Epigenetic profiles of response to transcranial magnetic stimulation in treatment resistant depression

ABSTRACT: Peripheral blood DNA methylation was profiled in 46 patients with treatment-resistant depression prior to treatment with transcranial magnetic stimulation (TMS). Genome-wide DNA methylation was measured using the Illumina Infinium MethylationEPIC BeadChip (850K array). Following quality control, data from 46 subjects were included in downstream analyses. Treatment outcomes were assessed using the PHQ-9 depression scale and included treatment response (≥50% reduction in PHQ-9), symptom trajectory (ΔPHQ-9), and remission (PHQ-9 score < 5). Methylation data were analyzed to identify differentially methylated regions (DMRs) associated with treatment outcomes. Both raw IDAT files and processed beta-value data are provided.

Transcriptional changes in the rat brain induced by repetitive transcranial magnetic stimulation (rTMS)_IN_VITRO

Project description:Transcranial Magnetic Stimulation (TMS) is a noninvasive technique that uses pulsed magnetic fields to affect the physiology of the brain and central nervous system. Repetitive TMS (rTMS) has been used in the study and treatment of neurological conditions including major depression, stroke, epilepsy, schizophrenia, multiple sclerosis, Parkinson’s, and Alzheimer’s disease, as well as other, non-neurological disorders. Among the effects of rTMS, low-frequency protocols (≤ 1Hz) are generally understood to result in cortical inhibition, whereas high-frequency protocols (≥ 3Hz) increase cortical excitability. However, the complex molecular basis of rTMS is largely unexplored. Using three complementary rat models, in vitro, ex vivo, and in vivo, we show complex patterns of hippocampal and neocortical transcriptional response to stimulation in glutamatergic and GABAergic signaling pathways, as well as multiple inflammatory pathways, among others. This broad-based molecular survey helps provide a foundation to tease out the complex molecular mechanisms of the effects of rTMS.

Transcranial ultrasound stimulation ameliorates DSS-induced colitis and behavioral disorders by suppressing the inflammatory response in the brain

Project description:This study explores the efficacy of transcranial ultrasound stimulation (TUS) in mitigating dextran sulfate sodium (DSS)-induced colitis and associated behavioral abnormalities in mice. TUS treatment significantly reduced colon inflammation and tissue damage while improving histological scores. Additionally, TUS alleviated anxiety- and depression-like behaviors, possibly by suppressing neuroinflammation via the downregulation of pro-inflammatory cytokines in both the colon and the brain. These findings suggest TUS as a promising non-invasive therapy for managing gut inflammation and associated behavioral disorders, highlighting its potential clinical implications.

Cortical and hippocampal gene expression after transcranial focal stimulation and a single seizure in rats

Project description:Transcranial Electrical Stimulation has therapeutic effects on different diseases, including epilepsy. Particularly, Transcranial Focal Stimulation (TFS) has anticonvulsive and antiepileptogenic effects. Nevertheless, the mechanisms and therapeutic targets that induced these effects remain ellusive. We aimed to screen the genetic expression in the cerebral cortex and the hippocampus of rats after a single seizure and TFS to identify potential targets.

Transcriptional changes in PC12 cells induced by repetitive transcranial magnetic stimulation (rTMS) in MSCs-inhibited inflammatory conditions

Project description:Neuronal death is the primary cause of poor outcomes in cerebral ischemia. The Inflammatory infiltration in the early phase of ischemic stroke plays a vital role in triggering neuronal death. Either transplantation of mesenchymal stem cells (MSCs) derived from humans or repetitive transcranial magnetic stimulation (rTMS) have respectively proved to be neuroprotective and anti-inflammatory in cerebral ischemia. However, either treatment above has its limitations. Whether these two therapies have synergistic effects on improving neurological function and the underlying mechanisms remains unclear.Using an in vitro model of PC12 nerve cell co-culture with MSCs, we demonstrated a transcriptional response pattern, including REST, in which rTMS inhibited PANoptosis of PC12 cells in a low-inflammation environment induced by MSCs. This molecular investigation is helpful in providing a basis for sorting out the complex molecular mechanism of combination of rTMS and MSCs in treating ischemic stroke.

Transcranial current stimulation in the sensorimotor cortex of rats alters the expression of immune-mediating genes

Project description:Transcranial direct current stimulation (tDCS) has been applied in experimental and clinical settings for more than twenty years and may facilitate rehabilitation after stroke as suggested by clinical data (Hummel et al. 2005, Sparing et al. 2009). Intriguingly, tDCS evokes various cellular effects exceeding its primary neurophysiological actions: We previously described subacute effects of tDCS on immune- and stem cells in the rat brain (Rueger et al. 2012, Keuters et al. 2015, Pikhovych et al. 2016, Braun et al. 2016). However, the effects of tDCS on immune-mediating genes have not yet been investigated. To investigate the more immediate effects of tDCS regulating those cellular responses, we treated rats with a single session of either anodal or cathodal tDCS, and analyzed the gene expression by microarray; sham-stimulated rats served as control. We confirmed the effects of gene upregulation by immunohistochemistry at the protein level. We here report for the first time that acute anodal transcranial direct current stimulation enhanced the expression of several genes coding for MHC-I, affecting inflammation and synaptic plasticity (Neumann et al. 1995, Shatz et al. 2009). Moreover, cathodal tDCS increased expression of the gene encoding for the immunoregulatory protein Osteopontin. Osteopontin has beneficial effects on neural stem cells and microglia after brain damage such as stroke (Rabenstein et al. 2015, Rabenstein et al. 2016, Ladwig et al. 2017, Rogall et al. 2017). Overall, our data indicate that a specific modulation of neuroinflammatory processes by non-invasive brain stimulation constitutes a promising therapeutic option with immediate translational relevance.

Cortical and hippocampal gene expression after transcranial focal stimulation in healthy rats

Project description:Transcranial Electrical Stimulation has therapeutic effects on different diseases, including epilepsy. Nevertheless, previous evidence also suggest that TFS could modify protein expression in the healthy brain of rats. We aimed to screen genetic expression in the cerebral cortex and the hippocampus of healthy rats to identify potential targets of therapeutic or adverse effects of TFS.
