Pancreatic cancer is a very aggressive disease characterized by a marked desmoplasia with a predominant Th2 (GATA-3+) over Th1 (T-bet+) lymphoid infiltrate. We found that the ratio of GATA-3+/T-bet+ tumor-infiltrating lymphoid cells is an independent predictive marker of patient survival. Patients surgically treated for stage IB/III disease with a ratio(More)
Mutations in the X-linked cyclin-dependent kinase-like 5 (CDKL5) gene have been identified in patients with Rett syndrome, West syndrome, and X-linked infantile spasms sharing the common features of generally intractable early seizures and mental retardation. Disease-causing mutations are distributed in both the catalytic domain and in the large COOH(More)
CD36 is a membrane glycoprotein and a putative scavenger receptor expressed by several cell types. In capillary endothelial cells, it mediates the adherence of erythrocytes infected with Plasmodium falciparum. The CD36 sequence contains two hydrophobic domains located at the amino-and carboxyl-termini of the protein, but the topology of this protein and the(More)
Pancreatic cancer is a devastating disease with dismal prognosis. The tumor microenvironment is composed by multiple cell types, molecular factors, and extracellular matrix forming a strong desmoplastic reaction, which is a hallmark of the disease. A complex cross-talk between tumor cells and the stroma exists with reciprocal influence that dictates tumor(More)
CD36 is an integral membrane glycoprotein expressed by several cell types, including endothelial cells of the microvasculature, erythrocytes, platelets, and monocytes. In the monocytic lineage, CD36 is expressed during the late stages of differentiation in the bone marrow, in circulating monocytes, and in some tissue resident macrophages, and it is thought(More)
The structure of the CD38 molecule has been evaluated by one- and two-dimensional gel analysis and by enzymatic digestions. The source of the Ag was mainly membrane preparations obtained from MLC cells, from normal thymocytes, and from the plasmocytoma line LP-1. Membranes were solubilized in NP-40 and the extracts fractionated by immunoaffinity(More)
CD38 is a type II transmembrane glycoprotein, which is widely used as a marker for immature and activated lymphocytes, as well as plasma cells. Although its functional role and natural ligand are not known, CD38 has been shown to transduce activation signals to lymphocytes. Our work shows that CD38 is preferentially expressed by CD4+CD45RA+ cells, but not(More)
Parasite immunologists had known for some time that IgE-mediated hypersensitivity reactions are rare in patients with chronic helminth infections, even though basophils and mast cells in these patients are sensitized with antiparasite IgE and exposed, often continuously, to parasite antigens. The inhibition of allergic reactivity in chronic helminth(More)
We report the utilization of cord blood (CB) or bone marrow (BM) derived low density or purified CD34+ cells as a target for human multidrug resistance (MDR1) gene transfer. Cells were cocultivated for 48 h with an irradiated MDR1 retroviral producer line. Since some degree of MDR1 gene expression has been reported to occur in haemopoietic progenitor cells(More)
The CD38 antigen displays restricted functional associations with surface molecules involved in immune system and complement. Capping of the CD38 molecule in normal or neoplastic T cells is followed by rapid and specific co-modulation of the CD3-T cell receptor (TcR) complex. In normal and tumor cells of B lineage, CD38 was found to be also associated with(More)
