CBN Activated Stress-Protection and Brain-Plasticity Genes in Neuronal Cells

CBN had no negative impact on cell viability at concentrations from 5 to 100 micromolar. Transcriptomic analysis showed significant enrichment in Reactome pathways for cellular response to stress, cellular response to stimuli, and axon guidance. These findings suggest CBN may modulate neuronal cell survival and plasticity-related processes.

Differentiated NSC-34 neuroblastoma/spinal cord cells were pre-treated with CBN at five concentrations (5, 10, 20, 50, 100 micromolar) for 24 hours. Transcriptomic analysis via next-generation sequencing with pathway enrichment analysis using the Reactome database.

CBN is a minor cannabinoid that has received far less research attention than CBD or THC. This transcriptomic study identifies specific gene pathways through which CBN may exert neuroprotective effects, informing future research directions.

While these findings are strictly in vitro, they add to a growing body of evidence that minor cannabinoids may have distinct biological activities worth exploring. The axon guidance finding is particularly interesting for neurodegenerative disease research.

In vitro study using an immortalized cell line, not primary neurons. No disease model or functional readout beyond gene expression. Single timepoint (24 hours). Gene expression changes do not necessarily translate to protein-level or functional effects.
