Q: Cytokines that provide non specific immunity against virus are

Interferon is a group of proteins that increases the resistance of cells to viral infectionInterferon also acts as cytokines and are involved in the generation of the immune responses.Three types of interferons have so far been discovered, alpha, beta, and gamma, all of which have immune-modulating effects.Interferons are used in the treatment of cancer and autoimmune diseases.Thus, the correct answer is option D.

Q: Inflammatory response in an allergy is caused by the release of

Histamine is an organic nitrogenous compound involved in local immune responses as well as regulating physiological function in the gut and acting as a neurotransmitter. Histamine is involved in the inflammatory response. As part of an immune response to foreign pathogens, histamine is produced by basophils and by mast cells found in nearby connective tissues. Histamine increases the permeability of the capillaries to white blood cells and some proteins, to allow them to engage pathogens in the infected tissues.Thus, the correct answer is option C.
