Advances in the use of nanocarriers for cancer diagnosis and treatment

Abstract: The use of nanocarriers as drug delivery systems for therapeutic or imaging agents can improve the pharmacological properties of commonly used compounds in cancer diagnosis and treatment. Advances in the surface engineering of nanoparticles to accommodate targeting ligands turned nanocarriers attractive candidates for future work involving targeted drug delivery. Although not targeted, several nanocarriers have been approved for clinical use and they are currently used to treat and/or diagnosis various types o… Show more

“…However, several liposomal drugs are either approved for clinical use or in clinical trial studies (Table 1). [48][49][50][51][52][53][54][55][56][57][58][59] Optimizing the ideal liposome for crossing the BBB has important implications for the treatment of neurological diseases. Different liposomal formulations and strategies have been developed for enhancing drug delivery across the BBB.…”

“…O endotélio vascular normal possui cerca de 5 a 10 nm de distância entre suas fenestrações (aberturas entre as células), enquanto os novos vasos, que surgem por causa da angiogênese tumoral 10 e da alta necessidade de nutrição 11 , possuem tamanhos entre 100 a 780 nm 10 . Esse tipo de utilização das NP é conhecido como Enhanced Permeability and Retection (EPR) ou vetorização passiva voltada para o acúmulo dessas NP no endotélio neoplásico 9 .…”

“…Em virtude da heterogeneidade do câncer, novas estratégias que abordam os processos de morte neoplásica estão sendo avaliadas 5 , abrindo espaço para a utilização das NP que amenizam efeitos colaterais disseminados das quimioterapias 6 por causa da sua especificidade direcionada ao tecido tumoral e da sua maior absorção 7,8 . As NP são moldadas para conseguirem se depositar em locais de inflamação ou tumorais por causa do afastamento das células endoteliais, característico do tecido neoplásico 9 . O objetivo geral deste trabalho é avaliar as principais propriedades das NP de proteína, metal, polímero e lipídio, suas estruturas, utilizações e suas limitações e vantagens contra células cancerígenas.…”

“…For example, using Herceptin targeted NPs helped to differentiate human epidermal growth factor receptor 2 (EGFR), human epidermal receptor-2 (HER2) positive and (HER2) negative breast cancer cells. Clearly, the active targeting of HER2 receptors on the over-expressed cells with NPs was confirmed 30 .…”
