What is a key characteristic of Th2-type immune responses in relation to helminths?

The Th2-type immune response is particularly well-known for its role in combating parasitic infections, especially helminths. A key characteristic of this response is the facilitation of antibody production, specifically IgE antibodies. Upon recognition of a helminth, Th2 cells release cytokines such as IL-4, IL-5, and IL-13, which promote the activation and differentiation of B cells into plasma cells that produce IgE. This immunoglobulin plays a crucial role in mediating responses to helminths by binding to these parasites and promoting their clearance from the body.

Additionally, the production of antibodies helps recruit other immune cells to the site of infection and can enhance the overall effectiveness of an immune response through mechanisms such as opsonization and activation of the complement system. This aspect is fundamental to the adaptive immune response against helminths, which often require a robust antibody-mediated response due to their size and unique life cycles that can evade many conventional immune mechanisms.

In contrast, the other options do not accurately reflect the characteristic role of Th2 responses. While Th2 responses may have effects on phagocytic activity, they are not primarily characterized by inhibiting it, and they actually promote changes such as increased mucus secretion in muc
