Abstract

The Multiple Sclerosis (MS) is an inflammatory, autoimmune and demyelinating disease with prevalence in female young adults. Concerning the actual knowledge about the disease, it is known that auto-reactive antibodies act against myelin's proteins and up to now, there is no efficient method to previously diagnose MS. In this context, it is imperative the investigation of an accurate diagnostic method for obtaining precise and early results. The present project intends to use the Atomic Force Microscopy (AFM) to develop sensitive immunonanosensors in order to measure the antigen-antibody chemical interaction mechanisms involved in the MS immunopathogeny. Additionally, by combining molecular modeling techniques and experimental approaches it is expected to achieve the target amino acids sequences direct related to MS. Consequently, it will be possible to measure the energy of that antigen-antibody complex. The uniqueness of this project relies on the use of a technique that focus the immobilization of the antigen-antibody complex on nanosurfaces (AFM apparatus) to detect MS target molecules identification. It is also included the availability to combine the results between the data obtained at the experimental analysis with the ones from computational simulation. (AU)
