    Abstract: An agent selected from A/B-cis furostane, furostene, spirostane and spirostene steroidal sapogenins and ester, ether, ketone and glycosylated forms thereof is used to induce self-regulated homeostasis of neurotrophic factors (NFs), for example BDNF and/or GDNF, NFs with limited and manageable side effects in a subject, by modulating NFs in a non-toxic manner under homeostatic control.
