WebbAβ-directed therapy decreased Aβ, concomitantly alleviated gliosis, cognitive impairment, and early—but not late—forms of tau-pathology [106] and synaptic deficits [107]. Clearance of soluble Aβ oligomeric forms, rather than amyloid plaques, were thereby associated with improved cognitive performance and synaptic plasticity deficits [47] . WebbThe particular class of TICT-active fluorophores called “molecular rotors” can enhance their fluorescence intensity in sterically restricted environments such as viscous media. 23 Viscous environments make TICT-active fluorophores unable to overcome potential barriers against 1 LE–TICT interconversions or, in some cases, viscosity hampers …
