cationic proteins and defensins
that are used to kill bacteria, proteolytic enzymes and cathepsin G to break down (bacterial) proteins, lysozyme to break down bacterial cell walls, and myeloperoxidase (used to generate toxic bacteria-killing substances).

What does the immune system use to identify pathogens?
Pathogens are recognized by a variety of immune cells, such as macrophages and dendritic cells, via
pathogen-associated molecular patterns (PAMPs)
on the pathogen surface, which interact with complementary pattern-recognition receptors (PRRs) on the immune cells’ surfaces.
Which WBC has shortest lifespan?
