摘要
Dear Editor,Tumors evade immune surveillances,in part via negative regulatory pathways(also called checkpoints)that also regulate immune toleranee to autoimmunity(Thommen et al.,2018).Checkpoint inhibitor therapy,i.e.,anti-CTLA-4 and anti-PD-1,has been approved to be an effective therapeutic approach in a variety of cancers(Mariathasan et al.,2018).However,only a subset of cancer patients shows durable responses(Callahan et al.,2016),urging for a broader investigation beyond PD-1 and CTLA-4.
