Answer:
Cytokines may be defined as the large group of the small protein that plays an important role in the immune system and cell signalling. They can also be used as immunodulating agents.
During the inflammation cytokine reach at the inflammation site. Cytokine shows the pleiotropy in which a single cytokine can perform different functions. They show redundancy in which different cytokine perform similar immune function. The synergistic phenomena in cytokine describe the increase in the cytokine activity in presence of another cytokine.
Answer:
Cytokines are the glycoproteins, or protein in nature that are released from the specific cells. These cells are part of the immune system that release these group of proteins that affects the role or function of the other cell by attaching the specific receptors.
Cytokines secreted in both adaptive and innate immunity. These are the molecules that acts as signaling molecules that leads to the regulation of the inflammation and immunity.
Thus, the correct answer- acts as the signalling molecule.
