CCR2 and achalasia-alacrima syndrome: A prominent more CCR2 signal was observed at the MIRA in surgical AAAs when compared to both the non-surgical AAAs (Ab MIRA 0.7 ± 0.2 vs. 0.28 ± 0.1 respectively, P < 0.001; MIRA 0.71 ± 0.2 vs. 0.34 ± 0.1 respectively, P < 0.001 and Be MIRA 0.73 ± 0.2 vs. 0.54 ± 0.3 respectively, P = ns; Figure 3B) and non-AAA controls (Ab MIRA 0.24 ± 0.07, P < 0.0001; MIRA 0.29 ± 0.07, P < 0.001 and Be MIRA 0.34 ± 0.1, P < 0.001; Figure 3B).
