I cannot thank you enough for these lectures. I have now finished this whole series of the Immunology lectures and I have never understood something ever so clearly from watching a video in one go without rewinding the video. You're amazing and I hope you can understand how much you're helping students around the world. There's nothing missing from your videos, they're just perfect. I'm definitely donating once I get my pay. Greetings from Sweden and once again, thank you!

brilliant! But one question, can NK-cells also recognize an infected cell and it's foreign antigen on MHC class 1? or only the cells without MHC?

[@vanessal.6891]

NK is a bad ass!

[@st0nedg0at]

Another great lecture! Question: How do NK cells know not to kill red blood cells?

[@gggggggggg-uc3ss]

They don't, because red cells not have antigen epitopes in there cell membrane

[@Chrysolite-kn3mz]

(ncbi) the RBCs doesn't present ligands on their surface for NK cells to bind, thus they're being prevented from getting attacked by NK cells (healthy person)

Just found out your Chanel through another KZbinr. Hey, you're insanely brilliant! Thanks many. Please anyone help me know how would I help him make more money for him to make more vedios for us. Thanks

[@caidenedwards7370]

I was wondering why cancer can go undetected even with nk cells because then how would cancer be a problem if nk could bind to any abnormal cell

[@rawanisameldin.2003]

In this case the rate of the growth of the cancer cells beats the ability of the immune system to cope with this change, because we know that cancer cells are very hyperactive, so there will always be new cancer cells that replicate rapidly to give birth to other ones. This is just a guess though, hopefully the teacher sees this question and answers it.

Tumor cells have some mechanisms via which they evade the immune surveillance. Example is thriving on/hijacking the immune checkpoints, also the activities going on in the tumor microenvironment are contributory factors to how they can evade the immune system. I hope this helps a lil. You might be interested in reading journals on tumor immune evasion or immunosurveillance.
