The innate immune response can be life-saving but also life-threatening. Which of the molecular switches in our cells lead to the correct decision? The discovery of CRISPR/Cas9, a bacterial defense system against viral infections, has opened up a myriad of possibilities in functional genetics: In many cases, the targeted deactivation of genes enables conclusions to be drawn about previously unknown functions of individual genes or entire signaling pathways in an immune response1.

CRISPaint, another method based on CRISPR/Cas9, enables transgenes to be introduced into the genome of human cells with high throughput2. By labeling protein-coding genes with GFP and a DNA barcode, followed by sequencing of the barcodes using a new in situ NGS method, it is possible to visualize thousands of proteins in parallel in living cells (live-cell proteomics) 3.

Furthermore, we are also interested in studying the processes for active self-diversification. This is a highly-effective method that our adaptive immune system uses to accommodate the changing threats presented by our environment. Does Nature also have ways of triggering self-diversification in a different context? In order to answer this question, we are developing algorithms to search metagenomic sequencing data for such undiscovered systems and to experimentally characterize them in the lab. This research could lead to future developments in biotechnology, such as antibody generation without the use of lab animals.

Recently, in the context of the SARS-CoV-2 pandemic, we have been developing LAMP-Seq, an NGS-based diagnosis method, which is designed to allow population-wide screenings that only rely on the existing sequencing infrastructure and commercially available reagents4.
