Abstract

The ability of myeloid cells to recognize and differentiate endogenous or exogenous ligands rely on the presence of different transmembrane protein receptors. C-type lectin receptors (CLRs), defined by the presence of a conserved structural motif called C-type lectin-like domain (CTLD), are a crucial family of receptors involved in this process, being able to recognize a diverse range of ligands from glycans to proteins or lipids and capable of initiating an immune response. The Dectin-1 and Dectin-2 clusters involve two groups of CLRs, with genes genomically linked within the natural killer cluster of genes in both humans and mice, and all characterized by the presence of a single extracellular CTLD. Fundamental immune cell functions such as antimicrobial effector mechanisms as well as internalization and presentation of antigens are induced and/or regulated through activatory, or inhibitory signalling pathways triggered by these receptors after ligand binding. In this review, we will discuss the most recent concepts regarding expression, ligands, signaling pathways and functions of each member of the Dectin clusters of CLRs, highlighting the importance and diversity of their functions.

Dectin-1 和 Dectin-2 簇：在免疫中发挥重要作用的 C 型凝集素受体。

髓系细胞识别和分化内源性或外源性配体的能力依赖于不同跨膜蛋白受体的存在。C型凝集素受体（CLRs）由一个名为C型凝集素样结构域（CTLD）的保守结构基团定义，是参与这一过程的重要受体家族，能够识别从糖类到蛋白质或脂类的各种配体，并能启动免疫反应。Dectin-1和Dectin-2簇涉及两组CLR，其基因在人类和小鼠的自然杀伤基因簇中都有基因组联系，其特点都是存在单一的细胞外CTLD。免疫细胞的基本功能，如抗菌效应机制以及抗原的内化和呈递，都是在配体结合后通过这些受体触发的激活或抑制信号通路诱导和/或调节的。在这篇综述中，我们将讨论有关 CLRs Dectin 簇中每个成员的表达、配体、信号传导途径和功能的最新概念，强调其功能的重要性和多样性。

期刊介绍： EMBO Reports is a scientific journal that specializes in publishing research articles in the fields of molecular biology, cell biology, and developmental biology. The journal is known for its commitment to publishing high-quality, impactful research that provides novel physiological and functional insights. These insights are expected to be supported by robust evidence, with independent lines of inquiry validating the findings. The journal's scope includes both long and short-format papers, catering to different types of research contributions. It values studies that: Communicate major findings: Articles that report significant discoveries or advancements in the understanding of biological processes at the molecular, cellular, and developmental levels. Confirm important findings: Research that validates or supports existing knowledge in the field, reinforcing the reliability of previous studies. Refute prominent claims: Studies that challenge or disprove widely accepted ideas or hypotheses in the biosciences, contributing to the correction and evolution of scientific understanding. Present null data: Papers that report negative results or findings that do not support a particular hypothesis, which are crucial for the scientific process as they help to refine or redirect research efforts. EMBO Reports is dedicated to maintaining high standards of scientific rigor and integrity, ensuring that the research it publishes contributes meaningfully to the advancement of knowledge in the life sciences. By covering a broad spectrum of topics and encouraging the publication of both positive and negative results, the journal plays a vital role in promoting a comprehensive and balanced view of scientific inquiry.
