Design of soluble recombinant T cell receptors for antigen targeting and T cell inhibition.
The use of recombinant T cell receptors (TCRs) to target therapeutic interventions has been hindered by the naturally low affinity of TCR interactions with peptide major histocompatibility complex ligands. Here, we use multimeric forms of soluble heterodimeric alphabeta TCRs for specific detection of target cells pulsed with cognate peptide, discrimination of quantitative changes in antigen dis...
متن کاملSoluble extracellular antigen-specific T cell immunoproteins.
Some T cells release proteins that bind specifically to antigens that have not been processed by antigen-presenting cells. These soluble immunoproteins induce or effect antigen-specific T cell functions in immunoregulation and/or hypersensitivity. After certain immunization regimens, T cell immunoproteins specific for the immunogen rise in serum, and therefore may be an antigen-specific, humora...
متن کاملSoluble T cell receptors: novel immunotherapies.
T cell receptors are antigen-specific proteins that have evolved to recognize peptide antigens presented by human leukocyte antigen molecules on most cell types. Like antibodies, T cell receptors are produced with huge diversity but, unlike antibodies, T cell receptors are not secreted and do not undergo somatic mutations that increase their affinities for antigen. Recently, however, methods ha...
متن کاملProducing Soluble Human Programmed Cell Death Protein-1: A Natural supporter for CD4+T cell Cytotoxicity and Tumor Cells Apoptosis
Background: Programmed cell death protein-1 (PD-1)/PD-L1 pathway is one of the immune checkpoint pathways involved in regulation of the immune responses and suppression of anti-tumor defense. PD-1/B7-H1-blocking antibodies improve immune responses such as cytotoxic activity of CD8+/CD4+T cells and also increase mortality of tumor cells; however their use is accompanied by adverse effects in pat...
متن کاملB and T-Cell Epitope Prediction of the OMP25 Antigen for Developing Brucella melitensis Vaccines for Sheep
Brucellosis, produced by Brucella species, is a disease that causes severe economic losses for livestock farms worldwide Due to serious economic and medical consequences of this disease, many efforts have been made to prevent the infection through the use of recombinant vaccines based on Brucella outer membrane protein (OMP) antigens. In the present study, a wide range of on-line prediction sof...
