Visual display of selected treatment (imiquimod)-specific transcripts (complete database available on line). (a) Display of selected primary treatment-specific genes identified as per Figure 2. (b) Secondary treatment-specific genes related to effector functions with primary focus on cytokines, cytokine receptors and lytic enzymes. (c) Secondary treatment-specific genes representative of cell surface markers, receptors and associated molecules. In red are genes whose expression was found to be associated with acute renal allograft rejection . Treatment cohorts are described by the bars on top of each cluster.
