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)
BACKGROUND NSCLC exhibits considerable heterogeneity in its sensitivity to chemotherapy and similar heterogeneity is noted in vitro in a variety of model systems. This study has tested the hypothesis that the molecular basis of the observed in vitro chemosensitivity of NSCLC lies within the known resistance mechanisms inherent to these patients' tumors. (More)
BACKGROUND Ovarian cancer shows considerable heterogeneity in its sensitivity to chemotherapy both clinically and in vitro. This study tested the hypothesis that the molecular basis of this difference lies within the known resistance mechanisms inherent to these patients' tumours. METHODS The chemosensitivity of a series of 31 ovarian tumours, all(More)
1 Background Atopic dermatitis (AD) is a disorder of inflammation in the skin and is strongly associated with other inflammatory epithelial atopic conditions (asthma, allergic rhinitis and food allergy). The pathogenesis of AD results from complex interactions between susceptibility genes encoding skin barrier molecules and markers of the inflammatory(More)
BACKGROUND Dendritic cells (DC) play the key role in directing antigen-specific immune responses and manipulating their function may be a useful tool for immunotherapy. The balance between immune stimulation and tolerance is particularly important at mucosal interfaces, where discrimination between dangerous pathogens and innocuous antigens takes place. In(More)
