  • Publication number: 20200276190
    Abstract: GPR174 is an orphan receptor that has been implicated in cancer, nervous system diseases and disorders and neuroregeneration. We have identified inhibitors of GPR174 and have identified the G-protein signaling pathways that GPR174 modulates. Based on this discovery, the present invention features methods for inhibiting GPR174 activity and thereby stimulating an immune response in a subject in need thereof, particularly in the use of treatment of non-malignant neoplasms, malignant neoplasms (i.e., cancer), nervous system diseases and disorders and neuroregeneration, as well as related compositions.

  • Publication number: 20200157245
    Abstract: In one aspect, the invention provides methods of inhibiting the effects of MASP-2-dependent complement activation in a living subject. The methods comprise the step of administering, to a subject in need thereof, an amount of a MASP-2 inhibitory agent effective to inhibit MASP-2-dependent complement activation. In some embodiments, the MASP-2 inhibitory agent inhibits cellular injury associated with MASP-2-mediated alternative complement pathway activation, while leaving the classical (C1q-dependent) pathway component of the immune system intact. In another aspect, the invention provides compositions for inhibiting the effects of lectin-dependent complement activation, comprising a therapeutically effective amount of a MASP-2 inhibitory agent and a pharmaceutically acceptable carrier.
