摘要: Abstract Small intestinal intraepithelial lymphocyte (IEL) function has been studied in Vitamin A deficient rats. Weanling Wistar rats were pair-fed a diet for 6–9 weeks period, at which time the (Vit A-) showed significant reduction serum and liver retinol concentration as compared to their control A+) The yield of IEL proliferative response Concanavalin (Con A) significantly reduced Vit A- Phenotypic analysis population using monoclonal antibodies specific rat T lymphocytes its subsets revealed that percentages total helper cell subset decreased However, percentage cells expressing cytotoxic/suppressor phenotype was unaltered These results suggest depressed immune mucosal associated small intestine deficiency.
