AI Article Synopsis

  • Cytokine release syndrome (CRS) is a severe complication of diseases like COVID-19, currently treated mainly with supportive therapy.
  • Researchers developed biomimetic nanoparticles by using macrophage membranes to neutralize cytokines associated with CRS, enhancing treatment potential.
  • Their findings indicated that nanoparticles derived from M0 macrophage membranes were the most effective in reducing inflammation and organ damage in mouse models.

Article Abstract

Cytokine release syndrome (CRS) is a severe complication of infectious diseases like Coronavirus disease 2019 (COVID-19) that cause serious damage to public health. Currently, supportive therapy is still the main therapeutic strategy exists for CRS treatment. Here, we show the potential of macrophage membrane-derived biomimetic nanoparticles for CRS treatment. By fusing macrophage membrane on the surface of the PLGA nano core, we constructed biomimetic nanoparticles that inherited the membrane receptors from the "parental" macrophages, enabling the neutralization of CRS-related cytokines. We compared three types of macrophage membranes to screen out more effective biomimetic nanoparticles for CRS treatment. Our results show that M0 macrophage membrane-derived biomimetic nanoparticles could neutralize pro-inflammatory cytokines involved in CRS to the greatest extent and reduce organ damage in a mouse model.

Department of Pharmacy, Personalized Drug Therapy Key Laboratory of Sichuan Province, Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital, School of Medicine, University of Electronic Science and Technology, Chengdu, 610054, China.

Despite being a groundbreaking approach to treating colorectal cancer (CRC), the efficacy of immunotherapy is significantly compromised by the immunosuppressive tumor microenvironment and dysbiotic intestinal microbiota. Here, leveraging the superior carrying capacity and innate immunity-stimulating property of living bacteria, a nanomedicine-engineered bacterium, LR-S-CD/CpG@LNP, with optical responsiveness, immune-stimulating activity, and the ability to regulate microbiota metabolome is developed. Immunoadjuvant (CpG) and carbon dot (CD) co-loaded plant lipid nanoparticles (CD/CpG@LNPs) are constructed and conjugated to the surface of Limosilactobacillus reuteri (LR) via reactive oxygen species (ROS)-responsive linkers.

Biomimetic gastric microtissue electrochemical biosensors for ovalbumin detection.

Biosens Bioelectron

December 2024

College of Food Science and Engineering, Collaborative Innovation Center for Modern Grain Circulation and Safety, Key Laboratory of Grains and Oils Quality Control and Processing, Nanjing University of Finance and Economics, Nanjing, Jiangsu, 210023, PR China. Electronic address:

An innovative integrated three-dimensional (3D) bioprinted gastric microtissue electrochemical biosensor was developed in this study for the detection of allergen ovalbumin (OVA). In this system, OVA triggers the release of histamine from gastric microtissue, which then undergoes a redox reaction on the electrode surface, leading to an increase in the peak current. Gelatin methacrylate hydrogel serves as a scaffold for the 3D culture of RBL-2H3 and PC-12 cells for partially restoring allergic reactions in the human body in vitro.
