Chlamydia trachomatis Antigens Overview
Chlamydia trachomatis antigens are molecular components derived from the bacterium *Chlamydia trachomatis*, a major human pathogen responsible for the most common sexually transmitted bacterial infection worldwide. These antigens are recognized by the host immune system and play critical roles in both pathogenesis and immune response. Key antigens include MOMP, Pgp3, and Type III secretion system effectors such as TarP and TmeA/B. These antigens are involved in host cell invasion, evasion or modulation of innate immune responses, and induction of adaptive immunity. They represent diagnostic targets and potential vaccine candidates.
