Why are cytokines important signals for cell-mediated immunity?

Cell-mediated immunity requires immune cells to communicate to perform most efficiently.

Cytokines are signals that allow immune cells to communicate.

Effector cells, like CD4 cells, use cytokines to activate other immune cells.

Cytokines signal to specific immune cells to increase their destructive properties and destroy pathogens.

A and B.

C and D.

Verified step by step guidance

Understand the role of cytokines: Cytokines are small proteins that are crucial in cell signaling, especially in the immune system. They help in the communication between cells to trigger the body's response to infection, inflammation, and trauma.

Recognize the importance of communication in cell-mediated immunity: Cell-mediated immunity relies on the interaction between different immune cells to effectively respond to pathogens. This requires efficient communication, which is facilitated by cytokines.

Identify the role of effector cells: Effector cells, such as CD4+ T cells, are essential in the immune response. They use cytokines to activate other immune cells, enhancing the immune response against pathogens.

Understand the signaling function of cytokines: Cytokines can signal specific immune cells to increase their destructive properties, enabling them to more effectively destroy pathogens and infected cells.

Evaluate the options: Given the roles of cytokines in communication, activation, and signaling within the immune system, all the provided statements (A, B, C, and D) are correct, highlighting the comprehensive importance of cytokines in cell-mediated immunity.
