the pericardium to TB infection. Furthermore, HIV-1 infection caused a dysregulation of the immune response.

Abstract:
The aim of this project was to assess the expression, purification and immunogenicity in mice of two important HIV antigens, the core protein p24 and the regulatory protein Nef, produced in transplastomic Nicotiana tabacum plants. A comparison of p24-expressing tobacco Petite Havana transplastomic plants, containing gene constructs with different 5’ untranslated regions (UTRs), demonstrated the importance of regulatory and stabilizing elements. Plants containing a p24 construct with a bacteriophage T7 gene 10 (T7g10) 5’ UTR and generating a protein with 5 extra amino acids at the N-terminus, accumulated almost twice as much protein as plants containing other constructs. Analysis of p24 accumulation in leaves of the high biomass tobacco variety Maryland Mammoth revealed a dramatic difference between a transplastomic line containing a codon-optimized construct encoding five extra N-terminal amino acids, which accumulated p24 in all leaves of the plant, and a transplastomic line containing a native p24 construct which accumulated p24 only in young leaves. To assess the subcutaneous and nasal immunogenicity of plant-derived p24, the protein was purified to ~95% homogeneity from Maryland Mammoth transplastomic plants. After immunization of experimental mice, ELISAs for p24-specific IgG and T-cell proliferation assays showed that chloroplast p24 could elicit a strong humoral response following subcutaneous administration and a cellular response following intranasal administration. Oral administration of partially purified tobacco p24-Nef as a booster, after subcutaneous priming with either p24 or Nef, elicited strong humoral and cellular responses, with both IgG1 and IgG2 subtypes found in sera. In addition, tobacco BiP was found to be as good an adjuvant as Vibrio cholerae toxin B and Mycobacterium tuberculosis Hsp70 for enhancing the immune response to p24.

Full text
Abstract:
Cathepsin D is a lysosomal acid proteinase that exists as different isoforms. This enzyme is found in most cell types, and macrophages have particularly high levels of this enzyme. Cathepsin D has been implicated in some disease related inflammatory processes that have also been associated with increased macrophage infiltration. The existance of isoforms of cathepsin D suggested the possibility that individual forms of this enzyme may have immunologically unique characteristics. Monoclonal antibodies to cathepsin D could aid in the study of the immunological characteristics of individual isoforms of this enzyme as well as provide a means by which to screen a variety of sample types for cathepsin D levels. In this study we generated a panel of monoclonal anti-cathepsin D antibodies and used these to screen isoelectrically separated cathepsin D samples for unique immunoreactivity patterns. We also used these antibodies to measure changes in the levels of intra- and extracellular cathepsin D that accompany monocyte to macrophage differentiation, and changes that occur in response to the treatment of melanoma cells with tumor necrosis factor (TNF) and interferon. We found that there are unique immunological characteristics associated with individual isoforms of human liver cathepsin D as well as cathepsin D from different cell types. We also observed increases in levels of this enzyme as monocytic cells differentiate to macrophage-like cells. This indicates that cathepsin may be involved in some of the proteolytic processes mediated by macrophages. Different inducers of differentiation resulted in different cathepsin 1D immunoreactivity patterns, suggesting that there may be isoform specificity dependent on the inducer. Cathepsin D levels also increase in neoplastic cells treated with TNF and/or interferon indicating that cathepsin D may play some role in the mechanism of action of the tumor inhibitory effects of these agents. The use of monoclonal antibodies provides assays for cathepsin D which can be used with a variety of sample types and further provides enhanced specificity and sensitivity relative to other assay systems used in the past.

