Type of Research Project
- Basic science
What is the background of the project?
Excitotoxicity is a biological process characterized by severe neuronal stimulation by glutamate. This over-stimulation by glutamate or other stimulation induces an excessive influx of calcium ions, triggering the activation of enzymes and cell death. This process is associated with certain diseases as stroke, traumatic brain injury, multiple sclerosis, Alzheimers disease, epilepsy, Parkinsons disease and Huntingtons disease. Excitotoxicity could induce functional deficits, such as impaired cognition and motor skills. However, its necessary to characterize different types of excitotoxic stimuli for use in preclinical research. The quinolinic acid (QA) is used as an excitotoxic stimulus activating NMDA-receptors and its administration in the striatum of animals is used to induce neuronal death. Little is known about the core end after peripheral administration of a drug. Thus, it is required characterization of the effect of systemic administration of QA on behavioral changes, as well as on the cell viability and activation of glial cells.
What is the aim of the project?
The objective of this project is to evaluate the effect of intraperitoneal administration of QA on memory, motor behavior, neuronal death and microglial activation.
