La signalisation de CXCR4, un rhéostat de la réponse immunitaire à médiation humorale

, 2023
CXCR4 est un récepteur de chimiokine qui joue un rôle central dans la migration cellulaire mais également dans d’autres mécanismes essentiels, tels que le développement du système immunitaire. De concert avec son ligand naturel, la chimiokine CXCL12, cet

Expanded Hepatic Progenitor Cells Featured with Aggregation of α‐Synuclein Contribute to Pathologic Bile Duct Regeneration in Biliary Atresia

Advanced Science, EarlyView.
Expanded NCAM1+EpCAM+ hepatic progenitor cells in biliary atresia are characterized by aggregation of α‐synuclein. This pathological protein potentiates cellular susceptibility to GSH‐dependent redox dyshomeostasis, induces unstable biliary cell fate specification, and subsequently drives aberrant biliary regeneration.

Differential expression of SDF-1 receptor CXCR4 in molecularly defined forms of inherited thrombocytopenias

Platelets, 2017
The SDF-1-CXCR4 axis plays an essential role in the regulation of platelet production, by directing megakaryocyte (MK) migration toward the vascular niche, thus allowing terminal maturation and proplatelet formation, and also regulates platelet function ...

Agonists for the Chemokine Receptor CXCR4

ACS Medicinal Chemistry Letters, 2011
The development of agonists for the chemokine receptor CXCR4 could provide promising therapeutic candidates. On the basis of previously forwarded two site model of chemokine-receptor interactions, we hypothesized that linking the agonistic N-terminus of SDF-1 to the T140 backbone would yield new high-affinity agonists of CXCR4.

The role of the chemokine receptor CXCR4 in oral squamous cell carcinoma metastasis

, 2010
PhDOral Squamous Cell Carcinoma (OSCC) is the sixth most common cancer worldwide. The greatest cause of mortality and surgical morbidity is due to the common spread of tumour cells from the primary lesion to the lymph nodes of the neck. This pathway is

Modulation of the virus-receptor interaction by mutations in the V5 loop of feline immunodeficiency virus (FIV) following in vivo escape from neutralising antibody [PDF]

, 2010
<b>BACKGROUND:</b> In the acute phase of infection with feline immunodeficiency virus (FIV), the virus targets activated CD4+ T cells by utilising CD134 (OX40) as a primary attachment receptor and CXCR4 as a co-receptor.

Targeting a Myeloid–Regulatory B Cell Network Reverses Immune Paralysis in Periprosthetic Joint Infections

Advanced Science, EarlyView.
Periprosthetic joint infection establishes a sophisticated immunosuppressive network between CXCR4+ PMN‐MDSCs and Bregs, inducing profound CD8+ T cell paralysis. Alendronate effectively disrupts this CXCR4+ PMN‐MDSC–Breg axis by targeting STAT3, thereby restoring local immune surveillance.

Development and Validation of a Radiochemical Purity Determination Method for [68Ga]Ga-DOTA-CXCR4-D1

Journal of Isotopes
CXCR4 is a chemokine receptor widely overexpressed on the surface of various tumor cells. Given its pivotal role in tumor invasion，metastasis，and recurrence，it has emerged as a key target in molecular imaging.

SDF1 Gene Variation Is Associated with Circulating SDF1 alpha Level and Endothelial Progenitor Cell Number-The Bruneck Study

, 2008
BACKGROUND: Stromal cell-derived factor-1 (SDF1) and its receptor CXC chemokine receptor 4 (CXCR4) play a critical role in progenitor cell homing, mobilization and differentiation.

Condition‐Associated Pattern Extraction and Recovery From Multi‐Condition Single‐Cell RNA‐seq Data With CAPER

Advanced Science, EarlyView.
Decoupling biological signals from unwanted variation in multi‑condition single‑cell RNA sequencing data remains challenging. CAPER disentangles condition‑associated biological effects from sample heterogeneity through matrix factorization, producing interpretable latent factors and a batch‑corrected expression matrix.
