Advanced Functional Materials, EarlyView.The temporary transition of macrophages from a pro‐inflammatory phenotype of macrophages (M1) to an anti‐inflammatory phenotype of macrophages (M2) is crucial for tissue repair and regeneration processes. Bacterial outer membrane vesicles (OMVs) are utilized as a “trojan horse” for specific M1 macrophage‐targeting and anti‐inflammatory drug delivery ...

Advanced Functional Materials, EarlyView.Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Phosphatase to kinase switch of a critical enzyme contributes to timing of cell differentiation
mBioCell differentiation is an essential biological process that is subject to strict temporal regulation. Caulobacter crescentus undergoes obligate differentiation from a swarmer cell to a stationary, replication-competent stalked cell with each cell cycle.

Bistable MAP Kinase Activity: A Plausible Mechanism Contributing to Maintenance of Late Long-Term Potentiation [PDF]
Am J Physiol Cell Physiol. 2008; v294, C503-C515, 2008 Bistability of MAP kinase (MAPK) activity has been suggested to contribute to several cellular processes, including differentiation and long-term synaptic potentiation. A recent model (48) predicts bistability due to interactions of the kinases and phosphatases in the MAPK pathway, without feedback from MAPK to earlier reactions.

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration
Advanced Functional Materials, EarlyView.A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Quorum sensing contributes to activated B cell homeostasis and to prevent autoimmunity [PDF]
arXiv, 2012 Maintenance of plasma IgM levels is critical for immune system function and homeostasis in humans and mice. However, the mechanisms that control homeostasis of the activated IgM-secreting B cells are unknown. After adoptive transfer into immune-deficient hosts, B-lymphocytes expand poorly but fully reconstitute the pool of natural IgM-secreting cells ...

Supervariate Gel Transforms into Various Biominerals in Salt Solutions
Advanced Functional Materials, EarlyView.It is revealed that common calcium‐based biominerals can form from a stable, non‐toxic ‘supervariate’ gel. This tunable gel selectively yields calcite or hydroxyapatite in carbonate/phosphate solutions, while CaCl₂ facilitates the formation of dihydrate calcium pyrophosphate, which converts to hydroxyapatite upon drying. These findings provide insights

Cerium Oxide Nanoparticles Role as Antioxidant
Medical Journal of BabylonCerium oxide nanoparticles (NPs), also known as ceria NPs, are particles of cerium oxide with sizes in the nanometer range. Cerium oxide (CeO2) is a compound composed of cerium and oxygen, and when it is reduced to NPs, it exhibits unique properties and ...
