摘要
Proliferative responses to a panel of mitogens were compared in parallel for two sources of cells, whole blood (WE) and conventionally prepared peripheral blood mononuclear cells (PBMC), obtained from asymptomatic HIV seropositive and control subjects. Weak but statistically significant correlations of the proliferative responses were observed. Use of either lymphocyte source produced significant differences in the proliferative responses between the HIV seropositive and control subjects, but the use of WE was more powerful, with a smaller sample size being required to discriminate between the proliferative responses of the two study groups. Furthermore, proliferative responses using WE gave strong and highly significant correlations with a number of important changes in the surface marker phenotype of the lymphocyte populations in the HIV seropositive subjects including CD4, CD8, CD4:CD8 ratio and certain CD8 subsets, whereas strong correlations were not observed with the PBMC. The response of WE lymphocytes to staphylococcal enterotoxin B (SEB) was highly reproducible and provided the best discrimination between HIV-infected and control subjects. We conclude that the use of WE for measuring lymphoproliferation is easy, rapid, accurate, and discriminative for assessing and following the changes in immune function which occur in HIV seropositive subjects, applicable in the clinical as well as in the research setting.
