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

Clotting factor XIII-A is a member of the transglutaminase family of enzymes. Transglutaminases introduce covalent cross-links between other proteins, and in the case of FXIII-A, it cross-links the chains of fibrinogen to one another to stabilize blood clots. Transglutaminases are unusual in that, while they can be secreted from cells, they lack the signals required to direct them to the ER-Golgi pathway. Thus, they are among a small group of proteins that undergo unconventional secretion.

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

<p>Recent studies have begun to clarify the pathways by which a few other unconventionally secreted proteins are released from cells, and we intend to apply the approaches that have emerged to understand the secretion of FXIII-A. Our recent studies have suggested that vascular macrophages secrete FXIII-A into the blood-stream and we will concentrate on isolating these cells, and establishing in vitro culture models under which cells adopt the characteristics of vascular macrophages.</p> <p><strong>References:</strong></p> <p>Association of coagulation factor XIII-A with Golgi proteins within monocyte-macrophages: implications for subcellular trafficking and secretion.

<h2 class="heading">How to apply</h2>

<p>Please note these are not standalone projects and applicants must apply to the PhD academy directly.</p> <p>Applications can be made at any time. To apply for this project applicants should complete a<a href="https://medicinehealth.leeds.ac.uk/downloads/download/129/faculty_graduate_school_-_application_form"> Faculty Application Form</a> and send this alongside a full academic CV, degree transcripts (or marks so far if still studying) and degree certificates to the Faculty Graduate School <a href="mailto:fmhpgradmissions@leeds.ac.uk">fmhpgradmissions@leeds.ac.uk</a></p> <p>We also require 2 academic references to support your application. Please ask your referees to send these <a href="https://medicinehealth.leeds.ac.uk/downloads/download/130/faculty_graduate_school_-_scholarship_reference_form">references</a> on your behalf, directly to <a href="mailto:fmhpgradmissions@leeds.ac.uk">fmhpgradmissions@leeds.ac.uk</a></p> <p>If you have already applied for other projects using the Faculty Application Form this academic session you do not need to complete this form again. Instead you should email fmhgrad to inform us you would like to be considered for this project.</p> <p>If English is not your first language, you must provide evidence that you meet the University&#39;s minimum English language requirements (below).</p> <p><em>We welcome applications from all suitably-qualified candidates, but UK black and minority ethnic (BME) researchers are currently under-represented in our Postgraduate Research community, and we would therefore particularly encourage applications from UK BME candidates. All scholarships will be awarded on the basis of merit.</em></p>

<h2 class="heading heading--sm">Entry requirements</h2>

A degree in biological sciences, dentistry, medicine, midwifery, nursing, psychology or a good honours degree in a subject relevant to the research topic. A Masters degree in a relevant subject may also be required in some areas of the Faculty. For entry requirements for all other research degrees we offer, please contact us.

<h2 class="heading heading--sm">English language requirements</h2>

Applicants whose first language is not English must provide evidence that their English language is sufficient to meet the specific demands of their study. The Faculty of Medicine and Health minimum requirements in IELTS and TOEFL tests for PhD, MSc, MPhil, MD are: &acirc;&euro;&cent; British Council IELTS - score of 7.0 overall, with no element less than 6.5 &acirc;&euro;&cent; TOEFL iBT - overall score of 100 with the listening and reading element no less than 22, writing element no less than 23 and the speaking element no less than 24.
