Marek's disease virus (MDV), a highly contagious and oncogenic avian alphaherpesvirus, establishes a latent infection primarily in CD4 T cells. Latent infections are necessary for both persistent lifelong MDV infection and viral tumorigenesis. MicroRNAs (miRNAs) play critical roles as post-transcriptional regulators of viral infections.

Purpose: Treatment of severe burn wound injury remains a significant clinical challenge as serious infections/complex repair process and irregulating inflammation response. Human umbilical cord mesenchymal stem cells (hUC-MSCs) have a multidirectional differentiation potential and could repair multiple injuries under appropriate conditions. Poly(L-lysine)-graft-4-hydroxyphenylacetic acid (PLL-g-HPA) hydrogel is an enzyme-promoted biodegradable in hydrogel with good water absorption, biocompatibility and anti-bacterial properties.

Crohn's disease (CD) is a chronic inflammatory autoimmune disease of unknown etiology. To identify new targets related to the initiation of CD, we screened a pair of twins with CD, which is a rare phenomenon in the Chinese population, for genetic susceptibility factors. Whole-exome sequencing (WES) of these patients revealed a mutation in their SERPINB4 gene.

Alzheimer's disease (AD) is a progressive neurodegenerative condition characterized by the deposition of amyloid-β (Aβ) peptides, which aggregate into toxic structures such as oligomers, fibrils, and plaques. The presence of these Aβ aggregates in the brain plays a crucial role in the pathophysiology, leading to synaptic dysfunction and cognitive impairment. Understanding how physiological factors affect Aβ aggregation is essential, and therefore, exploring their influence in vitro will likely provide insights into their role in AD pathology.

The amino acid l-arginine (Arg) plays important roles in multiple metabolic and physiological processes, and changes in its concentration have been implicated in pathological processes. While it is important to measure Arg levels in biological systems directly and in real-time, existing Arg sensors respond to l-ornithine or l-lysine. Here we report ArgS1, a new Arg sensor.
