We evaluated the role of the CXCL12/CXCR4 (C-X-C motif chemokine ligand 12/C-X-C chemokine receptor type 4) axis in aggrecanase-mediated cartilage degradation, and explored the underlying mechanism in a post-traumatic osteoarthritis rat model. Expression of CXCL12/CXCR4 and ADAMTS-5 was analyzed in the knees of osteoarthritic and non-arthritic rats using Western blot, ELISA, immunohistochemistr...
زمینه و هدف: تاکنون در مطالعات مختلفی بهبررسی موبیلیزاسیون سلولهای بنیادی خونساز بهمنظور پیوند و اهمیت سیگنالهای -آدرنرژیکی در القای این فرآیند، پرداخته شده است. با این وجود، اطلاعات کمی درباره نحوه اثر این سیگنالها در موبیلیزاسیون سلولهای بنیادی خونساز، موجوداست. کموکاین sdf-1 که توسط سلولهای بنیادی مزانشیمی مغز استخوان انسان تولیدمیگردد، در روند موبیلیزاسیون سلولهای بنیادی خونساز،...
BACKGROUND A devastating late injury caused by radiation is pulmonary fibrosis. This risk may limit the volume of irradiation and compromise potentially curative therapy. Therefore, development of a therapy to prevent this toxicity can be of great benefit for this patient population. Activation of the chemokine receptor CXCR4 by its ligand stromal cell-derived factor 1 (SDF-1/CXCL12) may be imp...
Previously we defined a pathway of transforming growth factor beta (TGF-beta) and stromal cell-derived factor-1/CXC chemokine ligand 12 (SDF-1alpha/CXCL12) dependent migration of adult haematopoietic stem and progenitor cells (HPC) towards glioma cells in vitro and their homing to experimental gliomas in vivo. Hypoxia is a critical aspect of the microenvironment of gliomas and irradiation is an...
Blockade of SDF-1 after irradiation inhibits tumor recurrences of autochthonous brain tumors in rats
BACKGROUND Tumor irradiation blocks local angiogenesis, forcing any recurrent tumor to form new vessels from circulating cells. We have previously demonstrated that the post-irradiation recurrence of human glioblastomas in the brains of nude mice can be delayed or prevented by inhibiting circulating blood vessel-forming cells by blocking the interaction of CXCR4 with its ligand stromal cell-der...
CXCR4, the receptor for the chemokine stromal cell-derived factor (SDF)-1 (CXCL12), is involved in lymphocyte trafficking. We have demonstrated previously that it is required for invasion of lymphoma cells into tissues and therefore essential for lymphoma metastasis. CXCR4 is also expressed by carcinoma cells, and CXCR4 antibodies were recently shown to reduce metastasis of a mammary carcinoma ...
