Writing in Nature, Yamamoto et al. reveal a mechanism that enables pancreatic cancer cells to evade an immune response. The process implicated is usually associated with the normal degradation and recycling of cellular proteins. The authors find that inhibition of this pathway, using drugs or by genetic approaches, reverses this immune evasion in animal models of pancreatic cancer. The finding provides a compelling rationale for investigating whether targeting this pathway might be of benefit in the clinic. Read more . . .
