Apoptosis in HIV infection
It is reported that DNA fragmentation (indicating apoptosis) is rarely observed in HIV-1 or SIV-producing infected cells, and HIV-1 or SIV RNA is rarely (0-1%) observed in apoptotic cells. What is the role of ...

Resistance to HIV–1 infection: It's in the genes
A genetic defect in the HIV-1 co-receptor provides resistance to infection.

Evolutionary pattern of human immunodeficiency virus (HIV) replication and distribution in lymph nodes following primary infection: Implications for antiviral therapy
Evolutionary patterns of virus replication and distribution in lymphoid tissue during the early phases of HIV infection have not been delineated. Lymph node (LN) biopsies were excised from patients at differen...

The Role of US Government Agencies in Vaccine Research And Development
Anthony Fauci and Gregory Folkers (National Institute of Allergy and Infectious Diseases) discusses the role of US government agencies and the NIAID in particular, in the fight against infectious diseases and ...

Effect of interleukin-2 on the pool of latently infected, resting CD4+ T cells in HIV-1-infected patients receiving highly active anti-retroviral therapy
The size of the pool of resting CD4+ T cells containing replication-competent HIV in the blood of patients receiving intermittent interleukin (IL)-2 plus highly active anti-retroviral therapy (HAART) was signific...

Relationship between pre-existing viral reservoirs and the re-emergence of plasma viremia after discontinuation of highly active anti-retroviral therapy
We examined the pathogenic significance of the latent viral reservoir in the resting CD4+ T cell compartment of HIV-1-infected individuals as well as its involvement in the rebound of plasma viremia after discont...

Protection of rhesus macaques against disease progression from pathogenic SHIV-89.6PD by vaccination with phage-displayed HIV-1 epitopes
The antigenic polymorphism of HIV-1 is a major obstacle in develo** an effective vaccine. Accordingly, we screened random peptide libraries (RPLs) displayed on phage with antibodies from HIV-infected individ...

Bioterrorism: A clear and present danger
The anthrax attacks in the United States, juxtaposed against the September 11 terrorist attacks on New York and Washington, DC, have transformed a theoretical threat to stark reality. The biomedical research c...

HIV and AIDS: 20 years of science
From the identification of HIV as the agent that causes AIDS, to the development of effective antiretroviral drugs, the scientific achievements in HIV research in the past 20 years have been formidable. Some o...

Induction of unnatural immunity: prospects for a broadly protective universal influenza vaccine
The immune system normally responds to influenza virus by making neutralizing antibodies to regions of the viral spike, the hemagglutinin, that vary year to year. This natural response protects against circula...

Targeting α4β7 integrin reduces mucosal transmission of simian immunodeficiency virus and protects gut-associated lymphoid tissue from infection
Aftab Ansari and his colleagues show that antibody-mediated masking of α4β7 integrin impedes intravaginal transmission of simian immunodeficiency virus in macaques.

Distinct mechanisms of long-term virologic control in two HIV-infected individuals after treatment interruption of anti-retroviral therapy
Certain infected individuals suppress human immunodeficiency virus (HIV) in the absence of anti-retroviral therapy (ART). Elucidating the underlying mechanism(s) is of high interest. Here we present two contra...

A multiclade env–gag VLP mRNA vaccine elicits tier-2 HIV-1-neutralizing antibodies and reduces the risk of heterologous SHIV infection in macaques
The development of a protective vaccine remains a top priority for the control of the HIV/AIDS pandemic. Here, we show that a messenger RNA (mRNA) vaccine co-expressing membrane-anchored HIV-1 envelope (Env) a...
