中和抗體（neutralizing antibody）是免疫系統産生的一類特異性抗體，能夠通過結合病原體（如病毒、細菌等）表面的關鍵抗原表位，直接阻斷其感染宿主細胞的能力。這類抗體的核心功能體現在“中和”作用上，即通過空間位阻或構象改變，阻止病原體與宿主細胞受體的結合，例如新冠病毒的刺突蛋白與人體ACE2受體的結合過程。
根據世界衛生組織的定義，中和抗體在疫苗效力評估中具有重要指示意義，其血清濃度常被用作衡量免疫保護力的生物标志物。美國國立衛生研究院的研究顯示，針對HIV病毒的中和抗體不僅能阻止病毒入侵，還能通過抗體依賴性細胞毒性作用（ADCC）清除被感染的細胞。
在臨床應用層面，單克隆中和抗體藥物已成功用于埃博拉病毒、狂犬病毒等急性感染的治療。中國疾病預防控制中心2023年發布的《中和抗體臨床應用指南》指出，這類生物制劑在暴露後預防中可使狂犬病發病率降低95%以上。值得注意的是，中和抗體的持續時間因病原體而異，例如麻疹疫苗誘導的中和抗體可維持數十年，而呼吸道合胞病毒（RSV）的中和抗體水平通常在數月内顯著下降。
中和抗體（neutralizing antibody）是一種能夠阻止病原體（如病毒、細菌）感染宿主細胞的抗體。以下是詳細解釋：
AI理性設計技術正推動廣譜中和抗體的開發，可同時針對多種病毒亞型（如甲型流感病毒Group 1和Group 2）。
