Orchestrated trafficking and activation by pathogen-derived peptides define the ability of CD4 T helper cells to contribute to an effective adaptive immunity. In this issue of The EMBO Journal, Martín-Leal et al show that the inflammatory chemokine receptor CCR5, well known for its role in cell migration and HIV infection, regulates ceramide synthesis and TCR nanoclustering to promote memory CD4 T cell activation.

Background: Assisted partner services (APSs; sometimes called index testing) are now being brought to scale as a high-yield HIV testing strategy in many nations. However, the success of APSs is often hampered by low levels of partner elicitation. The Computer-Assisted Self-Interview (CASI)-Plus study sought to develop and test a mobile health (mHealth) tool to increase the elicitation of sexual and needle-sharing partners among persons with newly diagnosed HIV.

Background: Indonesia's vast archipelago and substantial population size present unique challenges in addressing its multifaceted HIV epidemic, with 90% of its 514 districts and cities reporting cases. Identifying key populations (KPs) is essential for effectively targeting interventions and allocating resources to address the changing dynamics of the epidemic.
Objective: We examine the 2022 mapping of Indonesia's KPs to develop improved HIV and AIDS interventions.

Pre-exposure prophylaxis (PrEP) has proven to be a powerful tool in preventing HIV infection. There is limited information about the factors associated with willingness to use different PrEP modalities among adolescent girls and young women (AGYW) in Africa. We assessed willingness to use long-acting injectable PrEP (LAI-PrEP) among 14-24-year-old AGYW at high risk of HIV in Uganda, and associated factors determined using multivariable complementary log-log regression.
