The immune system: A functional perspective

摘要: Abstract The immune system consists of a heterogenous collection cells that are exquisitely designed to function as means protection from colonization by infectious agents. comprising the described well their development and function. is tightly regulated signals transmitted soluble substances (interleukins) modulation expression cell surface proteins.
