Lymphocyte proliferation induced with phytohemagglutinin, concanavalin A and pokeweed mitogen in human subjects fed 0, 2 or 8 mg astaxanthin daily for 8 wk. Responses to high concentrations of mitogens (10 mg phytohemmaglutinin/L, 10 mg concanavalin A/L and 5 mg pokeweed mitogen/L final concentration) are shown. a, b Different letters represent significant treatment differences (P < 0.05) as analyzed by protected LSD test.
