Influence of the microbiome on solid organ transplant survival.

The microbiome is an environmental factor in intricate symbiotic relationship with its hosts' immune system, potentially shaping anticancer immunity, autoimmunity, and transplant responses. The focus of this review is to discuss recent findings tying the microbiota to transplant outcomes and alloimmunity. The microbiota changes dynamically following transplantation, but whether these changes affect transplant outcomes can be difficult to parse out. New data reveal effects of the microbiota locally, as well as systemically, depending on the mucosal/epithelial surface colonized, the specific commensal communities present and the nature of microbial-derived molecules produced. These complex interactions result in the microbiota potentially impacting transplantation at different levels, including modulation of donor and/or recipient cells, alterations in the priming and/or effector phases of the alloimmune response, availability or metabolism of immunosuppressive drugs, transplant fate or post-transplant complications.
