Discuss how neutrophils can destroy pathogens

WebFrom there, the neutrophils can destroy the pathogen using two methods - they can use their cytoplasmic granules or oxidative burst. First, the cytoplasmic granules fuse with the phagosome to form the phagolysosome. The granules contain molecules that lower the pH of the phagolysosome, making it very acidic, and that kills about 2% of the ... WebWhen local infections are severe, neutrophils are attracted to the sites of infections in large numbers, and as they phagocytose the pathogens and subsequently die, their accumulated cellular remains are visible as pus at the infection site. Overall, inflammation is …
