Obesity Vaccine Effective In Mice

New promote weight loss. A new study, published in BioMed Central’s open access journal, Journal of Animal Science and Biotechnology, assesses the effectiveness of two vaccinations, JH17 and JH18, in reducing and increasing weight loss in mice.

Obesity and obesity-related disease is a growing health issue worldwide. Somatostatin, a peptide hormone, inhibits the action of growth hormone (GH) and (IGF-1), both of which increase metabolism and result in weight loss. Vaccination with modified somatostatin causes the body to generate antibodies to somatostatin, effectively removing this inhibition without directly interfering with the and subsequently increasing energy expenditure and weight loss.

Keith Haffer from Braasch Biotech LLC, tested the vaccinations in two groups of ten diet-induced obese male mice compared with a control group of ten mice which received saline injections. Mice in all groups had been fed a high fat diet for eight weeks prior to the study and continued to eat the same food for the duration of the six-week study. The vaccinations were administered twice – at the start of the study followed by a booster vaccination on day 22.

Four days after the first injection of modified somatostatin, the vaccinated mice had a 10% drop in (not seen in the control mice). At the end of the study, results showed that both vaccines induced antibodies to somatostatin and significantly reduced , sustaining a 10% lower , without affecting normal levels of the growth hormone IGF-1, or insulin levels.

“This study demonstrates the possibility of treating obesity with vaccination”, Keith explained. He continued, “Although further studies are necessary to discover the long term implications of these vaccines, treatment of human obesity with vaccination would provide physicians with a drug- and surgical- free option against the weight epidemic.”
