  • Medigene will contribute its proprietary TCR discovery platform for the development of TCRs against multiple solid tumor targets nominated by BioNTech. (pressetext.com)
  • Individually, dendritic cells are extremely potent, but the problem is that they're not usually present in large enough quantities. (issels.com)
  • CD137 (4-1BB) is a member of the TNFR family that mediates potent T cell costimulatory signals upon ligation by CD137L or agonist monoclonal antibodies (mAbs). (unav.edu)
  • Importantly, T cells artificially expressing the MAGE-A3-Mp4 specific TCRs exhibited strong MAGE-A3+ tumor cell recognition and killing effect. (thno.org)
  • This work identified candidate TCRs potentially suitable for TCR-T design targeting HLA-A2 restricted MAGE-A3 tumor antigen. (thno.org)
  • The sale and licensing deal with BioNTech is an important validation from a global leading biotech company of our proprietary technologies to discover and characterize highly specific TCRs and empower resulting TCR-T cells to fight solid tumors. (pressetext.com)
  • Merkel cells are nondendritic, nonkeratinocytic epithelial cells located primarily in or near the basal layer of the epidermis. (medscape.com)
