  • Patent number: 11364219
    Abstract: The present invention relates to the treatment of microbiome dysregulations. Said dysregulations may subsequently contribute to the development of several chronic diseases. Thus characterization of new post-biotic compounds inducing beneficial changes on host-microbiota interactions may be highly desirable. The inventors showed that Nlrp6 diurnally coordinates cyclical adaptation of the gut microbiota diversity to epithelial plasticity in response to a treatment with a Csnk2 inhibitor. The invention therefore relates to an inhibitor of Csnk2, for use in the treatment of microbiome dysregulations notably associated with circadian clock disruption. Said inhibitor may be selected among chemically synthesized or natural selective Csnk2 inhibitors such as flavones.

  • Publication number: 20220117960
    Abstract: The success of anti-tumor immune responses requires effector T cells to infiltrate solid tumors, a process guided by chemokines. Herein, we demonstrate that in vivo post-translational processing of chemokines by dipeptidylpeptidase 4 (DPP4, also known as CD26) limits lymphocyte migration to sites of inflammation and tumors. Inhibition of DPP4 enzymatic activity enhanced tumor rejection by preserving biologically active CXCL10, and increasing trafficking into the tumor by lymphocytes expressing the counter-receptor CXCR3. Furthermore, DPP4 inhibition improved adjuvant-based immunotherapy, adoptive T cell transfer and checkpoint blockade. These findings provide the first direct in vivo evidence for controlling lymphocyte trafficking through CXCL10 cleavage and support the use of DPP4 inhibitors for stabilizing the biologically active form of chemokines as a strategy to enhance tumor immunotherapy.
