早产儿脑白质损伤是低出生和极低出生体重儿脑损伤的主要形式,但其病因及发病机制尚未完全明确.目前认为Toll样受体在脑白质损伤的发病机制中起重要作用.Toll样受体是天然免疫受体家族,Toll样受体信号通路被激活可分泌大量TNF-α、IL-1β、活性氧、活性氮、NO等炎症因子,促使免疫应答反应发生.神经免疫应答对脑白质产生损伤,即脑内小胶质活化和星形胶质增殖.Toll样受体为脑白质损伤等疾病预防治疗提供新的研究方向.该文对Toll样受体在早产儿脑白质损伤性疾病中的研究进展作一综述.
早產兒腦白質損傷是低齣生和極低齣生體重兒腦損傷的主要形式,但其病因及髮病機製尚未完全明確.目前認為Toll樣受體在腦白質損傷的髮病機製中起重要作用.Toll樣受體是天然免疫受體傢族,Toll樣受體信號通路被激活可分泌大量TNF-α、IL-1β、活性氧、活性氮、NO等炎癥因子,促使免疫應答反應髮生.神經免疫應答對腦白質產生損傷,即腦內小膠質活化和星形膠質增殖.Toll樣受體為腦白質損傷等疾病預防治療提供新的研究方嚮.該文對Toll樣受體在早產兒腦白質損傷性疾病中的研究進展作一綜述.

White matter damage in premature infant is the main form of brain damage in low birth and very low birth weight children,but its etiology and pathogenesis is not fully clear.Present studies show that Tolllike receptors(TLR) play an important role in the white matter damage mechanism.TLRs are regulators of innate immune responses.The studies have found that TLRs signaling pathway is activated to secrete large amounts of TNF-α,IL-1β,reactive oxygen species (ROS) and reactive nitrogen (RNS),NO,and other inflammatory factors,inducing the immune response.Nerve immune response damages brain white matter,namely the activation of microglia and proliferation of astrocytes in brain.TLRs provide a new research direction for prevention and treatment.Therefore,the research and progress of toll-like receptors in premature brain white matter injury disease are
