Cannabinoids Δ9-tetrahydrocannabinol and cannabidiol may be effective against methamphetamine induced mitochondrial dysfunction and inflammation by modulation of Toll-like type-4(Toll-like 4) receptors and NF-κB signaling.

Medical Hypotheses“The neurodegeneration, neuro-inflammation and mitochondrial dysfunction which occur by methamphetamine (METH) abuse or administration are serious and motivation therapeutic approaches for inhibition of these types of neurodegeneration. As we know, METH through Toll-like receptors (TLRs), specially type 4, and NF-κB signaling pathway causes neuro-inflammation and mitochondrial dysfunction.

Neuroprotective approach for management of METH-induced neurodegeneration, inflammation and mitochondrial dysfunction, through a novel neuroprotective agent is continuously being superior to any kind of other therapeutic strategy. Therefore, the clarification, introduction and development of efficacious novel neuroprotective agent are demanded. During recent years, using new neuroprotective agent with therapeutic probability for treatment of METH-induced neuro-inflammation and mitochondrial dysfunction has been astoundingly increased.

Previous studies have stated the neuroprotective and anti-inflammatory roles of cannabinoid derivate such as cannabidiol (CBD) and delta-9-tetrahydrocannabinol (Δ9-THC) in multiple neurodegenerative events and diseases.

According to literature cannabinoid derivate, by inhibition of TLR4 and activation of NF-κB signaling pathway, exerts their anti-inflammatory and neuroprotective effects and cause mitochondrial biogenesis. Thus we hypothesized that by using cannabinoids in METH dependent subject it would provide neuroprotection against METH-induced neurodegeneration, neuro-inflammation and mitochondrial dysfunction and probably can manage sequels of METH-induced neurochemical abuses via modulation of TLR4/NF-κB signaling pathway.

In this article, we tried to discuss our hypothesis regarding the possible role of CBD and Δ9-THC, as a potent neuroprotective and anti-inflammatory agents, in inhibition or treatment of METH-induced neurodegeneration, neuro-inflammation and mitochondrial dysfunction through its effects on TLR4/NF-κB signaling pathway.”
