1.Determination of IL-1beta, IL-4 and IL-10 contents in the seminal plasma of infertile patients and its clinical value.
National Journal of Andrology 2004;10(11):851-854
OBJECTIVETo observe the relationship between the contents of interleukin-1beta (IL-1beta), interleukin-4 (IL-4) and interleukin-10 (IL-10) in the seminal plasma of infertile males and sperm function indexes.
METHODSBy radioimmunoassay (RIA), we determined the contents of IL-1beta, IL-4 and IL-10 in the seminal plasma of 126 infertile and 20 normal males. According to the sperm count, the infertile were divided into three groups: Groups A (sperm count > or = 20 x 10(6)/ml), B (sperm count < 20 x 10(6)/ml) and C (azoospermia). Based on sperm vitality and motility, Group A was subdivided into a normal and abnormal vitality group and a normal and decreased motility group. In line with the serum results of antisperm antibody (AsAb) and semen WBC, the infertile males were divided into AsAb positive and negative, and WBC semen and non-WBC semen groups. According to the assay results of normal males, Groups A and B were each subdivided into normal and decreased groups of sperm penetrating power, intact acrosome rate and terminal swelling rate.
RESULTSThe content of IL-1beta in the seminal plasma of the infertility group was obviously higher, but the content of IL-4, IL-10 significantly lower than that of the normal group (P < 0.01). In the infertility group, there existed significant differences in the contents of IL-1beta, IL-4, IL-10 in seminal plasma between the WBC and non-WBC semen groups, as well as between the AsAb positive and negative groups (P < 0.05 or P < 0.01); and the same was true for the content of IL-4 between the normal and decreased groups of sperm vitality, motility, penetrating power, intact acrosome rate, and terminal swelling rate (P < 0.05 or P < 0.01).
CONCLUSIONThe contents of IL-1beta, IL-4 and IL-10 in seminal plasma are closely related to male reproduction. The increase or decrease of the contents reflects the state of immunity and infection of the reproductive system, and influences sperm functions.

2.Association between serum fatty acid composition and innate immune markers in healthy adults.
Nutrition Research and Practice 2016;10(2):182-187
BACKGROUND/OBJECTIVES: Supplementation with n-3 polyunsaturated fatty acids (PUFAs) has been shown to generally decrease levels of innate immune markers and inflammatory cytokines, but the specific associations between blood levels of PUFAs and those of innate immune markers have not been investigated. Thus, the present study was conducted to test the hypothesis that innate immune markers as well as cytokines are negatively associated with n-3 PUFAs but positively associated with n-6 PUFAs in healthy adults. MATERIALS/METHODS: One hundred sixty-five healthy Korean adults aged 25-70 years old were included in this cross-sectional study. RESULTS: Serum levels of n-3 PUFAs, such as 18:3n3, 20:5n3, 22:5n3, and 22:6n3 were negatively correlated with eosinophil and basophil counts and TNF-α, IFN-γ, IL-4, and IL-10 levels. Multivariate analysis also showed that serum levels of n-3 PUFAs were negatively associated with monocyte, eosinophil, and basophil counts and TNF-α, IFN-γ, IL-4, and IL-12 levels. Additionally, the ratio of 20:4n6 to 20:5n3 was positively correlated with eosinophil counts and associated with TNF-α, IFN-γ, and IL-4 levels. However, NK cell activity was not associated with serum fatty acid composition. CONCLUSIONS: Innate immune markers such as eosinophil, monocyte, and basophil counts were inversely associated with serum levels of n-3 PUFAs, but were positively associated with the 20:4n6/20:5n3 ratio in this population.

3.Gene Expression Profiling of Meningioma by cDNA Chip.
Journal of Korean Neurosurgical Society 2004;35(6):560-568
OBJECTIVE: The current progress of the molecular biological study is in the situation of documentation of relation between the tumor development and the gene mutation. We report an analysis of gene expression profiling of meningioma by cDNA chip. METHODS: Meningioma, tumor attached dura and normal dura were obtained during surgery. RNA was extracted from each specimen and cDNA microarray was done. After that, we confirmed the reliability of results from the microarray technique by RT-PCR. RESULTS: We examined the expression of the tumor related gene by cDNA chip. The genes showing two fold changes in the expression were analyzed to find the difference between two groups. The analysis of the tumor and tumor attached dura indicated that the expression of twenty four genes were increased and seventeen genes were decreased in the tumor. The analysis of the gene expression of tumor and normal dura showed increase in twenty seven genes and decrease in thirty one genes. Nine genes in the tumor showed more increase than those in the tumor attached dura and the normal dura. We performed RT-PCR using cytokines to confirm the reliability of the microarray result. CONCLUSION: The cDNA chip contributes as a good laboratory method to check various gene expression of the meningioma and the dura. In the future, the relationship between the expression of IL-1beta, IL-4, IL-6, IL-8, and the function of each gene are required to investigate.

