Effect of Soluble HLA Class I Molecule on NK/LAK Cells Activation Induced by Poly I:C
Background: Natural Killer cells express killer inhibitory receptors specific for HLA-class I molecules. These receptors could induce signals that determine NK cells ability to mediate cytotoxicity. Purified soluble form of HLA class I molecules (sHLA) could bind to NK cell receptors and down-regulate the NK killer function. Objective: To evaluate the influence of sHLA and two monoclonal an...
متن کاملCross-presentation of HLA class I epitopes from exogenous NY-ESO-1 polypeptides by nonprofessional APCs.
NY-ESO-1, a germ cell Ag often detected in tumor tissues, frequently elicits Ab and CD8(+) T cell responses in cancer patients. Overlapping long peptides spanning the NY-ESO-1 sequence have been used to map HLA class I-restricted epitopes recognized by NY-ESO-1-specific CD8(+) T lymphocytes. To address the antigenicity of long peptides, we analyzed two synthetic 30-mer peptides from NY-ESO-1, p...
متن کاملProcessing and presentation of exogenous HLA class I peptides by dendritic cells from human immunodeficiency virus type 1-infected persons.
Dendritic cells (DCs) loaded with viral peptides are a potential form of immunotherapy of human immunodeficiency virus type 1 (HIV-1) infection. We show that DCs derived from blood monocytes of subjects with chronic HIV-1 infection on combination antiretroviral drug therapy have increases in expression of HLA, T-cell coreceptor, and T-cell activation molecules in response to the DC maturation f...
متن کاملUpregulation of HLA Class I Expression on Tumor Cells by the Anti-EGFR Antibody Nimotuzumab
Defining how epidermal growth factor receptor (EGFR)-targeting therapies influence the immune response is essential to increase their clinical efficacy. A growing emphasis is being placed on immune regulator genes that govern tumor - T cell interactions. Previous studies showed an increase in HLA class I cell surface expression in tumor cell lines treated with anti-EGFR agents. In particular, e...
متن کاملDetection of GAD65 Autoreactive T-Cells by HLA Class I Tetramers in Type 1 Diabetic Patients
Type 1 diabetes (T1D) is an autoimmune disease, in which pancreatic beta cells are destroyed in genetically predisposed individuals. While the direct contribution of autoantibodies to the disease pathogenesis is controversial, it is generally recognised that the mechanism of beta cell destruction is mediated by autoreactive T cells that had escaped the thymic selection. We aimed to design a met...
