Description:
Nucleoside reverse transcriptase inhibitors (NRTIs) are mainstay therapeutics for HIV that block retrovirus replication. Alu (an endogenous retroelement that also requires reverse transcriptase for its life cycle)-derived RNAs activate P2X7 and the NLRP3 inflammasome to cause cell death of the retinal pigment epithelium in geographic atrophy, a type of age-related macular degeneration. We found that NRTIs inhibit P2X7-mediated NLRP3 inflammasome activation independent of reverse transcriptase inhibition. Multiple approved and clinically relevant NRTIs prevented caspase-1 activation, the effector of the NLRP3 inflammasome, induced by Alu RNA. NRTIs were efficacious in mouse models of geographic atrophy, choroidal neovascularization, graft-versus-host disease, and sterile liver inflammation. Our findings suggest that NRTIs are ripe for drug repurposing in P2X7-driven diseases.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4274127/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉 〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4274127/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fowler, Benjamin J -- Gelfand, Bradley D -- Kim, Younghee -- Kerur, Nagaraj -- Tarallo, Valeria -- Hirano, Yoshio -- Amarnath, Shoba -- Fowler, Daniel H -- Radwan, Marta -- Young, Mark T -- Pittman, Keir -- Kubes, Paul -- Agarwal, Hitesh K -- Parang, Keykavous -- Hinton, David R -- Bastos-Carvalho, Ana -- Li, Shengjian -- Yasuma, Tetsuhiro -- Mizutani, Takeshi -- Yasuma, Reo -- Wright, Charles -- Ambati, Jayakrishna -- BB/J017345/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- DP1 GM114862/GM/NIGMS NIH HHS/ -- DP1GM114862/DP/NCCDPHP CDC HHS/ -- K99 EY024336/EY/NEI NIH HHS/ -- K99EY024336/EY/NEI NIH HHS/ -- P30EY003040/EY/NEI NIH HHS/ -- R01 EY018350/EY/NEI NIH HHS/ -- R01 EY018836/EY/NEI NIH HHS/ -- R01 EY020672/EY/NEI NIH HHS/ -- R01 EY022238/EY/NEI NIH HHS/ -- R01 EY024068/EY/NEI NIH HHS/ -- R01EY001545/EY/NEI NIH HHS/ -- R01EY018350/EY/NEI NIH HHS/ -- R01EY018836/EY/NEI NIH HHS/ -- R01EY020672/EY/NEI NIH HHS/ -- R01EY022238/EY/NEI NIH HHS/ -- R01EY024068/EY/NEI NIH HHS/ -- T32HL091812/HL/NHLBI NIH HHS/ -- TL1 RR033172/RR/NCRR NIH HHS/ -- TL1 TR000115/TR/NCATS NIH HHS/ -- UL1 RR033173/RR/NCRR NIH HHS/ -- UL1 TR000117/TR/NCATS NIH HHS/ -- UL1RR033173/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2014 Nov 21;346(6212):1000-3. doi: 10.1126/science.1261754.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ophthalmology and Visual Sciences, University of Kentucky, Lexington, KY 40536, USA.
