    Are you still active? First of all thank you very much for your teaching.
    I do have a really important question to ask you.
    It s the regard the production of IgE, IgG and IgA with the different TCR.
    I hope to hear from you soon.

    Thomas Underhill but for a histopathologist it needs more opsonisation to digest the data.

    This was a very helpful video!! I was hoping to review Ig/BCR as well as this. Where can I find the BCR videos you mention in this video?

    Hi! awesome video, is ITAM apart of the TCR complex? also if so how is its function different than CD3? Thank you!

      thanks for the comment, the CD3s sub-units all have ITAM domains I have a playlist on lymphocyte development if you are interested check it out here: th-cam.com/play/PLC8lVQV4Hx6cngG1q9TXlJHqyjoOR0oB_.html

    I believe at 9:10 you mean zeta chain! I had to look it up too. Other than that, great explanation.

    • @medaphysicsrepository2639
      @medaphysicsrepository2639  9 ปีที่แล้ว

      +Brian Tran Thanks for pointing that one out, you are absolutely correct! its zeta chain, sorry, I actually have a roommate from greece I would always mispronounce the words. let me know if you have any questions (immunology related, I'm horrible with greek)

    how does CD3 direct the TCR to membrane?

    • @medaphysicsrepository2639
      @medaphysicsrepository2639  5 ปีที่แล้ว

      Ehh it kind of depends on the context of the question: Vesicular to membrane transport is still a hot topic of nobel prize winning research and is poorly understood.
      CD3 Knockout leads to the TCR staying in the ER forever and not progressing further, so its definitely critical.
      CD3 and TCR are considered to be "associated" (horrible word choice) with each other before it even arrives at the golgi complex for glycosylation.
      Notice that I have not given you an EXPLANATION, i have merely described how things happen, how the "association" was determined I have no idea (FRET would be my guess). I really absolutely hate the use of the word "association" here too bc it doesnt say anything about the type of molecular connectivity between the two (covalently, non covalently, which one ? idk)
      welcome to immunology: where the most frequently used word in your textbook is "may"
      we can barely describe these events, let alone explain them. let me know if you have any questions and if you have read this entire light novel I wrote you thanks alot

    Are TCRs structurally also similar to MHCs?

    • @medaphysicsrepository2639
      @medaphysicsrepository2639  6 ปีที่แล้ว

      not really, I mean Im willing to bet all PRR's evolved from either the same gene duplication and genome acquisition

      awesome, I assume you are working on immunochemistry ?
      this might help answer your question: th-cam.com/video/CQie-N9MnSw/w-d-xo.html
      I also have the following playlist that might help as well : th-cam.com/play/PLC8lVQV4Hx6fqdOs4mr5TJzmTNp-Csex1.html&spfreload=10

      actually more focus could be done on tcr gene rearrangement for cancerous markers .... and how tcr alpha and beta chain were cloned ..hoe tcr were isolated ..i was looking for that ..btw that videos was good..
