Abstract Amidst the rising prevalence of respiratory diseases, importance effective lung treatment modalities is more critical than ever. However, current drug delivery systems face significant limitations that impede their efficacy and therapeutic outcome. Biohybrid microrobots have shown considerable promise for active in vivo delivery, especially pulmonary applications via intratracheal routes. invasive nature administration poses barriers to its clinical translation. Herein, we report on...

Toll-like receptors (TLRs) trigger intestinal inflammation when the epithelial barrier is breached by physical trauma or pathogenic microbes. Although it has been shown that TLR-mediated signals are ultimately protective in models of acute [such as dextran sulfate sodium (DSS)-induced colitis], less clear which cells mediate protection. Here we demonstrate TLR signaling nonhematopoietic compartment confers protection DSS-induced colitis. Epithelial MyD88/Trif-deficient mice express...

The hypothalamus is the central regulator of systemic energy homeostasis, and its dysfunction can result in extreme body weight alterations. Insights into complex cellular physiology this region are critical to understanding obesity pathogenesis; however, human hypothalamic cells largely inaccessible for direct study. Here, we developed a protocol efficient generation neurons from embryonic stem (ESCs) induced pluripotent (iPSCs) obtained patients with monogenetic forms obesity. Combined...

Over 40 missense mutations in the human SCN1A sodium channel gene are linked to an epilepsy syndrome termed genetic with febrile seizures plus (GEFS+). Inheritance of GEFS+ is dominant, but underlying cellular mechanisms remain poorly understood. Here we report that knock-in a mutation (K1270T) into Drosophila gene, para , causes semidominant temperature-induced seizure phenotype. Electrophysiological studies GABAergic interneurons brains adult flies reveal novel mechanism heat-induced...

Deficiencies of subunits the transcriptional regulatory complex Mediator generally result in embryonic lethality, precluding study its physiological function. Here we describe a missense mutation Med30 causing progressive cardiomyopathy homozygous mice that, although viable during lactation, show precipitous lethality 2–3 wk after weaning. Expression profiling reveals pleiotropic changes transcription cardiac genes required for oxidative phosphorylation and mitochondrial integrity. Weaning...

Abstract Nanodiscs are a compelling nanomedicine platform due to their ultrasmall size and distinct disc shape. Current nanodisc formulations made primarily with synthetic lipid bilayers proteins. Here, we report cellular human red blood cell (RBC) membrane (denoted “RBC‐ND”) show its effective neutralization against bacterial toxins. In vitro, RBC‐ND neutralizes the hemolytic activity cytotoxicity caused by purified α‐toxin or complex whole secreted proteins (wSP) from methicillin‐resistant...

Glucaric acid (GA) is a value-added chemical and can be used to manufacture food additives, anticancer drugs, polymers. The non-genetic cell-to-cell variations in GA biosynthesis are naturally inherent, indicating the presence of both high- low-performance cells culture. Low-performance lead nutrient waste inefficient production. Furthermore,

Robust strategies for developing patient-specific, human, induced pluripotent stem cell (iPSC)-based therapies of the brain require an ability to derive large numbers highly defined neural cells. Recent progress in iPSC culture techniques includes partial-to-complete elimination feeder layers, use media, and single-cell passaging. However, these still embryoid body formation or coculture differentiation into cells (NSCs). In addition, none published methodologies has employed all advances a...

Abstract Aptamers are single‐stranded oligonucleotides that fold into defined architectures for specific target binding. In this study, aptamers selected specifically bind to small‐molecule neurotoxins and encapsulate them cell membrane‐coated nanoparticles (referred as ‘cellular nanoparticles’ or ‘CNPs’) effective neutralization of neurotoxins. Specifically, six different saxitoxin (STX) tetrodotoxin (TTX) metal–organic framework cores, which then coated with neuronal membrane. The...
