Experimental Autoimmune Encephalomyelitis

Experimental autoimmune encephalomyelitis (EAE) was induced as described previously (Radbruch et al., 2016). Briefly, mice were immunized subcutaneously with 250 μg of MOG35–55 (Pepceuticals, United Kingdom) emulsified in CFA (BD Difco, Germany) and received 400 ng pertussis toxin (PTx, List Biological Laboratories, Inc.) intraperitoneally at the time of immunization and 48 h later. Intravital multi-photon microscopy was carried out at the peak of disease.
