- LifeTime aims to track, understand and target human cells during the onset and progression of complex diseases and their response to therapy at single-cell resolution. This mission will be implemented through the development and integration of single-cell multi-omics and imaging, artificial intelligence and patient-derived experimental disease models during progression from health to disease. Analysis of such large molecular and clinical datasets will discover molecular mechanisms, create predictive computational models of disease progression, and reveal new drug targets and therapies. Timely detection and interception of disease embedded in an ethical and patient-centered vision will be achieved through interactions across academia, hospitals, patient-associations, health data management systems and industry. Applying this strategy to key medical challenges in cancer, neurological, infectious, chronic inflammatory and cardiovascular diseases at the single-cell level will usher in cell-based interceptive medicine in Europe over the next decade.

- Metabolomics examines the small molecules involved in cellular metabolism. Approximately 50% of total phenotypic differences in metabolite levels is due to genetic variance, but heritability estimates differ across metabolite classes. We perform a review of all genome-wide association and (exome-) sequencing studies published between November 2008 and October 2018, and identify >800 class-specific metabolite loci associated with metabolite levels. In a twin-family cohort (N = 5117), these metabolite loci are leveraged to simultaneously estimate total heritability (h2total), and the proportion of heritability captured by known metabolite loci (h2Metabolite-hits) for 309 lipids and 52 organic acids. Our study reveals significant differences in h2Metabolite-hits among different classes of lipids and organic acids. Furthermore, phosphatidylcholines with a high degree of unsaturation have higher h2Metabolite-hits estimates than phosphatidylcholines with low degrees of unsaturation. This study highlights the importance of common genetic variants for metabolite levels, and elucidates the genetic architecture of metabolite classes.

- The anti-tuberculosis vaccine Bacillus Calmette-Guerin (BCG) is able to boost innate immune responses through a process called trained immunity. It is hypothesized that BCG-induced trained immunity contributes to protection against Mycobacterium tuberculosis infection. Since alveolar macrophages are the first cell type to encounter M. tuberculosis upon infection, we aimed to investigate the immunomodulatory effects of BCG vaccination on alveolar macrophages. Searching for a less-invasive method than bronchoalveolar lavage, we optimized the isolation of alveolar macrophages from induced sputum of healthy volunteers. Viable alveolar macrophages could be successfully isolated from induced sputum and showed signs of activation already upon retrieval. Further flow cytometric analyses revealed that at baseline, higher expression levels of activation markers were observed on the alveolar macrophages of smokers compared to non-smokers. In addition, BCG vaccination resulted in decreased expression of the activation markers CD11b and HLA-DR on alveolar macrophages. Future studies should evaluate the functional consequences of this reduced activation of alveolar macrophages after BCG vaccination.
