CD4 T follicular helper cells (Tfh) are essential for establishing serological memory and have distinct helper attributes that impact both the quantity and quality of the antibody response. Insights into Tfh subsets that promote antibody persistence and functional capacity can critically inform vaccine design. Based on the Tfh profiles evoked by the live attenuated measles virus vaccine, renowned for its ability to establish durable humoral immunity, we investigated the potential of a Tfh1/17 recall response during the boost phase to enhance persistence of HIV-1 Envelope (Env) antibodies in rhesus macaques. Using a DNA-prime encoding gp160 antigen and Tfh polarizing cytokines (interferon protein-10 (IP-10) and interleukin-6 (IL-6)), followed by a gp140 protein boost formulated in a cationic liposome-based adjuvant (CAF01), we successfully generated germinal center (GC) Tfh1/17 cells. In contrast, a similar DNA-prime (including IP-10) followed by gp140 formulated with monophosphoryl lipid A (MPLA) +QS-21 adjuvant predominantly induced GC Tfh1 cells. While the generation of GC Tfh1/17 cells with CAF01 and GC Tfh1 cells with MPLA +QS-21 induced comparable peak Env antibodies, the latter group demonstrated significantly greater antibody concentrations at week 8 after final immunization which persisted up to 30 weeks (gp140 IgG ng/ml- MPLA; 5500; CAF01, 2155; p

While human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS) researchers have made remarkable strides in the treatment, management, and prevention of HIV/AIDS, one area of research related to HIV/AIDS remains woefully underrepresented in the scientific literature: suicide prevention. The risk of death by suicide among people living with HIV/AIDS (PLWHA) is 100 times higher compared with that among the general population, and the lifetime prevalence of suicide attempts is similarly elevated. Though there have been many suicide prevention studies worldwide and effective interventions have been identified, few prevention strategies have been tested and implemented among PLWHA. A preliminary review of articles published since 2018 revealed only two behavioral interventions designed to address suicide risk in PLWHA, neither of which were based in the United States. No systematic reviews of behavioral interventions for suicide prevention among PLWHA have been published. In this commentary, we call for research to evaluate the effectiveness of suicide prevention interventions and policies that could decrease suicide rates among PLWHA. [ABSTRACT FROM AUTHOR]

The Counter Narrative Project (CNP) was founded to shift narratives and shatter stereotypes about Black gay, bisexual, and queer men to advance social justice. This paper describes three programs CNP implemented that were organized around collective memory as a strategy to respond to collective trauma experienced by this community. [ABSTRACT FROM AUTHOR]

Young Black gay/bisexual and other men who have sex with men (YB-GBMSM) are disproportionately impacted by HIV/AIDS. Novel intervention strategies are needed to optimize engagement in HIV care for this population. We sought to develop a group-level intervention to enhance resilience by augmenting social capital (defined as the sum of resources in an individual's social network) among YB-GBMSM living with HIV, with the ultimate goal of improving engagement in HIV care. Our multiphase, community-based participatory research (CBPR) intervention development process included: (1) Development and maintenance of a youth advisory board (YAB) comprised of YB-GBMSM living with HIV; (2) Qualitative in-depth interviews with YB-GBMSM living with HIV; (3) Qualitative in-depth interviews with care and service providers at clinics and community-based organizations; and (4) Collaborative development of intervention modules and activities with our YAB, informed by social capital theory and our formative research results. The result of this process is Brothers Building Brothers By Breaking Barriers, a two-day, 10-module group-level intervention. The intervention does not focus exclusively on HIV, but rather takes a holistic approach to supporting youth and enhancing resilience. Intervention modules aim to develop resilience at the individual level (exploration of black gay identity, development of critical self-reflection and coping skills), social network level (exploring strategies for navigating family and intimate relationships) and community level (developing strategies for navigating clinical spaces and plans for community participation). Most intervention activities are interactive, in order to facilitate new social network connections - and accompanying social capital - within intervention groups. In summary, our intensive CBPR approach resulted in a novel, culturally-specific intervention designed to enhance HIV care engagement by augmenting resilience and social capital among YB-GBMSM living with HIV.

The Internet is a popular way for people to meet casual sex partners. However, online outreach remains largely unexplored to promote voluntary counseling and testing for HIV. The Student Health Action Coalition’s HIV testing program (SHAC-HIV) targets high-risk clients through tailored Internet outreach via chat rooms, social networking sites, and online forums. The SHAC-HIV model also demonstrates that nontraditional testing sites can provide low-cost, client-centered, high-quality services to support increased demand for HIV-testing services. Within the clinic, SHAC-HIV’s testing model includes four major components: (a) reliance on a team of well-trained health sciences student volunteers; (b) rapid oral-fluid HIV tests; (c) universal, consent-based testing with client-centered health education and counseling; and (d) coordinated referrals for follow-up testing, treatment, and care. This approach reaches high-risk clients as well as undiagnosed infections. In 2007, there were nine confirmed positive results out of 389 tests, yielding a 2.3% positivity rate. This positivity percentage is higher than any other nontraditional testing site in North Carolina. This article describes the SHAC-HIV outreach and vo-luntary counseling and testing program with the aim of encouraging adoption of the model by other nontraditional testing sites.
