Standing genetic variation and chromosome differences drove rapid ecotype formation in a major malaria vector

Kavli Affiliate: Scott Small | Authors: Scott T Small, Carlo Costantini, N’Fale Sagnon, Moussa W Guelbeogo, Scott J Emrich, Andrew D Kern, Michael C Fontaine and Nora J Besansky | Summary: Abstract Local adaptation results in the formation of ecotypes–conspecific groups with heritable differences that increase fitness to distinct environments. The adaptive significance of ecotypes […]

Contribution of protein conformational heterogeneity to NMR lineshapes at cryogenic temperatures

Kavli Affiliate: Ann McDermott | Authors: Xu Yi, Keith Fritzsching, Rivkah Rogawski, Yunyao Xu and Ann E McDermott | Summary: While low temperature NMR holds great promise for the analysis of unstable samples and for sensitizing NMR detection, spectral broadening in frozen protein samples is a common experimental challenge. One hypothesis explaining the additional linewidth […]

Predicted and Experimental NMR Chemical Shifts at Variable Temperatures: The Effect of Protein Conformational Dynamics

Kavli Affiliate: Ann McDermott | Authors: Xu Yi, Lichirui Zhang, Richard Friesner and Ann E McDermott | Summary: NMR chemical shifts provide a sensitive probe of protein structure and dynamics. Prediction of shifts, and therefore interpretation of shifts, particularly for the frequently measured amidic 15N sites, remains a tall challenge. We demonstrate that protein 15N […]

Zinc Alters the Supramolecular Organization of Nucleic Acid Complexes with Full-Length TIA1

Kavli Affiliate: Ann McDermott | Authors: Yizhuo Yang, Keith Fritzsching, Sasha He and Ann E McDermott | Summary: T-Cell Intracellular Antigen-1 (TIA1) is a 43 kDa multi-domain RNA-binding protein involved in stress granule formation during eukaryotic stress response, and has been implicated in neurodegenerative diseases including Welander distal myopathy and amyotrophic lateral sclerosis. TIA1 contains […]

Common rules underlying optogenetic and behavioral modulation of responses in multi-cell-type V1 circuits

Kavli Affiliate: Kenneth Miller | Authors: Agostina Palmigiano, Francesco Fumarola, Daniel P. Mossing, Nataliya Kraynyukova, Hillel Adesnik and Kenneth Miller | Summary: The visual cortex receives non-sensory inputs containing behavioral and brain state information. Here we propose a parallel between optogenetic and behavioral modulations of activity and characterize their impact on cell-type-specific V1 processing under […]

Hippocampal area CA2 controls seizure dynamics, interictal EEG abnormalities and social comorbidity in mouse models of temporal lobe epilepsy

Kavli Affiliate: Steven Siegelbaum | Authors: Christos Panagiotis Lisgaras, Azahara Oliva, Sam Mckenzie, John LaFrancois, Steven A. Siegelbaum and Helen E. Scharman | Summary: Temporal lobe epilepsy (TLE) is characterized by spontaneous recurrent seizures, abnormal activity between seizures, and impaired behavior. CA2 pyramidal neurons (PNs) are potentially important because inhibiting them with a chemogenetic approach […]

Adult born hippocampal granule cells promote pattern separation by bidirectionally modulating the remapping of place and cue cells

Kavli Affiliate: Rene Hen | Authors: Sebnem N. Tuncdemir, Andres D. Grosmark, Hannah Chung, Victor M. Luna, Clay O. Lacefield, Attila Losonczy and Rene Hen | Summary: Abstract The hippocampal dentate gyrus (DG) exhibits a unique form of neural plasticity that results from continuous integration of adult born neurons, referred to as ‘adult neurogenesis’. Recent […]

Direct Cortical Inputs to Hippocampal Area CA1 Transmit Complementary Signals for Goal-directed Navigation

Kavli Affiliate: Attila Losonczy | Authors: John C Bowler and Attila Losonczy | Summary: Summary The entorhinal cortex (EC) is central to the brain’s navigation system. Its subregions are conventionally thought to compute dichotomous representations for spatial processing: medial entorhinal cortex (MEC) provides a global spatial map, while lateral entorhinal cortex (LEC) encodes specific sensory […]

The HCN1 hyperpolarization-activated cyclic nucleotide-gated channel enhances evoked GABA release from parvalbumin positive interneurons

Kavli Affiliate: Steven Siegelbaum | Authors: Tobias Bock, Eric W Buss, Olivia M Lofaro, Felix W Leroy, Bina Santoro and Steven A Siegelbaum | Summary: Abstract Hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels generate the cationic Ih current in neurons and regulate the excitability of neuronal networks. The function of HCN channels depends, in part, on their […]
