CX3CR1 expression levels were significantly different (p < 0.0001) among the monocyte subsets, with classical monocytes having the lowest CX3CR1 MFI (342.0 ± 12.0), intermediate monocytes having intermediate CX3CR1 MFI (839.2 ± 25.6), and non-classical monocytes having the highest CX3CR1 MFI (1359 ± 28.0) (pooled data from individuals with and without T2DM). Here, CX3CR1 is linked to type 2 diabetes mellitus.
