(1) Some of those drugs are able to stimulate the macrophages, even in an aspecific way, via the gut associated lymphatic tissue (GALT), that is in connection with the bronchial associated lymphatic tissue (BALT).
(2) The BSF have augmenting effects on class-specific Ig production by GALT sIgM-bearing B cells, when these are treated with the BSF alone.
(3) The effect of Cyclosporin (CS) on the gut-associated lymphoid tissue (GALT) of inbred WKA rats was immunohistochemically studied by the immunoperoxidase method.
(4) Lymphocytes from a patient with classic galactosemia (GALT deficiency) were hybridized with a Chinese hamster cell line.
(5) Evaluation of the human GALT enzyme suggests that its locus is not on the deleted segment.
(6) The finding of an N-terminal hydrophobic segment which serves as the membrane anchor and signal sequence suggests that the C-terminal region of the GalT polypeptide is oriented within the lumen of the Golgi membranes.
(7) The association of gastrointestinal (GI) and Waldeyer's ring lymphoma and the unique lymphocyte migration pattern of gut-associated lymphoid tissue (GALT) have been previously described.
(8) GALT contains Tcs cells which protect IgA responses under conditions of oral tolerance.
(9) It was demonstrated that stimulation of gut-associated lymphoid tissue (GALT) (either by direct injection or by ingestion of antigen) followed by local administration of antigen into the bronchus was required to enhance clearance in this model.
(10) Activity of beta 1,4-GalT was compared with glycosyltransferase activities that are considered to be specific for O-linked glycoproteins: UDP-Gal:N-acetylgalactosamine-beta 1,3-galactosyltransferase (beta 1,3-GalT), and UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase (Gal-NAcT).
(11) Unusual isoenzyme patterns for galactose-1-phosphate-uridyltransferase (GALT) and phosphoglucomutase1 (PGM1) were detected in the tumor, compared with normal human fibroblasts and blood cells and isoenzyme patterns from the patient's lymphocytes.
(12) To understand the mechanism(s) of this effect of LDL, we have studied here the effects of LDL on the activity of UDP-GalCer:beta-galactosyltransferase (GalT-2).
(13) Electrophoretic valuation of GALT in 31 independently derived interspecific hybrid clones failed to demonstrate expression of the human GALT gene even when human chromosome 9 was present.
(14) Similar experiments in rats which had been immunized actively by injecting antigens into the GALT showed a corresponding rapid decline in titres of specific biliary antibodies after fistulation of the thoracic duct.
(15) First, we examined the effect of exogenous IL2 on Ag-specific immunoglobulin (Ig) production by gut-associated lymphoid tissues (GALT) (Peyer's patches, PP; mesenteric lymph nodes, MLN) and non-GALT (spleen, SPN) cells.
(16) The immune system of the gastrointestinal tract (gut-associated lymphoid tissue--GALT) differs from the peripheral immune system in a number of points, and can also react largely independently of the latter.
(17) This conclusion is in agreement with previous biochemical studies which indicated that the 51-kDa and 42-kDa soluble forms of the enzyme which encompass the C-terminal 324 and 297 amino acid residues of the entire GalT polypeptide, respectively, include the catalytic site.
(18) These plasma cells did not occur in either lymphatic capillaries or HEV in BALT as they did in GALT.
(19) The availability of the enzyme GalT-2 and corresponding antibody will allow functional studies in the near future.
(20) The occurrence of cytokeratins, vimentin, and desmin in the dome epithelia and adjacent non-dome epithelia in four locations of gut-associated lymphoid tissues (GALT) of adult and newborn rabbits (Peyer's patches, sacculus rotundus, caecal lymphoid patches and appendix) was studied with monoclonal antibodies, using the indirect immunoperoxidase technique.
