What is IgA deficiency and how does it affect you?
Your body makes IgA and other type of antibodies to help fight off sickness. Having an IgA deficiency means that you have low levels of or no IgA in your blood. IgA is found in mucous membranes, mainly in the respiratory and digestive tracts. It is also found saliva, tears, and breastmilk. A deficiency seems to play a part in asthma and allergies.
How does serum monomeric IgA mediate inhibitory signal?
Serum monomeric IgA is able to mediate an inhibitory signal following the interaction with FcαRI. It results in partial phosphorylation of its FcRγ-ITAM and the recruitment of the tyrosine phosphatase SHP-1, which induces cell inhibition following the formation of intracellular clusters named inhibisomes.
Where is Iga found in the body?
IgA is found in mucous membranes, mainly in the respiratory and digestive tracts. It is also found saliva, tears, and breastmilk. A deficiency seems to play a part in asthma and allergies. Researchers have also linked IgA deficiency to autoimmune health problems.
