Self assembling peptides and peptidomimetics can be utilized for the treatment and support of disorders associated with leaky or damaged tight junction and weak, diseased, or injured extracellular matrix. The self-assembling materials generally have alternating hydrophilic or hydrophobic residues or hydrophobic and/or hydrophilic sections which allow the material to react or interact with the glycoproteins found in the ECM. Diseases in which treatment with these materials applied to or near the site in need of treatment include diabetic retinopathy, sepsis, burns, and certain neurodegenerative diseases such as Parkinson's and Alzheimer's. The formulations can be administered by injection, spraying, topically or by catheter or via a wound dressing or other material to which it is applied and then applied to the site in need of treatment.

Selon cette invention, des peptides et peptidomimétiques à auto-assemblage peuvent intervenir dans le traitement et le soulagement de troubles associés à une jonction serrée partiellement fonctionnelle ou endommagée et une matrice extracellulaire faible, malade ou lésée. Les matériaux à auto-assemblage comprennent généralement des résidus hydrophiles ou hydrophobes ou des sections hydrophobes et/ou hydrophiles qui permettent au matériau de réagir ou d'interagir avec les glycoprotéines présentes dans la matrice extracellulaire. Parmi les maladies traitées au moyen de ces matériaux appliqués sur le site nécessitant un traitement ou à proximité de celui-ci figurent la rétinopathie diabétique, la sepsie, les brûlures et certaines maladies neurodégénératives telles que la maladie de Parkinson et la maladie d'Alzheimer. Les formulations de cette invention peuvent être administrées par injection ou pulvérisation, par voie topique ou par cathéter ou par le biais d'un pansement ou autre matériau sur lequel lesdites formulations sont appliquées et qui est ensuite appliqué sur le site nécessitant un traitement.
