Повний текст джерелаMultiple sclerosis (MS) is an inflammatory autoimmune disease of the central nervous system (CNS) which typical feature is the plaques of demyelination. The factor triggering the disease is still unknown, but the most diffuse opinion is that the autoimmune reaction is due to a new contact with environmental factors, like virus, that mimic self molecules (molecular mimicry). MS is a T- cell mediated disease. These cells activated by myelin antigens activate, in turn, B lymphocytes, macrophages and cytotoxic lymphocytes which strongly damage oligodendrocytes and neurons, both directly and through complement activation, leading to an inhibition of nervous conductivity in CNS. In this project, MS is studied through an “epitomic” approach by means of the construction of epitope phage display libraries, obtained by cloning cDNAs derived from CNS tissue. These collections of billions of different phages displaying different polypeptides on their surface give the total representation of the CNS expression pattern and are useful for the selection against MS serum and CSFs, in order to identify potential autoimmune epitopes and the relatives auto-antibodies. The choice of phage display technology as tool to investigate MS autoimmune response depends on the possibility to couple the phenotype to genotype in a selectable format. Selection of the phages on the basis of the binding properties of the polypeptide displayed on the surface, simultaneously results in the isolation of the gene encoding the polypeptide. In order to obtain the epitope phage display libraries, two different versions of a new vector, called pEP1 and pEP2 respectively, for the selection of the cDNA fragments cloned in the correct open reading frame (ORF) were designed. A well characterized vector for the ORF selection, previously described by Zacchi and colleagues (2003), was used as backbone and modified in two alternative ways on its original polylinker to improve the cloning efficiency. In addition, for its oriented cloning system, pEP2 was able to give a greater ratio of “in frame”/ “out of frame” clones (1/9 rather than 1/18) than pEP1. After their validation, the new vectors were employed to generate two kinds of cDNA phage display libraries: pEP1 was tested with the construction of single myelin genes (myelin basic protein, MBP; and myelin oligodendrocyte glycoprotein, MOG) mini-libraries; while the more advanced pEP2 was used to create a total human brain library. A first question was related to the kind of epitope recognized by autoantibodies in MS. Generally, autoantibodies recognize both linear and conformational epitope, but at present the conformational epitopes of myelin proteins have not been identified. We have set a system to make minilibraries from single gene through the fragmentation of the gene of interest with nuclease protection by means of archibacteria histones. In this way it’s possible to obtain phage display libraries of overlapping fragments of the same gene useful to define the precise epitope recognized by a biological sample. For the project, human MBP and MOG mini-libraries were obtained and characterized through PCR analysis and enzymatic fingerprinting. By sequencing of 30 randomly picked clones for both mini-libraries, a set of overlapping fragments which gave a total representation of mbp and mog gene, was respectively found. MBP mini-library was subjected to two selections: against the serum and the CSF of a patient with a Clinically Isolated Syndrome (CIS), diagnosed after a first clinically episode of MS symptoms. Instead, MOG mini-library was selected against a Relapsing Remitting (RR) serum of a MS patient. To identify the more reactive clones, 95 clones from each last round of selection were randomly picked and subjected to a phage-ELISA test. Panning the hMBP mini-library with CIS serum and CSF, some distinct epitopes of the protein were identified, suggesting a specific pattern of recognition with some overlapping regions in both the CIS samples. Among the epitopes recognized, was identified the more immunogenic region of hMBP (a.a. 85-96). In the case of hMOG mini-library against RR serum, selected phage clones shared the epitope corresponding to a.a. 33-104 of the protein, which is localized inside the more immunogenic region of hMOG. A cDNA phage display library which should contain all the potential auto-antigens of the CNS is a useful tool to perform a serological analysis of MS sera and CSFs, in order to identify the epitopes involved in the immune response and to identify subclinical conditions of patients. With these purposes, a human brain phage display library was produced. Starting from human brain mRNA, a new protocol for the cDNA production was set. Employing the “OrientExpress Random Primers” (Novagen), an orientated synthesis of the cDNA was obtained. Following the ligation to the vector (digested pEP2), a human brain library of 1.35x10^5 individual clones selected for the presence of ORF inserts was produced. Through PCR analysis, enzymatic fingerprinting and sequencing of randomly picked clones a library diversity of 90% was estimated. The library was employed for three distinct selections: 1). against IgGs purified from a pool of RRMS sera; 2). against a pool of Secondary Progressive (SP) MS sera; and 3). against a pool of MS CSFs. From the last round of each selection test were respectively picked 190, 95 and 50 clones. These randomly picked clones were checked by phage-ELISA to identify those more reactive. The positive clones were respectively 34%, 16% and 50% on the total. Interestingly, some clones were shared among the selections and it was identified less clone diversity in the selection against CSFs pool. The reactivity of some selected clones, as phages, as recombinant protein or as synthetic peptides, was tested in ELISA in order to establish the sensibility and specificity in discriminating MS and other neurological diseases (OND). The ELISAs on "omissis patent pending" peptide resulted particularly predictive (LR+ 12.2) with a sensitivity and specificity of discrimination of 31.7% and 97.4%, respectively. The final aim of the project was in providing new tools to investigate the antibody response in MS and in the improvement of the currently used diagnostic tests through the detection of new potential markers of the disease. At the moment there are not validated biomarkers of MS. The new candidate autoantigens identified in this study could be one of those and integrate the current diagnostic method of MS.
