Реферат:
Certain nanomaterials of organic or inorganic nature, as well as some viruses, are capable of translocating from the nasal cavity into the brain bypassing blood-brain barrier (BBB). For example, nanoparticles (NP), such as carbon, gold, metal (manganese, iron, titanium) oxides, etc., could reach deep brain structures after administration into the nasal cavity. Upon intranasal administration, NPs accumulate mainly in the structures of olfactory system, especially in olfactory bulbs and anterior olfactory nuclei. On the one hand, NPs are attractive "platform" for the development of non-invasive nose-to-brain drug delivery systems, and magnetic resonance imaging (MRI)- or radiocontrast agents for neuroimaging. But, on the other hand, potential neurotoxicity of air dispersed nano-pollutants raises significant concerns as a risk factor for dementia and other neurol. disorders. Thus, it is crucial to detail accumulation patterns of nose-to-brain transport of NPs both qual. and quant. In this study, we investigated the distribution of NPs through the layers of mouse olfactory bulb after their intranasal administration. To address this, we prepared neg. charged manganese oxide nanoparticles (MnFe2O4-NPs) and platinum oxide particles (PtO-Ps), which were efficiently transmitted from the nasal cavity into the brain. Because the intensity of T1 -weighted MRI signal of MnFe2O4-NPs strongly correlated with Mn concentration in brain structures, this allowed high-resolution quant. tracking of NP's brain trafficking with 11.7 T MRI. To estimate the extrapolation of the obtained distribution patterns, we intranasally administered PtO-Ps, available for detection in the brain tissues by transmission electron microscopy (TEM) and micro-X-ray fluorescent anal. (micro-RFA).
