    Mechanisms involved in the remyelinating effect of sildenafil 

    Diaz Lucena, Daniela Del Valle (Date of defense: 2016-12-15)

    Multiple Sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system characterized by a coordinated inflammatory attack on the myelin sheaths with ensuing damage to the underlying axons. Using ...

    Mechanisms of acquired resistance to anti-EGFR therapies in squamous cell carcinoma 

    Guix Arnau, Marta (Date of defense: 2017-12-19)

    Targeted therapies against the Epidermal Growth Factor Receptor (EGFR) are useful to treat many human cancers such as non-small cell lung cancer, colorectal cancer and head and neck cancer. However, the efficacy of such ...
