Abstract
We examined 19 non-Hodgkin’s lymphoma patients for their responsiveness to lectin stimulation, as measured by T cell proliferative response and p55kDa-IL2R expression. Our results indicate that both these responses were remarkably depressed in non-Hodgkin’s lymphoma patients and the deficiency of lectin-induced p55kDa-IL2R expression correlated closely with the reductions in the lectin-induced T cell proliferative responses. The evidence that costimulation with PMA can partially overcome the IL2R defect might allow us to localize the cellular defects and rationally design chemotherapeutic agents corrective for these patients’ poor p55kDa-IL2R inducibility.
