Barrier Surfaces of the Innate Immune System

Explore the barrier surfaces of the innate immune system in this informative 16-minute video. Delve into the first line of defense against infections, including the skin, respiratory tract, and digestive tract linings. Learn how these cells constantly prevent infection from the environment and discover the role of the microbiome in different areas of the body. Examine features like tight junctions, lysozyme, secretory phospholipase A, and antimicrobial peptides. Investigate the skin microbiome, respiratory tract defenses including the mucociliary escalator and nasal microbiota, and the digestive system's protective mechanisms. Gain insights into the Gut-Associated Lymphoid Tissue (GALT) and the female reproductive tract's defenses. Enhance your understanding of immunology through this comprehensive overview of the body's initial protective barriers.
