The development of nonviral, peptide-based constructs able to elicit protective in vivo CTL responses represents a major challenge in the design of future vaccines. We report the design of branched peptide delivery vehicles, termed loligomers, that facilitate the import, processing, and presentation of CTL epitopes onto nascent MHC class I molecules. These(More)
INTRODUCTION Interferon regulatory factor 1 (IRF1) is induced by HIV early in the infection process and serves two functions: transactivation of the HIV-1 genome and thus replication, and eliciting antiviral innate immune responses. We previously described three IRF1 polymorphisms that correlate with reduced IRF1 expression and reduced HIV susceptibility.(More)
Cells from women who are epidemiologically deemed resistant to HIV infection exhibit a 40-60% reduction in endogenous IRF-1 (interferon regulatory factor-1), an essential regulator of host antiviral immunity and the early HIV replication. This study examined the functional consequences of reducing endogenous IRF-1 on HIV-1 replication and immune response to(More)
Food allergies, and peanut allergy in particular, are leading causes of anaphylactic fatalities worldwide. The immune mechanisms that underlie food allergy remain ill-defined and controversial, in part because studies in humans typically focus on analysis of a limited number of prototypical Th1/Th2 cytokines. Here we determine the kinetics and prevalence of(More)
