Ficolin-2 binds to HIV-1 gp120 and blocks viral infection

Viral Dynamics in HIV-1 Infection

levels fall to lower steady-state values that vary in differA great deal of progress has been made in understandent individuals and that are predictive of the rate of ing the molecular biology of HIV-1 replication (see redisease progression (Mellors et al., 1996). In untreated views by Cullen [1998], Chan and Kim [1998], and Littasymptomatic patients, the plasma HIV-1 RNA levels man [1998] in t...

Viral Dynamics of Acute HIV-1 Infection

Viral dynamics were intensively investigated in eight patients with acute HIV infection to define the earliest rates of change in plasma HIV RNA before and after the start of antiretroviral therapy. We report the first estimates of the basic reproductive number (R(0)), the number of cells infected by the progeny of an infected cell during its lifetime when target cells are not depleted. The mea...

Cell surface-associated Tat modulates HIV-1 infection and spreading through a specific interaction with gp120 viral envelope protein.

Human immunodeficiency virus-1 (HIV-1) Tat, a nuclear transactivator of viral gene expression, has the unusual property of being released by infected cells. Recent studies suggest that extracellular Tat is partially sequestered by heparan sulfate proteoglycans. As a consequence, Tat is concentrated on the cell surface and protected from proteolytic degradation, thus remaining in a biologically ...

Identification and Characterization of a Broadly Cross-Reactive HIV-1 Human Monoclonal Antibody That Binds to Both gp120 and gp41

Identification of broadly cross-reactive HIV-1-neutralizing antibodies (bnAbs) may assist vaccine immunogen design. Here we report a novel human monoclonal antibody (mAb), designated m43, which co-targets the gp120 and gp41 subunits of the HIV-1 envelope glycoprotein (Env). M43 bound to recombinant gp140 s from various primary isolates, to membrane-associated Envs on transfected cells and HIV-1...
