Ⅱ型固有淋巴细胞在白色脂肪棕色化中的作用

正Ⅱ型固有淋巴细胞(typeⅡinnate lymphoid cells,ILC2s)于2001年被发现,由共同淋巴样祖细胞发育而来,广泛分布在血液、肠道、气管、肺脏、脾脏、肝脏、动物脂肪和皮肤等部位,经白细胞介素(interleukin,IL)-25或IL-33刺激后可产生IL-5和IL-13等2型辅助性T(type 2 helper T,Th2)细胞因子,在Th2

Role of type II innate lymphoid cells in browning of white adipose tissue

Type II innate lymphoid cells (ILC2s) are widely distributed in the blood, intestines, trachea, lung, spleen, liver, animal fat and skin, and involved in the innate immune responses. ILC2s have attracted much attention for its important roles in the conversion of white adipose to beige adipose. Studies have shown that ILC2s are essential for the proliferation and differentiation of adipocyte precursor cells, and they also play a vital role in anti-parasitic infection and allergic inflammation. This review discusses the discovery, differentiation, development, distribution and function of ILC2s, and their relationships with the browning of white adipose tissue for providing valuable references on understanding the pathogenesis, prevention and treatment of obesity and fat metabolism disorders.