Abstract:
In Israel and in the U.S., Streptococcus iniae is responsible for considerable losses in various fish species. Poor understanding of its virulence factors and limited know-how-to of vaccine formulation and administration are the main reasons for the limited efficacy of vaccines. Our strategy was that in order to Improve control measures, both aspects should be equally addressed. Our proposal included the following objectives: (i) construction of host-pathogen interaction models; (ii) characterization of virulence factors and immunodominant antigens, with assessment of their relative importance in terms of protection and (iii) genetic identification of virulence factors and genes, with evaluation of the protective effect of recombinant proteins. We have shown that two different serotypes are involved. Their capsular polysaccharides (CPS) were characterized, and proved to play an important role in immune evasion and in other consequences of the infection. This is an innovative finding in fish bacteriology and resembles what, in other fields, has become apparent in the recent years: S. iniae alters surface antigens. By so doing, the pathogen escapes immune destruction. Immunological assays (agar-gel immunodiffusion and antibody titers) confirmed that only limited cross recognition between the two types occurs and that capsular polysaccharides are immunodominant. Vaccination with purified CPS (as an acellular vaccine) results in protection. In vitro and ex-vivo models have allowed us to unravel additional insights of the host-pathogen interactions. S. iniae 173 (type II) produced DNA fragmentation of TMB-8 cells characteristic of cellular necrosis; the same isolate also prevented the development of apoptosis in NCC. This was determined by finding reduced expression of phosphotidylserine (PS) on the outer membrane leaflet of NCC. NCC treated with this isolate had very high levels of cellular necrosis compared to all other isolates. This cellular pathology was confirmed by observing reduced DNA laddering in these same treated cells. Transmission EM also showed characteristic necrotic cellular changes in treated cells. To determine if the (in vitro) PCD/apoptosis protective effects of #173 correlated with any in vivo activity, tilapia were injected IV with #173 and #164 (an Israeli type I strain). Following injection, purified NCC were tested (in vitro) for cytotoxicity against HL-60 target cells. Four significant observations were made : (i) fish injected with #173 had 100-400% increased cytotoxicity compared to #164 (ii) in vivo activation occurred within 5 minutes of injection; (iii) activation occurred only within the peripheral blood compartment; and (iv) the isolate that protected NCC from apoptosis in vitro caused in vivo activation of cytotoxicity. The levels of in vivo cytotoxicity responses are associated with certain pathogens (pathogen associated molecular patterns/PAMP) and with the tissue of origin of NCC. NCC from different tissue (i.e. PBL, anterior kidney, spleen) exist in different states of differentiation. Random amplified polymorphic DNA (RAPD) analysis revealed the "adaptation" of the bacterium to the vaccinated environment, suggesting a "Darwinian-like" evolution of any bacterium. Due to the selective pressure which has occurred in the vaccinated environment, type II strains, able to evade the protective response elicited by the vaccine, have evolved from type I strains. The increased virulence through the appropriation of a novel antigenic composition conforms with pathogenic mechanisms described for other streptococci. Vaccine efficacy was improved: water-in-oil formulations were found effective in inducing protection that lasted for a period of (at least) 6 months. Protection was evaluated by functional tests - the protective effect, and immunological parameters - elicitation of T- and B-cells proliferation. Vaccinated fish were found to be resistant to the disease for (at least) six months; protection was accompanied by activation of the cellular and the humoral branches.

