Relative logarithmic expression (RLE) of P2XRs in MCs, astrocytes, and oligodendrocytes. P2XR RLE expression in skin MCs [142], cerebellum and cortex astrocyte and oligodendrocyte precursors [143] was obtained using Fantom 5 and compared to cell types with the highest RLE for a given receptor.

Gene	MCs	Astrocytes		Oligodendrocytes	Cell Types/Tissues with Highest RLE
	Skin (n = 4)	Cerebellum (n = 3)	Cortex (n = 3)	Precursors (n = 1)
P2X1	337.186	3.017	3.345	1.692	337.186 (MCs)
P2X2	0.032	0	0	0	15.242 (Seminal vesicle)
P2X3	25.120	67.947	96.481	51.310	282.548 (Smooth muscle cells)
P2X4	27.792	6.232	4.140	6.202	679.838(CD14+ monocytes)
P2X5	71.924	363.640	0.814	294.329	2237.838 (Bronchial epithelial cells)
P2X6	2.373	1.187	65.063	0	25.101(Cerebellum)
