Lecture 8a: Comprehensive Immune Response to Infection
UCSD Extension School: Applied Immunology (BIOL-40371)
Summer Quarter 2021
This lecture summarizes the coordination of a comprehensive immune response to a hypothetical bacterial infection in the skin, focusing on the integration of innate and adaptive cell types needed to accomplish the generalized goals of a successful immune response. This overview includes a focus on chemokine gradients and the essential role that they play in the spatial organization of immunity, as well as the immunosuppressive cells and pathways that resolve inflammation to restore tissue homeostasis following the clearance of infection.

    I have been looking for a video explanation of the T Cell activation processes as clear as this for the last 7 years. My son was born with ORAI1 deficiency and passed away in 2017. I knew what went wrong and could explain to someone who had no idea, but i wanted to know exactly where in the activation process it went wrong. Thank you. Amazing that through all the genetic coding that goes in to one human being, all it takes is the substitution of 1 letter twice in one gene to catastrophically collapse it all. . .

As a learner, I have found them to be incredibly fundamental to my understanding and appreciation of immunology. Your ability to simplify complex concepts and engagingly present them has made a significant difference in my learning journey. The depth and breadth of your knowledge, as well as your passion for the subject, shine through in each video. Your work has not only enriched my knowledge but also sparked a deeper interest in immunology. It is individuals like you who make learning accessible and enjoyable for many of us, and for that, I am truly grateful. Please continue to share your expertise and passion with the world. Your contributions are making a difference in ways you may not even realize. Thank you once again for your invaluable work.

If you have a mouse model with a floxed gene and a Cre under the K18 promoter... what is the proper control mouse to use? Is it a wildtype mouse? Or a heterozygote mouse that has the Cre under the K18 promoter and an empty LxP cassette? Not sure... please help..

      The TCR subunits-alpha, beta, gamma, and delta-pair to form two distinct types of TCRs: alpha-beta (αβ) and gamma-delta (γδ). The alpha (α) and beta (β) chains pair to form the αβ TCR, which is the most common type and primarily recognizes peptide antigens presented by MHC molecules. The gamma (γ) and delta (δ) chains pair to form the γδ TCR, which recognizes a broader range of antigens, including non-peptide antigens, and is less dependent on MHC. αβ T cells are mainly involved in adaptive immune responses, while γδ T cells often play a role in innate immunity and tissue surveillance.

    • @azca.
      @azca. 11 дней назад

      "CD3s+ with CD8+ and anti-TCR gamma-delta+" indicates a T cell that expresses the CD3 complex, which is present on all T cells, along with the CD8 co-receptor, typically found on cytotoxic T cells. The "anti-TCR gamma-delta+" part means this T cell expresses the gamma-delta (γδ) T-cell receptor, which is less common and is involved in recognizing a broader range of antigens. "CD3s+, CD4-, CD8-, and anti-TCR gamma-delta-" describes a T cell that also expresses the CD3 complex but lacks both CD4 and CD8 co-receptors, making it a double-negative T cell. The "anti-TCR gamma-delta-" part means this T cell does not have the gamma-delta TCR, indicating it likely expresses the more common alpha-beta (αβ) TCR instead.

    why is there only one CDR primarly involved in antigen binding for TCRs whereas the CDRs in Antibodies are all equally equivalent in regards to antigen binding?

    • @azca.
      @azca. 11 дней назад

      In TCRs, CDR 3 is primarily involved in antigen binding because it directly interacts with the peptide presented by the MHC molecule, which is the main focus of TCR recognition. CDR1 and CDR2 regions mainly contact the MHC itself, rather than the peptide. In contrast, antibodies bind directly to free antigens, allowing all six CDRs (three from each of the heavy and light chains) to equally contribute to diverse antigen interactions.

    Will be interesting to see if TCR can detect difference in epitopes at subatomic levels like replacing the H with deuterium or changing the stereochemistry of amino acids. GPCR for olfaction in drosophila can do that. If TCR can do it, this opens up a new field of research for autoimmunity. Damn I need funding for this project.! Btw should have included kinetic segregation model.

    • @shrijitanath
      @shrijitanath Год назад

      That is an interesting thought but not likely to happen, since the criteria of the two receptors to interact with their respective ligands are quite different. Also, one must consider the huge difference in the size and nature of the ligands that these two receptors detect. And changing the epitopes on such subatomic levels may at best influence the TCR's affinity for the epitope itself but even that would require the change to be significant enough.
