OBJECTIVE To evaluate C-C chemokine receptor type 2 (CCR2) on monocyte subsets as a prognostic peripheral blood biomarker of HIV-associated neurocognitive disorders (HAND). METHODS We characterized monocyte populations in HIV-infected individuals with and without HAND from 2 cohorts and assessed their transmigration across an in vitro model of the human blood-brain barrier (BBB). We examined ...

Organ-specific patterns of myeloid cells may contribute tissue-specific growth and/or regenerative potentials. The perinatal stage of pancreas development marks a time characterized by maximal proliferation of pancreatic islets, ensuring the maintenance of glucose homeostasis throughout life. Ontogenically distinct CX3CR1+ and CCR2+ macrophage populations have been reported in the adult pancrea...

Limbal stem cell (LSC) deficiency is a frequent and severe complication after chemical injury to the eye. Previous studies have assumed this mediated directly by caustic agent. Here we show that LSC damage occurs through immune mediators, even without direct LSCs. In particular, pH elevation in anterior chamber (AC) causes acute uveal stress, release of inflammatory cytokines at basal limbal ti...

background: despite advances in the medical care of renal transplant recipients which have led to an improvement in allograft survival, renal allograft rejection is still a major ob-stacle to successful organ transplantation. understanding the mechanisms contributing to allograft rejection will be of great importance for the development of efficient antirejection strategies. objective: the aim ...

The origins of dendritic cells (DCs) are poorly understood. In inflammation, DCs can arise from blood monocytes (M(O)s), but their steady-state origin may differ, as shown for Langerhans cells. Two main subsets of M(O)s, defined by expression of different chemokine receptors, CCR2 and CX(3)CR1, have been described in mice and humans. Recent studies have identified the inflammatory function of C...

PURPOSE Monocytes actively participate in inflammatory mechanisms that contribute to the development of adipose tissue dysfunction and atherogenesis. The aim of this study was to evaluate the association of monocyte CCR2 chemokine receptor expression and intracellular oxidative burst with the metabolic and inflammatory factors related to body weight. METHODS The study was performed in 67 post...

BACKGROUND Fibrocytes are a population of circulating bone-marrow-derived cells that express surface markers for leukocytes and mesenchymal cells, and are capable of differentiating into myofibroblasts. They have been observed at sites of active fibrosis and increased circulating numbers correlate with mortality in idiopathic pulmonary fibrosis (IPF). Inhibition of chemokine (C-C motif) recepto...

Graft-versus-host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (HSCT). Migration of donor-derived T cells into GVHD target organs plays a critical role in the development of GVHD and chemokines and their receptors are important molecules involved in this process. Here, we demonstrate in murine bone marrow transplantation models that the expression...

UNLABELLED Perineural invasion is a form of cancer progression where cancer cells invade along nerves. This behavior is associated with poor clinical outcomes; therefore, it is critical to identify novel ligand-receptor interactions between nerves and cancer cells that support the process of perineural invasion. A proteomic profiler chemokine array was used to screen for nerve-derived factors s...
