Research group - Qiang Pan-Hammarström
We focus on two main areas of research: Immunogenetics and Cancer Genetics.
Regulation of immunoglobulin class switch recombination in human B cells
The project is aimed at understanding the complex molecular mechanisms involved in DNA editing, repair and recombination during immunoglobulin class switch recombination (CSR) and somatic hypermutation (SHM) and their involvement in the pathophysiological processes leading to immunodeficiency, genome instability and cancer development in humans.
Induced pluripotent stems cells a platform for personalized diagnosis and therapy in patients with primary immunodeficiency
The project is aimed at reprogramming the fibroblasts or peripheral blood B cells derived from IgA deficient (IgAD) patients into pluripotent stem (iPS) cells and to re-differentiate these iPS cells into antibody-producing B cells. If successful, this study may provide a potentially curative treatment in patients with IgA deficiency. They will also provide a methodological platform for studies aimed at replacing cells in patients with a variety of other primary immunodeficiency diseases as well as autoimmune and neurological disorders associated with these diseases.
Discovery of therapeutic targets in B cell lymphoma by next generation sequencing
The project is aimed at identifying potentially treatable molecular targets in mature B cell lymphomas (with focus on diffuse large B cell lymphomas and mantle cell lymphomas) by high-throughput, next generation-sequencing omic- technologies such as whole genome and exome sequencing and RNA-seq.
Our research is supported by the Swedish Research Council (VR), the Swedish Cancer Society (Cancerfonden) and the European Research Council (ERC).
