Some people eith a deficit of IgA exhibit recurrent paranasal sinus and respiratory tract infections Explain these symptoms?
Immunoglobulin A (IgA) is an antibody playing a critical role in mucosal immunity. More IgA is produced in mucosal linings than all other types of antibody combined. In its secretory form, it is the main immunoglobulin found in mucous secretions, including tears, saliva, colostrum, intestinal juice, vaginal fluid and secretions from the prostate and respiratory epithelium. Because it is resistant to degradation by enzymes, secretory IgA can survive in harsh environments such as the digestive and respiratory tracts, to provide protection against microbes that multiply in body secretions.Because the respiratory tract and sinus cavities are mucosal entities, the infections manifest here.
How the plasma cell synthesis immunoglobulins A?
Immunoglobulin A (IgA) is the main effector of the mucosal surface and is an important first line of defense against most pathogens. It is also found in saliva, tears, and colostrum. IgA is produced by plasma cells as polymeric IgA consisting of two or more monomers linked by the J (joining) chain. It is then transfered to the epithelium and secreted. It is believed to interfere with pathogen adherence. IgA is also found as a monomer in the serum where it is a second line of defence against pathogens.
