Abstract: The present application provides compositions and methods for treating acute lung injury and acute respiratory distress syndrome. The methods include administering one or more tight junction antagonists to the lung of a subject in need thereof.

Abstract: Compositions, methods of making compositions and methods of treating cough are described herein. In some embodiments, the compositions are lozenges comprising memantine and an alkalinizing agent.

Abstract: Memantine compositions and methods of use are described herein. In some embodiments, the compositions comprise memantine and an absorption enhancer, or memantine and an elimination enhancer, or memantine and an absorption enhancer and an elimination enhancer.

Abstract: Enteric compositions comprising one or more tight junction agonists and/or one or more tight junction antagonists are provided. Compositions of the invention may comprise a delayed-release coating disposed over a tight junction agonist and/or tight junction antagonist layer which may be disposed over an inert core. Delayed-release coatings may be substantially stable in gastric fluid and substantially unstable in intestinal fluid, thus providing for substantial release of the tight junction agonist and/or antagonist from the composition in the duodenum or jejunum of the small intestine.

Abstract: The present invention provides materials and methods for the treatment of inflammatory bowel disease (e.g., Crohn's disease and ulcerative colitis). Materials of the invention may include compositions comprising one or more tight junction antagonists and optionally one or more therapeutic agents. Methods of the invention may comprise treating a subject in need thereof with a composition comprising one or more tight junction antagonists and, optionally one or more therapeutic agents.

Abstract: The present invention provides materials and methods to diagnose asthma. In some embodiments, the present invention provides a method of diagnosing asthma by measuring the zonulin level of a subject. The present invention also provides methods and compositions for treating asthma that comprise one or more zonulin antagonist.

Abstract: The present invention provides materials and methods to facilitate the pulmonary delivery of therapeutic agents. In some embodiments, agonists of tight junctions (e.g., zonulin agonists) are used in compositions to facilitate the uptake of therapeutic agents from the pulmonary mucosa.

Abstract: The present invention provides methods and materials, including kits, to evaluate Crohn's disease, including to diagnose, monitor, or determine the efficacy of treatment for Crohn's Disease. The methods involve determining the presence, absence, or level of zonulin in a subject sample. In certain embodiments, the need for more laborious and/or invasive tests to monitor disease state is minimized or obviated.
