Basket cells are inhibitory interneurons in cortical structures with the potential to efficiently control the activity of their postsynaptic partners. Although their contribution to higher order cognitive functions associated with the medial prefrontal cortex (mPFC) relies on the characteristics of their synaptic connections, the way that they are embedded into local circuits is still not fully uncovered. Here, we determined the synaptic properties of excitatory and inhibitory connections between pyramidal neurons (PNs), cholecystokinin-containing basket cells (CCKBCs) and parvalbumin-containing basket cells (PVBCs) in the mouse mPFC.

Advanced imaging of microorganisms, including protists, is challenging due to their small size. Specimen expansion prior to imaging is thus beneficial to increase resolution and cellular details. Here, we present a sample preparation workflow for improved observations of the single-celled eukaryotic pathogen Giardia intestinalis (Excavata, Metamonada).

Article Synopsis
  • Giardiasis, caused by the parasite Giardia intestinalis, poses treatment challenges due to metronidazole resistance, but no markers for this resistance have been identified yet.
  • This study examined 28 clinical samples from sub-assembly AII to assess variability in the flavohemoprotein gene's copy number, using digital PCR and next-generation sequencing, finding no link to metronidazole resistance.
  • Results showed significant genetic diversity across Giardia sub-assemblages, with aneuploidy contributing to genomic variability, highlighting the need for more research to find reliable resistance markers despite advances in CNV analysis methods.

Perisomatic inhibition profoundly controls neural function. However, the structural organization of inhibitory circuits giving rise to the perisomatic inhibition in the higher-order cortices is not completely known. Here, we performed a comprehensive analysis of those GABAergic cells in the medial prefrontal cortex (mPFC) that provide inputs onto the somata and proximal dendrites of pyramidal neurons.

(syn. ) is a widespread gastrointestinal protozoan parasite with debated taxonomic status. Currently, eight distinct genetic sub-groups, termed assemblages A-H, are defined based on a few genetic markers.
