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. Subcellular Location: Secreted. SWISS: P01876 Gene ID: 3493 IgA有IgA1和IgA2兩個(gè)亞類。IgA1主要存在于血清中，約占血清中IgA的85%，α1鏈分子量為56kD；IgA2主要存在于外分泌液中，少部分以血清型IgA存在，約占血清中IgA的15%，α2鏈缺乏鉸鏈區(qū)，分子量為52kD。血清中的IgA除單體形式外還有由J鏈共價(jià)相連的二聚體或三聚體等形式。分泌型IgA是由J連接的雙體和分泌成分所組成，主要存在于初乳、唾液、淚液、胃腸液、支氣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通過與相應(yīng)的病原微生物（如脊髓灰質(zhì)炎病毒）結(jié)合，阻抑其吸附到易感細(xì)胞上，分泌型IgA還可中和毒素如霍亂弧菌毒素和大腸桿毒素等。 |
