  • Publication number: 20250082740
    Abstract: The disclosure relates to the field of molecular biology, and in particular relates to the use of CXCL 14. According to the present invention, different antigen proteins are transferred to the surface of a DC cell by means of the chemotactic binding capacity of CXCL 14 and surface receptors of immune cells such as DC cells. A chemokine of CXCL14 can effectively induce the binding of an antigen molecule to a specific immune cell at the N-terminal of an antigen protein, such that the cross presentation effect of the antigen molecule is greatly enhanced, and CXCL14 can finally induce a stronger specific immune response of the antigen molecule.

  • Publication number: 20250049916
    Abstract: The chemotactic binding ability of CCL13 and an immune cell surface receptor such as DC cells is used to transport different antigenic proteins to the surface of the DC cells, the efficiency of phagocytosis, processing, and presentation of various antigenic proteins by the DC cells is improved, and the effect of preventing and treating related diseases of the antigenic proteins is enhanced. A T2 sequence is further added in an antigen, such that the immune effect can be enhanced.

  • Patent number: 12029776
    Abstract: The present invention relates to the field of medical technology, in particular to a composition for treating cancer and use and medicament thereof. The composition comprises an SGLT1 inhibitor and a VEGFR2 inhibitor. The present invention finds that SGLT1 interacts with VEGFR2 to promote the development and progression of tumors; the present invention also finds that a composition of a VEGFR2 targeting inhibitor and an SGLT1 inhibitor has a synergistic anti-tumor effect, and the composition of the VEGFR2 targeting inhibitor and the SGLT1 targeting inhibitor can be used in cancer treatment.

  • Patent number: 12018278
    Abstract: Provided are chemical inducers of lineage reprogramming (CiLR) which include glycogen synthase kinase inhibitors, TGF? receptor inhibitors, cyclic AMP agonists or histone acetylators. Also provided is a method of inducing lineage reprograming in a partially or completely differentiated cell of a first type into a cell with characteristics of a second and different lineage. The method includes: contacting a cell with the CiLR for a sufficient period of time to result in reprograming the cell into a modified XEN-like cell which is subsequently programmed into a cell with characteristics of a second and different lineage.
