    Errata: perforin is the substance that creates the hole, Granzyne B is the substance that activates Caspase

    • @Bolajilearnings
      @Bolajilearnings 5 років тому +5

      perforin creates holes for the granzyme to enter

      I was goig to say that... perforin perforates... Granzymes, then enter the cell and go activate BAX... and so on

    Bcl stands for "B cell lymphoma"
    (just another way to remember that bcl = anti-apoptotic)

    Not only do you explain it summed up in a simple way, but also you make it easier to remember!
    You've earned that like.

    BAC or BAX has an "A" in it (duh,) which can stand for "Apoptosis" --> these cause apoptosis in the intrinsic pathway

    Mate, thank you so much for your work!
    I'm studying pharmacy and many of your videos are extremely helpful for my revision. Especially the ones focusing on pharmacology, so I'd definitely appreciate more of those. The mnemonics you use are amazing and helped me loads. So glad I found your channel.
    Keep up the good work :)

    What about the specific caspases that are involved in the processes? For example, caspase 2, 8, 9 , 10 being initiator caspases
    But also caspase 9 being a key player in intrinsic apoptosis. On that note, it it important that we know the function of Apaf-1?

    Perforin forms pores on the cell membrane and then granzyme enters through the pores.

    Its actually the perforins that make the pores while the Granzyme enters the cell cytoplasm to activate the caspas

  • @bslaozora
    @bslaozora 3 роки тому +1

    Not a US student and I have some genuine questions...No offense@@
    Is that really enough for getting all the USMLE? I mean like, no need to know exactly which caspase (9, 8, 3...) and how 7 pairs of cytochrome C and APAF1 forming apoptosome, which cleaves procaspase 9 into its active form blablabla...(And other details I don't rmb/I didn't learn)
    Or these stuff are examined within the medical school so not on the USMLE?

    Just a pet peeve, but it's not a-pop-tosis. It's a-puh-tosis. The authors of the original paper that described and named apoptosis included a footnote for proper pronunciation, as it's from Greek. We don't say 'puh-neumonia' or 'puh-tosis.'
    But your videos are amazing. I'm currently using them to study for step 1, and I've gotten so many questions right on my qbank sessions because of these videos, I'm definitely going to join and support.
