White blood cells have been found to actively attack a giant parasite worm that infects the human body, according to new research. This discovery provides insight into the immune response against such parasites and could lead to potential new treatments for parasitic infections. The study showed that white blood cells are able to directly target and kill the parasite, suggesting that the immune system plays a significant role in defending against these types of infections. Understanding how the body's immune system responds to these parasites is crucial for developing effective therapies to combat them. Further research is needed to fully understand the mechanisms by which white blood cells are able to attack and eliminate the parasite, but this discovery opens up new possibilities for future treatments for parasitic infections.
