Bacopa monniera (CDRI-08)‎ Upregulates the Expression of Neuronal and Glial Plasticity Markers in the Brain of Scopolamine Induced Amnesic Mice

Abstract EN

Preclinical studies on animal models have discerned the antiamnesic and memory-enhancing potential of Bacopa monniera (Brahmi) crude extract and standardized extracts.

These studies primarily focus on behavioral consequences.

However, lack of information on molecular underpinnings has limited the clinical trials of the potent herb in human subjects.

In recent years, researchers highlight plasticity markers as molecular correlates of amnesia and being crucial to design therapeutic targets.

In the present report, we have investigated the effect of a special extract of B.

monniera (CDRI-08) on the expression of key neuronal (BDNF and Arc) and glial (GFAP) plasticity markers in the cerebrum of scopolamine induced amnesic mice.

Pre- and postadministration of CDRI-08 ameliorated amnesic effect of scopolamine by decreasing acetyl cholinesterase activity and drastically upregulating the mRNA and protein expression of BDNF, Arc, and GFAP in mouse cerebrum.

Interestingly, the plant extract per se elevated BDNF and Arc expression as compared to control but GFAP was unaltered.

In conclusion, our findings provide the first molecular evidence for antiamnesic potential of CDRI-08 via enhancement of both neuronal and glial plasticity markers.

Further investigations on detailed molecular pathways would encourage therapeutic application of the extract in memory disorders.
