Abstract:
Pneumonia is a common acute infectious disease affecting the lower respiratory tract. Innate immune cells within the lungs play a crucial role in the onset and progression of pneumonia. Various multidrug-resistant bacteria have evolved multiple strategies to evade innate immunity, posing significant challenges to the treatment of pneumonia. This review primarily explores the major innate immune cells in the lungs and their functions, the immune evasion mechanisms of common multidrug-resistant bacteria, and the latest research advances in targeted innate immunity-based anti-infective therapies. This review synthesizes recent advances in the interaction between the innate immune system of the lungs and multidrug-resistant bacteria. It systematically categorizes and compares the immune evasion mechanisms of multidrug-resistant bacteria across four core pathways. This aims to provide novel insights for treating pulmonary infections caused by these multidrug-resistant pathogens.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
