Small intestine microbiota development prevents early-life adiposity via IL-22-mediated intestinal PPARα suppression

Catherine D. Shelton, Camila Bernardo de Brito, Vinícius Dias Nirello, Nicole Kirchoff, Julia Lane, Joanna Olivas, Darian T. Carroll, Derek Armstrong, Matthew W. Rhee, Merrygay N. James, Louise Lantier, Marco Aurélio Ramirez Vinolo, Mariana Xavier Byndloss
