<h2 class="heading hide-accessible">Summary</h2>

One full scholarship is available at the Leeds Institute of Cardiovascular and Metabolic Medicine. This scholarship is open to UK applicants and covers fees plus maintenance. This fully funded PhD place provides an exciting opportunity to pursue postgraduate research in the field of mechanosensitive ion channels.

<h2 class="heading hide-accessible">Full description</h2>

<p>The ability of many organisms to sense mechanical forces generated e.g., by the heart is of vital importance for many of their functions e.g., control of blood pressure and respiration. For this reason, proteins that sense mechanical forces have an important role in human health. This project asks the fundamental question; how force is sensed by proteins found in the cell membrane. Despite some recent advances, it is still unknown how such proteins functions in diverse cellular environments and how they sense mechanical force.</p> <p>We recently showed that changes in the cytosolic region of a very important ion channel, the PIEZO1 ion channel is critical for its activation. In this project, we will use computational methodologies integrated with lab-bases studies to develop in-depth and molecular understanding of how PIEZO1 channel acts on mechanical force. In particular, the student will use molecular dynamics simulations to determine the conformational changes required within PIEZO1 channel for activation and how specific lipids regulate its activation. The models derived from the computer simulations will be evaluated/refined experimentally, using electrophysiology.</p> <p>The outcome of this study will reveal the activation mechanism of PIEZO1 in unparalleled molecular detail and it will show how the composition of the cell membrane has a regulatory effect in PIEZO1 function. Mutations on PIEZO1 have been shown to result in lymphatic dysplasia in humans, anemias, and potentially other abnormal conditions including heart failure. Therefore, understanding the function of PIEZO1 channel in molecular detail is critical as it can inform structure-based drug discovery for Piezo-related diseases.</p> <p>This position would suit a student with a biology, biochemistry, chemistry or physics background, or a combination of these. The student will be a part of a multidisciplinary team that already studies Piezo channels and has extensive experience on using advanced computational and lab-based approaches to study these channels.</p>
