“…Most of these interactions involve the binding of CRP to the phosphorylcholine ligand, which is essential for CRP to function as an opsonin (Kilpatrick and Volanakis, 1991;Kushner, 1991). Human CRP has been shown to affect monocyte and macrophage function by modulating the generation of superoxide anion and tumouricidal activity (Hokama et al, 1986;Zahedi and Mortensen, 1986;Barna et al, 1987Barna et al, , 1988Buchta et al, 1987;Gautam et al, 1987;Miyagawa et al, 1988a;Nunomura et al, 1990;Dobrinich and Spagnuolo, 1991). There are reports suggesting that human CRP peptides generated from the action ofneutrophil and/or monocyte proteases on human CRP modulate the phagocytic function of the immune cells (Buchta et al, 1986;Robey et al, 1987;Shephard et al, 19%9).…”
