New therapeutic targets for neurodegenerative diseases

nder certain conditions, i.e. sensory symptoms, motor symptoms, etc. and that can be induced in these animals. And they are examining if these substances that have proved to be interesting with the in vitro cells are also efficacious in these experimental models of the diseases.

Moreover, over the past few years they have had the opportunity to study samples of brains of patients who have died of some neurodegenerative illness, such as, for example, multiple sclerosis. The illnesses leaves a mark in these samples and, although the brain has been at a terminal stage of the illness, they can investigate to see if there are signs of alterations to the molecules similar to those observed in the experiments, both with cells and with the animals. In this way it can be determined if the molecular targets discovered experimentally are relevant or not to the neurodegenerative processes and, if they are, develop pharmaceutical medicines that can neutralise these processes or the elements that enable them to progress, the goal being to halt the process of death.

In collaboration with neurologists they have also been able to access biological samples of patients who have given their consent and donated them to research. Biological samples such as, fundamentally, blood, given that changes in blood plasma that may indicate alterations at the brain level can be identified.

In search of biological samples

All this is a dynamic process that enables clues to be found and which are, in some cases, relevant for developing pharmaceutical drugs that can halt, or at least slow down, the course of a neurodegenerative illness. Apart from finding these molecules or targets that interact with pharmaceutical medicines, in order to stop the process of progressive deterioration, substances that favour the survival of the neurones and oligodendrocytes are also sought; substances such as, for example, antioxidants, given that, in many of
