"These cells are known to mistakenly attack healthy tissues in patients with autoimmune diseases," Er, wrong. Nobody has ever found T cells mistakenly attacking healthy tissues in autoimmune rheumatic disease as far as I know. This is plain ignorant but typical. Actually, when people with rheumatoid disease were given Campath-1 all their T cells disappeared for years - decades I think now. It did not seem to affect their immune competence much but it made no difference to the arthritis.
I think this is the study: Canagliflozin impairs T cell effector function via metabolic suppression in autoimmunity Canagliflozin impairs T cell effector function via metabolic suppression in autoimmunity: Cell Metabolism
