Randomized trial evaluates TCR pathway's role in IFN-γ suppression in Treg cells, suggesting a new target for tumor immunity enhancement.

This research aims to understand how TCR signaling influences IFN-γ expression in Treg cells and its implications for anti-tumor immunity.
Performed genome-wide CRISPR/Cas9 loss-of-function screen in Tregs to identify genes affecting IFN-γ expression.
Transduced Tregs with sgZap70 and non-targeting control and assessed using RNA-seq for gene dynamics.
Conducted in vivo adoptive T-cell transfer tumor model to evaluate anti-tumor response.
CRISPR screening identified Zap70 as a key regulator of IFN-γ suppression in Tregs.
Genetic removal of Zap70 led to increased IFN-γ expression and activated IL-12 signaling pathway components.
Mice with Zap70-deficient Tregs showed reduced tumor burden compared to control groups.

Hua et al. (2026) studied this question.
