Newborn infants have little or no secretory IgA (SIgA) at birth. Earlier studies suggest that premature infants do not significantly differ from term babies in their rate of acquisition of SIgA.

Scientists at UMC Utrecht have developed a new technology to efficiently isolate a specific subset of gut bacteria from fecal samples that are recognized by IgA antibodies. These "IgA-coated" bacteria ...

First, antibodies (i.e., secretory IgA) in the mucosa neutralize S ... impede proper humoral response (antibody generation) to the bacteria and also deplete certain subtypes of T-cells (via ...

Upper respiratory tract infection (URTI) is a common illness. Recent studies have shown that suppression of secretory immunoglobulin A (SIgA) is associated with increased incidence of URTI. Objective: ...

[16] Breast milk contains high concentration of secretory antibodies, mainly IgA, with a broad range of specificities reflecting both maternal immunologic memory and antigenic stimulation of ...

Secretory IgA is the main effecter in mucosal immunity and acts as a first line of defence in the host immunity system. Exercise is known to modulate the production of specific antibody and it is ...
