Environment-dependent modulation of synaptic components in the Drosophila visual and MB circuits. a Modulation of active zone components upon prolonged exposure to light. In constant darkness (DD) or in a light/dark cycle (LD), the divergent canonical Wnt pathway stabilizes the active zone structure. Constant light (LL) suppresses the divergent canonical Wnt pathway, leading to delocalization of BRP, DLiprin-α, and DRBP from active zone. Cryptochrome (Cry) forms a complex with BRP under light exposure. b Age-related structural changes in synapses of MB calyx. Ageing induces a consistent enlargement of the AZ associated with an increased number of BRP molecules
