class="title"> Abstract </h2> <div class="abstract-content selected" id="eng-abstract"> <p> Human immunodeficiency virus (HIV) infection may cause a dementing illness. HIV-mediated dementia is clinically and pathologically correlated with the infiltration of activated macrophages and elevated levels of tumor necrosis factor (TNF)-alpha, both of which occur in an environment of small numbers of infected cells. We examined the possibility that HIV protein Tat, which is released extracellularly from infected cells, may induce the production of TNF-alpha. Tat induced TNF-alpha mRNA and protein production dose-dependently, primarily in macrophages but also in astrocytic cells. The TNF-alpha induction was NF-kappaB-dependent and could be eliminated by inhibiting protein kinase A or protein tyrosine kinase activity. In addition, Tat-induced TNF-alpha release was also linked to phospholipase C activation. However, Tat effects were independent of protein kinase C. These observations suggest that Tat may provide an important link between HIV and macrophage/glial cell activation and suggest new therapeutic approaches for HIV dementia. </p> </div> </div> <p class="disclaimer" id="disclaimer"> <a href="/disclaimer/" target="_blank" ga_category="literature_resources" ga_action="disclaimer_link" ga_label="under_abstract">PubMed Disclaimer</a> </p> <div class="similar-articles" id="similar"> <h2 class="title"> Similar articles </h2> <ul class="articles-list" id="similar-articles-list"> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/9730685/" ref="article_id=9730685&linksrc=similar_articles_link&ordinalpos=1" data-ga-category="similar_article" data-ga-action="9730685" data-ga-label=""> HIV-1 tat molecular diversity and induction of TNF-alpha: implications for HIV-induced neurological disease. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Mayne M, Bratanich AC, Chen P, Rana F, Nath A, Power C.</span> <span class="docsum-authors short-authors">Mayne M, et al.</span> <span class="docsum-journal-citation full-journal-citation">Neuroimmunomodulation. 1998 May-Aug;5(3-4):184-92. doi: 10.1159/000026336.</span> <span class="docsum-journal-citation short-journal-citation">Neuroimmunomodulation. 1998.</span> <span class="citation-part">PMID: <span class="docsum-pmid">9730685</span></span> </div> </div> </li> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/8709193/" ref="article_id=8709193&linksrc=similar_articles_link&ordinalpos=2" data-ga-category="similar_article" data-ga-action="8709193" data-ga-label=""> Transdominant mutants of I kappa B alpha block Tat-tumor necrosis factor synergistic activation of human immunodeficiency virus type 1 gene expression and virus multiplication. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Beauparlant P, Kwon H, Clarke M, Lin R, Sonenberg N, Wainberg M, Hiscott J.</span> <span class="docsum-authors short-authors">Beauparlant P, et al.</span> <span class="docsum-journal-citation full-journal-citation">J Virol. 1996 Sep;70(9):5777-85. doi: 10.1128/JVI.70.9.5777-5785.1996.</span> <span class="docsum-journal-citation short-journal-citation">J Virol. 1996.</span> <span class="citation-part">PMID: <span class="docsum-pmid">8709193</span></span> <span class="free-resources spaced-citation-item citation-part">Free PMC article.</span> </div> </div> </li> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/11522182/" ref="article_id=11522182&linksrc=similar_articles_link&ordinalpos=3" data-ga-category="similar_article" data-ga-action="11522182" data-ga-label=""> HIV type 1 Tat inhibits tumor necrosis factor alpha-induced repression of tumor necrosis factor receptor p55 and amplifies tumor necrosis factor alpha activity in stably tat-transfected HeLa Cells. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Chiao C, Bader T, Stenger JE, Baldwin W, Brady J, Barrett JC.</span> <span class="docsum-authors short-authors">Chiao C, et al.</span> <span class="docsum-journal-citation full-journal-citation">AIDS Res Hum Retroviruses. 2001 Aug 10;17(12):1125-32. doi: 10.1089/088922201316912736.</span> <span class="docsum-journal-citation short-journal-citation">AIDS Res Hum Retroviruses. 2001.</span> <span class="citation-part">PMID: <span class="docsum-pmid">11522182</span></span> </div> </div> </li> <li class="full-docsum"> <div class="docsum-content" style="display:inline;"> <a class="docsum-title" href="/27053552/" ref="article_id=27053552&linksrc=similar_articles_link&ordinalpos=4" data-ga-category="similar_article" data-ga-action="27053552" data-ga-label=""> HIV-1 Tat Protein Activates both the MyD88 and TRIF Pathways To Induce Tumor Necrosis Factor Alpha and Interleukin-10 in Human Monocytes. </a> <div class="docsum-citation full-citation"> <span class="docsum-authors full-authors">Planès R, Ben Haij N, Leghmari K, Serrero M, BenMohamed L, Bahraoui E.</span> <span class="docsum-authors short-authors">Planès R, et al.</span> <span class="docsum-journal-citation full-journal-citation">J Virol. 2016 Jun 10;90(13):5886-5898. doi: 10.1128/JVI.00262-16.
