Web24 Oct 2013 · Immunization of rhesus macaques against Gag of SIV resulted in a more rapid appearance of Env antibodies after infection with SIV or SHIV challenge viruses although the vaccines lacked an Env component. We therefore explored whether T helper cells specific for internal HIV proteins could provide intrastructural help for Env-specific B cells and thus … Web27 Apr 2016 · An intrarectal challenge SHIV AD8-EO inoculum size of ten TCID 50 was chosen for repeated low-dose experiments on the basis of previous results indicating that (1) 1,000 TCID 50 of SHIV AD8-EO ...

WebVaccine-induced immunity to HIV is a major research focus, but relevant correlates of protection remain controversial. Here, Pauthner et al. study protection from hard-to-neutralize SHIVBG505 challenge after immunization with native-like BG505 Envelope trimers in nonhuman primates and identify neutralizing antibodies, but not T cell or ADCC activity, … WebAbstract. Developing an immunogen that elicits broadly neutralizing antibodies (bNAbs) is an elusive but important goal of HIV vaccine research, especially after the recent failure of the leading T cell based HIV vaccine in human efficacy trials.
WebSubsequent challenge with the SHIV BG505 (a simian/human immunodeficiency virus (SHIV) construct expressing surface HIV BG505 trimers and exhibiting neutralization resistance characteristic of circulating HIV (a so-called tier 2 virus)) showed a tight correlation between serum neutralization titres at the time of challenge and protection … Web1 Jan 2011 · To guide vaccine design, we assessed whether human monoclonal antibodies (MAbs) b12 and b6 against the CD4 binding site (CD4bs) on HIV-1 gp120 and F240 against an immundominant epitope on gp41...
