Cell Adhesion

BIOL31771 Cell Adhesion 10 Semester 1 Undergraduate Level 3 Patrick Caswell Unit coordinator School of Biological Sciences 1 FHEQ level (Framework for Higher Education Qualifications) ' Last part of a Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 Cell adhesion is critical for all aspects of cell functioning in multicellular organisms. It is essential for building patterned tissues, maintaining their architecture and regulating their differentiation and behaviour. Many of the major diseases affecting mankind progress through disrupted cellular adhesion. This unit will explore established concepts and the latest advances in controlling basic cellular functions, examine what happens when adhesion systems become defective, and will assess the molecular details of how different classes of adhesion receptors work.

Cell adhesion is critical for all aspects of cell function in multicellular organisms. Cell interactions with the extracellular matrix and with each other are required for building patterned tissues, maintaining their architecture, and regulating their differentiation and behaviour. Alterations in normal adhesion mechanisms are also central in the progression of many of the major diseases affecting mankind. The aim of this unit is to consider the molecular details of how different classes of adhesion receptors work, to explore established concepts and the latest advances of how they control basic cellular functions, and to examine what happens when adhesion systems become defective. A detailed understanding of the central role of cell adhesion in animal biology; the molecular biology of cell adhesion systems; how adhesion links to cell migration, proliferation, apoptosis, differentiation, and to development; how these controls break down in human diseases. An introduction to the concepts of adhesion and its importance in biology will be followed by specialist topics, each covering the relevant areas of cell-matrix and cell-cell adhesion, signalling, development, animal models and human diseases, delivered using a range of lectures, podcasts and workshop based discussions; 4 class presentations on self-directed learning. The topics covered will include:•       Adhesion and a multicellular existence.•       Structural dynamics of adhesion systems.•       Principles of adhesion signalling.•       Cell migration guidance.•       Cell polarity and tissue morphogenesis.•       Sensing and responding to biomechanical forces.•       Coordination of multicellularity and morphogenesis.•       Cell adhesion in organ function. 1 Written exam 70% 2 Written assignment (inc essay) 30% Written examination 1 hour 45 min written examination (70%), consisting of one essays (1 out of 5 questions). Set exercise: Students will receive a research paper forming the basis for self-directed learning and a 1,500 word essay (self-directed learning, 30%).     a) Written feedback on essay; b) feedback on exam scripts after the January exams.  BIOL21121 The Dynamic Cell Pre-Requisite Recommended N Compulsory            Alberts B. et al (2015) Molecular Biology of the Cell (6th edition).
