Esketamine, a newly developed antidepressant, is the subject of this research which seeks to explore its impact on depressive symptoms in neuropathic pain mice and the potential molecular mechanisms involved. Through transcriptome sequencing and bioinformatics analysis combined with in vivo studies, it was identified that esketamine markedly boosts the levels of the m6A methyltransferase METTL3 and the AMPA receptor GluA1 subunit. Esketamine activates METTL3, allowing it to bind with GluA1 mRNA, promoting m6A modification, thereby enhancing GluA1 expression at synapses.

Predicting disease trajectories in patients with major depressive disorder (MDD) can allow designing personalized therapeutic strategies. In this study, we aimed to show that measuring patients' plasticity - that is the susceptibility to modify the mental state - identifies at baseline who will recover, anticipating the time to transition to wellbeing. We conducted a secondary analysis in two randomized clinical trials, STAR*D and CO-MED.

Drug-induced rhabdomyolysis has become increasingly prevalent due to the rising use of medications such as statins, antidepressants, and antipsychotics. These can lead to muscle cell destruction and the release of myoglobin, potentially causing kidney damage. Recent advancements include the use of CytoSorb hemoadsorption as a promising therapy to remove myoglobin and other potentially toxic substances from the bloodstream.

Ethnopharmacological Relevance: Jieyu I Formula (JY-I) is an improved version of the classic formula "Sini San" documented in the books Shanghan Lun, which is known for regulating the liver and treating depression. However, the disturbance of neuronal signal transmission in the neural circuit of the brain is closely related to the occurrence of depression, yet its neural mechanism is still unclear.
Aim Of The Study: This study aimed to observe the antidepressant effect of JY-I on depressed mice induced by lipopolysaccharide and its underlying central nervous system mechanisms, focusing on the prefrontal cortex (PFC) to lateral habenular nucleus (LHb) neural circuit in the depressed mice model.
Esketamine at a Clinical Dose Attenuates Cerebral Ischemia/Reperfusion Injury by Inhibiting AKT Signaling Pathway to Facilitate Microglia M2 Polarization and Autophagy.

Purpose: This study aimed to assess the protective effect of a clinical dose esketamine on cerebral ischemia/reperfusion (I/R) injury and to reveal the potential mechanisms associated with microglial polarization and autophagy.
Methods: Experimental cerebral ischemia was induced by middle cerebral artery occlusion (MCAO) in adult rats and simulated by oxygen-glucose deprivation (OGD) in BV-2 microglial cells. Neurological and sensorimotor function, cerebral infarct volume, histopathological changes, mitochondrial morphological changes, and apoptosis of ischemic brain tissues were assessed in the presence or absence of esketamine and the autophagy inducer rapamycin.