Abstract:
The goal of this research was to provide a better understanding of the interface between root-knot nematodes, Meloidogyne spp., and their host in order to develop rational targets for plantibodies and other novel methods of nematode control directed against the nematode surface coat (SC). Specific objectives were: 1. To produce additional monoclonal SC antibodies for use in Objectives 2, 3, and 4 and as candidates for development of plantibodies. 2. To determine the production and distribution of SC proteins during the infection process. 3. To use biochemical and immunological methods to perturbate the root-knot nematode SC in order to identify SC components that will serve as targets for rationally designed plantibodies. 4. To develop SC-mutant nematodes as additional tools for defining the role of the SC during infection. The external cuticular layer of nematodes is the epicuticle. In many nematodes, it is covered by a fuzzy material termed "surface coat" (SC). Since the SC is the outermost layer, it may playa role in the interaction between the nematode and its surroundings during all life stages in soil and during pathogenesis. The SC is composed mainly of proteins, carbohydrates (which can be part of glycoproteins), and lipids. SC proteins and glycoproteins have been labeled and extracted from preparasitic second-stage juveniles and adult females of Meloidogyne and specific antibodies have been raised against surface antigens. Antibodies can be used to gain more information about surface function and to isolate genes encoding for surface antigens. Characterization of surface antigens and their roles in different life-stages may be an important step towards the development of alternative control. Nevertheless, the role of the plant- parasitic nematode's surface in plant-nematode interaction is still not understood. Carbohydrates or carbohydrate-recognition domains (CROs) on the nematode surface may interact with CROs or carbohydrate molecules, on root surfaces or exudates, or be active after the nematode has penetrated into the root. Surface antigens undoubtedly play an important role in interactions with microorganisms that adhere to the nematodes. Polyclonal (PC) and monoclonal (MC) antibodies raised against Meloidogyne javanica, M. incognita and other plant-parasitic nematodes, were used to characterize the surface coat and secreted-excreted products of M. javanica and M. incognita. Some of the MC and PC antibodies raised against M. incognita showed cross-reactivity with the surface coat of M. javanica. Further characterization, in planta, of the epitopes recognized by the antibodies, showed that they were present in the parasitic juvenile stages and that the surface coat is shed during root penetration by the nematode and its migration between root cells. At the molecular level, we have followed two lines of experimentation. The first has been to identify genes encoding surface coat (SC) molecules, and we have isolated and characterized a small family of mucin genes from M. incognita. Our second approach has been to study host genes that respond to the nematode, and in particular, to the SC. Our previous work has identified a large suite of genes expressed in Lycopersicon esculentum giant cells, including the partial cDNA clone DB#131, which encodes a serine/threonine protein kinase. Isolation and predicted translation of the mature cDNA revealed a frame shift mutation in the translated region of nematode sensitive plants. By using primers homologous to conserved region of DB#131 we have identified the orthologues from three (nematode-resistant) Lycopersicon peruvianum strains and found that these plants lacked the mutation.

Identification of Avian Infectious Brochitis Virus Variant Serotypes and Subtypes by PCR Product Cycle Sequencing for the Rational Selection of Effective Vaccines. United States Department of Agriculture, December 2003. http://dx.doi.org/10.32747/2003.7586470.bard.

Abstract:
Objectives 1. Determine the serotypic identities of 40 recent IBV isolates from commercial chickens raised in the USA and Israel. 2. Sequence all IBV field isolates using PCR product cycle sequencing and analyze their S 1 sequence to detennine their homology to other strains in the Genbank and EMBL databases. 3. Select vaccinal strains with the highest S 1 sequence homology to the field isolates and perform challenge of immunity studies in chickens in laboratory trials to detennine level of protection afforded by the vaccines. Background Infectious bronchitis (IB) is a common, economically important disease of the chicken. IB occurs as a respiratory form, associated with airsacculitis, condemnation, and mortality of meat-type broilers, a reproductive form responsible for egg production losses in layers and breeders, and a renal form causing high mortality in broilers and pullets. The causative agent is avian coronavirus infectious bronchitis virus (IBV). Replication of the virus' RNA genome is error-prone and mutations commonly result. A major target for mutation is the gene encoding the spike (S) envelope protein used by the virus to attach and infect the host cell. Mutations in the S gene result in antigenic changes that can lead to the emergence of variant serotypes. The S gene is able to tolerate numerous mutations without compromising the virus' ability to replicate and cause disease. An end result of the virus' "flexibility" is that many strains of IBV are capable of existing in nature. Once formed, new mutant strains, often referred to as variants, are soon subjected to immunological selection so that only the most antigenically novel variants survive in poultry populations. Many novel antigenic variant serotypes and genotypes have been isolated from commercial poultry flocks. Identification of the field isolates of IBV responsible for outbreaks is critical for selecting the appropriate strain(s) for vaccination. Reverse transcriptase polymerase chain reaction (RT-PCR) of the Sl subunit of the envelope spike glycoprotein gene has been a common method used to identify field strains, replacing other time-consuming or less precise tests. Two PCR approaches have been used for identification, restriction fragment length polymorphism (RFLP) and direct automated cycle sequence analysis of a diagnostically relevant hypervariab1e region were compared in our BARD research. Vaccination for IB, although practiced routinely in commercial flocks, is often not protective. Field isolates responsible for outbreaks may be unrelated to the strain(s) used in the vaccination program. However, vaccines may provide varying degrees of cross- protection vs. unrelated field strains so vaccination studies should be performed. Conclusions RFLP and S1 sequence analysis methods were successfully performed using the field isolates from the USA and Israel. Importantly, the S1 sequence analysis method enabled a direct comparison of the genotypes of the field strains by aligning them to sequences in public databases e.g. GenBank. Novel S1 gene sequences were identified in both USA and Israel IBVs but greater diversity was observed in the field isolates from the USA. One novel genotype, characterized in this project, Israel/720/99, is currently being considered for development as an inactivated vaccine. Vaccination with IBV strains in the US (Massachusetts, Arkansas, Delaware 072) or in Israel (Massachusetts, Holland strain) provided higher degrees of cross-protection vs. homologous than heterologous strain challenge. In many cases however, vaccination with two strains (only studies with US strains) produced reasonable cross-protection against heterologous field isolate challenge. Implications S1 sequence analysis provides numerical similarity values and phylogenetic information that can be useful, although by no means conclusive, in developing vaccine control strategies. Identification of many novel S1 genotypes of IBV in the USA is evidence that commercial flocks will be challenged today and in the future with strains unrelated to vaccines. In Israel, monitoring flocks for novel IBV field isolates should continue given the identification of Israel/720/99, and perhaps others in the future. Strains selected for vaccination of commercial flocks should induce cross- protection against unrelated genotypes. Using diverse genotypes for vaccination may result in immunity against unrelated field strains.

