The present invention provides a method of diagnosing or predicting susceptibility to a clinical subtype of Crohn's disease characterized by fibrostenosing disease by determining the presence or absence in an individual of a fibrostenosis-predisposing allele linked to a NOD2/CARD15 locus, where the presence of the fibrostenosis-predisposing allele is diagnostic of or predictive of susceptibility to the clinical subtype of Crohn's disease characterized by fibrostenosing disease. In a method of the invention, the clinical subtype of Crohn's disease can be, for example, characterized by fibrostenosing disease independent of small bowel involvement. The invention also provides a method of optimizing therapy in an individual by determining the presence or absence in the individual of a fibrostenosis-predisposing allele linked to a NOD2/CARD15 locus, diagnosing individuals in which the fibrostenosis-predisposing allele is present as having a fibrostenosing subtype of Crohn's disease, and treating the individual having a fibrostenosing subtype of Crohn's disease based on the diagnosis.

Bronchial remodelling is a prominent feature of severe asthma and a potential therapeutic target. Some data indicate that Th17 cytokines in particular IL-22 may be involved in remodelling processes in vitro, and in skin remodelling in vivo. The aim of the inventors was to evaluate if Th17 cytokines are involved in bronchial remodelling in a severe model of allergic asthma, and if this was amplified by co-sensitization with NOD2 agonist, MDP, a ligand favouring Th17 polarization. Dog allergen challenge led to a predominant neutrophilic infiltration in Broncho-alveolar lavage (BAL), increased dog-specific IgE production, airways hyperresponsiveness, and increased Th17 cytokine production. Increased bronchial remodeling was observed in dog allergen challenged mice compared to control. IL-22 deficiency decreased airway hyperresponsiveness, bronchial mucus production as well as peribronchial collagen deposition, in the allergen-challenged group. Th17 cytokines in particular IL-22 participate in the bronchial remodeling in a chronic model of neutrophilic asthma, and may represent a therapeutic target in severe asthma.
