Dynamic nanolandscape of immune receptors

Cell Biophysics & Physical Biology

Project description

Our aim is to exploit state-of-the-art optical nanoscopy to unravel the nanolandscape of cells of the immune system and get dynamic information of the cell surface organization of cellular receptors and subsequent signalling pathways at the nanometer level. In particularly in the immune system, which defends our body against pathogens, recognition and elimination of nanometer-sized pathogens is regulated through complex cell signaling and cell communication to ensure a swift and effective protective response. Understanding how these cell surface processes are orchestrated at the molecular level on living cells is at the core of this project.

  • Role of disorder in cell membranes and connection with function

    Weak ergodicity breaking of receptor motion in living cells stemming from random diffusivity in PRX. Fundamental biological processes, including the capture of pathogens by membrane receptors, are regulated by molecular transport. A joint collaboration between the ICREA Professors at ICFO Maria Garcia-Parajo and Maciej Lewenstein show that receptor functioning is linked to nonergodic dynamics, which … Continue reading →
