Chemokine sequestration by atypical chemokine receptors.
Leucocyte migration is essential for robust immune and inflammatory responses, and plays a critical role in many human diseases. Chemokines, a family of small secreted protein chemoattractants, are of fundamental importance in this process, directing leucocyte trafficking by signalling through heptahelical G-protein-coupled receptors expressed by the migrating cells. However, several mammalian ...
متن کاملChemokine blockade
Motoring to a signaling check-up T he Smad2 signaling protein is shuttled back to the membrane to check up on its receptor, according to Julie Batut, Michael Howell and Caroline Hill (Cancer Research UK, London). The check-ups ensure that intracellular signaling accurately refl ects the activation status of the membrane-bound receptor. Smad proteins are phosphorylated by and act downstream of T...
متن کاملThe role of chemokines and chemokine receptors in mycosis fungoides
Background: Chemokines are a family of cytokines initially characterized by their capacity to induce chemotaxis, or directed leukocyte migrations. These receptors are activated by chemotactic cytokines called chemokines. Interactions between chemokines and chemokine receptors also are involved in tumorigenesis, migration and invasion of lymphoma cells.Methods: An English literature search...
متن کاملChemokine receptors.
Chemokines mediate their multiple effects by binding to a variety of specific receptors, that comprise a subfamily of rhodopsin-like, 7-transmembrane domain receptors, coupled to G proteins. Some of these receptors serve as coreceptors for HIV, some of them could be expressed as markers for T lymphocyte functional differentiation. This review aims at summarising data on chemokine receptors, the...
متن کاملAn Investigation into the Effects of Joint Planning on Complexity, Accuracy, and Fluency across Task Complexity
The current study aimed to examine the effects of strategic planning, online planning, strategic planning and online planning combined (joint planning), and no planning on the complexity, accuracy, and fluency of oral productions in two simple and complex narrative tasks. Eighty advanced EFL learners performed one simple narrative task and a complex narrative task with 20 minutes in between. Th...
