Abstract
Chronic pain affects patients' physical and psychological health and quality of life, entailing a tremendous public health challenge. Currently, drugs for chronic pain are usually associated with a large number of side effects and poor efficacy. Chemokines in the neuroimmune interface combine with their receptors to regulate inflammation or mediate neuroinflammation in the peripheral and central nervous system. Targeting chemokines and their receptor-mediated neuroinflammation is an effective means to treat chronic pain. In recent years, growing evidence has shown that the expression of chemokine ligand 2 (CCL2) and its main chemokine receptor 2 (CCR2) is involved in its occurrence, development and maintenance of chronic pain. This paper summarises the relationship between the chemokine system, CCL2/CCR2 axis, and chronic pain, and the CCL2/CCR2 axis changes under different chronic pain conditions. Targeting chemokine CCL2 and its chemokine receptor CCR2 through siRNA, blocking antibodies, or small molecule antagonists may provide new therapeutic possibilities for managing chronic pain.

Abstract
AIMS Hydrogen sulfide (H2S) prevents endothelial cells injury. However, the complicated mechanism of sodium hydrosulfide (NaHS, a donor that produces H2S) which inhibits the endothelial cells injury which correlated the activation of neutrophil in the type 1 diabetes mellitus (T1DM) rats has not been previously investigated. METHODS AND RESULTS In the experiment, the T1DM animal model was established, the IL-1β, IL-8 were determined by western blotting and ELISA, the expressions of the Bax and Bcl-2 of endothelial cells and the CXCR2, CSE, phosphor-IκBα and NF-kB of neutrophils were measured by western blotting. Additionally, the concentration of serum dsDNA was tested by PicoGreen commercial Kits, changes in the H2S concentration of neutrophils were determined by Multiskan spectrum microphate spectrophotometer, the cellular ROS levels of neutrophils were detected by DCFH-DA staining and flow cytometry. The IL-1β, IL-8 concentration and expression increased, the endothelial cells injury which stimulated by high glucose and the concentration of dsDNA in serum increased, the expression of CXCR2, phosphor-IκBα and NF-kB increased while the expression of CSE and concentration of H2S decreased in neutrophils in the T1DM group compared to the control group. NaHS significantly inhibited the injury of endothelial cell, the production of ROS in neutrophils, reversed the expressions of CXCR2, CSE, phosphor-IκBα and NF-κB and decreased concentration of dsDNA in serum which were caused by T1DM. CONCLUSIONS Our results demonstrated that the donor of H2S inhibits endothelial cells injury and neutrophils activation via the IL-8/CXCR2/ROS/NF-κB axis in T1DM rat.

Abstract
Oncolytic viruses (OVs) selectively replicate in and destroy cancer cells resulting in anti-tumor immunity. However, clinical use remains a challenge because of virus clearance upon intravenous delivery. OV packaging using a nanomedicine approach could overcome this. Here we encapsulate an oncolytic adenovirus (Ad[I/PPT-E1A]) into CCL2-coated liposomes in order to exploit recruitment of CCR2-expressing circulating monocytes into tumors. We demonstrate successful encapsulation of Ad[I/PPT-E1A] into CCL2-coated liposomes that were preferentially taken up by CCR2-expressing monocytes. No complex-related toxicities were observed following incubation with prostate tumor cells and the encapsulation did not affect virus oncolytic activity in vitro. Furthermore, intravenous administration of our nanomedicine resulted in a significant reduction in tumor size and pulmonary metastasis in prostate cancer-bearing mice whereby a 1000-fold less virus was needed compared to Ad[I/PPT-E1A] alone. Taken together our data provide an opportunity to target OVs via circulation to inaccessible tumors using liposome-assisted drug delivery.

Abstract
The development of atherosclerosis therapy is hampered by the lack of molecular imaging tools to identify the relevant biomarkers and determine the dynamic variation in vivo. Here, we show that a chemokine receptor 2 (CCR2) targeted gold nanocluster conjugated with extracellular loop 1 inverso peptide (AuNC-ECL1i) determines the initiation, progression and regression of atherosclerosis in apolipoprotein E knock-out (ApoE-/-) mouse models. The CCR2 targeted 64Cu-AuNC-ECL1i reveals sensitive detection of early atherosclerotic lesions and progression of plaques in ApoE-/- mice. CCR2 targeting specificity was confirmed by the competitive receptor blocking studies. In a mouse model of aortic arch transplantation, 64Cu-AuNC-ECL1i accurately detects the regression of plaques. Human atherosclerotic tissues show high expression of CCR2 related to the status of the disease. This study confirms CCR2 as a useful marker for atherosclerosis and points to the potential of 64Cu-AuNC-ECL1i as a targeted molecular imaging probe for future clinical translation.

Abstract
BACKGROUND We previously demonstrated that H. pylori infection leads to increased induction of regulatory T cells in local and systemic immune compartments. Here, we investigate the role of CCR2 in the tolerogenic programing of dendritic cells in a mouse model of H. pylori infection. MATERIALS AND METHODS CCR2 deficient (CCR2KO) mice and wild-type (Wt) mice infected with H. pylori SS1 strain were analyzed by qPCR and FACS analysis. In vitro, bone marrow-derived DC on day 6 from CCR2KO and Wt mice cocultured with or without H. pylori were examined to determine the impact of CCR2 signaling on dendritic cells function by qPCR, ELISA, and FACS analyses. RESULTS Acute H. pylori infection was associated with a threefold increase in CCR2 mRNA expression in the gastric mucosa. H. pylori-infected CCR2KO mice exhibited a higher degree of mucosal inflammation, that is, increased gastritis scores and pro-inflammatory cytokine mRNA levels, but lower degree of H. pylori gastric colonization compared to infected Wt mice. Peripheral H. pylori-specific immune response measured in the CCR2KO spleen was characterized by a higher Th17 response and a lower Treg response. In vitro, CCR2KO bone marrow-derived DC was less mature and shown a lower Treg/Th17 ratio. Moreover, blockade of CCR2 signaling by MCP-1 neutralizing antibody inhibited H. pylori-stimulated bone marrow-derived DC maturation. CONCLUSIONS Our results indicate that CCR2 plays an essential role in H. pylori-induced immune tolerance and shed light on a novel mechanism of CCR2-dependent DC Treg induction, which appears to be important in maintaining mucosal homeostasis during H. pylori infection.
