    I like to think of opsinization as "honey" that makes the target pathogen more delicious to phagocytes. Visual: bees to honey. "Bee"-cells respond, make honey, to attract "b"ears to eat them.

    Thank you for this wonderful presentation.
    i am wondering about the recognition receptor proteins on the B-cells and helper T-cells.
    lessons on immune system often begin with a B-cell receptor proteins recognizing the antigen/foreign particle. But how did that receptor protein get there? You mentioned there are 10^10 possible combinations. So is it just by chance that there will be a receptor protein on some of your B-cells to recognize every kind of antigen out there?

      I like that he explains the meaning of the words and everything.
      Of you just spit out a bunch of names & deliver it in a very dry way, it doesn't get memorized. So it's like he makes a little story for each section of what he is explaining & think that's why his method works so well :)
