Structural basis of chemokine receptor function--a model for binding affinity and ligand selectivity.
Chemokine receptors play fundamental roles in human physiology from embryogenesis to inflammatory response. The receptors belong to the G-protein coupled receptor class, and are activated by chemokine ligands with a range of specificities and affinities that result in a complicated network of interactions. The molecular basis for function is largely a black box, and can be directly attributed t...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...

The chemokine receptor CXCR4 has multiple critical functions in normal physiologies including embryonic development of the cardiovascular, hemopoietic and central nervous systems. It has also been implicated in disease pathologies such as HIV infection, cancer metastasis, leukemia progression and rheumatoid arthritis and is fueling the search for small molecule CXCR4 antagonists as a means for ...
متن کاملPathways for internalization and recycling of the chemokine receptor CCR5.
M-tropic human immunodeficiency virus (HIV-1) strains enter the cell after interaction with their receptors, CD4 and the G-protein-coupled chemokine receptor CCR5. The number of cell surface CCR5 molecules is thought to be important in determining the infection rate for HIV. Cell surface CCR5 is dependent on the rate of receptor internalization and recycling. Internalization of G-protein-couple...
متن کاملEffects of CC chemokine receptor 5 (CCR5) inhibitors on the dynamics of CCR5 and CC-chemokine-CCR5 interactions.
BACKGROUND This study aimed to examine how CC chemokine receptor 5 (CCR5) inhibitors (aplaviroc [APL], TAK779 and maraviroc [MVC]) interact with CCR5 and affect its dynamics and physiological CC-chemokine-CCR5 interactions. METHODS A yellow fluorescent protein (YFP)-tagged CCR5-expressing U373-MAGI cell line was generated and a stable CCR5-expressing clonal population, (YFP)CCR5-UM16, was pre...
