Hence, there is a continuous need for identification of new antiviral targets. HIV exploits specific host proteins also known as HIV-dependency factors during its replication inside the cell. Potassium channels play a crucial role in the life cycle of several viruses by modulating ion homeostasis, cell signaling, cell cycle, and cell death. In this study, using pharmacological tools, we have identified that HIV utilizes distinct cellular potassium channels at various steps in its life cycle. Members of inwardly rectifying potassium (K<jats:sub>ir<\/jats:sub>) channel family, G protein-coupled (GIRK), and ATP-sensitive (K<jats:sub>ATP<\/jats:sub>) are involved in HIV entry. Blocking these channels using specific inhibitors reduces HIV entry. Another member, K<jats:sub>ir<\/jats:sub> 1.1 plays a role post entry as inhibiting this channel inhibits virus production and release. These inhibitors are not toxic to the cells at the concentration used in the study. We have further identified the possible mechanism through which these potassium channels regulate HIV entry by using a slow-response potential-sensitive probe DIBAC4(3) and have observed that blocking these potassium channels inhibits membrane depolarization which then inhibits HIV entry and virus release as well. These results demonstrate for the first time, the important role of K<jats:sub>ir<\/jats:sub> channel members in HIV-1 infection and suggest that these K<jats:sup>+<\/jats:sup> channels could serve as a safe therapeutic target for treatment of HIV\/AIDS.<\/jats:p>","DOI":"10.1038\/s41598-019-40968-x","type":"journal-article","created":{"date-parts":[[2019,3,11]],"date-time":"2019-03-11T11:03:05Z","timestamp":1552302185000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["G protein-coupled and ATP-sensitive inwardly rectifying potassium ion channels are essential for HIV entry"],"prefix":"10.1038","volume":"9","author":[{"given":"Ravi C.","family":"Dubey","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nawneet","family":"Mishra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ritu","family":"Gaur","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2019,3,11]]},"reference":[{"key":"40968_CR1","unstructured":"U.S. Food and Drug Administration.
