    At 01:16 the virally infected dendritic cell presented the viral antigen attached to MHC I to naive CD8 + Tc to turn it into effector Tc .
    Did the dendritic cell present the viral antigen attached to MHC II to the naive CD4 + TH to turn it into TH1 ?

      @@meenasharma9609 I can come up with an answer myself , but I wanted it to be clearly mentioned & thoroughly explained in that illustrated tutorial .
      I'd speculate that activation of CD4 TH0 to CD4 TH1 would produce memory TH1 cells roaming in the circulation ; eventually leading to rapid & potent immune response in any next encounter with viral antigens presented on the surface of virally infected cells along with dendritic cells & excessive flux / activation of naive CD8 Tc cells .
      But another reasonable speculation is activation of CD4 TH0 to CD4 TH2 ; initiating a HUMORAL immune response which is - no doubt - an integral component of the antiviral immune response ; along with the cell mediated Tc response . Thus producing neutralizing antiviral antibodies , memory B cells & memory TH2 cells
      We unanimously agree that developing antiviral antibodies either due to infections or vaccinations is a well known fact monitored by antiviral SEROCONVERSIONS , but little was mentioned about that in the tutorial .

    How come Intra-cellular antigen is presented to both, MHC 1 & MHC 2 ?

    • @iliatcymbal
      @iliatcymbal 4 ปีที่แล้ว +3

      Well, MHC 2 is expressed on antigen presenting cells (eg macrophage or dendrite cells). If macrophage engulfs some microbe or own infected cell, it destroys it with ferments in lysosome and transports some pieces to the MHC 2. Dendrite cells are able to present both of MHC - for T-helpers (MHC 2) and T-killers (MHC 1).

    a little confusion . as you said intracellular viral infection that means the pathogen is inside the cell then how will dendritic cell get it and present it to other immune cell ?
    the virus also infect dendritic cells or the dendritic cells pick up the products of cells destroyed by virus .
    in short i feel like some detail is missing here . plz reply

    First of all: Amazing content on FL !! Secondly, for my understanding: Tc need a second signal in order to kill a target cell right? E.g. the B7/CD28 signal. Is that correct?
