Повний текст джерелаThe Human Immunodeficiency Virus (HIV) is the etiologic agent of Acquired Immunodeficiency Syndrome (AIDS). AIDS is a disease which has a global distribution, and it is estimated that there are currently at least 36.9 million people infected with the virus. During the replication cycle, HIV promotes several changes in the physiology of the host cell to promote their survival and enhance replication. The fast progression of HIV-1 in humans and animal models is closely linked to the function of an accessory protein Nef. Among several actions of Nef, one is the most important is the down-regulation of proteins from the immune response, such as the CD4 receptor. It is known that this action causes CD4 degradation in lysosome, but the molecular mechanisms are still incompletely understood. Nef forms a tripartite complex with the cytosolic tail of the CD4 and adapter protein 2 (AP-2) in clathrin-coated vesicles, inducing CD4 internalization and lysosome degradation. Previous research has demonstrated that CD4 target to lysosomes by Nef involves targeting of this receptor to multivesicular bodies (MVBs) pathway by an atypical mechanism because, although not need charging ubiquitination, depends on the proteins from ESCRTs (Endosomal Sorting Complexes Required for Transport) machinery and the action of Alix, an accessory protein ESCRT machinery. It has been reported that Nef interacts with subunits of AP- 1, AP-2, AP-3 complexes and Nef does not appear to interact with AP-4 and AP-5 subunits. However, the role of Nef interaction with AP-1 or AP-3 in CD4 down-regulation is poorly understood. Furthermore, AP-1, AP-2 and AP-3 are potentially heterogeneous due to the existence of multiple subunits isoforms encoded by different genes. However, there are few studies to demonstrate if the different combinations of APs isoforms are form and if they have distinct functional properties. This study aim to identify and characterize cellular factors involved on CD4 down-modulation induced by Nef from HIV-1. More specifically, this study aimed to characterize the involvement of AP-1 complex in the down-regulation of CD4 by Nef HIV-1 through the functional study of the two isoforms of ?-adaptins, AP-1 subunits. By pull-down technique, we showed that Nef is able to interact with ?2. In addition, our data from immunoblots indicated that ?2- adaptin, not ?1-adaptin, is required in Nef-mediated targeting of CD4 to lysosomes and the ?2 participation in this process is conserved by Nef from different viral strains. Furthermore, by flow cytometry assay, ?2 depletion, but not ?1 depletion, compromises the reduction of surface CD4 levels induced by Nef. Immunofluorescence microscopy analysis also revealed that ?2 depletion impairs the redistribution of CD4 by Nef to juxtanuclear region, resulting in CD4 accumulation in primary endosomes. Knockdown of ?1A, another subunit of AP-1, resulted in decreased cellular levels of ?1 and ?2 and, compromising the efficient CD4 degradation by Nef. Moreover, upon artificially stabilizing ESCRT-I in early endosomes, via overexpression of HRS, internalized CD4 accumulates in enlarged HRS-GFP positive endosomes, where co-localize with ?2. Together, the results indicate that ?2-adaptin is a molecule that is essential for CD4 targeting by Nef to ESCRT/MVB pathway, being an important protein in the endo-lysosomal system. Furthermore, the results indicate that ?-adaptins isoforms not only have different functions, but also seem to compose AP-1 complex with distinct cell functions, and only the AP-1 variant comprising ?2, but not ?1, acts in the CD4 down-regulation induced by Nef. These studies contribute to a better understanding on the molecular mechanisms involved in Nef activities, which may also help to improve the understanding of the HIV pathogenesis and the related syndrome. In addition, this work contributes with the understanding of primordial process regulation on intracellular trafficking of transmembrane proteins.

It’s the first time in Taiwan using EBSD (electron back-scattering diffraction) techniques to analyze two dimensional distributions of residual strain and dislocation density. This thesis has two parts: firstly, using DIC (digital image correlation) and EBSD to measure two dimensional distribution of residual strain; secondarily, combining critical stress analysis and EBSD technique to calculate two dimensional distribution of dislocation density. Single aluminum, single copper and alumni nitride thin film on single silicon substance were chosen as experimental materials and performed using indentation testing. The maximum of residual tensile strain in the vicinity of the indentation tip is 0.02 for AlN/Si. The maximum value of residual strain and total dislocation density for 10g-indented single Al are 0.012 and m-2, respectively. In the case of single Cu using 5g nano-indentation, the maximum residual and total dislocation density are 0.041 and m-2, respectively. The maximum residual and total dislocation density are 0.087 and m-2 for single Cu loaded by 10g nano-indentation, respectively.

Aflatoxins(AF) are toxic and carcinogenic secondary metabolites produced by Aspergillus section Flavi, Aspergillus flavus and A. parasiticus. Particularly aflatoxin B1 is the most potent known hepatocarcinogenic compound. The regular meeting in stores up on the improper grain to accumulate, but causes the humanity or the domestic animal which eats by mistake has in the health the concealed worry. TLC (Thin- Layer Chromatography) analysis was used to detect aflatoxin production of 2 strains of A. flavus, CCRC 30231, CCRC 30290 and 5 strains of A. parasiticus, CCRC 30117, CCRC 30150, CCRC 30160, CCRC 30164 and CCRC 30172. The strains were grown in YES (aflatoxin-inducive) and YEP (non- aflatoxin-inducive) broth. It is indeed that all seven strains were able to produce aflatoxin in YES broth, but differed in aflatoxin types and contents. Furthermore we determined the culture medium content, as well as incubation time, influenced regulatory mechanism of aflatoxin biosynthetic pathway. Fifty genes related to aflatoxin biosynthesis were studied, included thirty-one genes which are involved in aflatoxin B1 biosynthesis: fas1, fas2, pks, pksA, nor1, norA, norB, nor, avnA, adhA, adh1, adh2, avfA, estA1, estA2, vbs, verB, verA, ver1, omtB, omtA, omt1, omt12, ordA, ordB, ord1, ord2, aflR1, aflR2, aflT and aflJ;seven genes which are involved in carbohydrate metabolism: moxY, nadA, hxtA, glcA, sugR, amy1 and hxt1;three genes which are involved in nitrogen metabolism: niiA, niaD and areA;eight other genes which function was still unknown in aflatoxin biosynyhesis: cypX, cypA, cyp51A, cyp51B, lipA, alk1, hypA, amdS12 and one housekeeping gene: tub. 99 RT-PCR products of A. flavus CCRC 30290 and A. parasiticus CCRC 30172(A. flavus lacks of aflR2 gene)on the membran with 9 negative controls. 7 aflatoxigenic strains and 4 non-aflatoxigenic strains (A. flavus CCRC 30166, A. parasiticus CCRC 30227, A. sojae CCRC 30103 and A. oryzae CCRC 30120) were cultivated in YES broth for 48h and 72h, respectively. Total RNA were extracted and purified and biotin-labeled-cDNA probes were prepared by reverse transcription. The hybridization results showed that housekeeping gene (tub) and adh1 expressed in all strains incubated in YEP broth. There were 6 genes: ordA, ordB, ord1, ord2, cyp51A and cyp51B expressed only in aflatoxigenic strains and unexpressed in non-aflatoxigenic strains cultivated in YES broth. Consequently, whether aflatoxigenic isolates or potential Aspergillus species, which being able produced AF, could be decided from the presence of transcripts remains further studies.
