While IgA1 predominates in serum (~80%), IgA2 percentages are higher in secretions than in serum (~35% in secretions); [10] the ratio of IgA1 and IgA2 secreting cells varies in the different lymphoid tissues of the human body: [11] IgA1 is the predominant IgA subclass found in serum. Most lymphoid tissues have a predominance of IgA1-producing ...

It encodes a constant (C) segment of Immunoglobulin A heavy chain. Immunoglobulin A is an antibody that plays a critical role in ...
Selective immunoglobulin A (IgA) deficiency (SIgAD [1]) is a kind of immunodeficiency, a type of hypogammaglobulinemia.People with this deficiency lack immunoglobulin A (IgA), a type of antibody that protects against infections of the mucous membranes lining the mouth, airways, and digestive tract.
α – IgA, further divided into subclasses IgA1 and IgA2; δ – IgD; γ – IgG, further divided into subclasses IgG1 to IgG4; ε – IgE; μ – IgM; There are also two light chain isotypes κ and λ; however, there is no significant difference in function between the two. Thus an antibody isotype is determined by the constant regions of the ...
Thus, the IgA protease act by cleaving the proline-rich hinge region of the heavy chain of IgA1. Three major bacteria , Neisseria meningitidis , Streptococcus pneumoniae , and Haemophilus influenzae type B, release the IgA protease which destroys IgA.
