Question

Quizplus · Accepted Answer

Cytokines are chemical messengers released by immune cells, including macrophages and dendritic cells, that activate a variety of other immune cells.

Answer: G
 An antigen is a substance that elicits an immune response, typically by binding to an antibody or a T cell receptor.

Answer: C
 Interferons are proteins released by cells in response to viral infections or other stimuli, that help to activate immune cells and prevent viral replication.

Answer: D
 Antibodies are proteins produced by B cells in response to antigens, that can bind to and neutralize specific pathogens or foreign substances.

Answer: E
 Pyrogens are substances, such as bacterial toxins or cytokines, that can cause fever by increasing the body's temperature set point in the hypothalamus.

Answer: A and B
 Keratin is a tough, fibrous protein found in skin, hair, and nails, and perforins are proteins released by cytotoxic T cells and natural killer cells, that can create pores in target cell membranes to induce cell death. Neither is directly related to immune activation by cytokines or recognition of foreign antigens.
