Resiquimod induces a mixed Th1 and Th2 response via STAT1 and STAT3 signalling in chickens

Biochemistry and Biophysics Reports
Resiquimod (R-848), a synthetic TLR7 agonist, modulates immune responses, primarily inducing Th1-biased immunity in mammals. In contrast, our previous studies revealed that R-848 stimulates both Th1 and Th2 responses in chickens.

An Animal‐Free Patient‐Derived Tissue‐Mimetic Biochip Model of the Human Synovial Membrane for Human‐Relevant Osteoarthritis Research

Advanced Healthcare Materials, EarlyView.
Reihs et al. present the development of a humanized, animal‐free synovial membrane model for osteoarthritis. Methods include 3D biochip cultures of human‐primary OA synoviocytes with matrix and serum surrogates. Results show replication of synovial architecture and increased Yap1 expression.

Cold Atmospheric Plasma Selectively Disrupts Breast Cancer Growth in a Bioprinted 3D Tumor‐Stroma Co‐Culture Model

Advanced Healthcare Materials, EarlyView.
This research introduces a cold plasma‐based platform for treating breast cancer bone metastases. Using a novel bioprinted 3D tumor‐stroma model, it highlights the selective antitumor effects of plasma‐generated reactive species. The platform aims to advance non‐invasive therapeutic strategies, offering potential clinical applications in controlling ...

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Novel Drug‐Testing Platform for Vascular Injury‐induced Intimal Hyperplasia Using a Microphysiological System

Advanced Healthcare Materials, EarlyView.
This study develops a 3D vascular injury model using a microphysiological system that mimics key features of intimal hyperplasia. Antiproliferative drugs reduced VSMC proliferation but worsened endothelialdenudation. A combination of diphenyleneiodonium and quercetin effectively reduced proliferation and migration of VSMC and inflammation while ...