Abstract:
Our long-term goal is to develop an efficient acellular vaccine against paratuberculosis based on protein antigen(s). A prerequisite to achieve this goal is to analyze and characterize Mycobacterium paratuberculosis (Mpt) secreted and cellular proteins eliciting a protective immune response. In the context of this general objective, we proposed to identify, clone, produce, and characterize: the Mpt 85B antigen and other Mpt immunoreactive secreted proteins, the Mpt L7/L12 ribosomal protein and other immunoreactive cellular proteins, Mpt protein determinants involved in invasion of epithelial cells, and Mpt protein antigens specifically expressed in macrophages. Paratuberculosis is still a very serious problem in Israel and in the USA. In the USA, a recent survey evaluated that 21.6% of the dairy herd were infected with Mpt resulting in 200-250 million dollars in annual losses. Very little is known on the virulence factors and on protective antigens of Mpt. At present, the only means of controlling this disease are culling or vaccination. The current vaccines do not allow a clear differentiation between infected and vaccinated animals. Our long-term goal is to develop an efficient acellular paratuberculosis vaccine based on Mpt protein antigen(s) compatible with diagnostic tests. To achieve this goal it is necessary to analyze and characterize secreted and cellular proteins candidate for such a vaccine. Representative Mpt libraries (shuttle plasmid and phage) were constructed and used to study Mpt genes and gene products described below and will be made available to other research groups. In addition, two approaches were performed which did not yield the expected results. Mav or Mpt DNA genes that confer upon Msg or E. coli the ability to invade and/or survive within HEp-2 cells were not identified. Likewise, we were unable to characterize the 34-39 kDa induced secreted proteins induced by stress factors due to technical difficulties inherent to the complexity of the media needed to support substantial M. pt growth. We identified, isolated, sequenced five Mpt proteins and expressed four of them as recombinant proteins that allowed the study of their immunological properties in sensitized mice. The AphC protein, found to be up regulated by low iron environment, and the SOD protein are both involved in protecting mycobacteria against damage and killing by reactive oxygen (Sod) and nitrogen (AhpC) intermediates, the main bactericidal mechanisms of phagocytic cells. SOD and L7/L12 ribosomal proteins are structural proteins constitutively expressed. 85B and CFP20 are both secreted proteins. SOD, L7/L12, 85B and CFP20 were shown to induce a Th1 response in immunized mice whereas AphC was shown by others to have a similar activity. These proteins did not interfere with the DTH reaction of naturally infected cows. Cellular immunity provides protection in mycobacterial infections, therefore molecules inducing cellular immunity and preferentially a Th1 pathway will be the best candidate for the development of an acellular vaccine. The proteins characterized in this grant that induce a cell-mediated immunity and seem compatible with diagnostic tests, are good candidates for the construction of a future acellular vaccine.
