Ongoing projects - Examples
The effect of temperature on the bumblebee brain
Department of Zoology, Stockholm University
The aim of the project is to understand if and how the information carried by neurons in the bumblebee brain is affected by temperature. The findings will have consequences for understanding how increasing environmental temperatures, such as those that are occurring as a result of climate change, will affect the function of insect nervous systems and behavior.
Evaluation of autofluorescence life-time imaging to observe differences in biological samples
Department of Ecology, Environment and Plant Sciences, Stockholm University
Imaging Candida albicans infection in the mouse kidney
Department of Molecular Biosciences, Stockholm University
C. albicans cells constitutively expressing mCherry (red) were stained with FITC and analysed in a systemic murine model of infection and visualized colonizing a kidney. Green, FITC associated with mother cells (yeast form); Red, mCherry expression in growing daughter cells; note hyphal morphology; Teal, NAD(P)H autofluorescence. (Unpublished data, M. Ward, F.G.S. Silao, C. Peuckert and P.O. Ljungdahl).
Visualization of Toxoplasma dissemination and immune cell migration in mice
Department of Molecular Biosciences, Stockholm University
