Synergistic action of beta-glucan and platelets on interleukin-8 production by human peripheral blood leukocytes.

The effects of human platelets on interleukin (IL)-8 production from human peripheral blood mononuclear cells (PBMCs) and polymorphonuclear leukocytes (PMNs) stimulated with the fungal (1-->3)-beta-D-glucan schizophyllan ( SPG) were examined using ELISA. PBMCs/PMNs in the presence of platelets and SPG enhanced IL-8 production in comparison with those in the presence of either platelets or SPG. IL-8 production was dependent on the concentration of platelets and incubation time, and the activity reached the maximal level at 18 h of incubation. These activities were also observed with the addition of platelets prestimulated with SPG to PBMCs. Addition of SPG directly enhanced expression of P-selectin on platelet membrane surfaces. These results suggest that platelets play a key role in the cytokine production of leukocytes induced by fungal (1-->3)-beta-D-glucans and might be mediated, at least in part, by P-selectin.[1]
