Abstract
Sixteen heat-killed bifidobacteria isolated from human intestine and a probiotic strain Lactobacillus GG were tested for their ability to influence IgE-mediated degranulation of rat basophilic leukemia (RBL-2H3) cells in vitro. The bifidobacteria suppressed IgE-mediated degranulation of RBL-2H3 cells by 1.6-56.4% in a strain-dependent manner. Bifidobacteria from healthy infants expressed high inhibitory effects on IgE-mediated degranulation (41-55%), while those from allergic infants varied greatly in their effects against degranulation. Bifidobacteria taxonomically identified as Bifidobacterium bifidum exhibited much stronger inhibitory effects against IgE-mediated degranulation than those taxonomically identified as B. adolescentis (P < 0.05).These results indicate that the intestinal bifidobacteria might be one of factors influencing IgE-mediated allergic responses.Entities:
