Immunoglobulin Content of Intestinal Mucosal Plasma-Cells in Ataxia Telangiectasia

Recent Progress in Immune Responses in Gut

“…IgM is the major secretory immunoglobu lin in the intestinal tract of children [40], young animals [41], IgA-deficient individu als [42] and during the early local immune response in humans [43], Like mucosal IgA, it is able to combine with SC in vitro [44]. Evidence for direct activity of IgM within the intestinal lumen is limited.…”

Immunologic responses to bacteriophage ϕX 174 in immunodeficiency diseases

“…The clinical and laboratory findings of these patients are characterized in Table I. Methods for studies summarized in Table I have been published (11)(12)(13). Some of these cases have been reported in part previously; references are cited in the Table. For convenience in presentation, the 26 patients are divided into four groups.…”

Immunohistologic Localization of Immunoglobulins, Secretory Component, and Lactoferrin in the Developing Human Fetus

“…Tissue specimens were prepared for cryostat sectioning according to the method described by Eidelman and Davis (10). Specimens were fixed in isotonic buffered formaldehyde, followed by an overnight wash in 30% sucrose solution.…”

“…Photographs were taken on Kodak high speed film. [8][9][10][11][12] week old fetuses. As shown in Table I no immunofluorescence was detected against yA, yM immunoglobulins, and LF in any of the specimens tested, except in an occasional polymorphonuclear leukocyte contained in mesentery of an eight week fetus.…”
