The Arg1+Iba1+ cells were restricted to the demyelination lesion core and surrounded by other Iba1+ cells like CD86+Iba1+ cells at 10 dpi, consistent with the localization of CD206+Iba1+ and CD16/32+Iba1+ cells at 10 dpi (Fig. 8a, b). The gene discussed is CD86; the disease is Peripheral demyelination.
