Encapsulation of individual mammalian cells as a cell-based drug delivery carrier for lung cancer treatment.

Cell-based delivery holds great promise for advancing cell therapy, but it often faces challenges such as low cell survival rates and immunological rejection during cell injection and circulation. In this study, we develop an alternative approach aimed at engineering cell membranes to produce encapsulated individual mammalian (EIM) cells. The encapsulation shell was formed by catalyzing the reaction of HO with hyaluronic acid-dopamine (HA-DA) on the cell surface using horseradish peroxidase (HRP) enzymes.

Unraveling pathogenesis and potential biomarkers for autism spectrum disorder associated with HIF1A pathway based on machine learning and experiment validation.

Background: Autism spectrum disorder (ASD) is a neurodevelopmental disorder with a high social burden and limited treatments. Hypoxic condition of the brain is considered an important pathological mechanism of ASD. HIF1A is a key participant in brain hypoxia, but its contribution to the pathophysiological landscape of ASD remains unclear.

Highly stable 3D cellulose micro-rolls support TiO for efficient photocatalysis degradation experiment under weak light conditions.

Immobilization of nanometer-scale photocatalysts on a 3D polymeric substrate could play several complementary roles in photocatalysis, such as providing mechanical stability, facilitating easy recycling after usage, enhancing adsorption capability, and improving light harvesting properties through multiple reflections. To achieve stable and efficient photocatalysis under weak light conditions, 3D cellulose micro-rolls were introduced into the photocatalytic composites. Here, the formation of micro-rolls is attributed to the presence of titania nanoparticles, which generate uneven shrinkage stress in cellulose during the freeze-drying process, thereby inducing the cellulose to curl up.
