Urinary Evaluation of the Balance Between the Soluble Interferon-Gamma Receptor (IFN-γR1) and the Interleukin-4 Receptor (IL-4Rα) in Children with Vesicoureteral Reflux
Journal of immunoassay & immunochemistry, 2009Co-Authors: Yoshihiro Okamoto, Mayuri Tanaka, Takuhito Nagai, Yoshimitsu Gotoh, Naoya Fujita, Takashi Fukui, Toshiyuki MasuzawaAbstract:Abstract We planned to investigate the urinary soluble cytokine Receptor profile in patients with vesico-ureteric reflux (VUR). The urine levels of soluble interferon-γ Receptor R1 (sIFN-γR) and soluble Interleukin-4 Receptor α (sIL-4R) were measured using an ELISA technique. The urine levels of sIFN-γR in the patients with VUR were significantly higher than those in the healthy controls (p

Urinary evaluation of the balance between soluble interferon-gamma Receptor (IFN-γR1) and Interleukin-4 Receptor (IL-4Rα)
International Immunopharmacology, 2008Co-Authors: Yoshihiro Okamoto, Takuhito Nagai, Yoshimitsu Gotoh, Naoya Fujita, Takashi Fukui, Izumi Nakajo, Kyoko Seta, Toshiyuki MasuzawaAbstract:To elucidate the usefulness of the simultaneous analysis of multiple kinds of soluble cytokine Receptors in urine specimens, we determined the levels of both the soluble interferon-gamma Receptor α chain (sIFN-γR1, Th1-type cytokine Receptor) and the soluble Interleukin 4-Receptor α chain (sIL-4Rα, Th2-type cytokine Receptor) in the urine of healthy subjects as reference values and preliminarily applied this method to evaluate patients with diarrhea positive (D+) hemolytic uremic syndrome (HUS) as the diagnostic parameters. The urinary sIFN-γR levels of children were significantly lower than those of adults (p < 0.01, n = 107). On the other hand, there was no significant difference between the urine sIL-4R levels of adults and children. Statistical correlation between sIFN-γR and sIL-4R values was not observed (p = 0.705). On the day of onset of HUS, the urine sIFN-γR levels of the patients (n = 6) with HUS were higher than those of the healthy control group (n = 67) (p < 0.01); however, there was no significant difference in the sIL-4R levels between both groups. The urine evaluation of the balance between the soluble cytokine Receptors might be informative for the immune states of HUS patients.

Increased levels of soluble Interleukin-4 Receptor in the sera of patients with visceral leishmaniasis.
The Journal of infectious diseases, 1999Co-Authors: David K. Sang, John H. Ouma, Chandy C. John, Christopher C. Whalen, Christopher L. King, Adel A. F. Mahmoud, Frederick P. HeinzelAbstract:Kenyan subjects with visceral leishmaniasis were examined for evidence of increased production of soluble Interleukin-4 Receptor (sIL-4R). Soluble IL-4R regulates the bioactivity of IL-4, a cytokine important in mediating progressive forms of leishmaniasis. Persons with visceral leishmaniasis sustained 8- to 10-fold more circulating sIL-4R compared with Papua New Guinea residents with documented filariasis or uninfected Kenyan and North American subjects. Soluble IL-2R concentrations were elevated nonspecifically in both visceral leishmaniasis and filariasis patients. These findings are significant given that IL-4 induces sIL-4R in mice, and treatment with recombinant sIL-4R cures progressive murine leishmaniasis dependent on IL-4 bioactivity. Further studies are indicated to determine whether the immunologic detection of IL-4 produced in human visceral leishmaniasis is obscured because of sequestration by soluble Receptor and whether the production of sIL-4R is relevant to the pathogenesis of visceral leishmaniasis.

Soluble Interleukin-4 Receptor in atopic children.
International archives of allergy and immunology, 1995Co-Authors: U. Schauer, M. Schmitt, S. Müller, Karlheinz Dr Enssle, R. Kurrle, U. Sundermann, A. Bender, Ulrich Wahn, Christian H.l. RiegerAbstract:The levels of natural soluble Interleukin-4 Receptor (shuIL-4R) were determined in the peripheral blood of 29 children with stable asthma, 10 children with asthma and acute respiratory infection, 11 healthy children with acute airway infection and 31 healthy controls. Healthy controls revealed the highest levels (median 1,082 pg/ml, range 524–1,900 pg/ml); which differed significantly from levels obtained with the blood of stable asthmatics (p

Healthy controls revealed the highest levels (median 1,082 pg/ml, range 524-1,900 pg/ml); which differed significantly from levels obtained with the blood of stable asthmatics (p < 0.01, median 658 pg/ml, range 329-1288 pg/ml), patients with asthma and acute respiratory infection (p < 0.01, median 663 pg/ml, range 0-1,250 pg/ml) and patients with respiratory infection alone (p < 0.01, median 674 pg/ml, range 466-1,110 pg/ml). In contrast, there was no significant difference in shuIL-4R content of cord blood obtained from newborns with a high or low risk of atopy. Additional analysis of Interleukin-4 Receptor (huIL-4R) on cultured lymphocytes from 13 stable asthmatic children and 14 healthy children indicated higher expression on CD4 cells (p < 0.05, median 2.2%, range 0.8-7.8%) compared to healthy controls (median 1.3%, range 0.7-3.3%). Therefore, diminished shuIL-4R concentrations in plasma may be related to inflammatory states but not specifically to atopy. The results support the notion that huIL-4R expressed on the cell surface may be regulated differently from the soluble form.
