Figure 1From: Functional regulatory immune responses against human cartilage glycoprotein-39 in health versus proinflammatory responses in rheumatoid arthritisHuman Cartilage gp-39 (HC gp-39)-specific immune reactivity in healthy donors. (a) Peripheral blood mononuclear cells from healthy donors (n = 31) react against HC gp-39 by production of IL-10 but not interferon gamma (IFN-γ). (b) 'Control' recall antigen-induced responses are dominated by IFN-γ production.Back to article page
