Lennart Hammarstrom
I started medical school (Karolinska Institutet) in 1969 and begun doing research (on a part time basis) with Erna and Göran Möller in 1971. After finishing medical school, I went into research full time and presented my PhD thesis (on cell stimulation with mitogens) in 1979. I subsequently completed my practical medical training (AT) and started specializing in clinical immunology, becoming a specialist in 1984. Ever since, I have been mixing clinical work with clinically oriented research.
Initially, I took on the post as a head of the clinical immunology laboratory (in 1997) but later devoted my time more to research and was appointed head of the division of Clinical Immunlogy in 1999, the same year that I became professor (and subsequently Distinguished professor, 2009) at the Karolinska Institutet. I still serve in this position, now having incorporated the transfusion service into our division.

Research description
My main research interests focus around immunogenetics and immunotherapy where I have published more than 500 papers to date. In the former area, we are mainly working on trying to understand the molecular basis of a variety of primary immunodeficiency diseases, including IgA deficiency (the most common form of primary immunodeficiency in Sweden) and common variable immunodeficiency. In the latter area, we are trying to develop novel forms of passive immunity that we can use to treat our patients, utilizing antibodies from different sources. Lately, we have turned to using genetically modified lactic acid bacteria as factories for producing antibody fragments in vivo and although most work has been performed in animal models, we are now preparing for clinical trials.
