B-cell subsets and platelet counts in HIV-1 seropositive subjects
A subset of B lymphocytes positive for the CD5 antigen have been implicated in several autoimmune disorders. To investigate their role in human immunodeficiency virus type 1 (HIV-1) infection, we studied peripheral-blood B and T lymphocytes from HIV-1-positive patients with (n=13) and without (n=18)...

Zusammenfassung: | A subset of B lymphocytes positive for the CD5 antigen have been implicated in several autoimmune disorders. To investigate their role in human immunodeficiency virus type 1 (HIV-1) infection, we studied peripheral-blood B and T lymphocytes from HIV-1-positive patients with (n=13) and without (n=18) thrombocytopenia, 8 patients with classic autoimmune thrombocytopenia, and 16 healthy controls. The proportion of CD5-positive B cells was significantly higher in the HIV-1-positive thrombocytopenic patients than in the healthy controls, as a result of both higher numbers of CD5-positive B cells and lower numbers of CD5-negative B cells. Platelet count was positively correlated with CD5-negative B-cell count (
