Secretory immunoglobulin A in sweat gland tumors

Journal of Cutaneous Pathology, 1989
The presence of immunoglobulin A (IgA) and secretory component (SC) was investigated in normal human skin and in cutaneous neoplasms including a variety of sweat gland tumors. Immunohistochemistry in normal sweat glands revealed the occurrence of secretory IgA (sIgA) as indicated by reactivity for IgA and SC in serial sections. The majority of 28 cases

Studies on Human Secretory Immunoglobulin A

The Journal of Immunology, 1974
Abstract Fragments produced by cyanogen bromide cleavage of human secretory IgA were fractionated before and after the splitting of disulfide bonds on Sephadex G-200 columns in 5 M guanidine · HCl. By electrophoretic, antigenic, amino acid, and carbohydrate analyses of individual fractions it was revealed that J chain was released as a ...

Hidden Antigenic Determinant in Secretory Immunoglobulin A

Nature, 1968
IMMUNOGLOBULIN A (IgA) occurring in external secretions is composed of two 7S IgA units1–3 and an additional protein portion termed the transport piece4, αs-chain5, T-component1 or secretory piece6. The secretory piece occurs free in secretions devoid of immunoglobulins4 and in secretions containing immunoglobulin M (IgM) or immunoglobulin G (IgG) but ...

Secretory Immunoglobulin A: Autoantibody Activity in Gastric Juice

Science, 1968
An immunoglobulin A of the secretory variety, present in the gastric juice of a patient with pernicious anemia, was shown to have specificity for intrinsic factor. This is the first demonstration in gastric juice of antibody activity restricted to secretory IgA; further, this is the first example of an exocrine (gastric) immune system producing an ...

Degradation of human secretory immunoglobulin A by Blastocystis

Parasitology Research, 2005
Microbial immunoglobulin A (IgA) proteases cleave human secretory IgA, promoting the mucosal adhesion of pathogens. To investigate if the enteric protozoan Blastocystis degrades human secretory IgA, cell lysate and conditioned medium from two species were exposed to immunoglobulin A.

Emotional Crying, Depressed Mood, and Secretory Immunoglobulin A

Behavioral Medicine, 1993
The relationship between emotional crying and secretory immunoglobulin A (S-IgA) in whole saliva was examined. Previous research had indicated that lower S-IgA was associated with crying. Similar results were found in the present study. Depressed mood was not associated with S-IgA.

BIOLOGIC SIGNIFICANCE OF THE SECRETORY γA IMMUNOGLOBULINS

Pediatrics, 1971
The secretory γA globulins have been shown to be the active antiviral neutralizing principle in the respiratory tract. These antibodies are part of the system found in other fluids in contiguity with the exterior, the external secretory system. The presence of these γA associated antibodies has been shown to be correlated with protection particularly ...

[Secretory immunoglobulin A in amniotic fluid].

Zentralblatt fur Gynakologie, 1983
Secretory immunoglobulin A (S-IgA) was estimated in amniotic fluid samples by means of the single radial immunodiffusion according to Mancini. A monospecific antiserum against human secretory component was used. 163 amniotic fluid samples from normal pregnancies and risk pregnancies respectively were investigated.

Method used to isolate secretory component from secretory immunoglobulin A

2012
An attempt was made to isolate secretory component from the molecule secretory Immunoglobulin A. Two methods were used, each with colostrum as the source of secretory component. In the first method, colostrum was centrifuged, and the supernatant was chromatographed on a Sephadex G-200 column. Half of the eluates were concentrated by negative pressure
