The researchers first detected the marker through a study of post mortem brain samples, in which they observed an alteration in the expression of the enzyme butyrylcholinesterase (BCHE) in the brains of patients with LBD. These data indicated that there could be genetic alterations in the BCHE gene promoter, causing changes in the expression of the gene. In fact, they found four polymorphisms in the LBD promoter region that, in certain combinations, are associated with LBD. These findings, which have been patented, make it possible to determine if a patient has LBD, distinguishing it from Alzheimer's disease.
Currently, the patent is in its last stage of validation, which is being carried out in collaboration with neurologists from the Neurodegenerative Disease Unit of the Germans Trias Hospital and Bellvitge Hospital.
The licensing agreement with the Grifols company means the results can be applied, thus providing a simple, rapid, and effective procedure for diagnosing LBD in hospitals. Moreover, the marker can also be used to design clinical studies to help identify groups of patients with a more accurate diagnosis, removing, for example, LBD cases from a group of Alzheimer's patients.
