Summary
How blood vessel stiffness regulates their growth and maintenance. This project aims to reveal an unidentified molecular mechanism of how endothelial cells in the walls of blood vessels detect stiffness of the surrounding environment in order to regulate blood vessel growth and maintenance. The results are expected to advance the emerging field of mechanobiology by combining cutting-edge cell biology and microscopy techniques carried out in novel 3D cell culture and unique quail models.

This project aims to reveal an unidentified molecular mechanism of how endothelial cells in the walls of blood vessels detect stiffness of the surrounding environment in order to regulate blood vessel growth and maintenance. The results are expected to advance the emerging field of mechanobiology by combining cutting-edge cell biology and microscopy techniques carried out in novel 3D cell culture and unique quail models. The benefits of these outcomes include generation of knowledge on the impact of tissue stiffness on the signalling mechanisms that drive formation and maintenance of blood vessels. In the long term, this fundamental understanding could give rise to major developments in emerging industries such as organ bioengineering.Read moreRead less

Summary
Biophysical mechanisms regulating early T cell signalling events. T cell activation in response to foreign pathogens or cancer cells requires a complex set of protein interactions which must be controlled in space and time. This project will use new microscopy methods with single-molecule sensitivity to determine how the cell membrane and protein clustering regulate these interactions.

Summary
Mechanotransduction within the Immune Synapse. This project plans to use advanced microscopy to study the forces involved in T-cell activation which lead to an immune response. T-cells readily detect the presence of even a single antigenic peptide-major histocompatibility complex (pMHC) and discriminate among thousands of endogenous pMHC via T-cell receptors (TCRs) on the surface of antigen-presenting cells. The mechanisms underlying this phenomenal sensitivity have remained elusive, but more re ....Mechanotransduction within the Immune Synapse. This project plans to use advanced microscopy to study the forces involved in T-cell activation which lead to an immune response. T-cells readily detect the presence of even a single antigenic peptide-major histocompatibility complex (pMHC) and discriminate among thousands of endogenous pMHC via T-cell receptors (TCRs) on the surface of antigen-presenting cells. The mechanisms underlying this phenomenal sensitivity have remained elusive, but more recent studies suggest mechanical forces to be instrumental. To investigate their role, the project plans to introduce force sensors into the immune synapse. Understanding the molecular mechanisms could provide new approaches to improving adoptive immunotherapy and to generating new hypotheses for drug development and targeting.Read moreRead less

Summary
The influence of crosstalk between protein post-translational modifications on the propagation of molecular signals. The ability of a cell to respond appropriately to its surroundings is a result of interactions between proteins and chemical modifiers termed post-translational modifications (PTM). This project will show how PTM interactions (competition/ cooperation) influence cellular outcomes in response to changes in the environment.
