Immunohistochemical analysis for macrophage markers Iba-1 a and MERTK b in control and ALS-CP postmortem tissues. Arrows in a and b point to macrophage localization at the base of the CP epithelial cells, while arrowheads in a point to stromal localization.Insert in a shows a highly branched morphology of an Iba1-positive cell. Arrowheads in b point to apical MERTK staining on the surface of CP epithelial cells, while inserts in b highlight staining on the apical surface of CP cells. Scale bars: 20 μm
