  • Patent number: 11826403
    Abstract: The present invention relates to the identification of ALMS1 as the missing player involved in the regulation of the insulin-mediated glucose uptake through GLUT4 sorting vesicles, and to the down-regulation of ALMS1 by ?PKC. Accordingly, the present invention relates to a molecule capable of preventing the binding of ?PKC on ALMS1 for use for treating or preventing diabetes, in particular type 2 diabetes. In addition, the present invention relates to a method for identifying molecule capable of preventing the binding of ?PKC on ALMS1.

  • Patent number: 11623004
    Abstract: Disclosed herein are compositions for vaccination against respiratory syncytial virus (RSV) comprising a RSV F polypeptide stabilized in a prefusion conformation and an inulin adjuvant. Also disclosed herein are methods of vaccinating a subject against a respiratory syncytial virus (RSV) infection comprising administering to the subject an RSV F polypeptide stabilized in a prefusion conformation and an inulin adjuvant. In some embodiments, the subject is a female, and the method can reduce RSV infection in the subject and/or in the offspring of the subject. In some embodiments, the method decreases vaccine-enhanced respiratory disease (VERD) and/or eosinophilia in the subject or offspring of the subject.

  • Publication number: 20230102159
    Abstract: An immunogen useful for treating malaria generally includes an immunogenic carrier and an antigenic malaria circumsporozoite protein (CSP) peptide that includes the peptide NANPNVDPNANPNVD (SEQ ID NO:2) linked to the immunogenic carrier. The immunogen may be administered to a subject having or at risk of having malaria. Alternatively, the immunogen may be administered to an individual having or at risk of having Plasmodium falciparum blood stage parasitemia. In some cases, the immunogen can be administered in combination with another therapeutic agent for treating malaria of Plasmodium falciparum blood stage parasitemia.
