Single‐Cell Atlas of Subchondral Bone Marrow Lesions Reveals Proteostasis Dysfunction as a Druggable Mechanism for Early Osteoarthritis

Advanced Science, EarlyView.
This study reveals that abnormal mechanical stress downregulates the expression of HSP70 and impairs proteasome function in osteoarthritic bone cells, leading to misfolded collagen I accumulation and ER stress. When intracellular proteostasis capacity is exceeded, USP19 mediates the secretion of misfolded proteins into the extracellular space ...

Differential activity of pro-angiogenic CXC chemokines [PDF]

Microvascular Research, 2010
We showed previously in a mouse model of lung ischemia-induced angiogenesis, enhanced expression of the three ELR+ CXC chemokines (KC, LIX, and MIP-2) and that blockade of the ligand receptor CXCR(2) limited neovascularization. The present study was undertaken to determine the relative abundance and angiogenic potential of the three CXC chemokines and ...

Mapping CSC‐Mediated Ovarian Cancer Chemoresistance via CXCR4‐PET to Guide Precision Cisplatin Re‐Sensitization Therapy

Advanced Science, EarlyView.
CXCR4 functions as a potential cancer stem cell‐associated marker linked to chemoresistance in ovarian cancer, and an inhibitor of CXCR4, AMD3100, can enhance the cytotoxic response to cisplatin. Based on these findings, [68Ga]Ga‐Pentixafor positron emission tomography enables selective visualization of CXCR4‐high ovarian cancer, while AMD3100 combined

Chemokines and immunity

Einstein (São Paulo)
Chemokines are a large family of small cytokines and generally have low molecular weight ranging from 7 to 15kDa. Chemokines and their receptors are able to control the migration and residence of all immune cells.

Perivascular adipose tissue inflammation in vascular disease [PDF]

, 2017
Perivascular adipose tissue (PVAT) plays a critical role in the pathogenesis of cardiovascular disease. In vascular pathologies, perivascular adipose tissue increases in volume and becomes dysfunctional, with altered cellular composition and molecular ...

Neutrophil‐Mimetic Nanoscavengers Target the Inflammatory Microenvironment to Eliminate NETs/ROS and Immunomodulate cGAS‐STING Signaling in Septic AKI

Advanced Science, EarlyView.
Sepsis‐associated acute kidney injury is driven by oxidative stress, NETs overproduction, and dysregulated innate immunity. Here, we develop neutrophil‐mimetic nanoscavengers that integrate ROS‐scavenging Mn3O4 nanozymes with DNase‐1‐mediated NETs degradation to suppress cGAS‐STING signaling, reprogram macrophage polarization, and effectively alleviate

Macrophage transactivation for chemokine production identified as a negative regulator of granulomatous inflammation using agent-based modeling [PDF]

, 2018
Cellular activation in trans by interferons, cytokines and chemokines is a commonly recognized mechanism to amplify immune effector function and limit pathogen spread. However, an optimal host response also requires that collateral damage associated with

Engineering Tertiary Lymphoid Structures: Nanomedicine, Bioengineering, and Biomaterials for Precision Immunotherapy

Advanced NanoBiomed Research, EarlyView.
This review explains how biomaterials and nanoparticles can be used to induce or modulate tertiary lymphoid structures (TLSs), which are ectopic immune hubs that form in nonlymphoid tissues during chronic disease and cancer. By comparing different methods, the article highlights design principles for modeling TLSs or recapitulating specific TLS ...

Macrophages and chemokines as mediators of angiogenesis

Frontiers in Physiology, 2013
Accumulating evidence attests to the important roles of both macrophages and chemokines in angiogenesis. Tumor-associated macrophages or TAMS constitute the major fraction of tumor-infiltrating leukocytes and are recruited by a number of ...

Single cells from human primary colorectal tumors exhibit polyfunctional heterogeneity in secretions of ELR+ CXC chemokines [PDF]

, 2013
Cancer is an inflammatory disease of tissue that is largely influenced by the interactions between multiple cell types, secreted factors, and signal transduction pathways.
