- Proteoglycan subunits (PGS) were isolated from bovine articular cartilage of calves and from cows, 18 months and 8 years old respectively. From the latter cartilage of osteoarthrotic and of non-osteoarthrotic sites was taken. PGS were characterized by gel-chromatography on Sepharose 2B columns and subjected to digestion with chondroitinase ABC and with papain. The isolated keratan sulphate-protein cores obtained from chondroitinase digestion were characterized on Sepharose 4B and the chondroitin sulphate chains on Sephadex G-200 gels. A larger molecular size of PGS was found in calf cartilage than in the other samples. This was attributed to the larger molecular size of chondroitin, whereas no change was observed in the keratan sulphate-protein cores. No change was observed in molecular size of PGS, isolated chondroitin sulphates or keratan sulphate-protein cores in osteoarthrosis in compariith non-osteoarthrotic cartilage from the same joint or from younger adult animals.

Skeletal keratan sulfate peptides from different tissues : Characterization and alkaline degradation.

- Keratan sulfate-rich peptides were isolated after digestion of proteoglycans from bovine nasal cartilage and bovine nucleus pulposus with chondroitinase ABC, trypsin and chymotrypsin. The keratan sulfate enriched peptides from nucleus pulposus were larger than those from nasal cartilage. Keratan sulfate chains were isolated after treatment of the keratan sulfate-rich peptides under alkaline, reductive conditions. Proteoglycans from nucleus pulposus contain longer keratan sulfate chains, as is shown primarily by gel chromatography of the keratan sulfate-rich peptides and the keratan sulfate chains, but also from end-group analyses of the keratan sulfate chains.

In vitro-uptake of L-Dopa and catecholamines into the epidermal Langerhans cell
- 1978
-
Ingår i: Acta dermato-venereologica. Supplementum. - 0365-8341. ; 79, s. 31-35
-
Tidskriftsartikel (refereegranskat)abstract
- The Langerhans cells are capable of taking up L-dopa and the catecholamines dopamine and noradrenaline when exposed to these substances in vitro. Within the cell L-dopa is found in the cytoplasm as well as in the nucleus, whereas the catecholamines are confined to cytoplasmic granules. The L-dopa uptake is most probably carrier-mediated and the hypothesis is brought forward that L-dopa enters the cell by exchange diffusion. At present little is known about the nature of the amine uptake mechanism.
