Fig. 3From: The mechanisms of nerve injury caused by viral infection in the occurrence of gastrointestinal motility disorder-related diseasesSome specific mechanisms of viral infection. A. VZV infects unmyelinated sensory nerve endings and is transported in a retrograde manner. B. RTX prevents HSV-1 entry into the ENS by disrupting peripheral TRPV1 nociceptors. C. HIV Tat promotes the LPS-TLR4-MyD88-NF-κB pathway through TLR4, thereby promoting the release of inflammatory factorsBack to article page
