Highly coordinated expression of MHC class II classical and nonclassical molecules, invariant chain, and the master transactivator CIITA in individual DLBCL patients including those with the overall 10% lowest expression (arrows). The 50 patients with the shortest survival times of the 240 in the LLMPP DLBCL data set are shown from left to right. The x-axis shows each individual patient by study ID number, whereas the y-axis shows relative expression of genes (log 2).
