Immune system dynamics in response to Pseudomonas aeruginosa biofilms

Pseudomonas aeruginosa biofilms contribute to chronic infections by resisting immune attacks and antibiotics. This review explores how innate immunity, including neutrophils, macrophages, and dendritic cells, responds to biofilms and how adaptive mechanisms involving T cells, B cells, and immunoglobulins contribute to infection persistence. Additionally, it highlights immune evasion strategies and discusses emerging therapies such as immunotherapy, monoclonal antibodies, and vaccines, offering insights into enhancing biofilm clearance and improving treatment outcomes.
