Inducing Neuroinflammation in Zebrafish Larvae with a Lipopolysaccharide Injection

Source: He, Y. et al. Brain Ventricular Microinjections of Lipopolysaccharide into Larval Zebrafish to Assess Neuroinflammation and Neurotoxicity. J. Vis. Exp. (2022). The video demonstrates the microinjection of lipopolysaccharides (LPS) into the brains of zebrafish larvae to induce neuroinflammation. The larvae are positioned on an agarose-lined dish, the needle is inserted into the brain ventricles, and the LPS is injected. The injected LPS triggers an immune response that leads to neuroinflammation.
