Role of Toll-Like Receptors in Common Infectious Diseases of the Female Lower Genital Tract

The female reproductive tract consists of the vagina, cervix, uterus, and fallopian tubes. In particular, the lower region of the reproductive tract, which contains the vagina and cervix, is often attacked by various pathogenic microorganisms such as bacteria, fungi, and viruses. The immune response of the female lower genital tract is the first line of defense against pathogenic microorganisms. The toll-like receptors (TLRs), a critical pattern recognition receptor, are essential for fighting infections in the female lower genital tract. Here we give an overview of the current research on TLR expression in the female lower genital tract and review the role of TLRs and their signaling pathways in the identification of numerous pathogens in female lower genital tract infections. Our review will contribute to a deeper understanding of the connection between TLRs and the pathological mechanisms of female lower reproductive tract infections, serving as a reference for both fundamental research and preventative strategies for these diseases.
