Adhesins are surface structures on pathogens that allow them to adhere to host cells. They play a crucial role in the initial stages of microbial infection.
5 Must Know Facts For Your Next Test
Adhesins are essential for the attachment of pathogens to host tissues, which is a critical step in colonization and infection.
They can be composed of proteins, glycoproteins, or polysaccharides.
Common examples include pili, fimbriae, and viral spike proteins.
Adhesin-receptor interactions can determine the specificity of a pathogen for its host.
Disruption of adhesin function can prevent infection and is a target for therapeutic interventions.
