Anti-inflammatory and antioxidative effects of heat-killed Lactococcus lactis KC24 via modulation of NF-κB and Nrf2 pathways in HO-stressed A549 cells.

Oxidative stress can contribute to various chronic diseases due to the excessive accumulation of reactive oxygen species (ROS). The lungs are particularly vulnerable to oxidative stress caused by environmental and intrinsic factors, and likely to cause asthma, chronic obstructive pulmonary disease, and lung cancer. Lactococcus lactis KC24, isolated from kimchi, has been reported to exert neuroprotective effects as a heat-killed paraprobiotic.

Lysosome-Targeting Chimera Using Mannose-6-Phosphate Glycans Derived from Glyco-Engineered Yeast.

Lysosome-targeting chimeras (LYTACs) harness the cell's lysosomal degradation machinery to break down extracellular and membrane proteins. Previous methods used a synthetic glycopeptide containing multiple serine-O-mannose-6-phosphate (poly-M6Pn), which presented challenges such as synthetic complexity and potential immunogenicity associated with poly-M6Pn. This study introduced a LYTAC formulation, LYTAC, which uses glyco-engineered yeast-derived mannose-6-phosphate glycans (gyM6pGs) for lysosomal transport, overcoming synthetic complexities and immunogenic risks.

BAP1 controls mesenchymal stem cell migration by inhibiting the ERK signaling pathway.

Due to their stem-like characteristics and immunosuppressive properties, Mesenchymal stem cells (MSCs) offer remarkable potential in regenerative medicine. Much effort has been devoted to enhancing the efficacy of MSC therapy by enhancing MSC migration. In this study, we identified deubiquitinase BRCA1- associated protein 1 (BAP1) as an inhibitor of MSC migration.
