Final answer:
Immune responses to parasitic infections include immunoglobulin production, antibody-dependent cell-mediated cytotoxicity, and cellular defenses like eosinophils and T lymphocytes. These mechanisms work together to effectively target and neutralize parasites within the body.
Step-by-step explanation:
The immune responses to parasitic infection include a broad range of mechanisms. These include immunoglobulin production by B cells, antibody-dependent, cell mediated cytotoxicity, and various cellular defenses, such as those provided by eosinophils and T lymphocytes. Immunoglobulins, or antibodies, specifically target pathogens and can be involved in neutralizing parasites. Eosinophils, which increase in number during parasitic infections, can attack parasites directly through the release of their granule contents. T lymphocytes are essential in coordinating adaptive immune responses, including the release of cytokines that attract eosinophils and the direct killing of infected cells. Together, these responses provide a multi-faceted defense system against parasitic infections.
