Common and unique differentially expressed genes, and gene ontology biological processes. (a) Genes significantly differentially expressed (p ≤ 0.05) in response to BLG, OVA or PNA sensitization. A total of 150 overlapping genes were commonly expressed among all of the antigen sensitized groups. (b) Gene ontology (GO) biological processes significantly (p ≤ 0.05) enriched with the genes from BLG OVA and PNA sensitized groups. A total of 46 overlapping biological processes were commonly enriched among all 3 allergen sensitized groups.
