Vagus nerve stimulation (VNS) has been shown to limit immune cell activity across several pathologies ranging from sepsis to auto-immune diseases. While stimulation of vagal efferent neurons has been previously demonstrated to reduce maladaptive host responses during endotoxemia, only selective stimulation of vagal afferent neurons was able to inhibit TLR7-induced macrophage activation and neutrophil recruitment in the lung. These anti-inflammatory actions are facilitated by systemic increases in epinephrine, as VNS significantly increased epinephrine in the serum and bronchoalveolar lavage fluid, and inhibition of epinephrine production eliminated the protection afforded by VNS.

In horses, this condition can increase the risk of life-threatening hyperthermia. A prior study has suggested that equine anhidrosis is associated with a missense variant (rs68643109) in the Potassium Voltage-Gated Channel Subfamily E Regulatory Subunit 4 (KCNE4) gene.

ICC along the submucosal border (ICC-SM) contribute to mixing and more complex patterns of colonic motility. We show the complex patterns of Ca signaling in ICC-SM and the relationship between ICC-SM Ca transients and activation of smooth muscle cells (SMCs) using optogenetic tools.

To analyze these datasets, spatio-temporal maps (STMaps) that allow for 2D visualization of Ca signals as a function of time and space are often used. Methods of STMap analysis rely on a highly arduous process of user defined segmentation and event-based data retrieval.

We search four scientific websites from the inception of the research through May 20, 2018. We find great variety (20+) in measured outcomes among the 33 studies that pass our initial screening.
