It is well established that antigenic proteins are processed in the proteasome of antigen-presenting cells by simple proteolysis to produce antigenic peptides that can be presented to T cells. As Cresswell explains in his Perspective, two recent papers, published here ( Vigneron et al.) and elsewhere, provide an extra layer of complexity to the story with their revelation that two tumor antigenic peptides were formed by a more complicated splicing process in the proteasome.
