Dr. Ulvmar did her PhD in skin cancer biology at the Karolinska Institute, Sweden, followed by two postdoctoral periods, first in basic immunology at the University of Birmingham in the UK in the lab of Professor Antal Rot, for which she was awarded a Marie Curie (MC) IEF fellowship and then in vascular biology at Uppsala University in Sweden in the lab of Professor Taija Mäkinen. Among her major research contributions is the identification of a mechanism for chemokine gradient formation in the lymph node (LN), through the expression of the atypical chemokine receptor CCRL1 (ACKR4) on a previously unknown subset of LN lymphatic endothelial cells (Nat. Imm. 2014). Since 2017 she is Associate Professor at Uppsala University in Sweden. The work in her lab aims to contribute to a better understanding of the functions of the LN vasculature and how the vasculature can cooperate with other stromal cells and with the immune cells to regulate the LN immune functions. This knowledge can eventually lead to new strategies to improve and direct the immune responses in e.g. vaccination or in immunotherapy. The lab also addresses how structural and molecular changes of the LN vessels can affect the immune response and tumour metastasis in breast and pancreatic cancer. The experimental strategies include genetic targeting in mouse models, high parameter flow cytometry and single-cell RNA sequencing, but also studies of human clinical and biobank tissue samples using multispectral imaging.
