Question: 1 / 400

Which of the following is a key characteristic of T cells?

They are responsible for antibody production

They directly attack cancer cells

They release chemicals that enhance the immune response

A key characteristic of T cells is their role in enhancing the immune response through the release of various signaling molecules, known as cytokines. These cytokines play an essential role in modulating the activity of other immune cells, creating a coordinated response that effectively fights off infections and malignancies.

While T cells are indeed involved in the direct attack on cancer cells and in cell-mediated immunity, their function extends beyond just attacking; they also facilitate and amplify the overall immune response. This enhances not only the activity of other immune cells, including B cells that produce antibodies, but also influences the development of a robust and effective adaptive immune response. Understanding this characteristic is crucial for comprehensive knowledge of T cell functions and their significance in immunology and cancer therapy.
