Constitutive activity of the cation channel TRPM8 regulates the function and differentiation of human monocytes
Ontology highlight
ABSTRACT: This study investigated the impact of TRPM8 activity on human monocyte differentiation and function. CD14+ peripheral blood monocytes were isolated from healthy volunteers and differentiated into macrophages using M-CSF, in the presence or absence of 10μM AMTB (TRPM8 antagonist). RNA seq was performed on CD14+ monocytes and macrophages differentiated in vehicle(Mo-M-DMSO) or AMTB (Mo-M-AMTB). To assess the transcriptional changes that normally occur in monocyte to macrophage differentiaiton we compared the Mo-M-DMSO and CD14+ monocyte samples. 3109 genes were significantly down-regulated and 3403 up-regulated in Mo-M-DMSO samples compared to CD14+ monocytes. To investigate the impact of AMTB upon macrophage differentiation we compared the Mo-M-DMSO and Mo-M-AMTB. 556 genes were significantly lower and 421 genes were significantly higher in Mo-M-AMTB samples compared to Mo-M-DMSO samples. 331 out of the 556 genes lower in Mo-M-AMTB samples were genes that were normally up-regulated during differentiaiton and 253 out of the 421 genes higher in the Mo-M-AMTB samples were genes that were normally down-regulated during differentiation indicating that AMTB predominantly acts to inhibit aspects of the differentiation programme.
