    Aim: We aimed to investigate the adipogenic effects of adenovirus (Ad) serotypes 5, 36 and 8 in a Colo-320 cell line using histochemical, immunohistochemical and electron microscopic methods. Materials & methods: Ad serotypes were inoculated in a Colo-320 cell line and were cultured for 14 days. They were then collected and fixed with 4% paraformaldehyde to analyze their adipogenic effects using histochemistry, immunohistochemistry and electron microscopic methods. Intracellular lipid droplets were detected in the Colo-320 cells inoculated with Ad36 and Ad5 by electron microscopic analyses. Results: After Oil Red O staining, the pink-orange staining was positive intracellularly in Colo-320 cells infected with Ad36 and Ad5. In addition, the leptin immunoreactivity was also positive in these cells. Conclusion: Our results suggested that intracellular lipid accumulation occured after infection with Ad36 and Ad5. The positive staining of Oil Red O and leptin also supported the electron microscopic results; therefore, we conclude that this accumulation occurred due to adipogenic effects of Ad36 and Ad5. © 2013 Future Medicine Ltd.

    Are human adenovirus-5 and 36 associated with obesity in children?
    (BMJ Publishing Group, 2014) Cakmakliogullari E.K.; Sanlidag T.; Ersoy B.; Akcali S.; Var A.; Cicek C.
    Objectives: The aims of this study were to determine the association between adenovirus-5- and adenovirus-36-specific antibodies and obesity in children and to investigate their relationship with serum lipid and leptin levels. Methods: A cross-sectional study was performed on a total of 120 children who were divided into subgroups according to body mass index percentile as obese (Q95th percentile) or nonobese (G95th percentile). The presence of adenovirus-36 and adenovirus-5-neutralizing antibodies was investigated by using the serum neutralization assay. Serum leptin levels were determined by microenzyme immonoassay; highdensity lipoprotein, low-density lipoprotein, triglyceride, and cholesterol levels were measured by chemiluminescence method. Results: The presence of adenovirus-5-specific antibodies was 28.3% and 6.6% in the obese children and in non-obese children, respectively (P = 0.02). The frequency of adenovirus-36-specific antibodies was significantly greater (P = 0.018) in the obese children (26.6%) than in the non-obese children (10.0%). Serum leptin level of the obese group were significantly higher than that of the non-obese group (P = 0.000). Conclusions: Our data support the association between obesity and the presence of specific antibodies to adenovirus-36 and adenovirus-5 in children. Our research has the feature of being the first national study to indicate the relationship between adenovirus-36 and human obesity as well as the first international study to indicate the relationship between adenovirus-5 and human obesity.
