Morganella morganii is an opportunistic pathogen affecting immunocompromised and hospitalized intensive care patients. It colonizes diverse environments and exhibits multidrug resistance. Its genome encodes factors that impart pathogenicity and resistance to multiple antibiotics. This study provided insights into the resistome, mobilome, and toxin-antitoxin systems of M. morganii strains from human clinical samples, food, animals, and wastewater. The pangenome predicted 2,852 core genes shared...

Lipid nanoparticles (LNPs) are clinically established carriers for nucleic acid therapeutics and mRNA-based vaccines. Current LNP formulations often use poly(ethylene glycol) (PEG)-based surface modifications to enhance pharmacokinetics, colloidal stability, and shelf life. However, PEG moieties can elicit anti-PEG immune responses, reactogenicity, and hypersensitivity reactions. Here, we investigated heparosan (HEP), a naturally occurring, biodegradable polysaccharide, for mRNA-LNP surface...

CONCLUSIONS/SIGNIFICANCE: Our rigorous systematic review is the first to consider risk factors of human and porcine T. solium disease simultaneously, allowing a synthesis of information from both hosts in order to elucidate causal mechanisms for risk factors of cysticercosis. Our work also highlights areas of T. solium epidemiology which are understudied, such as the causal mechanisms of taeniasis.

Reducing activity of the mechanistic/mammalian target of rapamycin (mTOR) with rapamycin extends lifespan and healthspan in many species. The mechanisms by which mTOR regulates lifespan and healthspan, however, are still unknown. Understanding how mTOR signaling in different cell types regulates lifespan and aspects of healthspan is urgently needed if we are to harness the potential individual and societal benefits of healthspan extension by mTOR attenuation. mTOR kinase can form two complexes,...

Long COVID affects a substantial proportion of individuals recovering from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, yet its underlying pathophysiology remains poorly understood. Although autoimmunity is increasingly implicated in disease pathogenesis, routine diagnostics frequently fail to detect relevant immune dysregulation. To address this gap, we analyzed sera from Long COVID patients (n = 114) and pre-pandemic controls (n = 36) using tissue-based Western...
