IL-22 and IL-22R1 are expressed in human brain. IL-22, IL-22R1, GFAP, and Caveolin-1 immunohistochemistry peroxidase stainings of brain tissue sections of control (a) and MS (bd) patients. MOG and HE stainings were used to detect MS demyelinating plaques (d). All four pictures belonging to one column (a, b, c, or d) were always immediately adjacent to each other. Pictures a, b, and c were taken at areas at the border between GM and NAWM, whereas pictures in d were taken from the same location at the edge between NAWM and a plaque. Inserts in columns a and b represent a threefold magnification of the selected area. Arrow: astrocyte-like pattern. a study patient B-C2, b and d study patient B-MS3, c study patient B-MS5 (Table 2). Scale bar, 50 μm (a, b: ×20, c, d ×40). GM: gray matter, NAWM: normal appearing white matter, WM: white matter. Representative pictures obtained from the observations of seven control and five MS autopsy samples
