Interleukin-12 (IL-12) is a heterodimeric protein, first recovered from EBV-transformed B cell lines. It is a multifunctional cytokine, the properties of which bridge innate and adaptive immunity, acting as a key regulator of cell-mediated immune responses through the induction of T helper 1 differentiation. By promoting IFN-g production, proliferation, and(More)
There is widespread interest in macrophages as a therapeutic target in cancer. Here, we demonstrate that trabectedin, a recently approved chemotherapeutic agent, induces rapid apoptosis exclusively in mononuclear phagocytes. In four mouse tumor models, trabectedin caused selective depletion of monocytes/macrophages in blood, spleens, and tumors, with an(More)
Activating BRAF or NRAS mutations have been found in 80% of human sporadic melanomas, but only one of these genetic alterations could be detected in each tumour. This suggests that BRAF and NRAS 'double mutants' may not provide advantage for tumour growth, or may even be selected against during tumorigenesis. However, by applying(More)
Axl, a member of the TAM (Tyro3, Axl, Mer) family of receptor tyrosine kinases, displays an increasingly important role in carcinogenesis. Analysis of 58 cutaneous melanoma lines indicated that Axl was expressed in 38% of them, with significant overrepresentation in NRAS- compared with BRAF-mutated tumors. Axl activation could be induced by autocrine(More)
Many human tumor-associated antigens (TAAs) have recently been identified and molecularly characterized. When bound to major histocompatibility complex molecules, TAA peptides are recognized by T cells. Clinical studies have therefore been initiated to assess the therapeutic potential of active immunization or vaccination with TAA peptides in patients with(More)
In this study, we investigated whether maturation of monocyte-derived myeloid dendritic cells (DCs) is differentially affected by the uptake of dying human melanoma cells in distinct phases of apoptosis. Maturation of monocyte-derived DCs, as documented by phenotype analysis and T-cell immunostimulatory activity, was inhibited by phagocytosis of dying(More)
The aim of this study was to evaluate the safety profile of s.c. administered recombinant human interleukin 12 (rHuIL-12). Pharmacokinetics and pharmacodynamics of rHuIL-12 and any evidence of antitumor effect were also considered. Ten pretreated patients with progressive metastatic melanoma were enrolled in this pilot study. Patients received a fixed dose(More)
We report that blood cell autografts, collected by single leukapheresis in cancer patients (n = 11) at the time of mobilization of hematopoietic progenitors into peripheral blood following anticancer therapy with high-dose cyclophosphamide (HD-CTX) plus interleukin-3 (IL-3) and granulocyte colony-stimulating factor (G-CSF/filgrastim), comprise 1.98 +/- 0.39(More)
Anaplastic lymphoma kinase (ALK) is a receptor tyrosine kinase predominantly expressed in the developing nervous system. Recently, mutated ALK has been identified as a major oncogene associated with familial and sporadic neuroblastomas (NBL). Yet, a direct correlation between endogenous expression level of the ALK protein, oncogenic potential, and clinical(More)
Because changes in the expression level of antigen-processing machinery (APM) components and HLA class I and II antigens in melanoma cells are expected to affect their interactions with the immune system of the host, we assessed the clinical relevance of quantitative variations in the expression of these molecules in melanoma lesions. Short-term (<10 in(More)
