Increased pore-forming claudins and decreased barrier-forming TJ components expression in the small intestine of HC and ASD subjects. Gene expression levels of TJ components in duodenal biopsies from HC (n = 9) and ASD patients (n = 12). CLDN-2, -10 and/or -15 levels are higher in eight out of 12 ASD samples, compared in controls. CLDN-1, OCLN, and/or TRIC levels are decreased in nine out of 12 ASD samples over controls. Each graph represents single patient results. Data are expressed as fold change over the averaged controls
