Build a strong foundation in Immunology with this detailed lecture on the Structure and Functions of the Immune System by Dr. Shambhabi Chakraborty from Tripura Santiniketan Medical College (TSMC). This video provides an in-depth explanation of how our body fights foreign pathogens. We explore the anatomy of lymphoid organs, the maturation of immune cells (B & T Lymphocytes), the complex mechanism of antigen presentation (MHC Class I & II), and the Complement System cascades. 📝 What You Will Learn: Lymphoid Organs: Difference between Primary (Bone Marrow, Thymus) and Secondary (Spleen, Lymph Nodes, MALT) organs. Immune Cells: Maturation and function of B-Cells (Plasma cells) and T-Cells (Helper CD4 vs Cytotoxic CD8). Antigen Presentation: How Macrophages and Dendritic cells present antigens using MHC molecules. MHC Complex: Understanding HLA genes, MHC Class I vs Class II pathways. Cytokines: The role of Interleukins, Interferons, and the concept of "Cytokine Storm." Complement System: Classical, Alternative, and Lectin pathways leading to cell lysis (MAC). ⏱️ Timecodes & Key Topics: Introduction to the Immune System Primary Lymphoid Organs: Bone Marrow & Thymus Secondary Lymphoid Organs: Lymph Nodes & Spleen MALT (Mucosa-Associated Lymphoid Tissue) & Peyer's Patches B-Lymphocytes & T-Lymphocytes: Maturation & Function T-Helper (CD4) vs. T-Cytotoxic (CD8) Cells Macrophages: Phagocytosis & Antigen Presentation Dendritic Cells & Natural Killer (NK) Cells Major Histocompatibility Complex (MHC Class I & II) Cytokines: Functions & Cytokine Storm The Complement System: Classical, Alternative & Lectin Pathways Membrane Attack Complex (MAC) & Cell Lysis 🔗 Connect with TSMC: Subscribe for more medical lectures.
