Emerging Insights into Protein Post-Translational Modifications in Chlamydia-Host Interactions

Chlamydia species are responsible for significant diseases in both humans and animals, with their infection processes involving complex interactions with host cells. Protein post-translational modifications (PTMs) have emerged as a critical focus in understanding the complex interplay between Chlamydia and its host. PTMs, including phosphorylation, glycosylation, ubiquitination, acetylation, and methylation, play pivotal roles in regulating key processes during Chlamydia infection, such as bacterial invasion, intracellular survival, immune evasion, and manipulation of host signaling pathways. By modulating both bacterial and host proteins, PTMs serve as essential mechanisms that shape the progression and outcome of Chlamydia infections. This growing area of research not only deepens the understanding of Chlamydia's pathogenic strategies but also opens new avenues for developing targeted therapeutic interventions against these infections.
