How do platelets fights off germs?

Platelets play a crucial role in the immune response by not only aiding in blood clotting but also actively participating in fighting off infections. When they encounter pathogens, platelets can release antimicrobial substances and signaling molecules that help recruit immune cells to the site of infection. They also form aggregates that trap bacteria and viruses, preventing their spread. Additionally, platelets can enhance the activity of other immune cells, thereby bolstering the body's defense against germs.
