Cell Signalling: Receptors and Pathways

This lecture covers various aspects of cell signalling, including receptor tyrosine kinases, two-component signalling systems, quorum detection, and the Wnt signalling pathway. It explains how cells communicate through different signalling molecules, such as lipids and second messengers, to regulate gene expression and cellular responses. The lecture also delves into the role of growth factors, G proteins, and protein kinases in signal transduction pathways, highlighting their importance in metabolic integration and immune responses.
