@@kristeenbarker After 4 years of med school, 3 years of IM residency, and now nearly 2 years of Rheum fellowship, I've FINALLY been able to wrap my head around immunology concepts because of you and your videos!😍 I don't just 'get' the concepts, I *UNDERSTAND* them, and can apply them (which you know, is just a bit important 😅). The way you explain and visualize things works so well for my neurodivergent brain - I'm beyond excited. I'm so happy to have made your day, because for real, you've made my fuckin' month (and very likely more)!! I look so forward to whatever other videos you make! :)

Amazing explanation! Hence, in chronic autoimmune diseases, are the autoantibodies produced by plasma cells or memory B cells? Does this depends on the type of disease?

Niccolo, this is such a fascinating question. As i was researching this, i understood the B cells (at last) then I started to question how rituximab even works because it doesn't target plasma cells after all - and so there's something more to this - I'm hoping to get to the bottom of this question at some stage but please let me know if you find clarity before i do! :) Immunology = a journey!

@@kristeenbarker Kristeen what a wonderful reply! I will definitely let you know and I thought about the same thing given that, as you said, Rituximab does not work on plasma cells. I am on an impossible mission of curing my own multisistemic autoimmune (in part) diseases (MECFS, POTS and Autonomic SFN). I am sure there is a lot of work to be advanced in research. 😊May I ask you, given my ignorance, do B cells become eventually plasma cell? And if so, how long does the whole process take? I am sure the answer will be not straightforward. 😅 Thanks again!

@@niccolowrld they say patients are experts in their own condition, and i very much hope your journey leads you to cure. So some b cells become plasma cells, some remain as memory cells and can become plasma cells later. in terms of timeline, i'm not sure exactly - will be slower the first time the B cell sees the foreign particle, and it will switch from IgM antibodies to IgG antibodies along the way, so it's sort of days-weeks initially. Memory B cell can spring into action much faster (the rationale for vaccination) - hope that helps and again my best wishes for your health. Kristeen

Are the HLA class 2 antigens present on HLA class 2 presenting cells heterogeneous for the possible combinations of each inherited allele within the same cell, or does each HLA class 2 presenting cell only present one variant ( ie: allelic exclusion or clonal expression for a given clone of B cells or a given histiocyte or dendritic cell) ?? My question is the same for HLA class 1 cells (?).
