WebFeb 11, 2024 · Zebrafish PGCs migrate within the embryo employing blebs and are directed by the chemokine Cxcl12a and its receptor Cxcr4b (26). When guided by the chemokine as well as when migrating in random directions in its absence, PGCs alternate between two distinct modes of behavior namely “run” and “tumbling” (27). WebChemokine receptors are seven-transmembrane proteins expressed on neutrophils, lymphocytes, dendritic cells, and many other cell types. They function to mediate migration of leukocytes to the sites of injury and infection in response to a gradient concentration of chemokines, a group of small proteins that specifically bind the chemokine receptors.

WebJan 31, 2024 · Chemokine receptors control the migration of many different cell types, including leukocytes, in response to specific chemokine ligands. Upon binding to chemokine, most of these receptors couple to the Gα i class of heterotrimeric G proteins, which, in turn, activate the cell motility machinery. WebThe chemokine gradient forms by diffusion between the cell migration channels and the cell loading chamber. The migration channels are designed as chemokine “sources”, from which the cheomokine will diffuse at predictable rates, dependent on the length, geometry, and cross section of the channels.
