Chapter 6: Cell Communication and Signal Pathways

Delve into the essential processes of cell-to-cell communication and signal transduction in this comprehensive Chapter 6 lecture! Designed for students, educators, and healthcare professionals, this video explores: Cell-to-Cell Communication: Local communication (gap junctions, autocrine and paracrine signaling) and long-distance communication via hormones and neurotransmitters Signal Pathways: How chemical signals (ligands) bind to receptors and activate intracellular responses Receptor Types: G protein-coupled receptors, receptor-enzymes, ion channels, and integrin receptors Signal Transduction Mechanisms: First and second messengers, signal amplification, and cascades Calcium and Novel Signal Molecules: The role of calcium as an intracellular messenger and other novel molecules (e.g., nitric oxide) Receptor Modulation: Agonists, antagonists, and how drugs affect receptor activity (e.g., beta blockers) Homeostatic Reflex Pathways: Neural and endocrine responses for maintaining balance, including feedback loops Master the mechanisms behind cellular communication and their role in maintaining homeostasis with detailed explanations, diagrams, and real-world examples.
