Ceramide regulates several different cellular responses including mechanisms leading to apoptosis. Serum- and glucocorticoid-inducible protein kinase (SGK)-1 is a serine threonine kinase, which activates survival pathways in response to stress stimuli. Recently, we demonstrated an anti-apoptotic role of SGK-1 in human umbilical endothelial cells treated(More)
BACKGROUND Colorectal cancer (CRC) infiltration by adaptive immune system cells correlates with favorable prognosis. The role of the innate immune system is still debated. Here we addressed the prognostic impact of CRC infiltration by neutrophil granulocytes (NG). METHODS A TMA including healthy mucosa and clinically annotated CRC specimens (n = 1491) was(More)
PURPOSE Colorectal cancer infiltration by CD16(+) myeloid cells correlates with improved prognosis. We addressed mechanistic clues and gene and protein expression of cytokines potentially associated with macrophage polarization. EXPERIMENTAL DESIGN GM-CSF or M-CSF-stimulated peripheral blood CD14(+) cells from healthy donors were cocultured with(More)
Polymorphonuclear cells (PMNs) contribute to the initiation and progression of the immune response by mediating cytotoxicity, phagocytosis, and cytokine secretion. Because CD44 serves as a cytotoxic-triggering molecule on PMNs, it was hypothesized that it could also trigger cytokine production. In this study, the effect of anti-CD44 antibodies on(More)
Human neutrophil elastase (HNE) and proteinase 3 (PRO3) are myeloid tissue-restricted serine proteases, aberrantly expressed by myeloid leukemia cells. PRO3 and HNE share the PR1 peptide sequence that induces HLA-A*0201-restricted cytotoxic T cells (CTLs) with antileukemia reactivity. We studied the entire HNE protein for its ability to induce CTLs. In an(More)
The clinical course of colorectal carci-noma (CRC) critically depends on cancer cell-intrinsic features, including specific mutations, microsatellite instability, and epigenetic alterations, as well as on the tumor microenvironment, as shaped by the interaction of malignant and non-transformed cells. Tumor infiltration by cellular components of the adaptive(More)
PURPOSE To investigate potential immunotherapeutic strategies in B lymphocytic malignancies we looked for CTLs recognizing CD19 and CD20 epitopes. EXPERIMENTAL DESIGN Three CD19 and CD20 peptides binding to HLA-A*0201 were identified and used to detect peptide specific CTLs by a quantitative real-time PCR to measure IFN-gamma mRNA expression in 23 healthy(More)
Clinical observations suggest that in chronic myelogenous leukemia (CML), the Philadelphia chromosome (Ph+) clone has a growth advantage over normal hematopoiesis. Patients with CML have high levels of neutrophil elastase, which has recently been shown to antagonize the action of granulocyte-colony-stimulating factor (G-CSF) and other growth factors. We(More)
Tumor associated antigens are useful in colorectal cancer (CRC) management. The ribosomal P proteins (P0, P1, P2) play an important role in protein synthesis and tumor formation. The immunogenicity of the ribosomal P0 protein in head and neck, in breast and prostate cancer patients and the overexpression of the carboxyl-terminal P0 epitope (C-22 P0) in some(More)
