Abstract
Despite the increasing use of silver nanoparticles in medical sciences, published studies on their interaction with nerve cells and evaluation of risks are dispersed. This systematic review and meta-analysis could be used to devise safety guidelines for the use of silver nanoparticles in industry and medicine to reduce adverse effects on the CNS.After extensive searches, the full text of 30 related studies was reviewed and data mining completed. Data were analyzed by calculating the mean of different ratios between treated and untreated groups. Linear regression between variables was evaluated by meta-regression. Subgroup analysis was also performed due to heterogeneity.Treatment with silver nanoparticles significantly reduced cell viability (SMD = -1.79%; 95% CI: -2.17 to -1.40; p < 0.0001). Concentration > 0.1 μg/mL could kill neurons, while lower concentration would not (SMD -0.258; 95% CI: -0.821 to 0.305; p = 369). In addition to the concentration, the coating, size of the nanoparticles, and cell type are also factors that influence SNP nerve cell toxicity. Measurement of apoptosis (SMD = 2.21; 95% CI: 1.62 to 2.80; p=0.001) and lactate dehydrogenase release rate (SMD = 0.9; 95% CI: 0.33 to 1.47; p < 0.0001) also confirmed the destructive effect of silver nanoparticles on nerve cells.
期刊介绍:
Reviews of Environmental Contamination and Toxicology publishes reviews pertaining to the sources, transport, fate and effects of contaminants in the environment. The journal provides a place for the publication of critical reviews of the current knowledge and understanding of environmental sciences in order to provide insight into contaminant pathways, fate and behavior in environmental compartments and the possible consequences of their presence, with multidisciplinary contributions from the fields of analytical chemistry, biochemistry, biology, ecology, molecular and cellular biology (in an environmental context), and human, wildlife and environmental toxicology.
•Standing on a 55+ year history of publishing environmental toxicology reviews
•Now publishing in journal format boasting rigorous review and expanded editorial board
•Publishing home for extensive environmental reviews dealing with sources, transport, fate and effect of contaminants
•Through Springer Compact agreements, authors from participating institutions can publish Open Choice at no cost to the authors
