  • Patent number: 11957673
    Abstract: Compositions and methods of selectively activating Akt3 are provided.
    Type: Grant
    Filed: September 6, 2018
    Date of Patent: April 16, 2024
    Assignee: AUGUSTA UNIVERSITY RESEARCH INSTITUTE, INC.
    Inventors: Samir Khleif, Mikayel Mkrtichyan
  • Publication number: 20240076379
    Abstract: Antibodies and antigen binding fragments thereof are provided that immunospecifically bind to PD-1, and induce or promote an immune response that activates immune cell proliferation or activity. Contrary to the existing paradigm that PD-1 exclusively promotes a suppressive immune response, the disclosed antibodies and antigen binding fragments thereof, immunospecifically bind to PD-1 and cause an activating signal to be delivered to the immune cell that activates the immune cell rather than suppressing the immune cell. In one embodiment, the disclosed antibodies and antigen binding fragments thereof specifically bind to PD-1 expressed on immune cells. The binding of the disclosed antibodies and antigen binding fragments thereof to PD-1 on immune cells causes an activating signal to be transmitted into the immune cell, for example a signal that enhances or promotes cytokine production and/or activation of immune cell proliferation.

  • Patent number: 11013735
    Abstract: Methods of selectively inhibiting Akt3 are provided. It has been discovered that 4-[(6-nitroquinolin-4-yl)amino]-N-[4-(pyridin-4-ylamino)phenyl]benzamide selectively inhibits Akt3. Because Akt3 modulates the suppressive function of natural Tregs and the polarization of induced Tregs, 4-[(6-nitroquinolin-4-yl)amino]-N-[4-(pyridin-4-ylamino)phenyl]benzamide can be used for modulating immune responses.
