Abstract
The human immunodeficiency virus (HIV) persists in latently infected CD4+T cells and integrates with the host genome until cell death. Acquired immunodeficiency syndrome (AIDS) is associated with HIV-1. Possibly, treating HIV/AIDS is an essential but challenging clinical goal. This review provides a detailed account of the types and mechanisms of monotherapy and combination therapy against HIV-1 and describes nanoparticle and hydrogel delivery systems. In particular, the recently developed capsid inhibitor (Lenacapavir) and the Ainuovirine/tenofovir disoproxil fumarate/lamivudine combination (ACC008) are described. It is interestingly to note that the lack of the multipass transmembrane proteins serine incorporator 3 (SERINC3) and the multipass transmembrane proteins serine incorporator 5 (SERINC5) may be one of the reasons for the enhanced infectivity of HIV-1. This discovery of SERINC3 and SERINC5 provides new ideas for HIV-1 medication development. Therefore, we believe that in treating AIDS, antiviral medications should be rationally selected for pre-exposure and post-exposure prophylaxis to avoid the emergence of drug resistance. Attention should be paid to the research and development of new drugs to predict HIV mutations as accurately as possible and to develop immune antibodies to provide multiple guarantees for the cure of AIDS.

Couroux P, Grosse N, Salapatek AM, Goyal Y, Pfaar O, Hohenfeld IP. Barrier-forming, drug-free nasal spray reduces allergic symptoms induced by house dust mite allergen. Clin Transl Allergy 2023; 13:e12277. [PMID: 37488728 PMCID: PMC10345461 DOI: 10.1002/clt2.12277] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2023] [Revised: 06/12/2023] [Accepted: 06/22/2023] [Indexed: 07/26/2023] Open
Abstract
BACKGROUND House Dust Mite (HDM) is the most common indoor allergen triggering allergic symptoms. First-line pharmacotherapy treatment is recommended in international guidelines, while the avoidance of allergens represents a still unmet guideline principle. AM-301 is a new non-pharmacological nasal spray that creates a protective gel-like barrier on the nasal mucosa, preventing the contact with the allergens. METHODS This randomized, open-label, 3-period crossover study assessed the efficacy and safety of AM-301. The objective was to determine whether AM-301 reduces allergic rhinitis (AR) symptoms in patients exposed to HDM allergens. Adults with confirmed Perennial Allergic Rhinitis (PAR; n = 37) were exposed to HDM allergen in a controlled Allergen Exposure Chamber before and during a treatment course of AM-301 (in six different sequences) within 3 weeks (A: One spray AM-301 per nostril/B: Two sprays AM-301 per nostril/C: no treatment). For the primary efficacy analysis, data from the total nasal symptom score (TNSS) were pooled from treatment A + B (D) and analyzed with Analysis of Covariance Model. As secondary endpoints, single time points, visits and symptoms were analyzed. RESULTS The primary endpoint (overall change in TNSS from baseline over all three visits) showed significant results (p = 0.0085). A comparable alleviation of all four symptoms (itchy nose, nasal congestion, runny nose, sneezing) by the protective layer started to emerge after 40 min and lasted up to 180 min (end of challenge). AM-301 resulted to be safe and well-tolerated. CONCLUSION AM-301 significantly reduced HDM-related allergic symptoms in a standardized allergen challenge. Protection was observed to last up to 180 min.

Abstract
In spite of the rollout of oral pre-exposure prophylaxis (PrEP), the rate of new HIV infections remains a major health crisis. In the United States, new infections occur predominantly in men having sex with men (MSM) in rural settings where access to PrEP can be limited. As an alternative congruent with MSM sexual behavior, we have optimized and tested tenofovir (TFV) and analog-based iso-osmolar and hypo-osmolar (HOsm) rectal douches for efficacy against rectal simian/human immunodeficiency virus (SHIV) infection of macaques. Single TFV HOsm high-dose douches achieved peak plasma TFV levels similar to daily oral PrEP, while other formulations yielded lower concentrations. Rectal tissue TFV-diphosphate (TFV-DP) concentrations at the portal of virus entry, however, were markedly higher after HOsm douching than daily oral PrEP. Repeated douches led to significantly higher plasma TFV and higher TFV-DP concentrations in rectal tissue at 24 hours compared with single douches, without detectable mucosal or systemic toxicity. Using stringent repeated intrarectal SHIV exposures, single HOsm high-dose douches delivered greater protection from virus acquisition for more than 24 hours compared with oral PrEP. Our results demonstrate a rapid delivery of protective TFV doses to the rectal portal of virus entry as a potential low-cost and safe PrEP alternative.

The ex vivo pharmacology of HIV-1 antiretrovirals differs between macaques and humans. iScience 2022; 25:104409. [PMID: 35663021 PMCID: PMC9157191 DOI: 10.1016/j.isci.2022.104409] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Revised: 04/12/2022] [Accepted: 05/11/2022] [Indexed: 01/08/2023] Open
Abstract
Non-human primates (NHP) are widely used for the pre-clinical assessment of antiretrovirals (ARVs) for HIV treatment and prevention. However, the utility of these models is questionable given the differences in ARV pharmacology between humans and macaques. Here, we report a model based on ex vivo ARV exposure and the challenge of mucosal tissue explants to define pharmacological differences between NHPs and humans. For colorectal and cervicovaginal explants in both species, high concentrations of tenofovir (TFV) and maraviroc were predictive of anti-viral efficacy. However, their combinations resulted in increased inhibitory potency in NHP when compared to human explants. In NHPs, higher TFV concentrations were measured in colorectal versus cervicovaginal explants (p = 0.042). In humans, this relationship was inverted with lower levels in colorectal tissue (p = 0.027). TFV-resistance caused greater loss of viral fitness for HIV-1 than SIV. This, tissue explants provide an important bridge to refine and appropriately interpret NHP studies. Tenofovir-maraviroc combinations show greater potency in NHP than in human tissue Opposite drug distribution in mucosal tissues was observed between both species Greater loss of viral replication fitness with RT mutations for SIV than for HIV-1 Ex vivo tissue models are a bridge between NHP studies and human clinical trials
