Port, we show that soluble mimics of CD4 inhibit HIV-1 infection by prematurely triggering the viral envelope glycoproteins. The unstable activated state of the virus lasts only a few minutes, after which the virus loses the ability to infect cells. This novel strategy for inhibition may be generally applicable to other viruses besides HIV-1, some of which are also activated by binding to their re

Coproteins [1]. Binding of gp120 to the receptor, CD4, on the target cell surface induces major conformational changes in the envelope glycoproteins [2]. These changes allow gp120 to bind the viral coreceptor, either CXCR4 or CCR5 [3?]. CD4 binding also induces the formation of a gp41 pre-hairpin intermediate, in which three hydrophobic grooves on the surface of a coiled coil formed by the heptad

Espite successful HCV eradication. Other complications such as development of carcinoma may be more readily amenable to more rapid risk reduction with antiviral therapy. Further studies with long periods of follow-up will be needed to address these questions. Our study has several limitations. Not all patients had measures of immune activation documented in their study records and were therefore e

Amic changes in conformation and function of the HIV-1 envelope glycoproteins, immediately after engagement of the activating molecules. Using these tools, we found that SCMs inactivate envelope glycoprotein function by an activation-triggered inhibition process, through induction of a metastable activated state.Materials and Methods Reagents and AntibodiesFour-domain sCD4 (molecular weight 50 kDa

Es would most likely not have been affected. The measures of immune activation were not assessed at enrollment into the study cohort, and we therefore cannot make temporal inferences of a causal nature nor could we control for them in the multivariable Cox models. We used prevalence rate ratios (PRRs) to estimate the associations of interest as risk was our parameter of interest. We chose PRRs as
