Indirect immunofluorescent identification of 19S immunoglobulin-containing cells in the intestinal mucosa of Xenopus laevis. 1977

M Michea-Hamzehpour

The lymphoid structures in the gastrointestinal tract of immunized and non-immunized adult Xenopus laevis were studied by light and fluorescent microscopy. Serial sections stained with May-Grunnwald Giemsa showed that lymphoid aggregations and scattered lymphoid cells are present along the whole digestive tract. The aggregations are few and rather small in the oesophagus and stomach, they are particularly voluminous in the duodenum. An indirect immunofluorescent technique using antisera against Xenopus laevis 19S and 7S immunoglobulins and their heavy polypeptide chains, revealed the presence of immunoglobulin-containing cells in the duodenal region. The oesophagus and stomach were devoid of these. It has been shown that the immunoglobulins produced in the duodenal lamina propria are formed of both heavy and light polypeptide chains, and that the heavy chains are of the 19S H-type.

UI	MeSH Term	Description	Entries
D007075	Immunoglobulin M	A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin.	Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007413	Intestinal Mucosa	Lining of the INTESTINES, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. In the SMALL INTESTINE, the mucosa is characterized by a series of folds and abundance of absorptive cells (ENTEROCYTES) with MICROVILLI.

D008221	Lymphoid Tissue	Specialized tissues that are components of the lymphatic system. They provide fixed locations within the body where a variety of LYMPHOCYTES can form, mature and multiply. The lymphoid tissues are connected by a network of LYMPHATIC VESSELS.	Lymphatic Tissue,Lymphatic Tissues,Lymphoid Tissues,Tissue, Lymphatic,Tissue, Lymphoid,Tissues, Lymphatic,Tissues, Lymphoid
D004386	Duodenum	The shortest and widest portion of the SMALL INTESTINE adjacent to the PYLORUS of the STOMACH. It is named for having the length equal to about the width of 12 fingers.	Duodenums
D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000921	Antibody-Producing Cells	Cells of the lymphoid series that can react with antigen to produce specific cell products called antibodies. Various cell subpopulations, often B-lymphocytes, can be defined, based on the different classes of immunoglobulins that they synthesize.
