摘要: Vitamin D receptor (VDR) knockout (KO) mice had fewer Citrobacter rodentium in the feces than wild-type (WT) and kinetics of clearance was faster VDR KO WT mice. more interleukin-22 (IL-22)-producing innate lymphoid cells (ILCs) antibacterial peptides The increased ILCs a cell-autonomous effect deficiency on ILC frequencies. Bone marrow (BM) transplantation from into resulted higher colonization resistance Disruption gut microbiota using antibiotics reversed to C. infection. Confirming role mice, transfer germ-free resistance. Once overcome, susceptibility rodentium. expression is regulator frequencies, IL-22, dysbiosis, susceptibility.
