Andrew Hogan

Principal Investigator

Dr Andrew Hogan is a lecturer in Immunology at Maynooth University & Principal Investigator of the Childhood Obesity Immunology Research Group based in the NCRC and Maynooth University. Previously he was a UCD Newman Scholar in Obesity and Diabetes and NCRC Research Fellow. In 2012, Dr Hogan, along with Prof O’Shea & Prof Declan Cody, established the Childhood Obesity Consortium with the support of the NCRC. The goal of the consortium is to investigate the impact of childhood obesity on the immune system, and to investigate the potential of early intervention in halting the progression to co-morbid disease.

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.

Inflammatory markers of antipsychotic weight gain and cardiometabolic dysfunction in youth mental health disorders

Second generation antipsychotics (SGAs) are widely used to manage symptoms of psychosis and irritability in autism spectrum disorder (ASD). Previously considered to have lower side-effects, the safety of SGAs is under review due to associated cardiometabolic dysregulation in some patients. We hypothesize that there is a subgroup of children and adolescents with ASD and early onset psychosis (EOP) who have pro-inflammatory immune profiles prior to starting SGA medication. Secondly, we hypothesise that this subgroup is at increased risk of developing the cardiometabolic
