In the lymphoid system, T cells respond to space or under-crowding by dividing to maintain their numbers. In this issue of Cell, evidence is provided that this homeostatic proliferation, coupled with excess production of a cytokine, IL-21, is a key factor in susceptibility to autoimmune diabetes.
在淋巴系统中,T细胞通过分裂来维持自身数量,以应对空间或细胞密度不足的情况。在本期《细胞》杂志中,有证据表明这种稳态增殖,再加上一种细胞因子IL-21的过量产生,是易患自身免疫性糖尿病的关键因素。
