Recently we found four cytokine-induced neutrophil chemoattractants, CINC-1, CINC-2 alpha, CINC-2 beta and CINC-3/macrophage inflammatory protein 2 (MIP-2), in conditioned medium of granulation tissue obtained from carrageenin-induced inflammation in rats [Nakagawa, H., Komorita, N., Shibata, F., Ikesue, A., Konishi, K., Fujioka, M. & Kato, H. (1994) Biochem. J. 301, 545-550]. In the present report, we describe recombinant production of CINC-2 alpha, CINC-2 beta and CINC-3 in Escherichia coli, and biological properties of these chemokines. Neutrophil chemotactic activities of CINC-2 alpha and 2 beta in vitro were the same as the activity of CINC-1. CINC-3 had an activity comparable to other CINCs, but showed a decrease at high concentrations. Stimulation of neutrophils with CINCs induced an increase in intracellular [Ca2+] dose-dependently. CINC-3 was more potent than the other CINCs and still induced an increase in intracellular [Ca2+] in rat neutrophils stimulated first with other CINCs. CINC-2 alpha, CINC-2 beta and CINC-3 induced a comparable response to CINC-1 in the release of cathepsin G from rat neutrophils. Injection of CINC-2 alpha, 2 beta and 3 into preformed air-pouch on the back of rat induced infiltration of neutrophils to an extent similar to that caused by the injection of CINC-1. These data indicate CINC-2 alpha, 2 beta and 3 as well as CINC-1 are chemoattractants specific for neutrophil in vivo.

UI MeSH Term Description Entries
D008070 Lipopolysaccharides Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed) Lipopolysaccharide,Lipoglycans

D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D002403 Cathepsins A group of lysosomal proteinases or endopeptidases found in aqueous extracts of a variety of animal tissues. They function optimally within an acidic pH range. The cathepsins occur as a variety of enzyme subtypes including SERINE PROTEASES; ASPARTIC PROTEINASES; and CYSTEINE PROTEASES. Cathepsin
