Dr. Noelia López-Sánchez graduated in Biology at the Madrid Universidad Complutense and she gained her doctorate in Molecular and Cellular Biology at the Madrid Universidad Autónoma. Since the very beginning of her professional career, the main aim of her research has been the study of both the development and the degeneration of the central nervous system. Initially, she wrote a minor thesis describing the cerebral toxicity of heavy metals at the Madrid Universidad Complutense and subsequently, she drafted her doctoral thesis at the Instituto Cajal of the del Consejo Superior de Investigaciones Científicas (Council for Scientific Investigation) (CSIC). At the Toledo Paraplegia Hospital she carried out studies aimed at the repair and regeneration of medullar lesions with the help of biomaterials. On her return to the Instituto Cajal, she joined Dr. Frade’s group, where her work has concentrated on the description and study of tetraploid neurons in the CNS in developing subjects and adults of higher vertebrates. The improvement of the techniques and protocols that she has been able to develop during this period has been, and continues to be, a key element in order to be able to characterise and analyse the aforementioned neurons. The discovery of the existence of tetraploid neurons in humans, as well as their possible implication in the pathology of Alzheimer’s disease, was the grounds for the creation of the company Tetraneuron S.L., for which she has been working since its creation. Currently, her efforts are aimed at the development of therapies for Alzheimer’s disease, as well as for the possible early diagnosis of the disease.
