Vaginal epithelial cell surface glycans

Vaginal epithelial cell surface glycans are complex carbohydrate structures, including N-linked and O-linked glycans, that form a dense layer known as the glycocalyx on the vaginal mucosa (Moncla et al., 2015, Journal of Medical Microbiology). These glycans serve as critical mediators of the vaginal microenvironment, acting as attachment sites for beneficial commensal bacteria like Lactobacillus, which are essential for maintaining vaginal health (García-Kassbi et al., 2022, Frontiers in Cellular and Infection Microbiology). However, these same glycans are often exploited by pathogens, such as HIV-1, Herpes Simplex Virus (HSV), and Candida albicans, as receptors or co-receptors to facilitate adhesion and subsequent infection (Nunn et al., 2015, Biology of Reproduction). The composition of these glycans can be influenced by hormonal changes during the menstrual cycle, which in turn affects the susceptibility of the vaginal epithelium to various infections (O'Hanlon et al., 2013, PLOS ONE). Therapeutic strategies targeting these glycans include the development of microbicides and lectins, such as Griffithsin, which bind to specific glycan motifs to block pathogen entry (O'Keefe et al., 2009, PNAS). Additionally, understanding the glycan profile of the vaginal epithelium is vital for the design of targeted probiotic therapies aimed at restoring a healthy microbiome. These interventions often focus on competitive inhibition, where therapeutic agents occupy glycan docking sites to prevent pathogen colonization or enhance the host's natural mucosal defenses.
