Investigating the impact of childhood obesity on innate immune cell function and metabolism, and their modulation by Metformin and Glucagon like peptide-1

Currently there is no protocol for the targeting inflammation in childhood obesity, allowing the development of co-morbid diseases to go unchecked into adulthood. We aim to investigate the impact of the anti-diabetic agent metformin (in vivo) and the weight loss and immunomodulatory agent Glucagon Like Peptide-1 (in vitro) on obesity driven inflammation in children. This will generate an expanded evidence base for potential therapeutic use in childhood obesity.
