Toll 样受体 (TLR) 是哺乳动物先天免疫系统的关键受体之一。该家族的受体能够识别病原体结构中特定的高度保守的分子区域(模式),从而启动先天性和获得性免疫反应,最终消除病原体。在这种情况下,每种 TLR 类型都能够结合多种具有不同化学性质和结构的微生物来源分子。最近的数据表明,TLR 识别病原体存在多步机制,其中除了本身的受体外,还需要不同接头分子的参与。然而,单独的接头分子的功能以及配体特异性识别的多组分系统的形成原理仍然不太清楚。我们通过给出其简要特征来描述所有已识别的以及可能的(候选)衔接子TLR分子,并且我们还提出了涉及衔接子分子的TLR配体特异性识别的广义可能变体。
Toll-like receptors (TLR) are among key receptors of the innate mammalian immune system. Receptors of this family are able to recognize specific highly conserved molecular regions (patterns) in pathogen structures, thus initiating reactions of both innate and acquired immune response finally resulting in the elimination of the pathogen. In this case every individual TLR type is able to bind a broad spectrum of molecules of microbial origin characterized by different chemical properties and structures. Recent data demonstrate the existence of a multistep mechanism of the TLR recognition of the pathogen in which, in addition to receptors proper, the involvement of different adapter molecules is necessary. However, functions of separate adapter molecules as well as the principles of formation of a multicomponent system of ligand-specific recognition are still not quite understandable. We describe all identified as well as possible (candidate) adapter TLR molecules by giving their brief characteristics, and we also propose generalized possible variants of the TLR ligand-specific recognition with involvement of adapter molecules.
