【 摘 要 】

References(25)Cited-By(6)Butyrate at concentrations of 200-600 μM markedly enhanced the in vitro antibody productions against sheep red blood cells (SRBC) in murine splenocytes. However, other saturated short-chain fatty acids, including acetate, propionate and valeric acid, and 4-carbon compounds such as butanol, acetoacetate and β- and γ-hydroxybutyrate had no such effects. The presence of butyrate in the early phase of the cell culture was crucial for enhancement of the response. Butyrate also augmented the antibody production in T-cell-depleted splenocytes supplemented with the culture supernatant of concanavalin A (Con A)-stimulated lymphocytes. Interleukin (IL)-2 secreted from splenocytes in response to SRBC was increased by adding butyrate to the culture, but IL-1 secretion was not affected. On the other hand, Con A or lipopolysaccharide-stimulated proliferation of splenocytes was partly depressed by the addition of butyrate, while Con A-induced IL-2 production was not effected. These findings suggest that butyrate may act on T and B cells to promote their differentiation during the process of antibody production.
