AI Article Synopsis

  • Cytoprotection of living cells is crucial for applications in cell therapy, sensors, regenerative medicine, and food industry, focusing on maintaining cell viability under various conditions.
  • A two-step encapsulation process creates a uniform shell made of organic and inorganic materials, providing enhanced resistance to factors like lytic enzymes, desiccation, and UV-C light.
  • The study reveals that the encapsulated yeast not only benefits from the protective shell but also exhibits biochemical responses that enhance UV-C tolerance, making this approach useful for both cytoprotection and cellular behavior research.

Article Abstract

The cytoprotection of individual living cells under and daily-life conditions is a prerequisite for various cell-based applications including cell therapy, cell-based sensors, regenerative medicine, and even the food industry. In this work, we use a cytocompatible two-step process to encapsulate in a highly uniform nanometric (<100 nm) shell composed of organic poly(norepinephrine) and inorganic silica layers. The resulting cell-in-shell structure acquires multiple resistance against lytic enzyme, desiccation, and UV-C irradiation. In addition to the UV-C filtering effect of the double-layered shell, the biochemical responses of the encapsulated yeast are suggested to contribute to the observed UV-C tolerance. This work offers a chemical tool for cytoprotecting individual living cells under multiple stresses and also for studying biochemical behavior at the cellular level.

Background: Acute pancreatitis (AP) presents a significant clinical challenge with limited therapeutic options. The complex etiology and pathophysiology of AP emphasize the need for innovative treatments. This study explores mRNA-based therapies delivering fibroblast growth factor 21 (FGF21) and apolipoprotein A1 (APOA1), alone and in combination, for treating experimental AP.

Parkinson's disease (PD) is a widespread age-related neurodegenerative disorder characterized by the presence of an aggregated protein, α-synuclein (α-syn), which is encoded by the gene and localized to presynaptic terminals in a normal human brain. The α-syn aggregation is induced by the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mitochondrial neurotoxin and is therefore used to mimic PD-like pathology in various in vitro and in vivo models. However, in vitro PD-like pathology using α-syn and MPTP in human microglial cells has not yet been reported.

Background: Thrombomodulin, a thrombin receptor with anticoagulant, anti-inflammatory, and cytoprotective properties, has been suggested to play a pivotal role in ischemic stroke. However, the association of plasma thrombomodulin with post-stroke cognitive impairment (PSCI) remains unclear. We aimed to prospectively investigate the associations of plasma thrombomodulin with PSCI among ischemic stroke patients in a multicenter cohort study.

Oenobiol Sun Expert, a food formulation designed to enhance skin health prior to sun exposure, has been optimized by incorporating the OenoGrape Advanced Complex, which includes grape pomace extract, increased selenium content and 10% lycopene-rich tomato extract, with these constituents exhibiting high antioxidant potential. To evaluate the effects of these individual ingredients and the overall formulation at the cellular level, the AOP1 cell antioxidant efficacy assay was employed to measure the intracellular free radical scavenging activity, while the Cell Antioxidant Assay (CAA or DCFH-DA) assay was used to assess peroxidation scavenging at the plasma membrane level. The indirect antioxidant activity was examined using stably transfected cell lines containing a luciferase reporter gene controlled by the Antioxidant Response Element (ARE), which activates the endogenous antioxidant system via the Nrf2/Keap1-ARE pathway.
