Pacemaker translocations and power laws in 2D stem cell-derived cardiomyocyte cultures.

Power laws are of interest to several scientific disciplines because they can provide important information about the underlying dynamics (e.g. scale invariance and self-similarity) of a given system.

TAK1 inhibition in mouse astrocyte cultures ameliorates cytokine-induced chemokine production and neutrophil migration.

Systemic inflammation can exacerbate symptoms of many neurological diseases. This effect may be facilitated by glial cells of the central nervous system (CNS) that alter their transcriptional responses and up-regulate cytokine and chemokine expression which can, in turn trigger immune surveillance. In this study, we sought to determine the effects of pro-inflammatory cytokine stimulation (TNF, IL-1α, IL-1β) on astrocyte and microglia chemokine secretion.

HFD refeeding in mice after fasting impairs learning by activating caspase-1 in the brain.

Background: Diets that include some aspect of fasting have dramatically increased in popularity. In addition, fasting reduces inflammasome activity in the brain while improving learning. Here, we examine the impact of refeeding a low-fat diet (LFD) or high-fat diet (HFD) after fasting.

Indoleamine 2,3-dioxygenase 1 deletion promotes Theiler's virus-induced seizures in C57BL/6J mice.

Objective: Viral encephalitis increases the risk for developing seizures and epilepsy. Indoleamine 2,3-dioxygenase 1 (Ido1) is induced by inflammatory cytokines and functions to metabolize tryptophan to kynurenine. Kynurenine can be further metabolized to produce kynurenic acid and the N-methyl-d-aspartate receptor agonist quinolinic acid (QuinA).
