Abstract
The failure of B cells from CVI patients to secrete normal amounts of antibodies has been attributed either to an intrinsic B cell defect or to a lack of cooperation from T cells. In an attempt to improve the definition of the origin of this defect in one of the main cellular compartments, we studied the ability of helper CD4 cells and their CD4 CD45RO subpopulation from CVI patients to secrete interleukins (IL-2 and IL-4) in response to mitogen stimulation. We found that CD4 and CD4 CD45RO cells from some patients secrete abnormal amounts of interleukins (in general low levels of IL-2 and high levels of IL-4) upon stimulation with pokeweed mitogen (PWM). These irregularities may contribute to the defective differentiation of B cells in these patients.
