Figure(s):Figure 1, 2, 3
Annotation description:Figure 1-3: Nogo-A (gene RTN4) inhibition through a specific antibody, as well as inhibition of its receptors NgR (gene RTN4R) and S1PR2, affects dendritic spine development in CA3 pyramidal neurons. Confocal imaging after application showed spine density and morphology was significantly affected. This was confirmed by FRAP of eGFP-actin in spines.

Figure 3: S1PR2 is internalized upon Nogo-A-Δ20 binding in 3T3 cells.

Figure 5: Nogo-A-Δ20 inhibition is mediated via the G13-LARG-RhoA signaling axis and can be modulated by exogenous S1P in 3T3 cells.
