Vascular smooth muscle cell apoptosis in atherosclerosis [PDF]

open access: yesInternational Journal of Experimental Pathology, 1999
Cell death has long been recognized within the vessel wall, in particular, in disease states such as atherosclerosis. The use of the term ‘necrotic core’ for the central lipid core of advanced lesions emphasizes this. Indeed there is obvious cell fragmentation and cell debris in areas of plaques, particularly the lipid core (Mitchinson et al.

Advancements in Carbon‐Based Piezoelectric Materials: Mechanism, Classification, and Applications in Energy Science

open access: yesAdvanced Materials, EarlyView.
Carbon‐based piezoelectric materials are systematically categorized based on their structural and functional properties. The mechanisms of stress‐induced charge transfer are elucidated, and their applications are explored across three key domains: piezoelectric catalysis for energy conversion and environmental remediation, piezoelectric biomedical ...

Plaque‐Targeted Delivery of Fluoride‐Free MXene Nanozyme for Alleviating Atherosclerosis via Sonocatalytic Therapy

open access: yesAdvanced Materials, EarlyView.
This work has developed a dual enzyme‐mimicking and ultrasound‐responsive Nb2C‐Pt@HA‐PEG nanozyme. ROS‐eliminating and anti­inflammatory capability of Nb2C‐Pt@HA‐PEG under US irradiation are demonstrated on macrophages and endothelial cells in vitro. Nb2C‐Pt@HA‐PEG‐mediated sonocatalytic therapy exerts an outstanding anti‐atherosclerosis efficacy by ...

Cell Autonomous and Non-cell Autonomous Regulation of SMC Progenitors in Pulmonary Hypertension

open access: yesCell Reports, 2018
Summary: Pulmonary hypertension is a devastating disease characterized by excessive vascular muscularization. We previously demonstrated primed platelet-derived growth factor receptor β+ (PDGFR-β+)/smooth muscle cell (SMC) marker+ progenitors at the ...

De Novo Design of Integrin α5β1 Modulating Proteins to Enhance Biomaterial Properties

open access: yesAdvanced Materials, EarlyView.
NeoNectins are de novo‐designed miniproteins that selectively bind and stabilize the extended open form of integrin α5β1. When grafted onto biomaterials including hydrogel and titanium, they promote cell attachment and spreading in vitro and promoting tissue integration and bone growth in animal models, demonstrating broad potential for regenerative ...
