The National Institute of Allergy and Infectious Diseases (NIAID) awarded a $1,233,520 Project Grant under the Allergy and Infectious Diseases Research program (CFDA 93.855) to The Johns Hopkins University to improve HIV prevention among transgender women (TGW) and gender diverse persons. The key objectives are to: A) Evaluate multi-compartment pharmacokinetics of long-acting cabotegravir (CAB-LA) for pre-exposure prophylaxis (PrEP) in cisgender and TGW/gender diverse persons on estrogen-based...
This Project Grant award from the National Institute of Allergy and Infectious Diseases (NIAID) under the Allergy and Infectious Diseases Research program (CFDA 93.855) provides $534,242 to the New York Blood Center, Inc. to study the immune and behavioral responses of transgender women to the updated seasonal COVID-19 vaccines. The study aims to understand the impact of gender-affirming hormone therapy on immune responses and factors influencing vaccine uptake in this population. The award will...
This federal Project Grant award from the National Institute of Allergy and Infectious Diseases (NIAID), under the Allergy and Infectious Diseases Research program (CFDA 93.855), provides $205,603 to Oregon Health & Science University (OHSU) to study the impact of estrogen replacement therapy on bone health in an aging population of women living with HIV. The research aims to measure the effect of antiretroviral therapy (ART) and menopause, both with and without hormone replacement...
This $1,260,020 Project Grant award from the National Institute of Allergy and Infectious Diseases (NIAID) under the Allergy and Infectious Diseases Research program (CFDA 93.855) will support a 3-year pilot study to assess the acceptability, feasibility, appropriateness, and preliminary effects of integrating an evidence-based mental health intervention for transgender and gender diverse (TGD) individuals affected by violence and HIV in Los Angeles County. The research team will leverage an...
This federal Project Grant award, provided by the National Institute of Allergy and Infectious Diseases (NIAID) under the Allergy and Infectious Diseases Research program (CFDA 93.855), aims to conduct a longitudinal analysis of the HIV reservoir and type I/III interferon system in individuals who initiated antiretroviral therapy (ART) during primary HIV infection. The total funding for this grant is $1,041,598, with an award date of June 1, 2024 and an ultimate completion date of April 30,...
This Project Grant award of $149,528 from the National Institute of Allergy and Infectious Diseases (NIAID) under the Allergy and Infectious Diseases Research program (CFDA 93.855) will support research to investigate the mechanisms behind sex differences in vaccine-induced immunity. The research, to be conducted by The Johns Hopkins University, will examine how estrogen receptor signaling and metabolic activation of the mTOR pathway in B cells contribute to greater antibody responses...
This federal Project Grant award from the National Institute of Allergy and Infectious Diseases (NIAID), under the Allergy and Infectious Diseases Research program (CFDA 93.855), aims to inform and test a future behavioral economic-based intervention to support pre-exposure prophylaxis (PrEP) engagement among transgender women in the Philippines. The $1,013,248 award will fund two key activities: 1) qualitative exploration and identification of preferred PrEP attributes and features through...
This federal Project Grant award from the National Institutes of Health (NIH) Allergy and Infectious Diseases Research program (CFDA 93.855) supports research to investigate the role of chromosomal aberrations, specifically the loss of the Y chromosome (LOY), in driving HIV-1 latency and reactivation resistance. The $424,254 award, with an end date of July 31, 2024, will enable the University of Alabama at Birmingham (UAB) to extend their previous studies on the correlation between LOY and the...
This Federal Project Grant award of $234,115 from the National Institute of Allergy and Infectious Diseases (NIAID), under the Allergy and Infectious Diseases Research program (CFDA 93.855), supports research to characterize the HIV latent reservoir and understand the mechanisms driving infected cell proliferation. The key objectives are to: 1) fully characterize the clonality distribution of intact and defective HIV proviruses in people living with HIV on antiretroviral therapy, and 2)...
This federal Project Grant award, provided by the National Institute of Allergy and Infectious Diseases (NIAID) under the Allergy and Infectious Diseases Research program (CFDA 93.855), aims to advance understanding of host-viral dynamics and potential therapeutic strategies for HIV eradication. The $794,045 award supports research at the University of California, San Francisco (UCSF) to investigate the role of class II cytokines, such as IL-10 and interferons, in controlling HIV across...

This federal Project Grant award from the National Institute of Allergy and Infectious Diseases (NIAID), under the Allergy and Infectious Diseases Research program (CFDA 93.855), provides $1,542,980.00 to support research on the impact of gender-affirming hormone therapy on HIV viral dynamics and immune responses in transgender women.

The research project aims to explore three key areas: 1) the effect of estradiol therapy on measures of the HIV reservoir, including size, activity, intactness, integration site, and clonality; 2) the impact of HIV and hormone therapy on immune cell profiles and inflammatory biomarkers; and 3) the effect of hormone therapy on metabolic features in the plasma proteome and cellular energy dependence. This work will leverage two unique cohorts of transgender women, including an existing cross-sectional cohort and participants from a clinical trial initiating estrogen therapy, to comprehensively assess the interplay between gender-affirming hormone use, HIV infection, and immunological/virological outcomes.

The project is being led by The Johns Hopkins University, with a sub-award to the University of California, San Diego, and is scheduled for completion by March 2025.
