Mechanosensitive enteric neurons in the guinea pig gastric fundus and antrum.

Background: Coping with the ingested food, the gastric regions of fundus, corpus, and antrum display different motility patterns. Intrinsic components of such patterns involving mechanosensitive enteric neurons (MEN) have been described in the guinea pig gastric corpus but are poorly understood in the fundus and antrum.

Methods: To elucidate mechanosensitive properties of myenteric neurons in the gastric fundus and antrum, membrane potential imaging using Di-8-ANEPPS was applied.

Anti-Fibrotic Effect of SDF-1β Overexpression in Bleomycin-Injured Rat Lung.

Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease and is associated with high mortality due to a lack of effective treatment. Excessive deposition of the extracellular matrix by activated myofibroblasts in the alveolar space leads to scar formation that hinders gas exchange. Therefore, selectively removing activated myofibroblasts with the aim to repair and remodel fibrotic lungs is a promising approach.

Correction to: Azithromycin has enhanced effects on lung fibroblasts from idiopathic pulmonary fibrosis (IPF) patients compared to controls.

After publication of our article [1], we have been notified that an extra alpha symbol (α) was mistakenly added at the beginning of the title.

Azithromycin has enhanced effects on lung fibroblasts from idiopathic pulmonary fibrosis (IPF) patients compared to controls [corrected].

Background: Idiopathic pulmonary fibrosis (IPF) is a chronic fatal lung disease without a cure and new drug strategies are urgently needed. Differences in behavior between diseased and healthy cells are well known and drug response can be different between cells isolated from IPF patients and controls. The macrolide Azithromycin (AZT) has anti-inflammatory and immunomodulatory properties.

Volume-CLEM: a method for correlative light and electron microscopy in three dimensions.

Generation of three-dimensional (3D) data sets from serial sections of tissues imaged by light microscopy (LM) allows identification of rare structures by morphology or fluorescent labeling. Here, we demonstrate a workflow for correlative LM and electron microscopy (EM) from 3D LM to 3D EM, using the same sectioned material for both methods consecutively. The new approach is easy to reproduce in routine EM laboratories and applicable to a wide range of organs and research questions.
