A method for increase the presentation of ETEC CS6 antigen on a cell surface, comprising the step of contacting cells expressing said antigen with an aqueous solution comprising 0.6-2.2 percent phenol by weight, such that the presentation of said antigen is increased by at least 100%. A ...

Herein, we present a novel finding that only the BMMC subset expressing high levels of FcεRI, concomitantly with high levels of MHC II on the cell surface, is capable of antigen presentation, whereas another BMMC subset expressing low levels of surface FcεRI and no detectable cell surface...
including proteins, glycans, lipids, and their chemically modified variations, are essential for the cell surface functions, e.g., extracellular signal sensing, extracellular matrix anchoring, and antigen presentation. In contrast, the contribution of nucleic acids particularly RNAs...
Immune checkpoint blockade (ICB) with PD-1/PD-L1 inhibition has revolutionized the treatment of non-small cell lung cancer (NSCLC). Durable responses, however, are observed only in a subpopulation of patients. Defective...
This phosphorylation, in conjunction with antigen presentation by an antigen-presenting cell (APC) to the extracellular domain of the TCR, results in recruitment of a second tyrosine kinase, ZAP70, to the complex via binding of the ZAP70 SH2 domains to the phosphorylated receptor. ZAP70 ...
ANTIGEN PRESENTATION In Immunology Guidebook, 2004 ANTIGEN-PRESENTING CELLS Antigen-presenting cells (APC) are cells that can process a protein antigen, break it into peptides, and present it in conjunction with class II MHC molecules on the cell surface where it may interact with appropriate T ...

consistent with our finding that most cell surface proteins targeted by B3GNT2 areN-glycosylated (Fig.4c, d). In the case of HLA-A2:NY-ESO-1 antibody binding, kifunensine further reduced binding, potentially because antigen presentation was disrupted (Supplementary Fig.9b). For T cell proteins...
By introducing the E430G mutation into the humanized Tspan26 monoclonal antibody, IgG1, and utilizing intermolecular Fc-Fc interactions upon binding to cell-surface antigens, more efficient formation of IgG hexamers is achieved. These modified antibodies exhibit stronger complement-dependent cytotoxicity ...
