Epstein-Barr virus (EBV)-positive Hodgkin's and Reed-Sternberg (HRS) cells express the virus-encoded latent membrane proteins LMP1 and LMP2 that could serve as rejection targets in Hodgkin's disease (HD). To examine whether EBV-triggered reactivities can be detected in the tumor, we have compared cytokine mRNA expression, cell phenotype, and cytotoxic(More)
MG is an autoimmune disease in which T cells specific to T-cell epitopes of the human acetylcholine receptor play a role. We have identified two peptides, p195-212 and p259-271, of the human acetylcholine receptor alpha-subunit, to which PBLs of MG patients responded by proliferation. Nevertheless, proliferation assays are relatively complicated to perform(More)

The Moroccan Jewish community living in Israel shows a relatively large genetic distance from other North African Jewish communities. In this work the polymorphism of HLA class I and class II determinants, as defined by serology and oligotyping, is analyzed in 113 healthy unrelated Jews of Moroccan stock. The class I antigens HLA-A1, -B44, and -Cw7 showed(More)
BACKGROUND Psoriasis vulgaris was reported to be associated with a specific alanine residue at position 73 of HLA-C alleles in Japanese patients. OBJECTIVE Our purpose was to determine the role of HLA genes in susceptibility to psoriasis vulgaris in the Israeli Jewish population. METHODS Twenty-eight Israeli patients were analyzed for their HLA class I(More)
On the basis of data collected during the 12th International Histocompatibility Workshop, we postulated a possible linkage disequilibrium between the TAP1C allele and the DRB1*1104-DQA1*0103-DQB1*0603 haplotype characteristic of Ashkenazi Jews. In order to confirm and extend this preliminary observation, a group of 34 subjects carrying this haplotype was(More)
The Jewish people comprise two major groups, one encompassing the Jews of Ashkenazi (Central and Eastern European) origin and the other including those of Sephardic (Middle Eastern and North African) descent. To the latter belong the Jews of Moroccan stock, who form the largest Jewish subgroup among the non-Ashkenazi population living in Israel. As the(More)
HLA class I and class II were investigated in 30 Israeli patients with invasive squamous cell carcinoma of the cervix and compared to healthy controls. None of the studied serological specificities were found to be associated with the disease. Genomic DNA from the patients was amplified by PCR, dot-blotted and hybridized with sequence specific(More)
Forty-three patients with rheumatoid arthritis (RA) were studied for their ability to respond to the synthetic polypeptide antigen (T, G)-A-L as measured by the production of a T cell helper factor by their antigen activated T cells. Sixteen patients (37%) responded to (T, G)-A-L by the production of an antigen specific helper T cell factor, a percentage(More)
