The accumulation of critical receptors at the tips of membrane protrusions on the cell surface was recently discovered by our group and others (Franke et al. 2022). Such nanoscopic organisation of receptors is key for regulation of signalling events controlling complex cellular processes. In this project, we will study how stress factors (e.g., temperature or oxidative burst) affect three-dimensional organisation of molecules on the surface of human leukocytes. The effect of metabolic inflammation factors such as leukotrienes and bradykinins, which are lipophilic compounds, will be tested separately and in combination with physical stress factors. This research will help to understand the impact of physical stress and in combination with inflammation on cell morphology and key cellular processes. The work will include imaging of receptors and associated effector molecules on the surface of stressed T cells. The imaging approaches will include a panel of advanced fluorescence and super-resolution microscopy techniques, which will be complemented by flow cytometry and some basic biochemistry methods to determine the impact of stress on T-cell function.
