To determine whether non-Vγ9 γδ T cells produce IL-10 in patients with falciparum malaria, we used intracellular staining for IL-10 and confirmed that IL-10 was indeed produced in non-Vγ9 γδ T cells after whole PBMCs were cultured for 10 days. The gene discussed is IL10; the disease is Plasmodium falciparum malaria.
