Responses to cytokines entail synthesis of substances rich in cysteine and glycine, such as glutathione (GSH), metallothionein and some plasma proteins. To examine the importance of an adequate supply of cysteine and glycine, we fed rats a low protein diet supplemented with L-cysteine and glycine, separately or in combination, or L-alanine, or a high protein diet for 1 wk before injection with tumor necrosis factor alpha (TNF) or saline. The high protein diet-fed group had greater liver weight and zinc and GSH concentrations after TNF than the group fed the low protein diet supplemented with alanine. Glycine and cysteine supplementation resulted in greater liver weight after TNF treatment than did alanine supplementation. Cysteine supplementation had a similar influence on GSH concentration. Ceruloplasmin, alpha-2-macroglobulin and alpha-1-acid glycoprotein were higher in TNF-treated rats than in saline controls in each dietary group. However, feeding supplementary glycine and cysteine and the high protein diet often resulted in different values than seen in animals fed the low protein diet supplemented with alanine. Paradoxically, lower ceruloplasmin concentrations were observed in animals fed the former diets than in those fed the latter. alpha-2-Macroglobulin concentration was lower in all animals fed low protein diets than in those fed the high protein diet. alpha-1-Acid glycoprotein was lowest in groups fed cysteine-supplemented diets and highest in the glycine-supplemented group.(ABSTRACT TRUNCATED AT 250 WORDS)
