Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is closely associated with many aspects of disturbed metabolic health. MASLD encompasses a wide spectrum of liver diseases, ranging from isolated steatosis to metabolic dysfunction-associated steatohepatitis (MASH), up to fibrosis, cirrhosis, and ultimately hepatocellular carcinoma. Limited noninvasive diagnostic tools are currently available to distinguish the various stages of MASLD and as such liver biopsy remains the gold standard for MASLD diagnostics.

Orthoflaviviruses cause a major threat to global public health, and no antiviral treatment is available yet. Zika virus (ZIKV) entry, together with many other viruses, is known to be enhanced by phosphatidylserine (PS) receptors such as T-cell immunoglobulin mucin domain protein 1 (TIM-1). In this study, we demonstrate for the first time, using cell-based electrical impedance (CEI) biosensing, that ZIKV entry is also enhanced by expression of CD300a, another PS receptor.

Metabolic-dysfunction-associated steatotic liver disease (MASLD) is a growing health problem for which no therapy exists to date. The modulation of the gut microbiome may have treatment potential for MASLD. Here, we investigated , a butyrate-producing anaerobic bacterium with beneficial effects in metabolic syndrome, in a diet-induced MASLD mouse model.

The transmembrane protein Sidestep (Side) functions as a substrate-bound attractant for motor axons in . Outgrowing motor axons recognize Side Beaten path Ia (Beat) and migrate along Side-expressing tissues. Here, we report a structure-function analysis of these guidance molecules using a variety of mutant lines and transgenic constructs.

Article Synopsis
  • Osteosarcoma (OS) is a rare and aggressive bone cancer with a complex genetic and cellular makeup, and survival rates have remained stagnant for 40 years despite advances in treatment.
  • The study investigated the role of lipopolysaccharide (LPS)-binding protein (LBP) in OS biopsies, finding higher LBP levels in local disease compared to metastatic cases, indicating the possible involvement of Gram-negative bacteria.
  • The findings suggest that the microbiome associated with OS could be crucial for developing new therapies aimed at improving treatment outcomes based on the tumor microenvironment.
