[PDF][PDF] Neuronal BIN1 regulates presynaptic neurotransmitter release and memory consolidation

…, T Nomura, RJ Andrew, NY Masse, V Sampathkumar… - Cell reports, 2020 - cell.com
BIN1, a member of the BAR adaptor protein family, is a significant late-onset Alzheimer
disease risk factor. Here, we investigate BIN1 function in the brain using conditional knockout (…

Integration of signals from different cortical areas in higher order thalamic neurons

V Sampathkumar, A Miller-Hansen… - Proceedings of the …, 2021 - National Acad Sciences
Higher order thalamic neurons receive driving inputs from cortical layer 5 and project back
to the cortex, reflecting a transthalamic route for corticocortical communication. To determine …

Layer 5 of cortex innervates the thalamic reticular nucleus in mice

BJ Carroll, V Sampathkumar… - Proceedings of the …, 2022 - National Acad Sciences
Neurons in the thalamic reticular nucleus (TRN) are a primary source of inhibition to the dorsal
thalamus and, as they are innervated in part by the cortex, are a means of corticothalamic …

A lactotransferrin single nucleotide polymorphism demonstrates biological activity that can reduce susceptibility to caries

…, K Velliyagounder, V Sampathkumar… - Infection and …, 2013 - Am Soc Microbiol
Streptococcus mutans is prominently linked to dental caries. Saliva's influence on caries is
incompletely understood. Our goal was to identify a salivary protein with anti- S. mutans …

…, M Bendaoud, EA Izano, V Sampathkumar… - PLoS …, 2013 - journals.plos.org
Cell-free extracts isolated from colony biofilms of Actinobacillus pleuropneumoniae serotype
5 were found to inhibit biofilm formation by Staphylococcus aureus, S. epidermidis and …

[PDF][PDF] Regional cytoarchitecture of the adult and developing mouse enteric nervous system

R Hamnett, LB Dershowitz, V Sampathkumar, Z Wang… - Current Biology, 2022 - cell.com
The organization and cellular composition of tissues are key determinants of their biological
function. In the mammalian gastrointestinal (GI) tract, the enteric nervous system (ENS) …

[HTML][HTML] A three-dimensional thalamocortical dataset for characterizing brain heterogeneity

…, EC Johnson, JD Miano, V Sampathkumar… - Scientific Data, 2020 - nature.com
Neural microarchitecture is heterogeneous, varying both across and within brain regions.
The consistent identification of regions of interest is one of the most critical aspects in …

[HTML][HTML] Multi-modal imaging of a single mouse brain over five orders of magnitude of resolution

S Foxley, V Sampathkumar, V De Andrade, S Trinkle… - NeuroImage, 2021 - Elsevier
Mammalian neurons operate at length scales spanning six orders of magnitude; they
project millimeters to centimeters across brain regions, are composed of micrometer-scale-…

Distributed optimization for nonrigid nano-tomography

…, BJ Gould, Y Zhang, V Sampathkumar… - IEEE Transactions …, 2021 - ieeexplore.ieee.org
Resolution level and reconstruction quality in nano-computed tomography (nano-CT) are in
part limited by the stability of microscopes, because the magnitude of mechanical vibrations …

[HTML][HTML] Isochronic development of cortical synapses in primates and mice

G Wildenberg, H Li, V Sampathkumar… - Nature …, 2023 - nature.com
The neotenous, or delayed, development of primate neurons, particularly human ones, is
thought to underlie primate-specific abilities like cognition. We tested whether synaptic …
