Fig. 11: C16 in combination with Ang-1 treatment supressed the activated astrocytes.

a–l The activated astrocytes in the SN were stained with GFAP (green). C16 (c, h), Ang-1 (d, i), and especially the C + A treatment (e, j) suppressed the proliferation of astrocytes in vehicle-treated PD models (b, g). Panel k shows astrocytes in the normal control group. Panel l shows the proliferated glial cells and glial scar (red arrow in l) in the vehicle-treated group in high magnification. Scale bar = 100 µm. m Stereological analysis of GFAP + cells. a p < 0.05 versus the normal control group; b p < 0.05 versus the vehicle group; c p < 0.05 versus the C16-treated group; d p < 0.05 versus the Ang-1-treated group. GFAP, glial fibrillary acidic protein; C16, peptide (KAFDITYVRLKF) that can selectively bind integrin ανβ3; Ang-1 angiopoietin-1.
