S. Houldsworth et al., PNEUMOLYSIN STIMULATES PRODUCTION OF TUMOR-NECROSIS-FACTOR-ALPHA AND INTERLEUKIN-1-BETA BY HUMAN MONONUCLEAR PHAGOCYTES, Infection and immunity, 62(4), 1994, pp. 1501-1503
Human peripheral blood monocytes and a human monocyte cell line were e
xposed to the toxin pneumolysin. Pneumolysin-exposed cells produced si
gnificantly larger amounts of tumor necrosis factor alpha and interleu
kin-1 beta than cells not exposed to the toxin. The viability of cells
was not affected by the concentrations of pneumolysin used in the exp
eriments.
