The loop of phenotype: Dynamic reciprocity links tenocyte morphology to tendon tissue homeostasis.

Acta Biomater 2022 May 15. Epub 2022 May 15.

Department of Biomedical Engineering, Eindhoven University of Technology, Eindhoven, The Netherlands; Institute for Complex Molecular Systems, Eindhoven University of Technology, Eindhoven, the Netherlands. Electronic address:

Cells and their surrounding extracellular matrix (ECM) are engaged in dynamic reciprocity to maintain tissue homeostasis: cells deposit ECM, which in turn presents the signals that define cell identity. This loop of phenotype is obvious for biochemical signals, such as collagens, which are produced by and presented to cells, but the role of biomechanical signals is also increasingly recognised. In addition, cell shape goes hand in hand with cell function and tissue homeostasis. Read More

Antagonism of histamine H receptor promotes angiogenesis following focal cerebral ischemia.

Acta Pharmacol Sin 2022 May 17. Epub 2022 May 17.

Department of Pharmacology and Department of Pharmacy of the Second Affiliated Hospital, Department of Anatomy, NHC and CAMS Key Laboratory of Medical Neurobiology, College of Pharmaceutical Sciences, Zhejiang University School of Medicine, Hangzhou, 310000, China.

Our previous study showed that H receptor antagonists reduced neuronal apoptosis and cerebral infarction in the acute stage after cerebral ischemia, but through an action independent of activation of histaminergic neurons. Because enhanced angiogenesis facilitates neurogenesis and neurological recovery after ischemic stroke, we herein investigated whether antagonism of HR promoted angiogenesis after brain ischemia. Photothrombotic stroke was induced in mice. Read More
