Which immunoglobulin is known to be very effective against parasites?

The immunoglobulin that is known to be very effective against parasites is IgE. IgE plays a crucial role in the body’s immune response to parasitic infections, particularly helminths (worms), and in allergic reactions. It is produced in response to specific allergens and pathogens, and it binds to the surface of mast cells and basophils. When these cells encounter an antigen that matches with IgE, they release chemicals like histamine, which can lead to inflammation and activation of other immune cells to combat the invaders.

This is particularly important in the context of parasitic infections, as the immune system needs to mount a strong response to eliminate these larger pathogens, which cannot be easily phagocytized by immune cells. Other immunoglobulins also play important roles in immune responses, but their functions focus on different types of infections or aspects of immunity, making IgE distinctly suited for targeting parasites.
