In a re-analysis of five transcriptomic datasets, including those from Liaoet al. [59] and Lockstoneet al. [46], the same authors show that “programmed cell death (PD)-1/PD-L1 cancer immune therapy” and “neuro-inflammation” gene sets were the most consistently upregulated sets, comparing progressive to nonprogressive sarcoidosis (five datasets from five studies). Here, CD274 is linked to sarcoidosis.
