Altered expression of nonclassical HLA class Ib antigens in human renal cell carcinoma and its association with impaired immune response
Abstract An optimal antitumoral immune response requires the activation of both CD8 + and CD4 + T lymphocytes by the peptide antigen presentation via the human leukocyte antigen (HLA) class I and class II molecules, respectively. Downregulation or loss of HLA molecules has been found in human renal cell carcinoma (RCC) and provides a strategy of these tumors to evade T-cell mediated immunosurveillance. In addition, a tumor-specific upregulation of HLA-G has been recently described in RCC, which also leads to an impaired immune response. We here summarize the frequency of the constitutive and/or interferon-γ (IFN-γ) inducible expression of nonclassical HLA class Ib antigens in RCC cell lines…
Identification of fatty acid binding proteins as markers associated with the initiation and/or progression of renal cell carcinoma
Renal cell carcinoma (RCC) representing the most common neoplasia of the kidney in Western countries is a histologic diverse disease with an often unpredictable course. The prognosis of RCC is worsened with the onset of metastasis, and the therapies currently available are of limited success for the treatment of metastatic RCC. Although gene expression analyses and other methods are promising tools clarifying and standardizing the pathological classification of RCC, novel innovative molecular markers for the diagnosis, prognosis, and for the monitoring of this disease during therapy as well as potential therapeutic targets are urgently needed. Using proteome-based strategies, a number of RC…
