AI Article Synopsis

  • Macrophages are important cells in our body's immune system that help fight diseases and infections.
  • Researchers often use a special method to remove these cells from mice to study how they work.
  • This study explains a new way to take out macrophages and then replace them with modified ones to help understand what happens during infections like sepsis.

Article Abstract

Macrophages are key innate immune cells involved in a broad spectrum of physiological and pathological processes. Macrophage depletion with clodronate-liposomes is commonly used to investigate functions of macrophages in mice. Here, we describe a protocol that combines the depletion of resident macrophages with the reconstitution of the mice with differentiated, lentivirus-transduced bone marrow-derived macrophages (BMDMs) in the context of an experimental sepsis model. This experimental strategy is easily adapted to other experimental designs. For complete details on the use and execution of this protocol, please refer to Du et al. (2020).

The development of efficient therapeutic strategies to promote ferroptotic cell death offers significant potential for hepatocellular carcinoma (HCC) treatment. Herein, this study presents an HCC-targeted nanoplatform that integrates bimetallic FeMoO nanoparticles with CO-releasing molecules, and further camouflaged with SP94 peptide-modified macrophage membrane for enhanced ferroptosis-driven multi-modal therapy of HCC. Leveraging the multi-enzyme activities of the multivalent metallic elements, the nanoplatform not only decomposes HO to generate oxygen and alleviate tumor hypoxia but also depletes glutathione to inactivate glutathione peroxides 4, which amplify sonodynamic therapy and ferroptotic tumor death under ultrasound (US) irradiation.

Background: Microglia play a critical role in the pathogenesis and development of Alzheimer's disease (AD). Selective small-molecule colony-stimulating factor 1 receptors (CSF1R) inhibitor, designed to deplete microglia, could be used to meliorate AD. This study aimed to investigate the effects and mechanisms of chimeric antigen receptor T (CAR-T) cells targeting CSF1R in 6-month-old APP/PS1 male mice.

Developing low-toxicity, high-efficacy, and fast-acting strategies to manage acute liver injury (ALI) is critical due to its rapid progression and potential for severe outcomes. Curcumin (CUR) has shown promise in ALI therapy due to its ability to modulate the inflammatory microenvironment by scavenging reactive oxygen species (ROS). Nevertheless, CUR is highly hydrophobic limiting its bioavailability and effective in vivo transport, which hinders its further application.

CD4+ T cells contribute to antitumor immunity and are implicated in the efficacy of cancer immunotherapies. In particular, CD4+ T helper 2 (Th2) cells were recently found to block spontaneous breast carcinogenesis. However, the antitumor potential of Th2 cells in targeting established breast cancer remains uncertain.

Introduction: Postoperative ileus (POI) is an iatrogenic disorder marked by temporary impaired gastrointestinal (GI) motility post-abdominal surgery. Surgical handling of the intestine activates resident macrophages (Mfs), leading to inflammatory cytokine release and leukocyte recruitment into the muscularis, which compromises intestinal contractility. The mechanisms behind this activation are unclear.