Idiopathic interstitial pneumonia (IIP) is characterized by varying degrees of interstitial fibrosis. IL-13 and IL-4 are strong inducers of tissue fibrosis, whereas IFN-gamma has antifibrotic potential. However, the roles of these substances in IIP remain unknown. IL-13, IL-4, and IFN-gamma were measured in the BAL fluid of 16 idiopathic pulmonary fibrosis (IPF) patients, 10 nonspecific interstitial pneumonia (NSIP) patients, and 8 normal controls. The expression of IL-13 and IL-13Ralpha1/alpha2 in lung tissues was analyzed using ELISA and immunohistochemistry. IL-13 levels were significantly higher in IPF patients than the others (P<0.05). IL-4 levels were higher in both IPF and NSIP patients than in normal controls (P<0.05), and IFN-gamma levels were lower in NSIP patients than in normal controls (P=0.047). IL-13 levels correlated inversely with FVC% (r=-0.47, P=0.043) and DLCO% (r=-0.58, P=0.014) in IPF and NSIP patients. IL-13 was strongly expressed in the smooth muscle, bronchial epithelium, alveolar macrophages and endothelium of IPF patients. IL-13Ralpha1, rather than IL-13Ralpha2, was strongly expressed in the smooth muscle, bronchial epithelium, and endothelium of IPF patients. IL-13 and its receptors may contribute to the pathogenesis of fibrosis in IIP and appear to be related to the severity of the disease.

OBJECTIVETo study the concentrations of IL-4 and IL-13 in bronchoalveolar lavage fluid (BALF) in neonates with respiratory distress syndrome (RDS) and concurrent ventilator-associated pneumonia (VAP).
METHODSSixty-eight neonates with RDS undergoing mechanical ventilation for over 48 hrs were enrolled. IL-4 and IL-13 levels in BALF were measured using ELISA 1, 72 and 96 hrs after mechanical ventilation. The results were compared between the neonates with concurrent VAP (n=37) and without (n=31).
RESULTSThe levels of BALF IL-4 96 hrs after ventilation in the VAP group (35.34+/-1.78 ng/mL) were significantly higher than those in the non-VAP group (13.69+/-2.47 ng/mL, P<0.05). The levels of BALF IL-13 96 hrs after ventilation in the VAP group (33.74+/-2.74 ng/mL) also increased significantly compared with those in the non-VAP group (13.50+/-3.81 ng/mL) (P<0.05). There were significant differences in BALF IL-4 and IL-13 levels between 1 hr and 96 hrs in the VAP group (P<0.05).
CONCLUSIONSBALF IL-4 and IL-13 levels increase in neonates with RDS and concurrent VAP. IL-4 and IL-13 may involve in the regulation of the inflammatory immune response.

Aeriscardovia aeriphila, also known as Bifidobacterium aerophilum, was first isolated from the caecal contents of pigs and the faeces of cotton-top tamarin. Bifidobacterium species play important roles in preventing intestinal infections, decreasing cholesterol levels, and stimulating the immune system. In this study, we isolated a strain of bacteria from the duodenal contents of broiler chickens, which was identified as A. aeriphila, and then evaluated the effects of A. aeriphila on growth performance, antioxidant functions, immune functions, and gut microbiota in commercial broiler chickens. Chickens were orally gavaged with A. aeriphila (1×109 CFU/mL) for 21 d. The results showed that A. aeriphila treatment significantly increased the average daily gain and reduced the feed conversion ratio (P<0.001). The levels of serum growth hormone (GH) and insulin-like growth factor 1 (IGF-1) were significantly increased following A. aeriphila treatment (P<0.05). Blood urea nitrogen and aspartate aminotransferase levels were decreased, whereas glucose and creatinine levels increased as a result of A. aeriphila treatment. Furthermore, the levels of serum antioxidant enzymes, including catalase (P<0.01), superoxide dismutase (P<0.001), and glutathione peroxidase (P<0.05), and total antioxidant capacity (P<0.05) were enhanced following A. aeriphila treatment. A. aeriphila treatment significantly increased the levels of serum immunoglobulin A (IgA) (P<0.05), IgG (P<0.01), IgM (P<0.05), interleukin-1 (IL-1) (P<0.05), IL-4 (P<0.05), and IL-10 (P<0.05). The broiler chickens in the A. aeriphila group had higher secretory IgA (SIgA) levels in the duodenum (P<0.01), jejunum (P<0.001), and cecum (P<0.001) than those in the control group. The messenger RNA (mRNA) relative expression levels of IL-10 (P<0.05) and IL-4 (P<0.001) in the intestinal mucosa of chickens were increased, while nuclear factor-κB (NF-κB) (P<0.001) expression was decreased in the A. aeriphila group compared to the control group. Phylum-level analysis revealed Firmicutes as the main phylum, followed by Bacteroidetes, in both groups. The data also found that Phascolarctobacterium and Barnesiella were increased in A. aeriphila-treated group. In conclusion, oral administration of A. aeriphila could improve the growth performance, serum antioxidant capacity, immune modulation, and gut health of broilers. Our findings may provide important information for the application of A. aeriphila in poultry production.

