Research group Erik Melén
Our research projects aim to advance the understanding about the complex interplay between genetic and environmental factors involved in lung growth, respiratory and allergic diseases from childhood to adulthood. Our long-term goal is to develop knowledge and treatments for better lung health over a person’s lifetime.
Several of the projects are based on data from the Swedish birth cohort, BAMSE that allows for unique investigation of health and disease in a large number of subjects up to 24 years. In addition, detailed information about perinatal events, environmental exposures such as air pollution and tobacco smoke exposure from birth and onwards has been collected. In our ongoing genetics projects, genome-wide approaches are primarily used (GWAS, global methylation analyses and RNA sequencing / microarray approaches) together with detailed clinical and epidemiological data. As such, we are conducting translational research, from bench to bedside, using clinical and epidemiological data sets. For example our projects focus on the long-term consequence of preterm birth on lung function in young adulthood, identification of subgroups of the population that are particularly vulnerable to air pollution exposures and elucidation of new genetic mechanisms for disease development.
