Sorafenib Attenuates Liver Fibrosis by Triggering Hepatic Stellate Cell Ferroptosis via HIF-1α/SLC7A11 Pathway

Scientists investigate the functional role of hepatic stellate cell ferroptosis in the anti-fibrotic effect of sorafenib and found that sorafenib attenuated liver injury and extracellular matrix accumulation in CCl4-induced fibrotic livers, accompanied by reduction of SLC7A11 and GPX4 proteins.

Materials-Driven Fibronectin Assembly on Nanoscale Topography Enhances Mesenchymal Stem Cell Adhesion, Protecting Cells from Bacterial Virulence Factors and Preventing Biofilm Formation

The authors used a poly ethyl acrylate polymer coating on titanium nanowires to spontaneously organize fibronectin and to deliver bone morphogenetic protein 2 to enhance MSC adhesion and osteospecific signaling.

Neutrophil Gelatinase-Associated Lipocalin From Macrophages Plays a Critical Role in Renal Fibrosis Via the CCL5 (Chemokine Ligand 5)-Th2 Cells-IL4 (Interleukin 4) Pathway

The role of the CCL5 and IL4 in kidney fibrosis was studied by administration of the CCL5 receptor antagonist maraviroc or by injections of an anti-IL4 neutralizing antibody.

Cromolyn Platform Suppresses Fibrosis and Inflammation, Promotes Microglial Phagocytosis and Neurite Outgrowth

Scientists utilized cromolyn, a mast cell inhibitor with anti-inflammatory capabilities, and its fluorinated analogue F-cromolyn to study fibrosis-related protein regulation and secretion downstream of neuroinflammation and their ability to promote microglial phagocytosis and neurite outgrowth.

miRNA-200c-3p Targets Talin-1 to Regulate Integrin-Mediated Cell Adhesion

Overexpression of miR-200c-3p resulted in a remarkable decrease in the expression of TLN1, which was associated with the suppression of integrin-mediated cell adhesion to fibronectin.

Integrin α5β1 Nano-Presentation Regulates Collective Keratinocyte Migration Independent of Substrate Rigidity

The authors used a highly specific integrin α5β1 peptidomimetic combined with nanopatterned hydrogels to show that keratinocyte sheets regulated their migration ability at an optimal integrin α5β1 nanospacing.
