Cellular Signalling in Health and Disease

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

• Describe how the signalling pathways of cytokine receptors are activated and explain the importance of regulation
• Describe how signals are transduced from cell surface receptors to regulate the transcription of nuclear genes
• Describe how intervention in key signalling pathways may be used to treat inflammatory disease of the CNS.
• Outline the importance of apoptosis during embryonic development and in the maintenance of appropriate cell number.
• Identify members and roles of the Myc/Max family of transcriptional regulators
• Explain the fundamental principles that underlie intracellular signalling pathways, and describe how cell surface receptors activate major signalling pathways such as PI 3-kinase/Akt and Ras/ERK
• Outline the role of mTOR, PI 3-kinase and Ras/ERK signalling in diseases such as cancer and cardiac hypertrophy and describe strategies for tackling the defects in cell signalling that give rise to specific diseases
• Explain the similarities and differences between the induction of apoptosis by extrinsic and intrinsic pathways and describe some of the characteristic changes to cellular components during the execution stage of apoptosis
• Explain the biological role of cytokines in health and disease and describe the basic function of the different Toll like receptors and cytokine receptors
• Explain the physiological roles of the mTOR (mammalian target of rapamycin) pathway in cellular regulation and the immune system, and the mechanisms by which mTOR signalling is activated by hormones and growth factors
• Review the possible mechanisms that control the innate and acquired immune responses in the central nervous system
• Distinguish the mechanisms of oncogenic activation of Myc and explain how Myc can function as a transcriptional activator or a transcriptional repressor
• Discuss the implications of a sample of current research in this field for our understanding of cellular signalling.

The module comprises an introduction/revision to inflammatory mediators and a detailed survey of the way that they interact in different diseases. This information is integrated in the context of a number of human diseases affecting a range of different tissues within the body. Strategies that are used to devise new therapeutic approaches to inflammatory disease are discussed within each topic.

The module will comprise of lectures and a final revision lecture (if required), research paper seminars and independent study.

Students will have access to a list of selected literature for further reading around each topic.
