在这篇综述中提出的研究探讨了三个不同的领域,有可能抑制妇女的艾滋病毒感染。根据来自女性生殖道(FRT)的生理学、内分泌学和免疫学的新信息,我们提出了保护妇女免受艾滋病毒感染的独特“正在进行的工作”。在月经周期中,雌二醇抑制了FRT免疫的各个方面,使妇女更容易感染艾滋病毒。当雌二醇水平升高时,通过设计共生乳杆菌分泌抗HIV分子Elafin,女性可以免受HIV感染。选择性雌激素反应调节剂增强屏障完整性,促进保护性抗hiv分子的分泌。最后,了解FRT内源性抗菌剂、蛋白酶、抗蛋白酶等在激素控制下的相互作用和调控,将为FRT粘膜微环境的治疗性操纵开辟新的途径。通过寻求预防妇女感染艾滋病毒的新办法,我们可能最终破坏艾滋病毒的流行。
The studies presented in this review explore three distinct areas with potential for inhibiting HIV infection in women. Based on emerging information from the physiology, endocrinology and immunology of the female reproductive tract (FRT), we propose unique ‘works in progress’ for protecting women from HIV. Various aspects of FRT immunity are suppressed by estradiol during the menstrual cycle, making women more susceptible to HIV infection. By engineering commensal Lactobacillus to secrete the anti-HIV molecule Elafin as estradiol levels increase, women could be protected from HIV infection. Selective estrogen response modifiers enhance barrier integrity and enhance secretion of protective anti-HIV molecules. Finally, understanding the interactions and regulation of FRT endogenous antimicrobials, proteases, antiproteases, etc., all of which are under hormonal control, will open new avenues to therapeutic manipulation of the FRT mucosal microenvironment. By seeking new alternatives to preventing HIV infection in women, we may finally disrupt the HIV pandemic.
