    Thank you so much for your lecture videos. They really help with my studying and allow me to stay ahead in my classes. I do have one question, would you happen to have Chapter 9 and 10. Because it says that they have been deleted from your immunology playlist

      They should be there! I redid them this semester and so I deleted the previous versions. Here is Chapter 9 Part 1 to get you going: ua-cam.com/video/3qKdJPPXoI4/v-deo.html

      @@srsletten Thank you so much!! I really enjoy your lessons. I hope you can do biochemistry or Molecular Biology 1? Do you have a list of the classes then you can teach on?

      So far only immunology, but I am tossing around the idea of doing biochemistry.@@rosyace7732

    what is the difference between viruses that are encountered with CD4 and CD8 cells and viruses that are killed only by CD8 cells?

      I don't know if I fully understand your question, but here is some information that might help you out: CD4 T cells do not directly kill infected cells. Instead, they help orchestrate the immune response by secreting cytokines that activate other immune cells, including CD8 T cells, B cells, and macrophages. Once activated, CD8 T cells release perforins and granzymes that induce apoptosis in the infected cells, effectively eliminating the virus. The involvement of CD4 T cells ensures a robust and coordinated immune response, including the production of antibodies and activation of various immune cells; CD8 T cells perform the actual killing of infected cells. Antibodies produced by effector B cells (plasma cells) guided by T cells, will help neutralize virus particles before they an interact with host cells.
