Methamphetamine (METH)-use disorder (MUD) is a very serious, potentially lethal, biopsychosocial disease. Exposure to METH causes long-term changes to brain regions involved in reward processing and motivation, leading vulnerable individuals to engage in pathological drug-seeking and drug-taking behavior that can remain a lifelong struggle. It is crucial to elucidate underlying mechanisms by which exposure to METH leads to molecular neuroadaptive changes at transcriptional and translational levels. Changes in gene expression are controlled by post-translational modifications via chromatin remodeling. This review article focuses on the brain-region specific combinatorial or distinct epigenetic modifications that lead to METH-induced changes in gene expression.

Psychotropic stimulants like methamphetamine (METH) have an impact on the physiology, behavior, and psychology of human beings and can damage the reproductive and neuroendocrine systems in them. These deleterious impacts include a temporary drop in the relative weight of the testis along with adverse effects on spermatogenesis. Sambucus nigra, also known as elderberry (EB) or sweet elder, is a source of bioactive compounds that has drawn growing attention for its potential beneficial impact in preventing and treating several diseases.

Methamphetamine (METH), a synthetic stimulant, has seen an escalating abuse situation globally over the past decade. Although the molecular mechanism underlying METH-induced neurotoxicity has been explored, the dysfunction of brain-derived neurotrophic factor (BDNF) neuroprotection in the context of METH neurotoxicity remains insufficiently understood. Our previous studies have found that METH induced neurotoxicity and BDNF expression in rat primary neurons, necessitating further research into this paradox.

Methamphetamine (METH) is a synthetic drug with potent addictive, relapse, and neurotoxic properties. METH abuse contributes to severe damage to the central nervous system, potentially causing cognitive impairments, behavioral changes, and neurodegenerative diseases. METH-induced neuronal damage is closely related to apoptosis and cell cycle abnormalities, while gene expression regulator microRNAs (miRNAs) may play extensive roles in this progress, but the specific mechanisms remain unclear.

Co-exposure to methamphetamine (METH) abuse and HIV infection exacerbates central nervous system damage. However, the underlying mechanisms of this process remain poorly understood. This study aims to explore the roles of neuronal autophagy in the synergistic damage to the central nervous system caused by METH and HIV proteins.
