Altered Esophageal Mucosal Structure in Patients with Celiac Disease

Figure 2

Example of immunofluorescent staining in the esophageal mucosa of a healthy control (C), a CD patient without RS (CD), a GERD patient, and a CD patient with reflux symptoms at the time of diagnosis (CD + RS) (magnification 20x). tTG2 (red); IgA deposits (bright green, perivascular, long arrows); IgA-TG2 deposits (orange/yellow, short arrows); s.e.: squamous epithelium; l.p. = lamina propria. Dull green background in C and GERD due to autofluorescence and nonspecific staining.
