タイトル Restoration by dietary glutamine of reduced tumor necrosis factor production in a low-protein-diet-fed rat model.
ジャーナル Biosci Biotechnol Biochem
Abstract Tumor necrosis factor-alpha (TNF) production by peritoneal macrophages and its dietary modification were investigated by using rats fed on a low-protein diet. The rats were given a 20% casein (control) diet or a 3% casein diet for 21 days, and TNF production was measured in activated macrophages of these animals. TNF production was significantly lower in macrophages from rats fed on the low-protein diet than that in macrophages from rats fed on the control diet. Oral administration of a cabbage extract, a known modulator of TNF production, to the low-protein-diet-fed rats significantly enhanced TNF production by macrophages. Glutamine supplementation to the low-protein diet significantly enhanced TNF production as well as TNF mRNA expression. These results indicate that the 3%-casein-diet-fed rat would be useful as a model for reduced TNF production in protein malnutrition. These results also suggest that glutamine administration restored the reduced TNF production associated with protein malnutrition.
