Descripción del proyecto
Un microscopio de superresolución para estudiar la virulencia bacteriana
El equipo del proyecto financiado con fondos europeos NanoVIB trabaja en el desarrollo de un microscopio de superresolución para determinar el origen celular de las enfermedades. Este novedoso microscopio tendrá una mayor resolución y profundidad de penetración, lo que permitirá identificar patrones de localización de proteínas y contextualizarlos a nivel celular. Los investigadores de NanoVIB emplearán esta tecnología innovadora para estudiar los mecanismos moleculares que subyacen a las enfermedades neumocócicas al centrarse en la interacción del agente patógeno con las células inmunitarias y las células hospedadoras. Esta parte del proyecto podría ayudar al diseño de tratamientos y vacunas contra las enfermedades neumocócicas.
Objetivo
In an interdisciplinary project, we will prototype a next-generation super-resolution microscope (SRM) and demonstrate its capability to bring about a major leap forward in our understanding of inter- and intracellular processes, and thus the cellular origin of diseases. Based on the recently invented MINFLUX concept, which pushes spatial resolution an order of magnitude beyond any other SRM technique, and by concerted development of detector technologies, lasers and image acquisition procedures, we will be able to retrieve information, not within reach by any other photonics-based technique. By extending operation to the near infrared, a hitherto un-accessible spectral range for SRM, we will strongly reduce phototoxicity and scattering, increase penetration depth and provide an additional spectral window for multiplexing. The developed prototype will allow nanometer-scale protein localization patterns to be resolved and to be placed in a cellular context by overlaid morphological, biochemical and metabolic images generated by label-free stimulated Raman scattering (SRS) and two-photon excitation (TPE).
In a lead application, we will use the unique capabilities of the to-be-developed technology to study the molecular mechanisms underlying pneumococcal disease, largely attributed to localization patterns of specific bacterial surface proteins, and their intricate interactions with immune and host target cells. Pneumococci are a major contributor to morbidity and mortality worldwide and we aim to provide vital information which can lead to new treatments and vaccines. We will also offer hands-on access to the technology to researchers from both academia and industry in an open demonstration facility. Together with the lead application, this will generate demand for microscopes, lasers and detectors, which the industrial partners will develop subsequent to this project based on the prototypes, further strengthening Europe´s industrial position in the microscopy field.
