CD4+ Tregs Drive Post‐Ischemic Sprouting Angiogenesis via Endothelial YY1/MAML1 Reactivation

Advanced Science, EarlyView.
ABSTRACT Microvascular complications of diabetes are chronic diseases of small vessels. We previously found that CD4+ regulatory T‐cells (Tregs) are markedly reduced in type 2 diabetes (T2D) after ischemic injury in both mice and humans, and that Treg deficiency in immunodeficient mice impairs vascular regeneration.

Decoding IGLL5 Mutation‐Mediated BCR Signaling: A Novel Mechanism of CD8+ T Cell Exhaustion and Ocular MALT Lymphoma Progression

Advanced Science, EarlyView.
OAML harbors recurrent IGLL5 mutations that reinforce CD79A/CD79B‐associated BCR signaling. Mechanistic analysis of the S47G and A54G variants reveals induction of CXCL10/CXCL11, enhanced CD8+ T‐cell recruitment, and exhaustion‐associated dysfunction, supporting an immune‐tolerant niche.

Blockade of CC chemokine receptor 2 suppresses pancreatic cancer progression through the interaction with macrophages in the tumor microenvironment

Scientific Reports
Pancreatic ductal adenocarcinoma (PDAC) is the most intractable cancer, demonstrating abundant stroma in the tumor microenvironment (TME). Previously, we reported that CXC chemokines contributed to the progression of PDAC through tumor-stromal ...

Tumor‐Derived Alpha‐1 Antitrypsin Promotes Liver Metastasis of Colorectal Cancer Through the Neutrophil Extracellular Traps–CCDC25 Pathway

Advanced Science, EarlyView.
ABSTRACT Liver metastasis is a leading cause of mortality in colorectal cancer (CRC), where the inflammatory tumor microenvironment, specifically neutrophil infiltration, significantly promotes metastatic colonization. This study reveals a pro‐metastatic role for alpha‐1 antitrypsin (A1AT) in CRC liver metastasis via a dual mechanism involving ...

Expression of CC-chemokines, CCR5 and chemokine mRNA expression in PBMC cultures after drug treatment.

, 2013
Panel A: Production of CC-chemokines by PBMC and the effects of adefovir, tenofovir, and PMEO-DAPym on the expression of the CCR5 receptor. Freshly isolated PBMCs from four healthy donors were incubated for 24 h with medium only (NC) or with adefovir ...

Systemic and Local CC Chemokines Production in a Murine Model of Listeria monocytogenes Infection

Mediators of Inflammation, 2006
Repeated intragastric inoculation of Listeria monocytogenes into BALB/c mice resulted in prolonged bacteraemia and severe hepatic infection. Bacteria could also be isolated from the brain tissue of all experimental mice.

Re: Chemokines in Cancer

Journal of Urological Surgery, 2016
Chemokines are chemotactic cytokines that regulate the trafficking and positioning of cells by activating the seven-transmembrane spanning G protein-coupled chemokine receptors (GPCR) or non G protein-coupled seven-transmembrane spanning receptors called

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

Human eosinophil adhesion and degranulation stimulated with eotaxin and RANTES in vitro: Lack of interaction with nitric oxide

BMC Pulmonary Medicine, 2008
Background Airway eosinophilia is considered a central event in the pathogenesis of asthma. The toxic components of eosinophils are thought to be important in inducing bronchial mucosal injury and dysfunction.

A Keratinocyte‐Mast Cell NF‐κB2/CXCL2/IL‐6 Amplification Loop Enhances Cutaneous Antifungal Defense Against C. albicans

Advanced Science, EarlyView.
ABSTRACT Mast cells (MCs), key innate immune sentinels at the host–environment interface, serve as primary responders to invading pathogens. However, their specific contribution to host defense against cutaneous Candida albicans (C. albicans) infection and their synergy with other immune and non‐immune cells remain poorly understood. Here, we show that
