This research was designed to analyze the possible associations of Arg389 Gly ADRB1 and Trp64 Arg ADRB3polymorphisms in children with obesity.A cross-sectional study included 1,046 school-age Mexican participants（6-12 years old） from the cities of San Luis Potosi and Leon.Children were classified as non-obese or obese according to their body mass index（BMI） percentile;obese children had a BMI≥95th percentile for sex and age.Biochemical data were collected.Polymorphisms were detected using TaqMan qPCR assay.A logistic regression analysis was used to calculate the risk of obesity based on genotypes.Differences were found between groups where obese children had a significant increase in systolic and diastolic blood pressure,fasting plasma glucose,insulin,HOMAIR,LDL-cholesterol,triglycerides,and lower HDL-cholesterol compared with the normal weight group（P 〈 0.05）.The distribution of allele frequency in the population was Arg = 87.4 and Gly = 12.6（Hardy Weinberg equilibrium x^2= 3.16,P = 0.07）;Trp = 81.5 and Arg= 18.5（Hardy Weinberg equilibrium x^2 = 2.2,P = 0.14） for ADRB1 and ADRB3,respectively.Even though no different frequencies of Arg389 Gly polymoiphism between groups were found（P = 0.08）,children carriers of one Gly389,ADRB1 allele had a risk for obesity of OR = 1.40（95%CI,1.03-1.90,P =0.03） after adjustment for age and gender.No other association was found for Trp64 Arg ADRB3 polymorphism.Only the Arg389 Gly ADRB1 polymorphism was associated with risk for obesity in Mexican children.

Role of IL-10 and TGF-β1 in local immunosuppression in HPV-associated cervical neoplasia

Cervical cancer is a worldwide disease that constitutes a significant public health problem, especially in developing countries, not only due to its high incidence but also because the most affected population comprises women who belong to marginalized socio-economic classes. Clinical and molecular research has identified immunological impairment in squamous intraepithelial cervical lesions and cervical cancer patients. Human Papillomavirus(HPV) has several mechanisms for avoiding the immune system: it down-regulates the expression of interferon and upregulates interleukin(IL)-10and transforming growth factor(TGF)-β1 to produce a local immunosuppressive environment, which, along with altered tumor surface antigens, forms an immunosuppressive network that inhibits the antitumor immune response. In this review we analyzed the available data on several deregulated cellular immune functions in patients with NIC Ⅰ, NIC Ⅱ and NIC Ⅲ and cervical cancer. The effects of immunosuppressive cytokines on innate immune response, T-cell activation and cellular factors that promote tumor cell proliferation in cervical cancer patients are summarized. We discuss the functional consequences of HPV E2, E6, and E7 protein interactions with IL-10 and TGF-β1 promoters in the induction of these cytokines and postulate its effect on the cellular immune response in squamous intraepithelial cervical lesions and cervical cancer patients. This review provides a comprehensive picture of the immunological functions of IL-10 and TGF-β1 in response to HPV in humans.
