Qiang Pan Hammarström
I am a professor of clinical immunology at the Department of Biosciences and Nutrition, Karolinska Institutet.
I was trained as a medical doctor and graduated from Sun Yat-Sen Medical University in China in 1993. During 1993 and 1994, I worked as a physician at the Guangzhou Respiratory Disease Research Institute. I obtained my PhD degree in Clinical Immunology / Immunology at the Karolinska Institutet in 1999 and carried out postdoc training at Harvard Medical School in 2000. In 2001 I came back to the Karolinska Institutet where I became an associate professor and group leader in 2004. I was appointed professor of clinical immunology at the Karolinska Institutet in 2011.
I have extensive international experience. I was a guest professor at Beijing University from 2005 to 2009, a visiting scientist in Harvard Medical School in 2012, a visiting professor at Rockefeller University from 2013 to 2015, a visiting scientist in the Broad Institute at Harvard and MIT from 2016 to 2017. Currently I am a visiting professor at Sun Yat-Sen University Cancer Centre and Tianjin Medical University Cancer Institute in China.
I have supervised 10 PhD students and trained 16 postdocs. I have published altogether 114 papers in areas of immunoglobulin gene diversifications, primary immunodeficiencies, genome instability, B cell malignancies 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 funded by the Swedish Research Council (VR), Swedish Cancer Society (Cancerfonden), Swedish Childhood Cancer Foundation (Barncancerfonden), European Research Council (ERC), Stockholm Cancer Society, the Swedish Foundation for International Cooperation in Research and Higher Education (STINT), and Center for innovative Medicine (CIMED).
