Factors associated with satisfaction with community-based non-medicalized counseling and testing using HIV rapid tests among MSM in France.

The aims of the study were to determine the level of satisfaction of men who have sex with men (MSM) participating in two community-based non-medicalized counseling and testing programs (ANRS-DRAG and ANRS-COM'TEST) offering HIV rapid tests (hereafter CBOffer), and to identify factors associated with satisfaction. Between 2009 and 2011, 436 participants voluntarily benefited from a CBOffer in the two programs. They completed self-administered questionnaires before and after testing.

The 1.2-megabase genome sequence of Mimivirus.

We recently reported the discovery and preliminary characterization of Mimivirus, the largest known virus, with a 400-nanometer particle size comparable to mycoplasma. Mimivirus is a double-stranded DNA virus growing in amoebae. We now present its 1,181,404-base pair genome sequence, consisting of 1262 putative open reading frames, 10% of which exhibit a similarity to proteins of known functions.

HIV-1 gag polyprotein rescues HLA-DR intracellular transport in a human CD4+ cell line.

Major histocompatibility complex class II HLA-DR molecules are plasma-membrane integral heterodimers, constitutively expressed in antigen-presenting cells. Their expression is known to be upregulated in peripheral T lymphocytes upon cell activation and to be constitutive in T cell lines. In H78-C10.

Viral and cellular specificities of caprine arthritis encephalitis virus Vif protein.

The caprine arthritis encephalitis virus (CAEV) Vif protein is necessary for a productive infection of susceptible goat cells. The vif gene is conserved among all primate and most nonprimate lentiviruses. However, previous reports demonstrated that, in their respective host cells, primate Vif deleted lentiviruses could not be complemented by nonprimate Vif proteins, suggesting that species-specific restrictions between Vif and the virus-producing cells may modulate the Vif function on viral infectivity.

Caprine arthritis encephalitis virus: evidence for a B/D-type assembly pathway in a C-type lentivirus replication.

Lentiviruses, among which is caprine arthritis encephalitis virus (CAEV), are known to concomitantly assemble and bud at the plasma membrane of infected cells, in a C-type defined pathway. Electron microscopy analysis of CAEV-infected cells demonstrated viral particles budding at the plasma membrane and into intracellular membrane-surrounded vesicles. Furthermore, nonenveloped immature virus-like particles, resembling intracytoplasmic type-A particles (ICAPs), accumulated within the cytoplasm of those cells.
