PubMed PubMed Product Detail Monomeric IgA constitutes 5-15 % of the serum immunoglobulins whereas dimeric IgA is localized to mucosa surfaces such as saliva, gastrointestinal secretion, bronchial fluids and milk. Mucosal IgA plays a major role in host defence by neutralising infectious agents at mucosal surfaces. The production is usually local and antigen specific IgA producing B-cells can be found in regions under the lamina propria where they mature into dimeric IgA producing plasma cells. IgA deficiency is the most common immunodeficiency that may affect both serum and mucosal produced IgA.

IgA有IgA1和IgA2两个亚类。IgA1主要存在于血清中，约占血清中IgA的85%，α1链分子量为56kD；IgA2主要存在于外分泌液中，少部分以血清型IgA存在，约占血清中IgA的15%，α2链缺乏铰链区，分子量为52kD。血清中的IgA除单体形式外还有由J链共价相连的二聚体或三聚体等形式。分泌型IgA是由J连接的双体和分泌成分所组成，主要存在于初乳、唾液、泪液、胃肠液、支气管分泌等外分泌液中，是粘膜局部免疫的最重要因素，分泌型IgA通过与相应的病原微生物（如脊髓灰质炎病毒）结合，阻抑其吸附到易感细胞上，分泌型IgA还可中和毒素如霍乱弧菌毒素和大肠杆毒素等。Product Picture
