...Mukesh Patel; Lee Faulkner; David R. Katz; Paul M. Brickell The c-fgr proto-oncogene, which is a member of the c-src gene family, encodes the cytoplasmic tyrosine kinase p55 c-fgr . Expression of the c-fgr gene is activated in human B lymphocytes following infection with Epstein-Barr virus...

... product) and Lewis T lymphocyte receptors with the same specificity. We found that B lymphocytes bear unique idiotypic determinants which are not present on the corresponding T lymphocytes. T cell unique (not shared by B lymphocytes) idiotypes were so far not detected. T cells share idiotypic determinants...

... and testosterone on cell cycling and apoptosis in B lymphocyte cell lines, suggesting that estrogen and testosterone are inhibitory to T but not B cell lines. In comparison, progesterone induced cytostasis and modestly increased apoptosis in both T and B cell lines. Estrogen and testosterone were not antagonistic...

... lymphocytes in HIV infection as surrogate markers in this cell population of certain functional aspects that could be easily measured. We investigated the level of expression of a series of constitutive surface markers in B lymphocytes (HLA-DR, CD19, CD20, CD21, CD22) from 30 HIV-seropositive adult patients...
