Regulated on activation, normal T expressed, and secreted (RANTES)/CC ligand 5 (CCL5) participates in rheumatoid arthritis (RA) pathogenesis by facilitating leukocyte infiltration, however, its other pathological functions are not fully defined in RA. In the present study, we evaluated the effect of RANTES/CCL5 on tissue degrading enzymes matrix metalloproteinase-1 (MMP-1) and MMP-13 expression...
Chemokine CCL5/RANTES is highly expressed in cancer where it contributes to inflammation and malignant progression. In this study, we show that CCL5 plays a critical role in immune escape in colorectal cancer. We found that higher levels of CCL5 expression in human and murine colon tumor cells correlated with higher levels of apoptosis of CD8+ T cells and infiltration of T-regulatory cells (T(r...
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 ه...
Peritonitis is characterized by a coordinated influx of various leukocyte subpopulations. The pattern of leukocyte recruitment is controlled by chemokines secreted primarily by peritoneal mesothelial cells and macrophages. We have previously demonstrated that some chemokines may be also produced by human peritoneal fibroblasts (HPFB). Aim of our study was to assess the potential of HPFB in cult...
Aberrant energy metabolism is critical for cancer progression. Tumor-associated macrophages (TAMs) can stimulate tumor angiogenesis and enhance cancer metastasis; however, the metabolic interaction between cancer cells and macrophages characterized by lactate shuttles remains unclear. Here, we showed that lactate activated human macrophages to a TAM-like phenotype and stimulated the secretion o...
We previously reported that a gain-of-function -28G allele at the promoter SNP (-28C>G) in the CCL5 gene was associated with susceptibility to late-onset asthma in patients who developed asthma at age 40 or older. The clinical diagnosis of COPD includes emphysema and small airway disease, and upregulation of CCL5 has been described in the airways of patients with COPD. We hypothesized that the ...
Human memory CD4(+) T cells respond better to inflammatory CCLs/CC chemokines, CCL3 and CCL5, than naive CD4(+) T cells. We analyzed the regulatory mechanism underlying this difference. Memory and naive CD4(+) T cells expressed similarly high levels of CCR1; however, CCR5 was only expressed in memory CD4(+) T cells at low levels. Experiments using mAbs to block chemokine receptors revealed that...
• In vitro , lipofection of CCL5/CCL17 modifies the expression cytokines. The main driver these changes was entry foreign DNA into cytosol. vivo ECT pulses lead to high Ccl5 and Ccl17 after GET. GET CCL5 or CCL17 results in increased Cxcl9 Ifn? . are potent activators immune system CT26 tumor model. effectiveness immunotherapy highly correlates with degree type infiltrated cells tissue. Treatme...
RATIONALE Sialylation by α2,3-sialyltransferases has been shown to be a crucial glycosylation step in the generation of functional selectin ligands. Recent evidence suggests that sialylation also affects the binding of chemokines to their corresponding receptor. OBJECTIVE Because the chemokine receptors for Ccl5 and Ccl2 are important in atherogenic recruitment of neutrophils and monocytes, w...
CCL5/RANTES is a key proinflammatory chemokine produced by virus-infected epithelial cells and present in respiratory secretions of asthmatics. To examine the role of CCL5 in viral lung disease, we measured its production during primary respiratory syncytial virus (RSV) infection and during secondary infection after sensitizing vaccination that induces Th2-mediated eosinophilia. A first peak of...
