2018 Associate professor Anna Forsby

Associate professor Anna Forsby working at the Department of Biochemistry and Biophysics, Stockholm University, Stockholm, and at the Swedish Toxicological Sciences Research Center (SWETOX), Karolinska Institutet, Sweden, is the recipient of the Björn Ekwall Memorial Award for the year 2018 in recognition of her scientific achievements in the field of cellular neurotoxicology and development of non-animal test methods.

Anna Forsby´s main research interest is to study mechanisms for chemically induced acute and sub-chronic neurotoxicity by using different neuronal cell models. The usefulness of the cell models for risk assessment is evaluated by integrating in vitro data derived from the cell models with historic in vivo data from rat and clinical observations from exposed human in predictions models. Furthermore, mechanisms for chemically induced nociception are studied in a recombinant neuronal cell model expressing the Transient Receptor Potential Vanilloid (TRPV) ion channels. The latter research has resulted in the development and evaluation of a cell culture model that holds promise to replace the Draize eye irritation test that is criticized for its animal cruelty.

She has been head of the Department of Toxicology, Dermato-cosmetology and Pharmacognosy in the Faculty of Medicine and Pharmacy at VUB since 2000 and professor since 2001. Her team has developed in vitro models for pharmaco-toxicological purposes as alternatives to the use of experimental animals in biotransformation and toxicity studies of drugs, cosmetics and other chemical substances. The recent focus has been on epigenetic modification of primary hepatocytes to stabilize their specific phenotype in culture, as well as on production of human hepatocytes from mesenchymal progenitor cells of adult human tissues. Prof. Rogiers has more than 310 publications in international peer-reviewed journals and is editor of several scientific books. The research on liver-based in vitro modelling and stem cell technology has led to the acceptance of three patents at VUB. She is a frequently invited speaker at international scientific congresses and has organized several congresses by herself.

At European level, she has been co-chair of SCCS (Scientific Committee on Consumer Safety) and ESAC (ECVAM Scientific Advisory Committee) till April 2013, and continues to be an invited expert. She was a Founding member and the first President (2000-2009) of ECOPA (European Consensus Platform on 3R-Alternatives), bringing together Academia, Industry, Animal welfare and Governmental Institutes in EU countries. Prof. Rogiers is member of several scientific societies and editorial boards of scientific journals. She is European Registered Toxicologist (ERT) since 2010, and coordinator and research partner in several research consortia granted by EU framework programs.

Prof. Rogiers has received several scientific grants, e.g. Doerenkamp-Zbinden Award in 2000.

Professor Vera Rogiers from Vrije Universiteit Brussel (VUB), Belgium, received the Björn Ekwall Memorial Award for the year 2016 at the conference of the European Society For Toxicology In Vitro (ESTIV), held in Juan-les-Pins on 17-20 October 2016. The award ceremony was conducted by Anna Forsby, who delivered the Björn Ekwall Memorial Award 2016 on behalf of the BEMF's board.

The theme of the ESTIV conference in 2016 was In Vitro Toxicology for Safety Assessment with focus on how new technologies can strengthen the interpretation and application of in vitro methods in toxicological research and risk assessment (www.estiv2016.com). Vera Rogiers gave an excellent lecture in the spirit of Björn Ekwall’s concept of basal cytotoxicity. She referred to the Multicentre Evaluation of In vitro Cytotoxicity (MEIC) project, which was the first study that showed that human cells predict human toxicity better than cells from any other species and even mice and rats. Convinced about the fact that human cells are the only relevant tissue for human safety assessment, Rogiers has developed and used human cell and tissue models throughout decades. Lately, Rogiers’ research team have used human postnatal mesenchymal stem cells that are isolated from human skin and differentiated them into functional liver cells. These skin-derived, differentiated hepatic progenitor cells have been shown to be useful for estimation of toxicological responses such as liver damage, liver necrosis and steatosis by using a toxicogenomic approach. Again, Vera Rogiers and her research team present a novel, innovative human cell model that can be used for human safety assessment.
