In our last lecture, we studied phagocytosis as a component of innate host defense. In today‚Äôs lecture, we shall study various antimicrobial proteins (enzymes inclusive), in blood and tissue fluids, that provide the body with innate defenses against pathogenic microbes. The body produces these enzymes and proteins at any given time and they mostly circulate […]
