Final answer:
T Helper cells type 1 (Th1 cells) primarily assist macrophages in combating intracellular pathogens by secreting cytokines that enhance their ability to digest and destroy such pathogens. They are also key in effective immune responses by activating other immune cells, including cytotoxic T cells, neutrophils, and NK cells.
Step-by-step explanation:
Yes, the main function of T Helper cells type 1 (Th1 cells) is indeed to aid macrophages in fighting infections. The Th1 cells secrete cytokines that enhance the immunological activities of macrophages fighting intracellular pathogens, such as the bacteria Mycobacterium tuberculosis. These cytokines improve the digestive capabilities of macrophages, enabling them to efficiently destroy pathogens that have evolved to survive within them.
In addition to supporting macrophages, Th1 cells are involved in stimulating and coordinating the activities of other immune cells. They are integral in promoting the action of cytotoxic T cells and boosting the effectiveness of neutrophils and NK cells in the elimination of intracellular bacteria. Conversely, Th2 cells are more associated with stimulating B cells to combat extracellular pathogens through antibody secretion.
