The Notch signaling pathway is a highly conserved cell signaling system present in most animals. Mammals possess four different notch receptors, referred to as NOTCH1, NOTCH2, NOTCH3, and NOTCH4. The notch receptor is a single-pass transmembrane receptor protein. It is a hetero-oligomer composed of a large extracellular portion, which associates in a calcium-dependent, non-covalent interaction with a smaller piece of the notch protein composed of a short extracellular region, a single transmembrane-pass, and a small intracellular region.
Genetically engineered human trophoblast cells, methods of making and using the same
The present application belongs to the field of cell therapy and immunotherapy, and provides a genetically engineered human trophoblast, a preparation method and application thereof. The human trophoblast takes K562 cells as starting cells, and stably expresses membrane-bound interleukin 21, CD137 ligand and Delta-like ligand 1 after genetic engineering. The constructed K562 three-factor trophoblast can significantly improve the expansion efficiency, activation state and functional stability of NK cells and γδT cells. The synergistic mechanism includes enhancing the proliferation, cytotoxicity and stemness maintenance of NK cells and γδT cells through STAT3, NF-κB and Notch signaling pathways, respectively. The human trophoblast has the advantages of good expression stability, significant functional enhancement, and high activity after freezing and recovery.
