Demonstration of IgA and secretory component in human hepatocytes.
By the immunoperoxidase technique, immunoglobulin A(IgA) was demonstrated in 50% of human hepatocytes. The positively stained cells showed a tendency towards periportal clustering. Very few plasma cells were identified in the liver. The intrahepatocyte IgA is most probably derived from serum and on its way to the bile ducts. Secretory component (SC) had the same distribution as that of IgA. The...
متن کاملMucosal secretory IgA and secretory piece in adult coeliac disease.
Immunofluorescence studies with specific antisera to secretory IgA (11S IgA) and secretory piece were carried out on the jejunal mucosa of nine patients with adult coeliac disease (treated and untreated). The results were compared with those obtained in four normal patients and in four patients with local and systemic IgA (7S) deficiency. 11S IgA and secretory piece were localized to the upper ...
متن کاملInteraction of rabbit secretory component with rabbit IgA dimer.
Secretory component (SC), a glycoprotein with an apparent molecular weight of approximately 80,000, has been isolated from rabbit milk and found to be heterogenous in size and charge. Functionally intact IgA dimer has been dissociated from milk secretory IgA using a chaotropic agent and further purified to homogeneity. The interaction between SC and IgA dimer is a reversible time- and temperatu...
متن کاملRelaxation training and breast milk secretory IgA.
OBJECTIVE To evaluate the hypothesis that breast-feeding women who participate in relaxation training will have increased secretory IgA (sIgA) levels in their breast milk compared with women not receiving training. DESIGN Nonrandomized control trial of a convenience sample. SETTING Women were recruited from the postpartum floor of a university teaching hospital. The intervention took place ...
متن کاملHigh levels of secretory IgA and free secretory component in the serum of rats with bile duct obstruction
In the rat , ligation of the bile duct induces a rapid and progressive elevation of the IgA levels in serum. The increase is about 4-fold at 1 h, 15-fold at 1 day, and 30-fold at 1 wk after ligation. The additional IgA is of the secretory type. Free secretory component also appears in serum after bile duct obstruction; it does not continue to increase and occasionally disappears from serum afte...
