Beyond the Barrier: Epithelial Cells as Immune Sentinels in the Female Genital Tract

American Journal of Reproductive Immunology, Volume 95, Issue 5, May 2026.
ABSTRACT Epithelial cells (ECs) of the female genital tract (FGT) serve as an essential barrier and the first line of defense against sexually transmitted pathogens. Beyond providing a physical barrier, these cells actively contribute to immune responses through pathogen recognition, cytokine release, and modulation of adaptive immune responses ...

Andrology, Volume 14, Issue 4, Page 1002-1016, May 2026.
Abstract The hypothalamic–pituitary–gonadal axis is regulated by the gonadotropin‐releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and ...
