In this first functional comparison, we measured cell-associated (CA) short HIV-1 RNA transcripts, a marker of active transcription, alongside HIV-1 DNA in white blood cells from 92 virally suppressed individuals on INSTI-based (n = 73) or non-INSTI-based (n = 19) ART.

This gap is mainly due to challenges that researchers of this region are facing in initiating and advancing HIV cure research locally, with lesser commitment from the French-speaking countries. Furthermore, capacity-building of early career scientists on HIV cure research remains constrained due to limited awareness and language barriers to existing opportunities. Even though HIV non-B subtypes represent 89 % of circulating subtypes worldwide, cure research has been extensively focused on subtype B (prevalent in America and Europe). Interestingly, WCA (known as HIV pandemic epicentre with a broad genetic diversity) offers a unique landscape for cure research with a likelihood of generalisability across various HIV subtypes. This viewpoint discusses the importance of establishing an HIV Cure Academy for WCA to support scientists, policymakers and community stakeholders from French-speaking countries in contributing to the global efforts towards HIV cure.&lt;/div&gt;&lt;div&gt;Building on discussions, the establishment of an \"HIV Cure Academy\" emerges as a hallmark to: (i) raise awareness, (ii) build capacity, (iii) address scientific gaps, (iv) develop networks, and (v) foster advocacy and policy-briefing on integrating HIV cure research into national HIV agenda. The Academy is envisioned as a hub, facilitating relationships between community-based organizations, people living with HIV (PLHIV), research institutions and decision makers.
