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.

Herein we propose a model for immune conditioning, whereby metabolites such as butyrate affect immune cells as they pass through the portal venous system. Deficiency of SCFA would lead to pro-inflammatory immune cell skewing through insufficient G-protein Such pro-inflammatory immune cells may travel to tissues such as the brain, the lung, the kidney etc This model helps explain how the gut microbiome may be affecting peripheral immune cells, and consequently
