Tai sitten se on pikemminkin seurausta immunoaktivaatiosta eikä syy. Rapatessa roiskuu.
Linkkisi; ”It is presumed that these are related to bystander effects from T cell activation. If patients are responding to therapy, they may be more likely to have irAEs as their immune system is more competent or if there is cross-reactivity between tumour and normal tissues, i.e., common antigens. Some have postulated a response-independent effect, where organs may have subclinical inflammation which progresses when PD-1 axis inhibition is introduced”
Edelleen: ”development of early autoimmune manifestations due to reduced tolerance to self-antigens following treatment with ICIs may indicate heightened activation of the endogenous anti-tumour immune response and represent an important factor in evaluating potential benefit from therapy.”
Faronin havainnoissa nuo ”pre-treatment autoantibodies” ja parempi survival viittaisi myös siihen, että immuniteetti on yhä aktiivinen, niin omia kudoksia kuin syöpää vastaan.
