Usage and Biology

Chemokines are a family of small chemotactic cytokines, and the name is derived from their ability to induce directed chemotaxis in nearby responsive cells. All chemokines possess a number of conserved cysteine residues involved in intramolecular disulfide bond formation. Some chemokines can be induced during an immune response to recruit cells of the immune system to a site of infection, while others are considered homeostatic and are involved in controlling the migration of cells during normal processes of tissue maintenance or development. Chemokines are found in all vertebrates, some viruses and some bacteria.

GRO-beta/CXCL2 is produced by activated monocytes and neutrophils and expressed at sites of inflammation. It is a hematoregulatory chemokine, which, in vitro, suppresses hematopoietic progenitor cell proliferation. GRO-beta(5-73) shows a highly enhanced hematopoietic activity.

Results

We used the Transwell experiment combined with flow cytometry to verify the chemotactic ability of this chemokine on the THP1 cell line.(Fig.1)

Besides, we also tested the activity of six other chemokines.(Fig.2)
