PERK RNAi

PERK RNAi refers to the use of RNA interference (RNAi) to silence the expression of Protein Kinase RNA-activated-like ER Kinase (PERK), also known as EIF2AK3. PERK is a key transmembrane protein located in the endoplasmic reticulum (ER) that acts as a sensor for the Unfolded Protein Response (UPR). In oncology research, PERK signaling has been identified as a critical driver of T-cell exhaustion and dysfunction within the tumor microenvironment. Research conducted at Wake Forest University has demonstrated that inhibiting PERK expression via RNAi in cytotoxic T-cells can enhance their ability to clear cancer cells, particularly under conditions of ER stress. This approach is being investigated as a potential strategy to overcome resistance to immune checkpoint inhibitors, such as ipilimumab, by restoring T-cell effector capabilities and preventing the metabolic and signaling shifts associated with exhaustion.
