Targeting Transdifferentiated Hepatic Stellate Cells and Monitoring the Hepatic Fibrogenic Process by Means of IGF2R-Specific Peptides Designed In Silico

The structural information of the insulin-like growth factor 2 receptor (IGF2R), an overexpressed protein on activated hepatic stellate cells, were used for an in silico screening of novel IGF2R-specific peptide ligands.

Vulnerability to Shear Stress Caused by Altered Peri-Endothelial Matrix Is a Key Feature of Moyamoya Disease

Hyaluronan synthase 2 was strongly expressed in endothelial progenitor cells in the thickened intima. Moyamoya disease lesions showed minimal staining for chondroitin sulfate and hyaluronan in the endothelium, in contrast to control endothelium showing positive staining for both.

DNA Nanostructures as Templates for Biomineralization

Nature uses ECM scaffolds to organize biominerals into hierarchical structures over various length scales. This has inspired the design of biomimetic mineralization scaffolds, with DNA nanostructures being among the most promising. DNA nanotechnology makes use of molecular recognition to controllably give 1D, 2D and 3D nanostructures.
