Protein as amorphous evolving matter Prof. Tsvi Tlusty [Info]

Protein as amorphous evolving matter

Protein is matter of dual nature. As a physical object, a protein molecule is a folded chain of amino acids with diverse biochemistry. But it is also a point along an evolutionary trajectory determined by the protein’s function within a hierarchy of interwoven interaction networks of the cell, the organism, and the population. Thus, a theory of proteins needs to unify both aspects, the biophysical and the evolutionary. In this talk, a physical approach to the protein problem will be described, focusing on how cooperative interactions among the amino acids shape the evolution of the protein. This view of protein as evolvable matter will be used to examine basic questions about its fitness landscape and gene-to-function map. Department of Physics, National University in Ulsan, South Korea

From cell circuits to collective cell behaviour Prof. Leah Edelstein-Keshet [Info]

From cell circuits to collective cell behaviour

In order for our body to heal and repair injury, cell sheets must move together to seal a gap. To overcome infection, white blood cells need to track down and destroy pathogens. Such processes can only work if cells can "sense" their environment and "decide" to move in the right direction, or else, to coordinate with neighbouring cells. This requires tight control of adhesion between cells, as well as the speed and direction of cell migration. In this talk, I will describe mathematical and computational research on cell migration, both in normal and abnormal (cancer) cells. I will focus mainly on recent "multi-scale" modeling, where we combine our understanding of the "molecular machinery" inside cells, with information about how cells interact with one another. We use this approach to investigate the behaviour of groups of cells. Combining mathematics and computational methods, we can get some insights on cell organization in development and in wound healing, as well as what could go wrong in disease such as cancer.
