Abstract:
:During the acute phase response, synthesis of C-reactive protein and serum amyloid A is increased. To investigate whether the enhanced synthesis of these proteins are due to stimulatory effect of inflammatory mediators such as interleukin-1 (IL-1) and interleukin-6 (IL-6) produced by macrophages and monocytes, primary cultures of adult human hepatocytes were exposed to recombinant (r)IL-1, rIL-6 or rIL-1 and monospecific anti rIL-6 antibodies in the presence of 1 microM dexamethasone. The findings indicate that rIL-1 and rIL-6 both stimulate the liver synthesis of C-reactive protein and serum amyloid A, however monospecific anti rIL-6 antibodies reduce the stimulatory effect of rIL-1 on the synthesis of these proteins. These findings suggest that IL-6 plays a key role in the stimulation of synthesis of serum amyloid A and C-reactive protein by the human liver cells.
