This was brilliant. I was using the Kuby Immunology text book which I felt was just over complicating the whole process and was very unclear as to what the two signals were. This video fixed all that in 5 minutes and was short and sweet!

i think the activation of CD8 t-cells most often require the help of a cd4 t-cell (which produces the IL-2 that reaches the CD8 t-cell and induces its proliferation)? its like: cd4 t-cell and cd8 t-cell are bound to antigens on one APC.. at least thats whats written in janeway immunobiology book: the CD4 T-cell stimulates the APC to increase co-stimulatory molecules like 4-1BBL and b7 and this co-stimulates at the same time the CD8 T-cell bound to the APC and leads to the activation.. and IL-2 leads to the proliferation.. or am I wrong and thats a different process?.. i am a bit confused :(

do activated t-cells PERMANENTLY release Cytokines or just when an MHC binds to it

@glaucovitiello41954 жыл бұрын
Hi, Toulin! Activated T cells are short-lived cells. After activation in the lymph node, these cells migrate to peripheral tissues where they will exert their functions. If it's a CD4 T cell, it will recognize their cognate antigen on antigen presenting cells via MHC-II and secrete cytokines (necessary for activate macrophages if it's a Th1 cell or to isotype switch if its a folicular T cell or a Th2 cell, for example). The antigen is a survival signal for these cells and on the absence of the antigen recognition they die, and just memory T cells remain, which will be activated rapidly upon a next contact to the same antigen, but do not secrete cytokines at resting. The deletion of activated cells after antigen removal is part of immune homeostasis and is necessary to prevent overactivation of the immune system. So, shortly answering your question, cytokine secretion is boosted upon antigen recognition, despite their start secrete basal levels of these cytokines after activation. After antigen clearance by effective immune response these cells die. Hope it helped! ;)

@@glaucovitiello4195 Thank you so much for answering. So you are basically saying that activated t cells secret basal levels of cytokines but if they bind to an antigen the cytokine production is induced and they start to secrete more?
