DIAMANTE (Nano-Technologies for Autoimmune Disease) is a biotech company focused on the use of plants for producing high value-added molecules. The company was funded in 2016 with the development of new tools in autoimmune disease diagnosis and now we are growing approaching therapeutics applications. As an innovation-oriented female company, our value proposition is the creation of novel therapeutic approach for autoimmune diseases based on the restoration of self-tolerance, using plant viruses displaying immunodominant peptides. Diamante, thanks to the Regione Veneto and particularly though the national grant POR FESR AZIONE 1.1.1 2020/2021, has achieved important results in the diagnostic field for the Rheumatoid Arthritis (RA). This project allowed the company to increase the team with two more specialized people and to develop a specific technology platform for the RA diagnoses.
