Periodic Reporting for period 1 - ICARO (Intracellular Carrier Against Resistant microOrganisms (ICARO))
Reporting period: 2022-04-01 to 2023-03-31
ICARO take advantage of MEMS capabilities to obtain the proof-of-concept for a new generation of vaccines needed for diseases caused by intracellular pathogens (viruses, bacteria and protozoa) with a high societal impact. The biochips technology underlying this project has been already proven: biochips are optimal to reach and work in the intracellular environment: volume in the range of μm3, easy to manipulate, proven internalization by phagocytic and non-phagocytic cells and the ability to remain long period of time in the cell. Our vision is to develop silicon microchips that will cross the cellular barriers carrying antigens for its presentation.
By achieving that, ICARO might be a ground-breaking new vaccination strategy to boost T cells responses by a rapid scouting of a repertoire of antigens for a given pathogen. We aim to develop standardized methods for ICARO manufacturing and functionalisation to be easily applicable to other pathogens, thus accelerating the generation of new vaccines in the future.
In order to realize the project impact, the consortium has already achieved initial promising results which show the feasibility of the chips manufacturing and the viability of different pathogen immobilization protocols as the first steps of our science-towards-technology effort. In addition, the consortium is starting to characterizing the internalization of the chips and how different sizes, geometries and type of chips may impact on the internalization of the loaded chips. In the following reporting periods, the consortium will answer the most relevant questions in the project, especially in vivo toxicity and efficacy. The consortium has confirmed the good perspectives for protecting a broad concept of the use of silicon-chips loaded with whole (or part of) pathogens as an immunization strategy in the context of infection.
