Broadly neutralizing antibodies (bNAbs), capable of targeting conserved Env epitopes, offer a promising path for vaccine design. Germline-targeting (GT) strat-egies have emerged as a promising approach to engage naive B cell precursors that have the po-tential to mature into bNAb-producing cells. Advances in GT have enabled the design of immu-nogens capable of recruiting specific bNAb precursors in animal models and early clinical trials. Despite these successes, achieving neutralization breadth requires sequential immunizations with tailored boosting strategies to guide B cell maturation. Studies underscore the importance of using immunogens that mimic native Env structures while modulating glycosylation patterns to focus immune responses. Emerging approaches, such as membrane-bound presentation and mRNA de-livery, hold the potential for enhancing immunogen effectiveness and rapid pre-clinical and in human screening to identify combinations of immunogens that foster bNAb lineages. This review seeks to synthesize key developments in GT strategies for HIV-1 vaccines, highlighting the de-sign and implementation of immunogens that drive bNAb precursor maturation.

Double-negative T cells (DNT) can compensate for immunity and prevent immune overactivation in HIV patients. Also, immune non-responders (INRs) have fewer DNT cells than immune responders (IRs). HIV infection and ART can change the dynamic function of cell mitochondria, which are crucial in ferroptosis. Ferroptosis is a form of cell death marked by the accumulation of reactive oxygen species (ROS) and iron-dependent lipid peroxidation. Yet, the changes in DNT cell function in INRs and the impact of ferroptosis on immune reconstitution remain unclear.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Aims: &lt;/strong&gt;Our study focused on the expression level of DNT cells in HIV immune non-responders. Then, we detected markers of ferroptosis, cell activation, proliferation, killing function, and inflammatory states of DNT cells in INRs.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The study involved 88 PLHIVs who had received antiretroviral therapy for over 4 years and tested virus-negative. These patients were classified into two groups: 28 INRs (CD4 &lt; 350/μl) and 60 IRs (CD4 ≥350/μl). Additionally, 25 sex- and age-matched HCs were included. Flow cytometry was used to detect ferroptosis markers (JC-1, Lipid ROS, lipid peroxidation), cell proliferation, and cell activation. Transmission electron microscopy (TEM) was applied to observe mitochondrial morphology. Finally, statistical analysis was performed on the detection results.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;After long-term antiretroviral therapy, we found that INRs had a lower DNT cell count than IRs. Regarding proliferation and activation, our results showed higher CD38/HLA-DR co-expression and Ki67 expression in INRs' DNT cells than in IRs', indicating over-activation of DNT cells in INRs. In terms of killing function, the perforin and granzyme B levels in INRs' DNT cells were lower than those in IRs', suggesting impaired killing function of DNT cells in INRs. For ferroptosis, the proportion of DNT cells with decreased MMP in INRs was higher than in IRs and HCs. INRs' DNT cells also had higher levels of lipid ROS and lipid peroxidation compared to those in IRs and HCs. TEM revealed that the mitochondria of INRs' DNT cells had typical morphological features. Moreover, INRs' DNT cells had a greater degree of inflammation.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;Our study centered on the proliferation, activation, ferroptosis, killing function, and inflammatory status of DNT cells in INRs. We found that DNT cells in INRs had more active proliferation and activation, weakened killing function, mitochondrial function with typical ferroptosis features, and increased TNF-αlevels.

Such antibodies recognize regions of the viral envelope glyco-protein (Env) that are conserved among the diverse HIV-1 clades and strains. They are isolated from people living with HIV-1 to protect animals from experimental viral exposure and reduce HIV-1 acquisition in clinical settings. However, despite efforts spanning several decades, bNAbs have not been elicited through immunization. The HIV Env efficiently binds bNAbs, but not their unmutated (germline, gl) precursors. In contrast, Env readily engages the germline precursors of antibodies with no, or very narrow, cross-neutralizing activities (non-neutralizing antibodies, nnAbs). That, in part, explains why Env-based immunogens consistently elicit nnAbs, but not bNAbs. In the past decade, Env-derived proteins have been specifically designed to engage the germline precursors of diverse bNAbs. These 'germline-targeting' Env immunogens activate the corresponding naive B cells in vivo, but are unable to guide their proper maturation towards their broadly neutralizing forms. For this, immunizations with currently not well-defined heterologous Envs are required. Here, we discuss the development of germline-targeting Env immunogens, their in vivo evaluation, and the strategies currently under evaluation that aim to rapidly guide the mat-uration of germline-precursor BCRs into their broadly neutralizing forms.</p>","PeriodicalId":10911,"journal":{"name":"Current HIV Research","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143482477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
