  • Tissue tropism mechanisms
  • Immune system evasion
  • Biofilm formation
Anti-Adhesion Therapeutics

Development of novel therapeutic strategies targeting bacterial adhesion as alternatives to antibiotics.

  • Small-molecule adhesion inhibitors

Basics
Introduction to Bacterial Adhesins: Structure, Function, and Pathogenic Role

The main structural classes of adhesins, how receptor specificity shapes tissue tropism, and why adhesins are studied as vaccine and drug targets.

Biofilms
Biofilm Formation: How Bacterial Adhesins Drive Surface Colonization

From first contact with a surface to a mature, antibiotic-tolerant community: the role adhesins play at each stage of biofilm development.

Anti-Adhesion
Anti-Adhesion Therapy: FimH Antagonists, Pilicides and Anti-Biofilm Strategies

Investigational approaches that aim to stop bacteria attaching rather than killing them, with key literature references.
