USP2 inhibition unleashes CD47-restrained phagocytosis and enhances anti-tumor immunity | Nature Communications
The CD47/SIRPα axis conveys a ‘don’t eat me’ signal, thereby thwarting the phagocytic clearance of tumor cells. Although blocking antibodies targeting CD47 have demonstrated promising anti-tumor effects in preclinical models, clinical trials involving human cancer patients have not yielded ideal results. Exploring the regulatory mechanisms of CD47 is imperative for devising more efficacious combinational therapies. Here, we report that inhibiting USP2 prompts CD47 degradation and reshapes the tumor microenvironment (TME), thereby enhancing anti-PD-1 immunotherapy. Mechanistically, USP2 interacts with CD47, stabilizing it through deubiquitination. USP2 inhibition destabilizes CD47, thereby boosting macrophage phagocytosis. Single-cell RNA sequencing shows USP2 inhibition reprograms TME, evidenced by increasing M1 macrophages and CD8+ T cells while reducing M2 macrophages. Combining ML364 with anti-PD-1 reduces tumor burden in mouse models. Clinically, low USP2 expression predicts a bett

Temporally discordant chromatin accessibility and DNA demethylation define short- and long-term enhancer regulation during cell fate specification
Guerin et al. present a highly resolved timeline of chromatin and DNA methylation dynamics during early neural progenitor cell differentiation. Their approach demonstrates that chromatin and DNA methylation mechanisms operate on different timescales to mediate short- and long-term gene enhancer regulation.
