摘要牧草在世界范围内广泛种植，最常见的3种致敏性牧草花粉亚科分别为：温带的早熟禾亚科（ Pooideae）、亚热带的虎尾草亚科（ Chloridoideae）和黍亚科（ Panicoideae）。本文解读欧洲过敏和临床免疫学会（EAACI）发布的《过敏原组分诊断指导建议2.0》中关于牧草花粉过敏原组分的研究进展和临床应用，并整理了国内外牧草花粉的流行情况、过敏原组分蛋白家族的特征、临床表现和治疗指南，旨在提高相关专业人员对过敏原组分的深入认识以精准区分牧草花粉过敏患者和对泛过敏原的反应，为探讨中国特色的牧草花粉致敏特征提供新的思路以及临床实践提供更加个体化、有针对性的诊断和治疗方案。

abstractsGrasses are extensively cultivated worldwide, with the three most common allergenic grass pollen subfamilies being Pooideae in temperate regions, Chloridoideae and Panicoideae in subtropical areas. This article delves into the research progress and clinical applications of grass pollen allergy as delineated in the "Molecular Allergology User′s Guide 2.0" issued by the European Academy of Allergy and Clinical Immunology (EAACI). It compiles epidemiological data on grass pollen, allergenic components, clinical manifestations, and treatment guidelines from both domestic and international sources, providing cutting-edge insights and scientific perspectives for professionals in the field of pollen allergy. The aim is to enhance the understanding of allergenic components, distinguishing between grass pollen allergy and pan-allergen responses with precision through advanced component-resolved diagnostic techniques. This serves to foster novel approaches to characterizing the unique sensitization patterns of grass pollen allergens in China, thereby offering more personalized and targeted diagnostic and therapeutic strategies for clinical practice in the region.
