Biochem/physiol Actions
I-TAC (Interferon-inducible T-cell α chemoattractant) is a chemokine which participates in recruitment of inflammatory cell. It binds to receptor CXCR3 (C-X-C motif chemokine receptor 3). I-TAC is associated with the severity of dengue.
Physical form
Lyophilized in 30% acetonitrile and 0.1% trifluoroacetic acid containing 1.25 mg of bovine serum albumin.
Analysis Note
The biological activity is measured by its ability to induce chemotaxis in IL-2 cultured human lymphocytes.

Dengue causes significantly more human disease than any other arboviruses. It causes a spectrum of illness, ranging from mild self-limited fever, to severe and fatal dengue hemorrhagic fever, as evidenced by vascular leakage and multifactorial hemostatic abnormalities. There is no

A new murine chemokine was identified in a search for glucocorticoid-attenuated response genes induced in the lung during endotoxemia. The first 73 residues of the predicted mature peptide are 71% identical and 93% similar to human CXCL11/IFN-inducible T cell alpha

We report preliminary characterization of a gene designated beta-R1, which is selectively expressed in response to interferon beta (IFN-beta) compared with IFN-alpha. In human astrocytoma cells, beta-R1 was induced to an equivalent extent by 10 IU/mL IFN-beta or 2500 IU/mL

H174 is a new member of the CXC-chemokine family. A cDNA probe containing the entire H174 coding region recognized a predominant inducible transcript of approximately 1.5 kb expressed in interferon (IFN) activated astrocytoma and monocytic cell lines. H174 message can

Chemokines are essential mediators of normal leukocyte trafficking as well as of leukocyte recruitment during inflammation. We describe here a novel non-ELR CXC chemokine identified through sequence analysis of cDNAs derived from cytokine-activated primary human astrocytes. This novel chemokine, referred
