IKZF2, a transcription factor in the Ikaros family, plays a key role in stabilizing regulatory T (Treg) cells and promoting immune suppression within the tumor microenvironment (TME). Selective targeting of IKZF2 in intratumoral Tregs has the potential to enhance antitumor immunity and improve the efficacy of immunotherapy, while minimizing immune-related toxicities associated with systemic Treg depletion.
