Cutaneous melanoma is highly immunogenic, yet primary melanomas and metastases develop successfully in otherwise immunocompetent patients. To investigate the local immunosuppressive microenvironment, we examined the presence of suppressor T lymphocytes and tolerising dendritic cells (DCs), the expression of immunosuppressive cytokines (IL-10, TGFbeta1 and(More)

The rates of exocytosis on the lysosomal hydrolase n-acetyl-beta D-glucosaminidase and beta-glucuronidase were measured in monolayer cultures of the C-6 glioma cell line. A comparison of the kinetics of release of the enzymes and the effects of cytochalasin B suggest that either intralysosomal localisation or the mechanism of release may be different for(More)
