文摘Although chronic gastrointestinal dysmotility syndromes are a common worldwide health problem,underlying causes for these disorders are poorly understood.We show that flavivirus infection of enteric neurons leads to acute neuronal injury and cell death,inflammation,bowel dilation,and slowing of intestinal transit in mice.Flavivirus-primed CD8+T cells promote these phenotypes,as their absence diminished enteric neuron injury and intestinal transit delays,and their adoptive transfer reestablished dysmotility after flavivirus infection.
