Glucagon-like peptide-1 (GLP-1) promotes insulin release; however, the relationship between the GLP-1 signal and chronic pancreatitis is not well understood. Here we focus on chemokine (C-C motif) ligand 2 (CCL2) and its receptor (CCR2) axis, which regulates various immune cells, including macrophages, to clarify the mechanism of GLP-1-mediated insulin secretion in chronic pancreatitis in mice....
Chikungunya virus (CHIKV) and Ross River virus (RRV) are mosquito-transmitted alphaviruses that cause debilitating acute and chronic musculoskeletal disease. Monocytes are implicated in the pathogenesis of these infections; however, their specific roles are not well defined. To investigate the role of inflammatory Ly6ChiCCR2+ monocytes in alphavirus pathogenesis, we used CCR2-DTR transgenic mic...
Immature B cells are targeted to specific areas in the spleen, where a fraction of these cells receive signals that induce them to mature and participate in the immune response. In this study, we show that the C-C chemokine receptor 2 (CCR2) is transcribed in immature B cells, while its message is dramatically down regulated at the mature stage. CCR2 deficient cells exhibit upregulation of chem...

In this study, we show that the C-C chemokine receptor 2 (CCR2) is transcribed in immature B cells, while its message is dramatically down-regulated at the mature stage. CCR2-deficient cells exhibit up-regulation of che...
The identification of chemokine receptors as HIV-1 coreceptors has focused research on developing strategies to prevent HIV-1 infection. We generated CCR2-01, a CCR2 receptor-specific monoclonal antibody that neither competes with the chemokine CCL2 for binding nor triggers signaling, but nonetheless blocks replication of monotropic (R5) and T-tropic (X4) HIV-1 strains. This effect is explained...
A major barrier in hematopoietic gene function studies is posed by the laborious and time-consuming generation of knockout mice with an appropriate genetic background. Here we present a novel lentivirus-based strategy for the in situ generation of hematopoietic knockdowns. A short hairpin RNA (shRNA) was designed targeting murine CC-chemokine receptor 2 (CCR2), which was able to specifically bl...
Expression of CCR2, CXCR3 and CCR4 on CD4(+) T or CD8(+) T cells in blood and cerebrospinal fluid (CSF) for multiple sclerosis (MS) was measured by 3-color flow cytometry, and compared to blood from healthy controls and CSF from patients with other inflammatory neurological diseases (INDs). CD4(+)CXCR3(+)/CD4(+)CCR4(+) ratio (representing Th1/Th2 balance) was higher in both CSF and blood of MS ...
Both antiretroviral therapy and the human coreceptor polymorphism CCR2-V64I slow progression of human immunodeficiency virus type 1 (HIV-1) disease. To examine the effect of V64I on disease progression in patients receiving therapy, we determined CCR2 genotypes in the Women's Interagency HIV Study cohort. We studied 2047 HIV-1-infected women, most of whom initiated treatment during the study. N...
مقدمه: شبکه پیچیده کموکاین ها و رسپتور آن ها نقش مهمی در گسترش و متاستاز تومورها دارد. این مطالعه به بررسی میزان بیان mrna ی ccr2 و ccr5 و هم چنین سطح سرمی ccl2 و ccl5 در بیماران مبتلا به کارسینوم سلول های ترانزیشنال مثانه قبل و بعد از عمل tur می پردازد. مواد و روش ها: در این تحقیق پیش رو 40 نفر بیمار مرد مبتلا به transitional cell carcinoma (tcc) و 40 نفر مرد سالم وارد مطالعه شدند. نمونه های ...
Background: Macrophages expressing CC chemokine receptor 2 (CCR2) possess characteristics and performance akin to M1 polarized macrophages, which promote inflammation. Advanced heart failure (HF) patients with higher abundance of CCR2+ macrophages are more likely experience adverse remodeling. The precise mechanism in how they affect the progression dilated cardiomyopathy remains unknown. Metho...
