Varying expression of splicing factors in the CD4
subtypes. Expression levels of genes known to encode proteins involved in pre-mRNA splicing are presented as Z-scores. Colours to the left of the rows indicate the subtype that SU genes were assigned to as follows. Naive, red; Th1, blue; Th2, green, Th17, purple, Treg, orange; iTreg, yellow. The list of splicing factors was taken from Chen et al.  and mouse orthologues of human genes were found by searching the Mouse Genome Database .
