Adenovirus 36 y su potencial contribución en el desarrollo de obesidad.

Francisca Villavicencio, Macarena Valladares


The evidence of the last 20 years shows a link between viral infections and obesity in animals and humans. There are five adenovirus which have been associated in development of obesity in animals. SMAM-1 virus was the first studied in humans associated with obesity. There is compelling evidence that Ad-36 virus could contribute to the development of obesity in humans and it is related with body mass index (BMI). This manuscript reviews the association between Ad-36 and the other four adenovirus infections with obesity. An electronic search of articles in the databases PubMed and Scielo, with use of key words: obesity, infection, adipose tissue, Ad-36, 3T3- L1 was performed. The search was restricted "human" and "animals". The importance of the relationship between virus infections and obesity has increased over the past two decades. Ad-36 shows more compelling evidence in humans. There are reports involving this virus in the enhancement of adipogenesis, adipocyte differentiation, a lower secretion of leptin and an increased insulin sensitivity. Future work should focus in larger cohort studies to confirm this association, which explains the global obesity epidemic from a new perspective.
