This only part of the story. There is another type IV hypersensitivity subtype that does not involve T-helper cells (CD4+), MHC-II or professional APCs such as dendritic cells or macrophages. Instead this pathway utilizes MHC-I on tissue cells that have absorbed a hapten and present the antigen directly to CD8+ cytotoxic T-cells. The cytotoxic T cells are activated and release cytokines, performs and granzymes to kill the cell directly. This is sometimes called direct T-cell mediated cytotoxicity.

U said this subtype does not involve t cell so why is it called t cell mediated cytotoxicity?

I think direct t cell mediated cytotoxicity happens after the first exposure of antigen ! 🤔

You gave some wrong information to us, at 2:45-2 :50 u said haptens are bound to antigen and formed a immunogenic particle, but hapters are also antigens but unable to induce immune response, so they are abtigens but not immunogenic. To be immunogenic they bound to carrier protein present in affected tissues and formed conjugate protein, which acts as a immunogenic particle, and engulfed by tissue macrophages or dendritic cell... So foreign particle due to small size they act as hapten.

**There is a correction:** 5:12 pr jo aapne " activated macrophage secretes" btaya hai wo sb activated macrophage nhi TH1 secrete kryega TH1 secretes: IFN gamma, TNF beta, IL-2,3,8. Effects of macrophage activation: Increase class II MHC Molecules Increase TNF receptors Increase oxygen radicals Increase nitric oxide Please correct this part, so tht students Exms m Sahi likh kr aye.

i know that this is an old video. I see a lot of people in the comments with vast knowledge. I believe that I have this condition with a hypersensitivity to some chemical. I have documented exposures to TCE, PCE, benzene, and vinyl chloride. I cannot find anyone with the knowledge or tools to diagnose me. I am in Alabama, but will travel and pay for someone with expertise

Hello sir, so does that mean effector phase is like re-exposure of the same antigen? Thank you.
