经过几十年的沉寂 ,固有性免疫现已成为热门话题 ,研究主要聚焦于一种称为Ｔｏｌｌ样受体 (ＴＬＲｓ)的受体分子家族 ,在激发固有性免疫反应中发挥着主导作用 ,位于哺乳类动物巨噬细胞及树突状细胞以及某些组织 (如 :肠腔、鼻腔 )上皮细胞表面。无脊椎动物缺乏适应性免疫系统 , After decades of silent, innate immunity has now become a hot topic, and the research has focused primarily on a family of receptor molecules called Toll-like receptors (TLRs) that play a leading role in eliciting an innate immune response, Mammalian macrophages and dendritic cells as well as certain tissues (such as: intestine, nasal cavity) epithelial cell surface. Invertebrates lack an adaptive immune system,
