Following publication of the original article [1], the author noticed that Figs. 6 and 7 of the published version of this article were incorrectly uploaded. Presented here are the corrected Figs. 6 and  7.

Fig. 6

CCL2-induced microglial activation may aggravate neuronal apoptosis. A, B Western blotting detection of IL-1Ra protein expression in spinal cord tissue. C Immunofluorescence detection of IL-1Ra protein expression in neuronal cells

Fig. 7

The CCR2 antagonist INCB3344 decreases microglial activation and neuronal apoptosis after SCI. A–H ELISA, qRT-PCR and western blotting evaluation of spinal cord TNF-α, IL-1β and IL-6 expression. I Immunofluorescence staining to detect the expression of the microglial activation marker OX42. J, K TUNEL staining to detect spinal cord apoptosis. L, M Western blotting to detect spinal cord apoptosis related protein expression
