CCR7

Chemokine receptors are found on the surface of certain cells that interact with chemokines. They have a 7-transmembrane (7TM) structure and couples to G-protein for signal transduction within a cell[1] (Figure 1). Following interaction with their specific chemokine ligands, chemokine receptors trigger a flux inintracellular calcium (Ca2+) ions which initiate the onset of chemotaxis that traffics the cell to a desired location (Figure 2).

Figure 1. typical structure of a chemokine receptor.

Figure 2. the mechanism of interaction between chemokine and chemokine receptor.

Under the circumstance of inflammation, various kinds of cytokines, including chemokines, are released by the lesions. Guided by the chemokines, cells expressing chemokine receptors move towards the lesions where they can function better. [2] What’s more, different diseases would release different pool of chemokines, which would recruit different effector cells.[http://2016.igem.org/File:T--SYSU-MEDICINE--project-diseasse-table-chemokine.pdf See our disease talbe-chemokine]
