1 We hypothesized that isoflurane, sevoflurane, and desflurane would exert variable degrees of neurotoxicity in vitro and in vivo via activation of the p75 neurotrophin receptor (p75). Isoflurane PC4 and SFRS1 interacting protein 1 Homo sapiens
2 We hypothesized that isoflurane, sevoflurane, and desflurane would exert variable degrees of neurotoxicity in vitro and in vivo via activation of the p75 neurotrophin receptor (p75). Isoflurane PC4 and SFRS1 interacting protein 1 Homo sapiens
3 Pharmacological inhibition or siRNA knockdown of p75 counteracted the aggravating effects of isoflurane. Isoflurane PC4 and SFRS1 interacting protein 1 Homo sapiens
4 Isoflurane increased RGC damage in vivo (IRI 1479 RGC/mm(2) [1311/1697] versus IRI + isoflurane 1170 [1093/1211], P = 0.03), which was counteracted by p75-inhibition via TAT-pep5 (P = 0.02). Isoflurane PC4 and SFRS1 interacting protein 1 Homo sapiens
5 CONCLUSIONS: Isoflurane but not sevoflurane or desflurane postexposure aggravates neurotoxicity in preinjured neurons via activation of p75 and NF-kappaB. Isoflurane PC4 and SFRS1 interacting protein 1 Homo sapiens
