Contagious obesity: from adenovirus 36 to RB dysfunction
  Significant overweight represents a major health problem in industrialized countries. Besides its known metabolic origins, this condition may also have an infectious cause, as recently postulated. Here, it is surmised that the potentially causative adenovirus 36 contributes to such disorder by inactivating the retinoblastoma tumor suppressor protein (RB) in a manner reminiscent of a mechanism employed by both another pathogenic adenoviral agent and insulin. The present insight additionally suggests novel modes of interfering with obesity-associated pathology.
