شواهدی وجود دارد که نشن می دهد، اسید آمینه های تحریکی در فرآیند انتقال عصبی در سیستم عصبی مرکزی و اثرات بی دردی مرفین دخالت دارند. (47) در مطالعه حاضر اثرات آنتاگونیست های رسپتور (dap5,dap7)nmda بر روی بی دردی ناشی از مرفین در تست فرمالین مورد مطالعه قرار گرفته است . تزریق زیر جلدی فرمالین رقیق شده، امروزه به عنوان یک مدل درد وسیعا مورد مطالعه قرار می گیرد. دوره زمانی معمول پاسخ به فرمالین دو ف...

CXC chemokine receptor 4 (CXCR4) is a G protein-coupled receptor (GPCR) located on the cell surface that signals upon binding the chemokine stromal derived factor-1 (SDF-1; also called CXCL 12). CXCR4 promotes neuroblastoma proliferation and chemotaxis. CXCR4 expression negatively correlates with prognosis and drives neuroblastoma growth and metastasis in mouse models. All functions of CXCR4 re...

Recent evidence suggests that C-X-C chemokine receptor type 4 (CXCR4) heteromerizes with α1A/B-adrenoceptors (AR) and atypical chemokine receptor 3 (ACKR3) and that CXCR4:α1A/B-AR heteromers are important for α₁-AR function in vascular smooth muscle cells (VSMC). Structural determinants for CXCR4 heteromerization and functional consequences of CXCR4:α1A/B-AR heteromerization in intact arteries,...

CXC chemokine receptor 4 (CXCR4) is an essential regulator for homing and maintenance of hematopoietic stem cells within the bone marrow niches. Analysis of clinical implications of bone marrow CXCR4 expression in patients with acute myeloid leukemia showed not only higher CXCR4 expression was an independent poor prognostic factor, irrespective of age, white blood cell counts, cytogenetics, and...

The chemokine receptor CXCR4 is expressed in many cancers where it may regulate tumor cell growth and migration. The role of CXCR4 in cancer will depend on it being in an activated, signaling state. To better define the significance of CXCR4 expression in cancer, we developed an antibody that can distinguish CXCR4 phosphorylated on serine 339, a residue previously identified as a site for ligan...

UNLABELLED CXCR4 is a chemokine receptor that mediates invasion and metastasis. CXCR4 expression is transcriptionally regulated in cancer cells and is associated with aggressive prostate cancer phenotypes. Previously, we and others have shown that the transcription factor ERG regulates CXCR4 expression in prostate cancer cells and that androgens modulate CXCR4 expression via increasing ERG expr...

The chemokine stromal derived factor-1alpha (SDF-1alpha) has been implicated recently in the chemotaxis of primitive human hematopoietic cells, suggesting that pluripotent human stem cells express the SDF-1alpha receptor, CXCR4. By using flow cytometry and confocal microscopy, we have identified and isolated primitive subsets of human CXCR4(+) and CXCR4(-) cells. Distinctions in the progenitor ...

Acute myeloid leukemia originates from leukemia-initiating cells that reside in the protective bone marrow niche. CXCR4/CXCL12 interaction is crucially involved in recruitment and retention of leukemia-initiating cells within this niche. Various drugs targeting this pathway have entered clinical trials. To evaluate CXCR4 imaging in acute myeloid leukemia, we first tested CXCR4 expression in pat...

introduction: a number of potential cell adhesion molecules, which mediate essential cell-to-cell or cell-to-matrix interactions, are expressed on the surface of cd34+ hematopoietic progenitor cells (hpcs), including integrins, cd44, and cxcr4. these molecules are essential for homing process. in this study, we compared the changes of expression of cd44 and cxcr4 on the cd34+ hematopoietic prog...
