Cipa Assay And Its Uses In Technology And Medicine

The comprehensive in vitro cerebral palsy assay (CIPA) is a mechanism-based method for testing potential drug liability. The cipa test measures changes in channel activity and the intracerebroventricular infusion of voltage-sensitive potassium channels blockers as an independent measure of chloride permeability and as a measure of potassium leakage. The first cipa assay measures effects on human cloned human ventricular myocytes. Since these cells form the majority of the human brain’s muscle mass, they are particularly relevant in tests of central nervous system function.

Managing The Use Of CIPA Assay

The second cipa assay for Alzheimer’s involves the use of a potassium current in the presence of cloned mouse cardiomyocytes. In this set of experiments, investigators use a novel labeling procedure to identify individual myocytes. One particular compound, shown to have weak affinity for the human tetracycline sulfate receptor, is administered intravenously to test Alzheimer’s-like behaviors in animals. Another compound, ketaser cyanide, is given in the presence of a weakly binding agent that prevents the entry of sodium chloride into cells. Other compounds that may have similar effects as the neurotoxic compound, such as benzodiazepines and other anesthetic drugs, are administered intramuscularly.

A third experiment employs cipa to test relationships between genetic differences in human cord blood mononuclear cells and their ability to generate disease states in people who suffer from Alzheimer’s. The cipa assay is performed using cells from the human placenta, which are differentiated during early development and referred to as field potentials. These cells fail to express or develop certain genes in response to specific treatments, such as some types of medication or radiation. Using this method, researchers can separate cells with different functions and study their responses to hypnosis, hypnotherapy, or mild electrical current. This study is currently undergoing clinical trials.

Results Gathered From Dedicated Research

One group of researchers has sought to use cipa to test the effect of mild electrical current on the action potentials of cardiomyocytes – also known as the myocardium – in people who suffer from cardiac arrhythmias. Myocardial infarction (MIF) is associated with a high risk of death in patients with cardiovascular disease, and this potential can be blocked. In previous studies, cipa was shown to prevent cardiac arrest in people with acute myocardial infarction or heart failure by preventing an increase in the activity of the myocardium. Other potential applications of the cipa assay include testing the effects of mild stress, electroconvulsive therapy, and the potential for use in the treatment of Parkinson’s disease.

In studies to test for safety and efficacy, researchers have examined the response of cipa-treated mice to a variety of physical and emotional stressors, as well as to different types of drugs. Mice were exposed to four types of drugs (dietary restriction, dietary restriction with a protein-rich diet, anti-seizure drugs, and pentoxifylline) in dosages designed to simulate the physiological response of stress. Surprisingly, they showed no behavioral changes in response to stress. Interestingly, despite increasing body temperature, they showed no change in metabolic rate. These results suggest that cipa increases the activity of oxygen-sensitive, heat-induced myocardium, but does not alter the metabolic rate or cause changes in body temperature.

How Is CIPA Assay Assessed?

Cipa assay¬† is now being evaluated in clinical trials for use in patients with arrhythmias due to various diseases such as coronary artery disease, cardiac failure, peripheral arterial disease, congenital heart disease, and Parkinson’s disease. To date, cipa assay is being evaluated according to two methodologies: pharmacological and non-pharmacological. Pharmacologically, it is being evaluated in different phase I and II clinical trials to treat patients with atrial fibrillation, coronary spasm, ventricular tachycardia, and atrial biopsy. In non-pharmacologically, the drug is being evaluated in phase III trials to treat patients with ventricular tachycardia, mitral valve prolapse, atrial biopsy, cystic fibrosis, and multiple sclerosis. As of now, the results of these clinical trials are inconclusive, and the exact mode of action and concentration of cipa in the drug remains unknown.
