1.While some researchers search for the roots of obesity in our genes, others investigate infections. Scientists have known for two decades that. surprisingly certain viruses can cause birds or mammals to become Now scientists think they have tracked down a bug that fat. can cause obesity in people.
2. The alleged culprit is human adenovirus-36, or AD-36. A study published 2002 showed that AD-36 injected into monkeys causes dramatic weight gain. In some animals. the injected vius caused body fat to triple. It's unethical to inoculate people with viruses, of course. But in an analysis of u ooo people, the scientists found that those with AD-36 antibodies-a sign that they have been infected-are significantly more likely to be overweight.
3. How could a virus make you fat? When fat cells are exposed to AD-36, they begin to multiply. "We are not saying all obesity is caused by a virus. Genes, metabolism. and habits all play a role," the scientists acknowledge. "But at least one other possibility appears to be infection." 4.As yet, no one knows how widespread AD-36 may be. how big a role it might play in or the current obesity epidemic. If the scientists' suspicions prove correct, the next step would be to develop a vaccine.
