Chronic-inflammatory demyelinating polyneuropathy (CIDP) is an immune-mediated disease with no known biomarkers for diagnosing the disease or assessing its prognosis. We performed transcriptional profiling microarray analysis on skin punch biopsies from 20 CIDP patients and 17 healthy controls to identify disease-associated gene expression changes. We demonstrate changes in expression of genes involved in immune and chemokine regulation, growth and repair. We also found a combination of two upregulated genes that can be proposed as a novel biomarker of the disorder.

Idiopathic pulmonary fibrosis is a fatal disease characterized by the TGF-β-dependent activation of lung fibroblasts, leading to excessive deposition of collagen proteins and progressive replacement of healthy lung with scar tissue. We and others have shown that TGF-β-mediated activation of the Mechanistic Target of Rapamycin Complex 1 (mTORC1) and downstream upregulation of Activating Transcription Factor 4 (ATF4) promote metabolic reprogramming in lung fibroblasts characterized by upregulation of the de synthesis of glycine, the most abundant amino acid found in collagen protein. Whether mTOR and ATF4 regulate other metabolic pathways in lung fibroblasts has not been explored.

Purpose: Inflammatory processes have been involved in diabetic retinopathy (DR). Interleukin (IL)-17A, a pro-inflammatory cytokine, is associated with DR occurrence and development. However, mechanisms underlying the IL-17A impact on DR need further investigations.

Purpose: Because chickens have excellent light perception properties, this study focused on investigating whether monochromatic light can cause photodamage in chicken retinal ganglion cells (RGCs).
Methods: Post-hatching day chickens were exposed to four different light-emitting diode light environments for five weeks, respectively, monochromatic blue light (480 nm), green light (560 nm), red light (660 nm), or white light (6000 K). The mechanisms through which monochromatic light influences the structure of the chicken retina were analyzed by detecting the morphological structure of the retina, gene and protein expression levels, and the ultrastructure of the optic nerve.

Objective: Although sexual minority men experience substantial discrimination, in addition to increased risk for several serious mental and somatic health problems, the biological mechanisms underlying these effects are unclear. To address this issue, we examined how experiences of social safety (i.e.

Cell lineage analysis is primarily undertaken to understand cell fate specification and diversification along a cell lineage tree. Built with dual repressible markers, twin-spot mosaic analysis with repressible cell markers (MARCM) labels the two daughter cells made by a common precursor in distinct colors. The power of twin-spot MARCM to systematically subdivide complex lineages is exemplified in studies of Drosophila neural stem-cell lineages.
