Macrophage uptake and retention of radiolabeled glycopeptidolipid antigens associated with the superficial L1 layer of Mycobacterium intracellulare serovar 20.
Glycopeptidolipid (GPL) antigens which are associated with the superficial L1 layer of Mycobacterium intracellulare serovar 20 were labeled with radioisotopes by means of internal labeling techniques and used in macrophage uptake and retention studies. The use of tritiated alanine and phenylalanine allowed the incorporation of label into the GPL invariant fatty acyl peptide core, which is commo...
متن کاملStructure of the Specific Oligosaccharides from the Glycopeptidolipid Antigens of Serovars in the Mycobacterium auium-Mycobacterium
The specific oligosaccharide units of the C-mycosidic glycopeptidolipid antigens from serovarieties in the Mycobacterium avium-Mycobacterium intracellulare-Mycobacterium scrofulaceum complex were liberated as oligosaccharide alditols by treatment of the glycopeptidolipids with alkaline borohydride. The complete structures of the oligosaccharide alditols have been derived from their ‘H-NMR spect...
متن کاملIsolation and expression of a gene cluster responsible for biosynthesis of the glycopeptidolipid antigens of Mycobacterium avium.
Bacteria within the Mycobacterium avium complex are prominent in the environment and are a source of serious disseminated infections in patients with AIDS. Serovars of the M. avium complex are distinguished from all other mycobacteria and from one another by the presence of highly antigenic glycolipids, the glycopeptidolipids, on their surfaces. A genomic library of DNA from serovar 2 of the M....
متن کاملPostphagocytic detection of glycopeptidolipids associated with the superficial L1 layer of Mycobacterium intracellulare.
The superficial L1 layer of Mycobacterium intracellulare serovar 20 was detected by immunocytochemical procedures based on C-mycoside glycopeptidolipid (GPL) antigens. Specific immune serum was produced by injecting a GPL-methylated bovine serum albumin complex into rabbits with Freund incomplete adjuvant. The resulting antibodies were used to label serovar 20 with goat anti-rabbit immunoglobul...
متن کاملthe impact of musical texts on the text recall of young learners of english in isfahan junior high schools
abstract although music possesses some kind of power and using it has been welcome by many students in language classrooms, it seems that they take a non-serious image of the lesson while listening to songs and they may think that it is a matter of fun. the main objective of the present study was to investigate whether learning a foreign language through musical texts (songs) can have an impac...
