Experimental evidence for the involvement of F0/F1 ATPase and subsequent P2Y12 receptor activation in prothymosin alpha-induced protection of retinal ischemic damage
The inhibition of retinal ischemia-induced damage by post-ischemic prothymosin alpha (ProTα) was not affected in toll-like receptor 4 knockout (TLR4−/−) mice but blocked by the pretreatment with antibody against F0/F1 ATPase α- or β-subunit, novel candidate for ProTα-receptor. In addition to the pre...

| Summary: | The inhibition of retinal ischemia-induced damage by post-ischemic prothymosin alpha (ProTα) was not affected in toll-like receptor 4 knockout (TLR4−/−) mice but blocked by the pretreatment with antibody against F0/F1 ATPase α- or β-subunit, novel candidate for ProTα-receptor. In addition to the previous observation of ProTα-induced ATP release from cells, the present study showed a ProTα-induced enhancement of ATP hydrolysis activity of recombinant ATP5A1/5B complex. As the protection of retinal function by post-ischemic ProTα was abolished by anti-P2Y12 antibody, the activation of F0/F1 ATPase and subsequent P2Y12 receptor system may play roles in beneficial actions by post-ischemic ProTα. |
