44 – The Central Nervous System Reservoir: Impact for Cure and Ongoing Neuropathology

HIV persists in the central nervous system (CNS), and a subset of PWH develop neurocognitive issues despite virally suppression. With a diverse set of infected cells comprising the CNS reservoir, along with the impact of both acute and chronic infection on local inflammation and blood brain barrier integrity, the CNS presents an important and unique…

37 – Post-Tuberculosis Disease: Opening Pandora’s Box

This talk will highlight the burden and spectrum of post-tuberculosis disease, focusing on the complexities of clinical presentation and pitfalls in assessment. We will give an overview of pathogenesis, and an update of recent work in post-tuberculosis lung disease (PTLD). We will highlight important knowledge gaps in the field, and will discuss ongoing work and…

48 – Long-Acting InSTI Strategies: Understanding the Risks for Failure and Resistance

Long-acting injectables (LAI) represents one of the most significant advances in antiretroviral therapy in recent years, offering durable suppression for PLWH who find daily oral medications challenging. Confirmed virological failure (CVF) is a low-incidence (1.4% over 152 weeks) but high-consequence event, with almost all developing drug-resistant mutations. This is in contrast to daily oral INSTI-based…

26 – Innovations in HIV Service Delivery: Building a Path Forward with Those Left Behind

Over the last 40 years, remarkable achievements have been recorded in the HIV response, with service delivery models that have increased access to HIV testing, expansion of the HIV prevention toolbox, availability of newer and less toxic antiretroviral therapy resulting in fewer people acquiring HIV in 2023 than at any point since the late 1980’s…

20 – Immune Responses During Viral Rebound

The objectives of this talk are to: (1) define different patterns of HIV rebound (i.e., categories of post-ART control), (2) review examples of effective immune responses against HIV, focusing on immune mechanisms that have been implicated in post-ART control, and (3) discuss lessons learned about immune responses to rebound from recent ATI trials, including the…

21 – Advanced HIV Disease in Children

In 2025, late diagnosis of HIV in children continues to be a significant global concern, with many presenting with advanced HIV disease (AHD). This issue contributes to a considerable number of hospital admissions, particularly among infants, due to acute conditions such as pneumonia, sepsis, and diarrhea. These acute illnesses are frequently accompanied by important by…

32 – The Landscape of Proviral Integration in the HIV-1 Reservoir and Its Relationship to Latency and Reactivation

HIV-1 persists in a mostly latent state within blood and tissues during suppressive ART. Proviral integration sites may play a critical role in the establishment and maintenance of this latent reservoir. Understanding the landscape of proviral integration is essential for deciphering the mechanisms behind HIV-1 latency and reactivation. Recent studies have shed light on the…

35 – Influence of Hormone Changes on Physiology, Virology, and Immunology

Disentangling the unique impacts of aging and reproductive aging through menopause may identify novel features of the pathogenesis of HIV that will inform strategies to manage longterm complications and achieve an HIV cure.  Early data indicate that menopause and declining levels of estradiol are associated with increased inflammation and changes in HIV viral dynamics.  Further…

36 – Long-Acting Treatments for Tuberculosis

Long-acting injectable formulations are revolutionizing HIV treatment and prevention and have similar potential to improve the treatment and prevention of tuberculosis, including simpler, shorter regimens and expanded treatment options. This presentation will describe how long-acting injectable formulations could address important obstacles to ending the world’s oldest pandemic, review recent progress in the development of long-acting…

40 – Long-Acting Preexposure Prophylaxis: Why Can’t We Get to Scale?

In the past 12 years, 6.2 million individuals globally have been prescribed PrEP since its initial approval by the US FDA. The majority of these prescriptions, 1.4 million, have been issued in the past two years. However, oral PrEP’s effectiveness is contingent on high adherence, posing challenges for certain high-risk groups. Research indicates that long-acting…
