Bioenergetic metabolism varies during cell differentiation, but details of B cell metabolism remain unclear. Here, we show the metabolic changes during B cell differentiation in the intestine, where B cells differentiate into IgA(+) plasma cells (PCs). Naive B cells in the Peyer's patches (PPs) and IgA(+) PCs in the intestinal lamina propria (iLP) both used the tricarboxylic acid (TCA) cycle, but only IgA(+) PCs underwent glycolysis. These metabolic differences reflected their dependencies on vitamin B-1, an essential cofactor for the TCA cycle. Indeed, the diminished activity of the TCA cycle after dietary vitamin B1 depletion decreased the number of naive B cells in PPs without affecting IgA(+) PCs in the iLP. The maintenance of naive B cells by dietary vitamin B1 was required to induce-but not maintain-intestinal IgA responses against oral antigens. These findings reveal the diet-mediated maintenance of B cell immunometabolism in organized and diffuse intestinal tissues.
