Demonstration of the presence of IgA in the human chorioamniotic membrane.
The presence of IgA was detected by direct immunofluorescence techniques in the chorion and decidua of eight fragments of chorioamniotic membranes obtained near the rupture edge from eight normal patients. It is suggested that, similar to what occurs in other organic systems, a first barrier against infection of the amniotic chamber exists at this site.
