A Skull Bone Marrow‐to‐Brain Axis Links Osteoblastic Activity to Myeloid Cell Trafficking, Cerebral Blood Flow, and Cognition in Alzheimer's Progression

Advanced Science, EarlyView.
This study reveals that Alzheimer's disease–linked APP expression in bone‐forming cells drives skull bone marrow remodeling and alters its vascular connections to the brain. These changes disrupt immune cell trafficking, cerebral blood flow, and cognition. Targeting bone marrow macrophages restores brain function, highlighting a previously unrecognized

Alterations of CCR2 and CX3CR1 on Three Monocyte Subsets During HIV-1/Treponema pallidum Coinfection

Frontiers in Medicine, 2020
HIV-1/Treponema pallidum (T. pallidum) coinfection has become a global challenge, and three monocyte subsets express varying levels of the chemokine receptors CCR2 and CX3CR1.

PGK1 Suppresses CD8+ T Cell‐Mediated Antitumor Immunity Through CCL2/CCR2/Tumor‐Associated Macrophages Axis in Hepatocellular Carcinoma

Advanced Science, EarlyView.
PGK1 in tumor cells upregulates CCL2 expression through activation of the AKT/GSK‐3β/β‐catenin signaling axis, thereby promoting the recruitment and M2 polarization of TAMs and ultimately impairing the infiltration and activation of CD8+ T cells within the HCC tumor microenvironment. ABSTRACT Patients with advanced hepatocellular carcinoma (HCC) have a

Important role of CCR2 in a murine model of coronary vasculitis

BMC Immunology, 2012
Background Chemokines and their receptors play a role in the innate immune response as well as in the disruption of the balance between pro-inflammatory Th17 cells and regulatory T cells (Treg), underlying the pathogenesis of coronary vasculitis in ...

A Dual‐Phase Exosomal Nanotherapy Enhances Continual Efferocytosis by Coordinating Checkpoint Inhibition and Metabolic Reprogramming in Atherosclerosis

Advanced Science, EarlyView.
Here we developed Am@SExo, a dual‐functional engineered exosome that coordinates CD47–SIRPα checkpoint blockade with Arg1 mRNA–mediated metabolic reprogramming. Surface SIRPα promotes recognition of apoptotic cells and plaque targeting, while Arg1 expression enhances arginine–ornithine metabolism, Rac1 activation, and actin remodeling in macrophages ...

N-Formylated Peptide Induces Increased Expression of Both Formyl Peptide Receptor 2 (Fpr2) and Toll-Like Receptor 9 (TLR9) in Schwannoma Cells—An In Vitro Model for Early Inflammatory Profiling of Schwann Cells

Cells, 2020
Following nerve injury, disintegrated axonal mitochondria distal to the injury site release mitochondrial formylated peptides and DNA that can induce activation and inflammatory profiling of Schwann cells via formyl peptide receptor 2 (Fpr2) and toll ...

From Defense Executor to Engineering Target: Harnessing Lignin for Crop Resistance

Advanced Science, EarlyView.
Lignin serves as both a physical and chemical executor of broad‐spectrum plant immunity. This review systematically summarizes classical and recent advances in lignin‐mediated immunity, outlines the multifaceted regulatory modules controlling lignification under biotic stress, discusses key physiological and biochemical mechanisms behind lignin‐based ...

Human Urine Stem Cells Alleviate Pulmonary Fibrosis via Inhibiting Macrophage‐Myofibroblast Transition

Advanced Science, EarlyView.
Therapeutic role and mechanism of human urine stem cells (hUSCs) in pulmonary fibrosis. hUSCs alleviated pulmonary fibrosis by selectively inhibiting macrophage‐myofibroblast transition (MMT) in two ways: on one hand, hUSCs inhibited mitochondrial reactive oxygen species (mtROS) production and apoptosis/senescence of epithelial cells in pulmonary ...

Análise de receptores de quimiocinas na superfície de leucócitos circulantes de indivíduos infectados pelo Mycobacterium leprae: resultados preliminares Analysis of chemokine receptors on the surface of circulating leukocytes of individuals infected with Mycobacterium leprae: preliminary results

Revista da Sociedade Brasileira de Medicina Tropical, 2008
Neste estudo, a expressão de receptores de quimiocinas na superfície dos leucócitos circulantes foi feita pela citometria de fluxo. Houve aumento da porcentagem de linfócitos CCR2+CD4+ no sangue periférico dos pacientes com hanseníase.

Hematoma Interleukin‐1 Receptor Antagonist Concentrations Predict Long‐Term Outcome in Acute Human Intracerebral Hemorrhage

Annals of Neurology, EarlyView.
Objectives The interleukin (IL)‐1, IL‐6, and C‐reactive protein (CRP) pathway is central to the immune response after intracerebral hemorrhage (ICH). We tested for associations between hematoma and plasma cytokine concentrations and patient outcomes in Minimally Invasive Surgery Plus Rt‐PA for ICH Evacuation Phase III (MISTIE III) participants ...
