Adhesins are molecules on the surface of pathogens that allow them to bind to host cells. They specifically recognize and attach to host factors such as fibronectin, sialic acid, and heparin/heparan sulfate, facilitating the pathogen's ability to infect host tissues. This specificity is crucial for the establishment of infection and disease progression.
