Group Leader at Max Planck Institute for Biology of Ageing interested in mitochondria, microbes and metabolism
Dr. Lena Pernas is MPI for Biology of Aging. The overarching goal of the Pernas lab is to discover interesting biology and understand how human metabolism influences the progression of infectious disease at the cellular and organismal level. The prevailing perception is that the host cell is an exploitable ‘growth media’ for microbes. However, a logical consequence of microbial manipulation of host metabolism is the emergence of host metabolic counterstrategies to limit exploitation by microbes and restrict their growth. The research focus of our lab is the study of how metabolism is rewired to execute cellular defense against microbes. A key interest of our studies therefore is elucidating the inputs that rewire metabolism during infection. Aging has profound effects on metabolism and the response to microbial infection and therefore provides an optimal angle to begin dissecting these inputs. We use the genetically tractable human parasite Toxoplasma gondii as a model pathogen and combine advanced live cell imaging, protein and metabolite profiling, and genetic screens, with molecular and biochemical approaches.
