Autologous mixed lymphocyte reaction in man. IV. Decreased autologous mixed lymphocyte culture response in patients with common variable immunodeficiency.
The autologous mixed lymphocyte reaction (AMLR) was studied in 18 patients with common variable immunodeficiency. The AMLR was decreased in 10 of 18 (55%) patients with common variable immunodeficiency compared to healthy controls. In allogeneic MLR, T cells from patients were found to be poor responders, and non-T cells poor stimulators, compared to allogeneic MLR between healthy normal controls. In allogeneic MLR, B cells (B cells + null cells) from patients were poor stimulators, whereas macrophages stimulated normally compared to controls. The deficient AMLR could be one of the mechanisms responsible for the increased risk of autoimmune phenomena in a subset of patients with primary immunodeficiency.
