Neuroprotective Action

The ginsenoside Rg1 exerts a neuroprotective effect during cerebral ischemia/reperfusion injury. Rg1 has been previously reported to improve PPARγexpression and signaling, consequently enhancing its regulatory processes. Due to PPARγ’s role in the suppression of oxidative stress and inflammation, Rg1’s PPARγ-normalizing capacity may play a role in the observed neuroprotective action of Rg1 during ischemic brain injury. We utilized a middle cerebral artery ischemia/reperfusion injury model in rats in addition to an oxygen glucose deprivation model in cortical neurons to elucidate the mechanisms underlying the neuroprotective effects of Rg1. We found that Rg1 significantly increased PPARγexpression and reduced multiple indicators of oxidative stress and inflammation. Ultimately, Rg1 treatment improved neurological function and diminished brain edema, indicating that Rg1 may exert its neuroprotective action on cerebral ischemia/reperfusion injury through the activation of PPARγsignaling. In addition, the present findings suggested that Rg1 was a potent PPARγagonist in that it upregulated PPARγexpression and was inhibited by GW9662, a selective PPARγantagonist. These findings expand our previous understanding of the molecular basis of the therapeutic action of Rg1 in cerebral ischemic injury, laying the ground work for expanded study and clinical optimization of the compound.

Neuroprotective Action

Neurodegeneration is closely linked to neuroinflammation. It is often associated with oxidative stress and meaningful changes in cell energy metabolism. Neuroinflammation is due to non-neuronal cell activation (microglia, astrocytes, mast cells) activation and proliferation. Also, it is associated with pro-inflammatory substances release, able to modify synaptic plasticity. Microglia and astrocytes activation lead to toxic agent’s release (reactive oxygen species, inflammatory cytokines); however, the final target of this process is the cholinergic neuron. A number of substances can promote neuroprotection; recent scientific evidence focuses on the role of sirtuins. In particular, SIRT1 is activated by caloric restriction, NAD biosynthesis and different activators, called STACs (Sirtuin Activating Compounds). Citicoline is one of the most powerful STACs. It has been widely shown to possess neuroprotective action, and lots of studies strengthened its possible role.
