Similarly, glycine transporters (GlyTs), an emerging drug target for psychiatric and other diseases, could control dendritic integration through ambient glycine levels. Both hypotheses were tested at dendrites of CA1 pyramidal cells in acute hippocampal slices by pharmacologically analysing how glycine, GlyTs and GlyRs change the postsynaptic response to local dendritic excitatory input. Using microiontophoretic glutamate application, we found that glycine can indeed significantly increase dendritic excitability and dendritic spiking. We also uncovered that GlyTs are powerful modulators of dendritic spiking, which can limit the impact of glycine sources on CA1 pyramidal cells. Our experiments also revealed that GlyRs can have an opposite, inhibitory effect on the slow dendritic spike component. This directly demonstrates that glycine can dynamically enhance dendritic responsiveness to local input and promote dendritic spiking, while GlyTs and GlyRs have an opposing effect.

However, its precise role in these pathologies remains incompletely understood. We investigated SST and SSTR expression across diverse brain cell types in control and TSC cortical samples using single-cell RNA sequencing (scRNA-seq). We conducted functional assessments of SST signaling using electrophysiological recordings in <em>Xenopus laevis</em> oocytes microtransplanted with human brain membranes. We pharmacologically modulated SST receptor activity to elucidate receptor-specific effects on GABAergic transmission. scRNA-seq analysis revealed that SST expression is predominantly confined to GABAergic interneurons, while SSTR1 and SSTR2 exhibit strong expression in both glutamatergic and GABAergic neuronal populations. In TSC samples, SSTR5 was upregulated in GABAergic neurons, SSTR2 in glutamatergic neurons, while SSTR3 was downregulated in both glutamatergic neurons and microglia. Functional experiments demonstrated that SST enhances GABAergic currents in control tissues through a receptor-mediated mechanism involving protein kinase C activation. In contrast, SST application in TSC samples resulted in a significant suppression of GABAergic currents. Pharmacological inhibition of SSTR3 further exacerbated this effect, suggesting a compensatory role for this receptor subtype.

We tested an alternative hypothesis that certain types of epileptiform activity, specifically high frequency oscillations (HFOs, defined as 250–500 Hz fast ripples), inhibit interictal spikes (IIS), which are currently used to assess hyperexcitability clinically. We recorded wideband (0.1–500 Hz) hippocampal local field potentials in three AD (Tg2576, Presenilin 2<sup>-/-</sup>, Ts65Dn Down syndrome model) and two epilepsy (intrahippocampal kainic acid, pilocarpine) mouse models during wakefulness and sleep.

However, IIS and HFOs showed divergent relationships: a negative correlation between their rates was observed only in AD, in contrast to a positive correlation in epilepsy. HFOs preceded IIS at much shorter intervals in epilepsy than in AD. Co-occurrence of IIS with ripples did not differ between AD and epilepsy. These findings reveal a novel dissociation between clinically-relevant EEG biomarkers in AD and epilepsy. In AD, HFOs may inhibit IIS, which could lead to underestimation of hyperexcitability and hinder patient stratification for anti-seizure therapies.

NMDA-induced iLTP in synapses formed by parvalbumin- (PV) positive INs on PCs was reduced to zero by SKF, while SCH converted iLTP to iLTD. Interestingly, NMDA-induced iLTP in the somatostatin- (SST) positive INs was reversed to iLTD by both SKF and SCH, while these compounds were ineffective on baseline activity, and these effects were mirrored by changes in gephyrin clusters. Thus, the impact of D1Rs on inhibitory plasticity observed at the SST INs and PCs showed differences with respect to baseline activity, NMDA-induced plasticity, and the kinetics of synaptic currents.
