Differential expression levels were expressed on a fold change basis (FC, signal from B deficiency/signal from B sufficiency). Background correction and normalization of expression data were performed as already described.14 p-values for all FC shown were lower than 0.05 and considered statistically significant according to Student’s t-test.
