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}

HIV-positive individuals have a 30-fold higher risk of contracting TB compared to non-HIV individuals. Assessment of HIV-TB disease progression commonly relies on measuring CD4 cell counts. However, in areas with limited access, the World Health Organization (WHO) recommends using Total Lymphocyte Count (TLC) ≤ 1200 cells/μL as an alternative.

However, the success of ART crucially depends on patient adherence to complex medication regimens that come with the therapy. Patients must meticulously adhere to their prescribed treatment plans to maintain viral suppression and prevent the progression of HIV. Medication adherence, a multifaceted challenge in healthcare, becomes particularly entangled within the realm of ART. Patients are often prescribed a combination of antiretroviral medications, each with unique dosing schedules and dietary requirements as instructed by the physician. For individuals with varying levels of health literacy, language proficiency, and cultural backgrounds, comprehending and adhering to these regimens can be overwhelming and challenging. Non-adherence to these medications can result in treatment failure, drug resistance, and compromised health outcomes that burden the healthcare systems. In that perspective, the role of pictograms as visual aids emerges as part and parcel of patient education and counseling within healthcare systems. Pictograms are graphical representations of concepts or actions designed to transcend linguistic and literacy barriers. When used in conjunction with ART, they simplify complex medication instructions, empower patients with knowledge, and improve adherence. Generally, the role of pictograms in supporting medication adherence and patient counseling in antiretroviral therapy is a powerful testament that serves a purpose in bridging communication and literacy gaps within the healthcare systems.
