Blocking virus infection with soluble cell receptors

We recently discussed the development of a soluble receptor for HIV-1 that provides broad and effective protection against infection of cells and of nonhuman primates. Twenty-five years ago my laboratory published a paper which concluded that using soluble receptors to block virus infection might not be a good idea. In the first paragraph of that paper we wrote: …it has …

Blocking HIV infection with two soluble receptors

Because viruses must bind to cell surface molecules to initiate replication, the use of soluble receptors to block virus infection has long been an attractive therapeutic option. Soluble receptors have been developed that block infection with rhinoviruses and HIV-1, but these have not been licensed due to their suboptimal potency. A newly designed soluble receptor …

Antimicrobial peptides induced by herpesvirus enhance HIV-1 infection

The risk of being infected with human immunodeficiency virus type 1 (HIV-1) is substantially enhanced in individuals with other sexually transmitted diseases. For example, infection with herpes simplex virus type 2 (HSV-2) increases the risk ratio of acquiring HIV from 2 to 4. Explanations for this increased risk include direct inoculation of HIV-1 into the …
