Having an understanding of the properties of cytokines is essential for the immunologist, the researcher and the medical practitioner who need to understand immunologic diseases and immunological therapeutic approaches. Cytokines are redundant in their actions on target cells and promiscuous in their receptor reactions. (ED note: That is some cool use of English!) Moreover, many cells concomitantly produce several cytokines that have overlapping actions. Here this review provides conceptual framework to understand the intriguing aspects of the cytokine system.

Abstract PDF: PURPOSE: To evaluate the chemokine expression in children with a non-productive cough. MATERIALS AND METHODS: Six children with a non-productive cough who visited Yeungnam University Hospital were evaluated for the mRNA expression of interferon-gamma-inducible protein 10(IP-10), macrophage cationic protein 1 and 3 (MCP-1, 3), interleukin (IL)-8, regulated upon activation in normal T cells expressed and secreted (RANTES), eotaxin and growth-related oncogene-alpha (Gro-alpha) using the reverse transcription polymerase chain reaction. RESULTS: The chemokines IP-10 and MCP-3 were expressed in all samples. The chemokine RANTES was expressed in five cases, and IL-8 was expressed in three among them. However, eotaxin, Gro-alpha and MCP-1 were not expressed at all. The expression of chemokine MCP-3, RANTES and IL-8 were suppressed after the resolution of coughing in just one available case. CONCLUSION: The chemokines MCP-3, RANTES and IL-8 may contribute to airway inflammation in children with a non-productive cough, whereas IP-10 is of secondary importance in this condition.

Abstract PDF: Background
：The action of chemokines to the vascular inflammation plays a pathogenic role in the development and maintenance of hypertension. Materials and methods：In the present study, the expression of chemokine IL-8/CXCL8, MCP-1/CCL2 and RANTES/CCL5 was investigated in cultured vascular smooth muscle cells (VSMC) obtained from the thoracic aorta of normotensive Wister-Kyoto rat (WKY) and spontaneously hypertensive rat (SHR). We used real-time PCR and western blotting.
Result
：The expressions of IL-8/CXCL8, and MCP-1/CCL2 mRNA were stronger in VSMC from SHR than in WKY. However, the expression of RANTES/CCL5 was stronger in VSMC from WKY than in SHR. Expressions of CXCR1, CCR2, CD14 and PPARγ mRNA were stronger in VSMC from WKY than in SHR. Expressions of LPS-induced IL-8/CXCL8 and MCP-1/CCL2 mRNA were stronger in VSMC from SHR, but expression of LPS-induced RANTES/CCL5 was stronger in VSMC from WKY. A PPAR-γ ligand, 15-deoxy-Δ12, 14- prostaglandin J2 (15d-PGJ2) which possesses anti-inflammatory activity suppressed the expressions of LPS-induced IL-8/CXCL8, MCP-1/CCL2 and RANTES/CCL5 in VSMC from WKY and the expressions of LPS-induced MCP-1/CCL2 and RANTES/CCL5 expressions in SHR. But, the expression of LPS-induced IL-8/CXCL8 mRNA in SHR was increased by 15d- PGJ2. Angiotensin II (AngII) also induced IL-8/CXCL8 and MCP-1/CCL2 mRNA expressions in VSMC from SHR, but inhibited the expression of RANTES/CCL5 mRNA. Activities of LPS, or AngII-induced MAP kinases were stronger in VSMC from SHR than in WKY. Expression of AngII-induced IL-8/CXCL8 mRNA was associated with ERK phathway, and the expression of AngII-induced MCP-1/CCL2 mRNA was associated with p38 pathway, and the inhibition of RANTES/CCL5 mRNA by AngII was not associated with MAP Kinases pathways.
Conclusion
：Chemokine IL-8/CXCL8 and MCP-1/CCL2, not RANTES/CCL5, has a possibility to play a critical role in the pathogenesis of hypertension in the SHR.

Abstract PDF: BACKGROUND
Leptin is a 16-KDa non-glycosylated peptide hormone synthesized almost exclusively by adipocytes. The well-known function of leptin is regulation of food intake and energy expenditure. Leptin also plays a regulatory role in immune and inflammatory process including cytokine production. The purpose of this study was to investigate the effect of leptin on the expression of several chemokine genes(RANTES, IL-8, MCP-1, IP-10, Mig, MIP-1alpha, MIP-1beta, and GRO-alpha) in THP-1 cells. MATERIALS AND METHODS: Total RNA of THP-1 cells were prepared by Trizol method, and then stimulated with the leptin(250 ng/microliter) or LPS(100 ng/microliter). We examined the expression patterns of various chemokine mRNAs in THP-1 cell lines by RT-PCR and Northern blot. RESULTS: Leptin did not induce the expression of chemokine mRNAs in THP-1 cells. The expression patterns of RANTES, IL-8, MCP-1, IP-10, and Mig mRNAs in THP-1 cells stimulated with leptin and LPS simultaneously was almost same to the patterns of LPS alone-induced chemokine mRNAs. RANTES mRNA expression was independent on the concentrations of leptin. Although leptin did not have strong effect on the expression of RANTES, IL-8, MCP-1, IP-10, Mig, MIP-1alpha, MIP-1beta, and GRO-alpha mRNAs in THP-1 cells, leptin could induce the expression of long isoform of leptin receptor(OB-RL) mRNA, and its expression was elevated in simultaneous stimulation of leptin and LPS. CONCLUSION: These data suggest that leptin is able to induce OB-RL in THP-1 cells, however, leptin has little effect on the expression of pro-inflammatory chemokine genes.
