Verified step by step guidance

Understand the role of helper T cells in the immune response. Helper T cells are a type of lymphocyte that play a crucial role in the immune system by activating and directing other immune cells.

Recognize that activated helper T cells release signaling molecules to communicate with other immune cells. These molecules are essential for coordinating the immune response.

Identify the types of signaling molecules released by helper T cells. The primary molecules are cytokines, which include interleukins and interferons.

Differentiate between the options given: Antibodies and antigens are not released by T cells; they are involved in different immune functions. Histamines and prostaglandins are involved in inflammation and allergic responses, not directly in T cell signaling.

Conclude that the correct signaling molecules released by activated helper T cells to stimulate other immune cells are interleukins and interferons, which are types of cytokines.
