HIV still is able to replicate in these reservoirs, despite being driven to undetectable levels in blood.<\/p>\n<p>But now, the team has published its latest discoveries in an October 2017 <a href=\"https:\/\/www.nature.com\/articles\/nm.4411\">study in Nature Medicine<\/a>.<\/p>\n<p>Dr. Fletcher said the study had three takeaway findings:<\/p>\n<ul>\n<li>Ninety-nine percent of HIV-infected cells are found in lymphoid tissue such as lymph nodes, spleen, and the gastrointestinal tract;\n<li>HIV-infected cells in these reservoir tissues were making viral particles even during anti-HIV therapy;\n<li>The concentrations of antiretroviral drugs in these tissues were much lower than in the blood, and apparently suboptimal (ineffective).<\/ul>\n<p>The antiretroviral drugs that were keeping the virus at bay weren&#8217;t effectively reaching these &#8220;hideout&#8221; areas in order to fully knock out the virus, and these hideout areas, or reservoirs, are where most of the virus is. Having identified the problem makes a solution possible, Dr. Fletcher said.<\/p>\n<p>&#8220;This finding identifies a key objective to achieve the goal of stopping virus production,&#8221; Dr. Fletcher said. &#8220;We need better drugs that get into the lymphoid tissue reservoir.&#8221;<\/p>\n<p>Enhancing drug delivery is a focus of the Center for Drug Delivery and Nanomedicine at UNMC, which includes scientists from the Colleges of Pharmacy and Medicine. Dr. Fletcher is among a select few deans of pharmacy nationwide to maintain an active research lab. He recently announced that after a decade leading UNMC&#8217;s College of Pharmacy, he is stepping down as dean to further concentrate on teaching and research.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Study was recently published in the journal
