To explore the human T cell response to acute viral infection, we performed a longitudinal analysis of CD8 + T cells responding to the live yellow fever virus and smallpox vaccines—two highly successful human vaccines. Our results show that both vaccines generated a brisk primary effector CD8 + T cell response of substantial magnitude that could be readily quantitated with a simple...
The purpose of this exploratory study was to examine personal characteristics, socio-environmental conditions, and motivational factors that potentially influence HIV vaccine research community engagement. Specifically, the study identified predictive aspects that may aid in future community program development on HIV vaccine issues. A cross-sectional survey consisting of evaluative measures, demographics,...
Thirty-three HIV-seronegative adults were recruited into a Phase I safety and immunogenicity HIV-1 vaccine trial. The immunogens were as follows: a synthetic, monovalent, octameric HIV-1 MN V3 peptide in aluminum hydroxide (alum) adjuvant administered by intramuscular delivery; and a similar product encapsulated in biodegradable micro-spheres composed of co-polymers of lactic and glycolic acids, administered...
Three separate studies were undertaken in HIV-1 uninfected persons to determine if the adjuvant QS-21 improves the magnitude or kinetics of immune responses induced by recombinant soluble gp120 HIV-1 MN protein (rsgp120) immunization. The QS-21 was administered at two doses (50 and 100 μg), either alone or in combination with aluminum hydroxide (600 μg). At the highest doses of rsgp120...
The matrix (MA) proteins of human immunodeficiency virus type 1 (HIV-1) and simian immunodeficiency virus (SIV) are known to be important for the targeting and assembly of lentiviral proteins. The objective of the present study was to determine whether the MA protein of HIV-1 was sufficient for particle assembly and release. Eukaryotic expression of wild-type HIV-1 Gag-Pol, HIV-1 MA alone, or SIV...
