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.

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 ...

Thus low concentrations of lymphocytes, suppressed natural immunity, suppressed lymphocyte proliferation, and suppressed levels of secretory IgA in saliva are found simultaneously with high levels of ...

Therefore we have studied the interactions of IgA and human monocyte monolayer cultures. Secretory IgA derived from human breast milk and/or IgA derived from an EBV B cell line were used in these ...
