Secretory component‐dependent binding of immunoglobuin A in the rat, monkey and human: A comparison of intestine and liver
Christopher K. Daniels, Douglas L. Schmucker – 1 May 1987 – The source and significance of immunoglobulin A in bile remains controversial. In the rat, and several other species, immunoglobulin A is transported through hep‐atocytes by a specific receptor, secretory component. In humans, immunohistochemical methods have indicated a distinct lack of receptors for immunoglobulin A on hepatocytes. Binding assays with 125I‐immunoglobulin A and membranes from hepatocytes and intestinal cells of the rat display secretory component‐dependent binding.
