An infant born to a woman with human immunodeficiency virus type 1 (HIV-1) infection began receiving antiretroviral therapy (ART) 30 hours after birth owing to high-risk exposure. ART was continued when detection of HIV-1 DNA and RNA on repeat testing met the standard diagnostic criteria for infection. After therapy was discontinued (when the child was 18 months of age), levels of plasma HIV-1 RNA, proviral DNA in peripheral-blood mononuclear cells, and HIV-1 antibodies, as assessed by means of clinical assays, remained undetectable in the child through 30 months of age. This case suggests that very early ART in infants may alter the establishment and long-term persistence of HIV-1 infection.

Human immunodeficiency virus-1 (HIV-1) uses a number of strategies to modulate viral and host gene expression during its life cycle. To characterize the transcriptional and translational landscape of HIV-1 infected cells, we used a combination of ribosome profiling, disome sequencing and RNA sequencing. We show that HIV-1 messenger RNAs are efficiently translated at all stages of infection, despite evidence for a substantial decrease in the translational efficiency of host genes that are implicated in host cell translation.

User adherence contributes to the effectiveness of topical pre-exposure prophylactic products designed to protect against human immunodeficiency virus type 1 (HIV-1) infection. Long-acting approaches that do not require daily or coitally-dependent use could potentially improve user adherence. This study aims to develop a long-acting vaginal film to deliver an integrase inhibitor, MK-2048, for prevention of HIV-1 infection.

Background: HIV infection has been associated with an increased risk of cancer development and Kaposi's sarcoma, non-Hodgkin's lymphoma, and invasive cervical cancers have been a manifestation of AIDS. With the advent of antiretroviral therapy, a collateral appearance of non-AIDS defining cancers (NADC) has been observed in HIV positive patients.
Methods: From January 1997 to December 2022, we performed an observational cross-sectional study, involving HIV-infected outpatients with both AIDS-defining cancers (ADC) and NADC, followed up in a tertiary hospital in Italy.

Sub-Saharan Africa accounts for almost 70 % of people living with HIV (PLWH) worldwide, with the greatest numbers centred in South Africa where 98 % of infections are caused by subtype C (HIV-1C). However, HIV-1 subtype B (HIV-1B), prevalent in Europe and North America, has been the focus of most cure research and testing despite making up only 12 % of HIV-1 infections globally. Development of latency models for non-subtype B viruses is a necessary step to address this disproportionate focus.

Background: Although antiretroviral therapy (ART) effectively inhibits viral replication, it does not fully mitigate the immunosenescence instigated by HIV infection. Cellular metabolism regulates cellular differentiation, survival, and senescence. Serine hydroxymethyltransferase 2 (SHMT2) is the first key enzyme for the entry of serine into the mitochondria from the de novo synthesis pathway that orchestrates its conversion glutathione (GSH), a key molecule in neutralising ROS and ensuring the stability of the immune system.
