Because HIV and meth both affect the central nervous&nbsp;system, it&rsquo;s important&nbsp;to understand the interaction between the two.<\/p>\n<p>In collaboration with Peng Jiang, PhD, associate professor at Rutgers University, Dr. Yelamanchili&rsquo;s laboratory developed brain organoids to study such complex comorbidities.&nbsp;These &quot;mini-brains&quot; have an anatomical structure similar to human brains and are derived from induced pluripotent stem cells, which are created by taking adult human skin cells and reprogramming them to create these specialized cells. The &quot;mini-brains&quot; recapitulate various milestones of neuropathogenesis observed in an adult human brain.<\/p>\n<p>&quot;We have now specialized in culturing brain organoids with brain immune cells or microglia,&quot; Dr. Yelamanchili said. &quot;With the help of these robust models as tools, we hope not only to close some important knowledge gaps in the HIV\/drug abuse field but also expand novel therapeutic interventions.&quot;&nbsp;&nbsp;<\/p>\n<p>Karsten Bartels, MD, PhD,&nbsp;vice chair of research in UNMC&rsquo;s Department of Anesthesiology, offered his congratulations: &quot;This is truly a remarkable achievement that only comes on the shoulders of hard work and tenacity. This is well-deserved recognition and success for an exceptional scientist.&quot;<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>UNMC&#8217;s Sowmya Yelamanchili, PhD, was awarded a National Institutes of Health grant to study links in meth use and HIV-associated neurocognitive disorders.<\/p>\n","protected":false},"author":75,"featured_media":78511,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_relevanssi_hide_post":"","_relevanssi_hide_content":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","footnotes":""},"categories":[1],"tags":[],"class_list":["post-78510","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-uncategorized","topic-research","department-anesthesiology","department-unmc-today-todays-headlines","author_override-sarah-hankin-unmc-strategic-communications"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.2 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Researchers creating &#039;mini-brains&#039;
