Fig. 7From: Low-level blast exposure induces chronic vascular remodeling, perivascular astrocytic degeneration and vascular-associated neuroinflammationPerivascular apoptosis in a vessel with enlarged paravascular spaces. A hypothalamic vessel showing perivascular astrocytes (a, GFAP, red) and microglia (b, Iba1, magenta) analyzed by TUNEL staining (c, green), merged d. DAPI (blue). (*) denotes the enlarged paravascular spaces. TUNEL staining of perivascular astrocytes and of astrocyte-associated microglia is indicated by arrows. Scale bar, 25 µm a–dBack to article page
