Evidence that the inhibition of cartilage proteoglycan breakdown by mannosamine is not mediated via inhibition of glycosylphosphatidylinositol anchor formation.
The effect of mannosamine, an inhibitor of glycosylphosphatidylinositol (GPI) anchor formation, on chondrocyte-mediated cartilage proteoglycan breakdown was investigated using cartilage explant cultures. Mannosamine inhibited interleukin 1alpha-, tumour necrosis factor alpha- and retinoic acid-stimulated proteoglycan release from bovine nasal and articular cartilage, and retinoic acid-stimulate...
متن کاملThe mechanism of inhibition of glycosylphosphatidylinositol anchor biosynthesis in Trypanosoma brucei by mannosamine.
The inhibition of glycosylphosphatidylinositol anchor biosynthesis by mannosamine has been described previously in the procyclic forms of Trypanosoma brucei and in mammalian cells (Lisanti, M. P., Field, M. C., Caras, I. W. J., Menon, A. K., and Rodriguez-Boulan, E. (1991) EMBO J. 10, 1969-1977). A recent report has suggested that mannosamine exerts these effects by becoming incorporated into g...
متن کاملInhibition of glycosylphosphatidylinositol biosynthesis in Leishmania mexicana by mannosamine.
In several Leishmania species, glycosylated inositol phospholipids exist as free lipids, as membrane protein anchors, and as the membrane-binding moieties of the lipophosphoglycans. Both the glycolipid-anchored cell surface metalloproteinase, gp63, and the lipophosphoglycans have been proposed to be involved in cell invasion. Moreover, the lipophosphoglycans have been implicated in the survival...

15 صفحه اولEnhanced responses of glycosylphosphatidylinositol anchor-deficient T lymphocytes.
The functions of GPI-anchored proteins in T lymphocyte activation have been controversial. This issue was addressed by studying the responses of T lymphocytes from T lymphocyte-specific GPI anchor-deficient mice to different stimuli that normally allow coligation of TCR and GPI-anchored proteins. Stimulation of GPI anchor-deficient T lymphocytes with ConA induced 2-fold higher proliferative res...
