However, other studies demonstrated an important role of γδ T lymphocytes in adaptive response since they recognize antigens presented on the surface of antigen-presenting cells (APCs), and they have cytotoxic effect mediated by expression of granulysin [ 20] and perforin [ 19, 21].
DOI: http://dx.doi.org/10.7554/eLife.00778.002 An essential aspect of adaptive immunity is the ability of T cells to discriminate between structurally similar agonist and non-stimulatory self peptides bound to major histocompatibility complex (pMHC) molecules presented on the surface of antigen-presenting cells (APCs) (Weiss and Littman, 1994).
T cells become activated upon engagement of their TCRs by a cognate peptide-MHC ligand presented on the surface of an antigen-presenting or target cell.
10, 11 Activation of the immune system begins when a T-cell receptor recognizes and binds a foreign compound, or antigen, that is presented on the surface of an antigen-presenting cell.
Consequently, the simplest descriptions of the star patterns and of the motions of heavenly bodies are those presented on the surface of a sphere.
FTIR examination showed that there were oxygen-containing groups presented on the surface of the exfoliated graphite.
One common technique for measuring protein-binding affinities uses flow cytometry to analyze ligand binding to proteins presented on the surface of a cell.
Transmission electron microscopy was utilized to image the polymer-functionalized MWCNTs, showing relatively uniform polymer coatings presented on the surface of MWCNTs.
The origin of high DMM yield of the V2O5 MoO3/Al2O3 catalysts is explored and attributed to the synergistic effect of V and Mo mixed oxides presented on the surface of the catalyst.
SEM-EDX, XRD and XPS analyses showed that nanoscale Mg(OH 2 and MgO particles were presented on the surface of MgEC, which serve as the main adsorption sites for aqueous P.
The T cell receptor (TCR) determines the cellular response to antigens, which are presented on the surface of target cells in the form of a peptide bound to a product of the major histocompatibility complex (pepMHC).
