Summary Introduction
To review:
Role of interleukin-2.
Introduction:
Interleukin-2 is a cytokine that serves as a signaling molecule in the immune responses. This protein is responsible for the regulation of functions performed by leukocytes which play a role in immunity. It helps in the distinction of self from non-self. IL-2comprises of 133 amino acids with weight 15.42 kDa (kilo Dalton).
