Schwann Cells and Dorsal Root Ganglion Neurons Are Differentially Susceptible to Oxidative Stress Induced by Silicon Dioxide Nanoparticles

Lai J.C.K., Jaiswal A.R., Idikuda V.K., Pfau J., Bhushan A., Leung S.W., Idaho State University College of Pharmacy, US

Silicon dioxide (SiO2) particles, including nanoparticles, have been increasing employed in diverse industrial and biomedical applications including those in drug formulations, food, and cosmetics as SiO2 has been generally regarded as a non-toxic substance. However, [...]

Molecular Effects of Silicon Dioxide Nanoparticles on Cell Survival Signaling of Dorsal Root Ganglion (DRG) Neurons and Schwann Cells

Jain A., Jaiswal A.R., Lu S., Wong Y.Y.W., Bhushan A., Leung S.W., Daniels C.K., Lai J.C.K., Idaho State University, US

The molecular mechanisms underlying the pathophysiology of peripheral neuropathies have not been fully elucidated. To meet the need for suitable cell culture models in vitro of peripheral nervous system (PNS) neural cells that allow long-term [...]

Effects of Silicon Dioxide Nanoparticles on Peripheral Nervous System Neural Cell Models

Jaiswal A.R., Lu S., Pfau J., Wong Y.Y.W., Bhushan A., Leung S.W., Daniels C.K., Lai J.C.K., Idaho State University, US

Cell model systems in vitro facilitate the high through-put screening of putative toxicity of a variety of nanomaterials, including nanoparticles. However, most of such cell models consisted of non-neural cells. We have developed several central [...]

Silicon Dioxide Nanoparticles Exert Dissimilar Cytotoxic Effects on Mammalian Cell Types

Jandhyam S., Lai J.C.K., Lai M.B., Dukhande V.V., Bhushan A., Daniels C.K., Leung S.W., Lai J.C.K., Lai M.B., Idaho State University, US

Applications of nanomaterials (e.g., silicon dioxide (SiO2) nanoparticles) are ubiquitous. Thus, environmental and occupational exposure to these nanoparticles could pose potential health risk. SiO2 microparticles are toxic in animals in vivo and SiO2 nanoparticles are [...]
