- 요약Populations of microbes that reside on environmentally exposed surfaces of the body, termed the microbiota, perform a variety of functions that are beneficial to the host. The contribution of these microbial populations to the development of the host immune system continues to be explored and appreciated. The microbiota is a potent producer of Toll-like receptor ligands, these ligands can escape the restrictions of the gastrointestinal tract and enter the circulation where they can interact with peripheral cells expressing Toll-like receptors. The contribution of Toll-like receptor signaling in peripheral immune cells was assessed in splenic CD4+ T cells. Splenic CD4+ T cells from mice devoid of microbes were found to express high levels of the proapoptotic gene Erdr1. When treated with Pam3Cysk, a Toll-like receptor 2 ligand, Erdr1 was suppressed through a NF-kB dependent manner. When Erdr1 was overexpressed, CD4+ T cell death was enhanced in a Fas-dependent pathway, the modulation of Erdr1 could enhance or diminish the CD4+ T cell response in both a model of ovalbumin immunization and experimental autoimmune encephalomyelitis. The microbiota has been shown to influence the outcome of viral infections but limited work has explored the impact of the microbiota on viral infection of the central nervous system. Using the neurotropic mouse hepatitis virus model of infection, we assessed the outcome of viral infection in the absence of the microbiota. Mice devoid of microbes exhibited enhanced disease and an inability tocontrol viral replication in the central nervous system. While disease in this model is due to the presence of CD4+ and CD8+ T cells, these cells from mice devoid of microbes did not exhibit intrinsic defects. Rather, microglia from germfree or mice treated with antibiotics from a young age were deficient in their ability to express antigen presentation molecules and stimulate antiviral response. Administration of Toll-like receptor ligands was sufficient to protect germfree mice from enhanced disease and MyD88 signaling in the central nervous system was found to be crucial to the development of microglia.
