Introduction

The nervous system is very sensitive to many toxic compounds and harmful substances produced in the natural environment. In the course of the disease, neurotoxicity can cause temporary or continuous damage to the brain or peripheral nervous system. At the same time, neurotoxicity is also the main cause of many neurodegenerative diseases such as Alzheimer's and Parkinson's.

Solutions for You

In the process of drug discovery and development, neurotoxicity is a non-negligible cause of failure. Most drugs have neurotoxic effects mediated mainly by several dopaminergic and glutamatergic neurotransmitter systems. Although many researchers have investigated the medical and cognitive consequences of drug abuse, the neurotoxicity caused by these drugs still requires full attention. Creative Bioarray offers a one-stop-solution for neurotoxicity screening.

Neurotoxicity screening

The content of basic neurotoxicity screening should include specific histopathological examination and systematic clinical evaluation.

  • Specific histopathological examination
Specific histopathological examination of tissue samples representing all major areas and elements of the brain, spinal cord and peripheral nervous system.
  • Systematic clinical evaluation
Systematic clinical evaluation of laboratory animals uses a clearly defined series of clinical tests and observations. These experiments and observations were selected to detect major neurological diseases, behavioral abnormalities, physical dysfunction and any other signs of neurotoxicity.

Effect characterization

  • Neurotoxicity test

After screening a chemical substance that has an adverse effect on the nervous system, the next stage of testing focuses on determining the chemical substance's effect on the nervous system and its properties (characterization). At this level, the neurotoxic effects found in the screening process will be further characterized, and research will be conducted to determine whether the test chemical has any other possible subtler effects on the structural and functional integrity of the nervous system of mature and developing organisms. The in-depth assessment of neurotoxicity during this testing phase should include:

  1. The nature and severity of the effect.
  2. Information on the time pattern of the onset of the effect (especially when delayed neurotoxicity occurs) and the duration of the effect.
  3. More detailed histopathological examination (including the use of special stains to highlight related nerve structures).
  • Response Relationships
The no-observed-adverse-effect level (NOAEL) is a key element in defining the neurotoxic hazard of chemicals. In order to determine the NOAEL more quantitatively, the most relevant and sensitive endpoints are usually used for research.

In vitro models for neurotoxicology studies

  • Primary cells: neurons and glia (microglia, oligodendrocyte, astrocyte) from different brain regions
  • Cell lines: neuroblastoma, astrocytoma, glioma, pheochromocytoma
  • Brain slices: hippocampus
  • Reaggregating neuronal and glial cell cultures
  • Organotypic (3D) cultures; usually co-cultures (more than one type of cell)
  • Neural stem (progenitor) cells: primary cell cultures and cell lines
  • Induced pluripotent stem cell(iPSC)
