Nanoteranóstica e Medicina Personalizada

Abstract

“O fármaco certo, para o doente certo, no momento certo e na dose certa”, é um conceito-chave da medicina personalizada.Devido às limitações das estratégias convencionais de diagnóstico e tratamento surgiu recentemente o termo “medicina personalizada” com o objetivo de otimizar o tratamento, específico para cada doente, considerando a variabilidade interindividual na resposta à terapêutica para atingir a máxima eficácia com um elevado perfil de segurança.A teranóstica, que combina o diagnóstico e terapêutica num único sistema, pode contribuir significativamente para o desenvolvimento da medicina personalizada.Um dos possíveis agentes de teranóstico são as nanopartículas que, devido à sua elevada capacidade de carga, podem combinar funções de diagnóstico e terapêutica num único sistema.Nanopartículas poliméricas, dendrímeros, lipossomas, micelas poliméricas,nanopartículas de sílica, nanopartículas de óxido de ferro, nanopartículas de ouro e pontos quânticos têm sido investigados e são possíveis “nanoplataformas” para o desenvolvimento de nanopartículas teranósticas.A aplicação da nanoteranóstica na clínica permite a deteção precoce, o tratamento de doenças, bem como a monitorização da resposta ao tratamento, desempenhando assim um papel importante na medicina personalizada.Nesta monografia serão descritos os avanços recentes na tecnologia de imagem molecular e nanopartículas teranósticas, referindo as vantagens e desvantagens de cada modalidade de imagem, bem como das nanopartículas utilizadas na teranóstica. Por fim, será abordada a aplicação de nanopartículas teranósticas no diagnóstico precoce e terapia do glioblastoma.

“Right drug, right patient, right moment, right space, and right dose” is a key concept of the current personalized medicine.Due to the limitations of the standard diagnostic and therapeutic strategies, the term “personalized medicine” has recently emerged as a promising way to optimize treatment for each patient, considering the interindividual variability in the therapeutic response to achieve maximal efficacy along with a high safety profile.Theranostics, the integration of therapeutic and diagnostic capability in a single system, may significantly contribute to the ever-growing field of personalized medicine.Nanoparticles are one of the possible agents of theranostics that, due to their high loading capacity, are able to combine target therapeutic and diagnostic functions into a single system.Polymers, dendrimers, liposomes, polymeric micelles, silica nanoparticles, iron oxide nanoparticles, gold nanoparticles and quantum dots, have been previously investigated and are candidate nanoplatforms for building up nanoparticle-based theranostics.The clinical application of nanotheranostics will enable earlier detection, treatment of diseases and monitoring of therapeutic response, which is expected to play a significant role in the era of personalized medicine.In this monograph, the recent advances in molecular imaging technologies and theranostic nanoparticles will be described, exhibiting the advantages and drawbacks of each imaging modality and nanoparticles used in theranostics. Finally, the use of theranostic nanomedicines for early diagnosis and therapy of glioblastoma will be addressed.
