RhoA signaling: the nanoscale mechanisms of mechanochemical regulation. This project aims to elucidate a new paradigm for regulating cell signals at the nanoscale level. Cell signalling involves the coordination of multi-molecular networks at the plasma membrane, the interface between the cell and its external environment. These are often thought to involve the assembly of multimolecular complexes through the action of protein scaffolds. This project will focus on how the contractile regulator, ....RhoA signaling: the nanoscale mechanisms of mechanochemical regulation. This project aims to elucidate a new paradigm for regulating cell signals at the nanoscale level. Cell signalling involves the coordination of multi-molecular networks at the plasma membrane, the interface between the cell and its external environment. These are often thought to involve the assembly of multimolecular complexes through the action of protein scaffolds. This project will focus on how the contractile regulator, anillin, controls RhoA signalling by kinetic regulation. In particular, how nanoscale clustering of anillin by the dynamic actomyosin cytoskeleton modulates RhoA signalling for contractility and tissue homeostasis. The outcomes of this project are first and foremost fundamental understanding of how cells communicate with one another.Read moreRead less
Defining mechanisms behind the formation of hierarchical vascular networks. Blood vessels form complex branched networks composed of arteries, capillaries and veins. The development and maintenance of different vessel systems (arteries and veins) is dependent on cell adherence properties within each vessel, yet how these are established and maintained remains unknown. This project aims to analyse the differences in junctional dynamics between sprouting arteries and veins, and to identify arteria ....Defining mechanisms behind the formation of hierarchical vascular networks. Blood vessels form complex branched networks composed of arteries, capillaries and veins. The development and maintenance of different vessel systems (arteries and veins) is dependent on cell adherence properties within each vessel, yet how these are established and maintained remains unknown. This project aims to analyse the differences in junctional dynamics between sprouting arteries and veins, and to identify arterial and venous signalling networks that make and maintain vessel identity. This project will reveal how adhesiveness is regulated in order to make a hierarchical, functional vascular network, with implications for engineering of functional, vascularised organs in the biotech sector.Read moreRead less
