The Quirin Hammer team is part of the Hans-Gustaf Ljunggren group at the Center for Infectious Medicine (CIM).
About our research
The team explores signals that regulate the activation of immune cells with a focus on cytotoxic effector cells of the innate immune system. Innate immune cells with cytolytic properties such as natural killer (NK) cells represent the first line of defense against virus infections and developing cancers. NK cells respond to a broad range of viruses and tumor cells using partly overlapping and partly very distinct pathways.
Central aspects of our research are to delineate the molecular signals that allow NK cells to recognize virus-infected cells and to study by which means NK cells discriminate between healthy and tumor-transformed cells. For this, we employ a broad range of in silico, cellular, as well as molecular biology techniques and study samples from patients with ongoing disease. In parallel to understanding the signals that initiate and restrict NK cell activation, we aim at exploiting such recognition pathways for cell therapy against cancer.
