Immunodeficiency Diseases

Primary immunodeficiencies are diseases in which part of the body's immune system is missing or does not function properly. Most primary immunodeficiencies are genetic disorders and the majority are diagnosed in children under the age of one. Translational studies of primary immunodeficiency diseases in patients and gene-targeted experimental models have increased our understanding of the cause for disease and led to development of new therapeutic approaches, including bone marrow transplantation and gene therapy. Understanding primary immunodeficiency diseases has also increased our knowledge of critical mechanisms for correct function of the immune system.OK

Our laboratory has focused on primary immunodeficiency caused by mutations in the Wiskott-Aldrich syndrome protein (WASP). WASP is uniquely expressed in cells of the immune system and coordinates cell surface signaling to changes in the actin cytoskeleton, thereby regulating cell movement, cell-to-cell communication, and intracellular signaling. The clinical outcome of WASP-associated primary immunodeficiency depends on how the mutations affect WASP expression and activity. Mutations that abolish expression of WASP leads to broad dysfunction of the immune system and patients develop eczema, autoimmunity and tumors. Mutations that induce constitutively-active WASP lead to development of severe neutropenia and recurrent bacterial infections. It remains largely unknown how different mutations of WASP can elicit such diverse effects on the immune system. To delineate these strikingly different clinical phenotypes, our laboratory is utilizing patient samples and gene-targeted models. Specifically, we are investigating the role of WASP family proteins, their interacting partners, and the actin cytoskeleton for regulation of allergy, autoimmunity, and cancer. Moreover, we are utilizing our experimental models to test new treatment strategies for primary immunodeficiency diseases.

The overall goal of our research is to increase the understanding of WASP family proteins and their role in immunodeficiency. We expect to reveal critical mechanisms for maintenance of a correctly regulated immune system in health and disease

PhD, Associate Professor Lisa Westerberg
Lisa Westerberg graduated from Stockholm University with a M.Sc. in Molecular Biology and received her Ph.D. in Cell and Molecular Biology in 2003 from Karolinska Institutet where she studied under Professor Eva Severinson. In 2009 she completed her postdoctoral research at Harvard Medical School in the laboratories of Professors Scott Snapper and Luigi Notarangelo. She joined the faculty at Department of Medicine at Karolinska Institutet, Stockholm in 2009 after receiving an Assistant Professor position appointed by the Swedish Research Council. In 2013, Dr Westerberg joined the faculty at Department of Microbiology Tumor and Cell biology as senior researcher and group leader. Dr Westerberg is the treasurer of the Swedish Society for Immunology and coordinates the WASPSTINGS network funded by STINT. Dr Westerberg is a Ragnar Söderberg fellow in Medicine.
