Immunological exhaustion: How to make a disparate concept operational?

PLoS Pathog. 2021 Sep 23;17(9):e1009892. doi: 10.1371/journal.ppat.1009892. eCollection 2021 Sep.

Abstract

In this essay, we show that 3 distinct approaches to immunological exhaustion coexist and that they only partially overlap, generating potential misunderstandings. Exploring cases ranging from viral infections to cancer, we propose that it is crucial, for experimental and therapeutic purposes, to clarify these approaches and their interconnections so as to make the concept of exhaustion genuinely operational.
