[Resistant starches and immune system].

Different absorbtion level is inherent capacities for natural, resistant and hydrolized starches to regulate a volume of non-hydrolyzed starches in colon. This regulates an interaction with intestinal microflora to produce the short chain fatty acids and other bio-active compounds. The T- and B-lymphocyte receptors are targets for starches to disrupt the number and density of plasma membrane receptors CD3, CD4, and CD8. All starches regulate the expression of adhesion molecules LFA-1 and ICAM-1, as well as receptor Mac-1. Maize starch increases the level of spontaneous and ceramide-dependent apoptosis in thymic and spleen cells of experimental animals.
