As far as I know and could understand from reading about HIV, T helper cell is one of the main reasons to develop AIDS in patients infected with HIV virus, that because the absence of helper T cell suppresses the immune system because no T cell cytokines released to allow other white blood cells to attack or release antigens.
Q1. Did I understand it correctly?
Q2. Now if my understanding is correct, why don't scientists find a way to produce T cell cytokines in the lab? and then inject it to patients with HIV? wouldn't that in theory revive the immune system and perhaps heal them or at least make them live longer?
P.S. My knowledge is close to nothing in this topic, so excuse me if the question itself is wrong :)
