the synthesis and secretion of il-1 by mononuclear phagocytes at sites of inflammation and immune reactions in vivo could potentially serve as a signal for fibroblasts to synthesize ha , which in turn could serve to facilitate and modulate reparative and immune processes by virtue of its ability to alter cell-cell , cell matrix , and cell-membrane receptor interactions .
