MBP and eosinophilic esophagitis: A merged photomicrograph of DAPI-mounted anti-MBP and anti-VIP-stained tissue sections shows eosinophils nearby VIP-expressing nerve cells (Figure 6a(iv)) and anti-tryptase and anti-VIP mast cells nearby nerve cells in the esophageal tissue sections of our DOX-exposed CC-10-IL-13 mouse model of EoE (Figure 6b(i–iv)).
