Neuroinflammation Assay

Creative Biolabs' scientific team provides a wide range of neuroinflammation assays, which enable researchers comprehensively understand the neuronal pathology and screen potential drug candidates.

Background of Neuroinflammation

Neuroinflammation is characterized as the activation of the innate immune response of microglia and astrocytes in the central nervous system (CNS) in response to inflammation via enhanced levels of cytokines and chemokines as well as the production of intracellular reactive oxygen species (ROS). The homeostasis of neuroinflammation has a positive effect on the repair and functional recovery of the impaired brain. Although neuroinflammation plays a protective role in the brain temporarily, chronic neuroinflammation is considered one of the most important causative factors of neurological diseases, including neurodegenerative diseases, such as Huntington's disease, Alzheimer's disease, and Parkinson's disease, as well as psychiatric disorders, pain syndromes, and stroke. Neuroinflammation is a consequence of prolonged chronic stimulation of inflammation leads to recruitment of immune cells, woquleedema, tissue damage, and potential cell apoptosis. Overproduction of pro-inflammatory factors, including cytokines IL-1, IL-6, and TNF, as well as ROS, inducible nitric oxide synthase, etc., will result in a high degree of chronic neuroinflammation, which impairs the neural system.

Neuroinflammation Assay

It's critical to choose an appropriate assay to evaluate the key components that contribute to neuroinflammatory. At the early stage of the drug development program, an in vitro assay is an ideal protocol to learn the mechanisms of action of neuroinflammation. The general approach to detecting neuroinflammation is summarized in the following steps. First, induced pluripotent stem cells (iPSCs) are cultured to derive astrocytes and microglia. Then use lipopolysaccharides (LPS) or other pro-inflammatory agents to stimulate the in vitro cell cultures, which induces enhanced cytokine releases and nitric oxide production. After the LPS incubation, the cytokine levels released by iPSCs-derived astrocytes and microglia will be detected. Nitric oxide production can be determined by identifying the reduced nitrite in biological fluids in a microplate. By comparing to the control group, researchers could screen the prospective drug candidates.
