B cell lines from a subset of patients with common variable immunodeficiency undergo enhanced apoptosis associated with an increased display of CD95 (Apo-1/fas), diminished CD38 expression, and decreased IgG and IgA production.

Abstract excerpt

Investigation of common variable immunodeficiency (CVI) is hampered by lack of a suitable in vitro models. We have developed EBV-transformed B lymphoblastoid cell lines from a selected subset of CVI patients and characterized them for phenotypic and functional properties that provide evidence for their representation of the CVI disease state. B cell lines from the patients expressed increased levels of sIgM and...
