“…Gluten, the storage protein of wheat, is the environmental inducer of the disease in addition to other structurally related molecules found in barley, rye, and oat (Lerner, 2014 ). Many environmental factors were suggested to induce or enhance the disease: multiple infections (Lerner and Reif, 2015 ), early infections (Myléus et al, 2012 ), early gastrointestinal infections (Beyerlein et al, 2017 ), lack of breast feeding (Lerner and Matthias, 2016c ), time and amount of gluten consumption (Chmielewska et al, 2015 ), microbiome/dysbiome repertoire (Lerner et al, 2015a ; Lerner and Matthias, 2017a , b ), mode of delivery (Decker et al, 2011 ), early vaccination (Kemppainen et al, 2017 ) or early consumption of antibiotics (Canova et al, 2014 ) and geo-epidemiological influences (Lerner, 1994 , 2015 ; Reif and Lerner, 2004b ; Lerner and Matthias, 2015a ). The abnormal immune response is directed, in particular, against tissue transglutaminase (tTG), representing the autoantigen, (Reif and Lerner, 2004a ; Lerner et al, 2015c ) and the two main autoantibodies, anti-endomysium and anti-tTG antibodies, are the most prevalent serological markers used to screen for the condition (Shamir et al, 2002 ; Lerner and Matthias, 2015d ).…”
