The pupal forewing dorsal epidermis was a pseudostratified monolayer of vertically elongated epidermal cells.

Inhibition of peptidyl arginine deiminase-4 ameliorated pulmonary fibrosis via modulating M1/M2 polarisation of macrophages.

Pulmonary fibrosis (PF) arises from dysregulated wound healing, leading to excessive extracellular matrix (ECM) deposition and impaired lung function. Macrophages exhibit high plasticity, polarizing to pro-inflammatory M1 during early inflammation and anti-inflammatory, fibrosis-inducing M2 during later stages of PF. Additionally, neutrophils and neutrophil extracellular traps (NETs) release mediated by peptidyl arginine deiminase (PAD-4), also play a key role in PF progression.

These proteins often contain intrinsically disordered activation domains (ADs) that regulate their transcriptional activity. Like other disordered protein regions, ADs do not have a fixed three-dimensional structure and instead exist in an ensemble of conformations.

The Trail of axonal protein Synthesis: Origins and current functional Landscapes.

Local protein synthesis (LPS) in axons is now recognized as a physiological process, participating both in the maintenance of axonal function and diverse plastic phenomena. In the last decades of the 20th century, the existence and function of axonal LPS were topics of significant debate. Very early, axonal LPS was thought not to occur at all and was later accepted to play roles only during development or in response to specific conditions.

Moderate levels of folic acid benefit outcomes for cilia based neural tube defects.

Folic acid (FA) supplementation is a potent tool to reduce devastating birth defects known as neural tube defects (NTDs). Though effective, questions remain how FA achieves its protective effect and which gene mutations are sensitive to folic acid levels. We explore the relationship between FA dosage and NTD rates using NTD mouse models.
