Abstract

Obesity is connected with numerous diseases, such as type 2 diabetes, atherosclerosis, cancer, and nervous system dysfunctions. Obesity is affected by genetic, environmental, and cultural factors. However, numerous studies indicate that several pathogens might cause obesity. This review discusses recent data and the characteristics of pathogens that are implicated in obesity. In particular, human adenovirus 36 (Ad36) is the most clearly implicated virus in human obesity. It was recently shown that obese groups from the USA, Korea, and Italy have a higher prevalence of serum antibodies against Ad36. The mechanisms of Ad36-induced obesity remain unclear. However, glucose uptake and inflammation are possible mechanisms of Ad36-induced obesity. Overall, this new understanding of causes of obesity has developed into the concept of 'infectobesity' and the possibility of developing a 'vaccine' or 'therapeutic agents' for obesity.
