Abstract
Mycobacterium avium subspecies paratuberculosis (MAP) has been implicated in the pathogenesis of Crohn's disease (CD). The role of CD susceptibility genes in association with these microbes is not known. Sixty-two early onset paediatric CD patients and 46 controls with known MAP status were analysed for an association with 34 single nucleotide polymorphisms (SNPs) from 18 CD susceptibility genes. Functional studies on peripheral blood mononuclear cells (PBMCs) were conducted on 17 CD patients with known CD mutations to assess IL-6, IL-10, and TNF-α expression upon stimulation with MAP precipitated protein derivative (PPD) and lipopolysaccharide (LPS). In addition, surface expression of IL10R..
