As far as it concerns the macrophages, which are also present at the inflammatory loci during the acute and chronic phase of our experimental model of MS, they are described here for the first time to co-localize with NGF (26.6 ± 2.7, p < 0.0001, and 19 ± 2.6, p < 0.0001, respectively) (Fig. 5m–o). Here, NGF is linked to myeloid sarcoma.
