GAL and neuroblastoma: In addition to moderate AChE inhibitory activity, GAL binds allosterically to α7 nAChR and prevents apoptosis induced by β-amyloid and thapsigargin—a specific α7 nAChR antagonist—through increasing the density of α7 nAChRs and expression of the antiapoptotic protein Bcl-2 in human neuroblastoma cell line SH-SY5Y [9].