PURPOSE: Calcium ionophore (CI) is used to generate dendritic cells (DCs) from progenitor cells, monocytes, or leukemic cells. The aim of this study was to determine the optimal dose of CI and the appropriate length of cell culture required for acute myeloid leukemia (AML) cells and to evaluate the limitations associated with CI. MATERIALS AND METHODS: To generate leukemic DCs, leukemic cells (4 x 10(6) cells) from six AML patients were cultured with various concentrations of CI and/or IL-4 for 1, 2 or 3 days. RESULTS: Potent leukemic DCs were successfully generated from all AML patients, with an average number of 1.2 x 10(6) cells produced in the presence of CI (270 ng/ml) for 2 days. Several surface molecules were clearly upregulated in AML cells supplemented with CI and IL-4, but not CD11c. Leukemic DCs cultured with CI had a higher allogeneic T cell stimulatory capacity than untreated AML cells, but the addition of IL-4 did not augment the MLR activity of these cells. AML cells cultured with CI in the presence or absence of IL-4 showed increased levels of apoptosis in comparison to primary cultures of AML cells. CONCLUSION: Although CI appears to be advantageous in terms of time and cost effectiveness, the results of the present study suggest that the marked induction of apoptosis by CI limits its application to the generation of DCs from AML cells.

OBJECTIVETo study the regulatory role of bacterial lipopolysaccharide (LPS ) in the development of bronchial asthma by examining the effects of LPS on serum IL-4, serum IL-8 and pulmonary vascular endothelial growth factor (VEGF) expression in mice with asthma.
METHODSTwenty-seven BALB/c mice were randomly assigned into control, asthma and LPS-treated asthma groups (n=9 each). Serum IL-4 and IL-8 concentrations were measured using ELISA. VEGF expression in lung tissues was examined using the immunohistochemical method.
RESULTSSerum IL-4 and IL-8 concentrations in the asthma group were significantly higher than in the control group (P<0.05). LPS treatment significantly decreased serum IL-4 and IL-8 concentrations compared with the asthma group (P<0.05), although levels were significantly higher than in the control group (P<0.05). Airway VEGF expression in the asthma group was significantly higher than in the control group (P<0.05). LPS treatment significantly decreased airway VEGF expression compared with the asthma group (P<0.05), although concentrations remained higher than in the control group (P<0.05).
CONCLUSIONSLPS can decrease serum IL-4, serum IL-8 and pulmonary VEGF expression in mice with asthma, and thus can possibly reduce both airway inflammation and airway vascular remodeling.

9.Study on expression of cytokines mRNA induced by B7-1-transfected Raji and Jurkat cells.
Journal of Experimental Hematology 2002;10(4):322-326
To investigate the function of B7 co-stimulator in activation and differentiation of T cell, B7 gene was transfected into Raji and Jurkat cells by liposome, B7 expression in tumor cells was detected with flow cytometry, and expression of IL-2, IL-4 and IFN-gammamRNA was detected by RT-PCR. Kinetics of secretion of three cytokines was also analyzed at 4, 12, 20 and 48 hours after gene transfection. The results showed that B7(+) Raji cells could induce mRNA expression of IL-2, IL-4 and IFN-gamma on T cell surface; B7(+) Jurkat cells could induce secretion of IL-2 and IFN-gamma. However, B7(-) Raji and B7(-) Jurkat cells could not induce secretion of cytokines. Kinetics of the three cytokines secretion were different, IL-2 and IL-4 were only detectable after 4 hours of T cell activation, whereas IFN-c was detectable after 12 hours of stimulation. The peak levels of IL-2, IL-4 and IFN-gamma were found at 20 hours after activation. It was concluded that tumor cell lines transfected with B7 gene could enhance their immunocompetence, activating T cell efficiently and B7-1 play more critical role in T cell activation and differentiation.

BACKGROUNDCC chemokine receptor 3 (CCR3), expressed on some inflammatory cells, is a member of the chemokine receptor family. Its ligand is eotaxin/CCL11. In this research, we studied the expression and function of CCR3 induced by interleukin-2 (IL-2) and interleukin-4 (IL-4) on human germinal centre (GC) B cells.
METHODSCells isolated from human tonsils were stimulated with IL-2 or/and IL-4 followed by bonding with eotaxin/CCL11. Flow cytometry was used to detect expression of CCR3 on GC B cells and apoptosis of GC B cells. Real time quantitative reverse transcription polymerase chain reaction and Northern blot assays were used to analyse the CCR3 mRNA expressed in the GC B cells. Chemotaxis and adhesion assays were used to determine the effect of eotaxin/CCL11 ligand bonded to CCR3 on GC B cells.
RESULTSThere was no CCR3 expression on human freshly isolated GC B cells. The combination IL-2 and IL-4 could upregulate CCR3 mRNA and protein expression on GC B cells. Eotaxin could not induce GC B cell chemotaxis and adhesion but triggered apoptosis of GC B cells.
CONCLUSIONIL-2 and IL-4 together induced expression of CCR3 on GC B cells, and the receptor acted as a death receptor.
