Interleukin 1β induces the expression of interleukin 6 in rat intestinal smooth muscle cells

BACKGROUND/AIMS: The increased expression of several cytokines, including interleukin 6 (IL-6), has recently been reported in a study of the longitudinal muscle and myenteric plexus layers of rat intestine following Trichinella spiralis infection. However, the putative cellular sources and the mechanism underlying the induction of IL-6 in these tissues are presently unknown. The aim of this study was to examine the ability of cultured smooth …
