Bacterial and host surface proteins

The term Bacterial and host surface proteins refers to a broad and heterogeneous category of proteins located on the exterior membranes of both bacterial pathogens and their respective host cells. These proteins play critical roles in the initial stages of infection, including bacterial adhesion, colonization, and invasion of host tissues. On the bacterial side, these include adhesins, invasins, and secretion systems, while host surface proteins often include receptors, integrins, and glycoproteins that are exploited by pathogens for entry. Because this term encompasses thousands of distinct proteins with diverse structures and functions, it does not represent a single, well-defined therapeutic target. In drug development, specific proteins within this category, such as Penicillin-binding proteins in bacteria or CCR5 in humans, are targeted individually to achieve therapeutic efficacy.
