The Immune System Explained I – Bacteria Infection

36
2



Every second of your life you are under attack. Bacteria, viruses, spores and more living stuff wants to enter your body and use its resources for itself. The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome. An animation of the immune system.

  2. Immuno-oncologist here: Overall great video, and I deeply appreciate that you took the time to specify what extra complexity you wouldn't be covering. I think your approach is fantastic for people completely new to biochemistry or immunology.
    I was only somewhat disappointed (in a completely unsurprised, 'I would have done the same' way) that you didn't go into the "training" of T-cells. One of my favorite immunological mechanisms that we're still learning a lot about is the germinal center. The training processes that happen here are not entirely understood, and are extremely complex, specific, and also are a great example of rapid micro-evolution. If you'd like to make a video on that, well, good luck!
    Finally, as a general rule, I like to see a sample of some unanswered questions or mysteries presented as well, as this helps stimulate the brains of beginners. For example, I think there were a couple opportunities in this video to briefly mention current challenges or the incompleteness of our understanding. You already took the few seconds to explain what you wouldn't be going into, and I see this as an extension of that. The main example I have is that we still don't know much (comparitively) about what signals are necessary for T-cells to turn into memory cells, and why some diseases or infections do not cause long-term immunological memory. The latter part is particularly relevant as the development of COVID vaccines progresses (I know the video is pre-COVID), and will likely be interesting to your audience in general.
    Again, I'm not suggesting you go into the insane complexity, but mentioning what we still don't know can give your audience a follow up if they want to learn more on their own.
    Oh yeah, and from an educator standpoint in terms of presentation, you people continually amaze me at how digestible your videos are. The color-coding part was genius, and even helped me get a more concise perspective on my own work.
    Fantastic job, and especially relevant today!
