Study: Antiepileptic medication induces homeostatic synaptic plasticity in pyramidal neurons of the adult human neocortex
show Abstracthide Abstract
Homeostatic synaptic plasticity serves to maintain neuronal function within a dynamic range, compensating for perturbations in network activity. While coordinated structural and functional changes at synaptic sites play a crucial role in adaptive processes, the specific regulatory mechanisms and biological relevance of homeostatic plasticity in the human brain warrant further investigation. In this study, we investigated the effects of neural network silencing, achieved through pharmacological inhibition of voltage-gated sodium channels or glutamatergic neurotransmission – common targets of antiepileptic medication – on functional and structural properties of murine and human cortical tissue. Using mouse entorhino-hippocampal tissue cultures, acute slices of adult mice, and human brain tissue, we characterize homeostatic synaptic plasticity across models, brain regions, and species. Our findings demonstrate local homeostatic synaptic plasticity in the adult human neocortex, highlighting the potential effects of antiepileptic medication in brain regions unaffected by the primary diseases, which might represent a mechanism for neuropsychiatric effects linked to these medications and increased seizure susceptibility upon discontinuation of antiepileptic medication. Overall design: Comparative gene expression profiling analysis of RNA-seq data in different brain regions across species to decipher the effects of pharmacological activity deprivation in neural circuits.

Construction protocol: For experiments in organotypic tissue cultures, 5-6 cultures of the same mouse were collected and used per sample. For in vivo experiments, the mPFC of treated and untreated adult mice was dissected and the mPFC of the left hemisphere was used as one sample. In experiments with human material, the tissue of each patient was seen as one biological sample. RNA was isolated using the Monarch® Total RNA Miniprep Kit (#T2010S; New England Biolabs) according to the manufacturer's instructions. RNA quantity and quality were assessed using an Agilent RNA 6000 Pico Kit (#5067-1513; Agilent) with a 2100 Bioanalyzer (#G2939BA; Agilent). After RNA isolation from TTX-treated tissue cultures, library preparation and RNA sequencing was performed using the genome sequencer Illumina HiSeq technology in NovaSeq 6000 S4 PE150 XP sequencing mode (service provided by Eurofins). After RNA isolation from the mPFC of mouse in vivo experiments and human neocortical samples, poly(A)- selection was performed using a poly(A)-selection mRNA magnetic isolation module (#E7490; New England Biolabs) according to the manufacturer's instructions. For non-directional library preparation, NEBNext Ultra II RNA Library Preparation Kit for Illumina (#E7770; New England Biolabs) was used. After fragmentation and adaptor ligation, dual index primers (New England Biolabs, #E7600S) were ligated in a library amplification step using 10 PCR cycles. Libraries were finally cleaned up with 0.8X SPRI beads following a standard bead purification protocol. Library purity and size distribution were assessed with a High Sensitivity DNA assay on a Bioanalyzer instrument (Agilent). We quantified the libraries using the NEBNext Library Quant Kit for Illumina (New England Biolabs, #E7630) based on the mean insert size provided by the Bioanalyzer. A 10 nM sequencing pool (120 µl in Tris-HCl, pH 8.5) was generated for sequencing on the NovaSeq6000 sequencing platform (Illumina; service provided by CeGaT GmbH, Tübingen, Germany). We performed a paired-end sequencing with 100 bp or 150 bp read length.
