WebMar 25, 2024 · TOX is a member of a family of transcriptional factors that contain the highly conserved high mobility group box (HMG-box) region. Its expression is upregulated in dysfunctional T cells, driven by chronic T cell receptor stimulation and activation of transcription factors known as nuclear factor of activated T cells (NFATs). WebTOX is largely dispensable for the formation of T eff and T mem cells, but it is critical for exhaustion: in the absence of TOX, T ex cells do not form. TOX is induced by calcineurin and NFAT2, and operates in a feed-forward loop in which it becomes calcineurin-independent and sustained in T ex cells.
