  • Combinatorial depletions of G-protein coupled receptor kinases in immune cells identify pleiotropic and cell type-specific functions

    Immune cells commonly express two to four members of the GRK family (GRK2, GRK3, GRK5, GRK6) simultaneously , but we have very limited knowledge about their interplay in primary immune cells. Together, our findings demonstrate the complexity of GRK functions in immune cells, which go beyond GPCR Furthermore, they highlight the need for studying GRK functions in primary immune cells to address their ; GRK; T cells; dendritic cells; immune cell trafficking; leukocytes; neutrophils.

  • High Metabolite Concentrations in Portal Venous Blood as a Possible Mechanism for Microbiota Effects on the Immune System, and Western Diseases
