    Regulació transcripcional dels receptors d'adenosina en les malalties neurodegeneratives 

    Pérez Buira, Sandra (Date of defense: 2010-02-26)

    Els receptors d'adenosina són receptors acoblats a proteïna G classificats en A1, A2A, A2B i A3 en funció del grau d'afinitat pel seu agonista endogen, l'adenosina. Els receptors A1 i A3 interaccionen amb l'adenilat ciclasa ...

    Role of Guanylate Cyclase Activating Proteins in photoreceptor cells of the retina in health and disease 

    López del Hoyo, Natalia (Date of defense: 2014-03-14)

    In the last two decades, it has been done a thoroughly research about the role of Guanylate Cyclase Activating Proteins (GCAPs) in photoreceptor cells of the retina as activity regulators of Retinal Guanylate Cyclase ...

    La senyalització purinèrgica al sistema reproductor. Paper de les ecto-nucleotidases a l’endometri no tumoral i amb adenocarcinoma 

    Aliagas Marín, Elisabeth (Date of defense: 2014-10-08)

    Els nucleòtids extracel·lulars, com l’ATP, i els nucleòsids que deriven de la seva hidròlisi, com l’adenosina, estan àmpliament distribuïts en tots els òrgans i sistemes animals i estan considerats com a potents molècules ...

    Streptococcus pneumoniae, resistance and disease in adults in the era of conjugate vaccines 

    Càmara Mas, Jordi (Date of defense: 2021-07-27)

    [eng] Streptococcus pneumoniae is an important human pathogen, being one of the main etiological agents of serious infectious diseases such as pneumonia or meningitis and other less serious like otitis media. S. pneumoniae ...

    Study on the Connexion 32 and its role in the release of ATP. 

    Grandes Vilaclara, Mª Eugenia (Date of defense: 2008-06-18)

    The aim of this 4 year long work was to study the Connexin32 (Cx32), a protein that forms hemichannels anchored in the plasma membrane. Two hemichannels of adjacent cells form a gap junction. Mutations in Cx32 have been ...

    Synaptic transmission in autaptic circuits: presynaptic homeostatic plasticity and microtubule dynamics 

    Velasco Domínguez, Cecilia (Date of defense: 2022-04-22)

    Synapses are the contact sites where the transfer of information from the presynaptic to the postsynaptic site occurs. Correct processing of information requires that synapses continuously adapt their properties to an ...

    Synthetic Polymyxin-based Peptides Against Multidrug Resistant Bacteria: A Therapeutic Option 

    Rudilla Mateo, Héctor (Date of defense: 2019-01-18)

    Pseudomonas aeruginosa and Staphylococcus aureus are nosocomial opportunistic pathogens causing a wide variety of both acute and chronic infections, such as pneumonia, bacteraemia, and urinary tract infections. Immunocompromised ...

    Unveiling novel components of the protein complex responsible for cGMP synthesis in retinal photoreceptors: role in cell physiology and disease 

    López Begines, Santiago (Date of defense: 2016-11-18)

    In photoreceptor cells of the retina, light triggers a protein G-mediated enzymatic cascade that leads to hydrolysis of cGMP. The drop in cGMP levels causes the closure of cGMP-channel at the plasma membrane, decreasing ...

    Verrugas plantares: caracterización de los virus causales y aplicación del láser 1064 nm a su tratamiento 

    Planell Mas, Elena de (Date of defense: 2016-12-20)

    INTRODUCCIÓN: Las verrugas plantares están provocadas por el virus del papilloma humano (VPH). Se han descrito diferentes genotipos asociados a estas lesiones si bien existen pocos estudios centrados exclusivamente en ...

    Vías de señalización en enfermedades priónicas 

    Rodríguez Fernández, Agustí (Date of defense: 2007-10-04)

    Las enfermedades priónicas, también conocidas como EETs (Encefalopatías Espongiformes Transmisibles), son un grupo de enfermedades neurodegenerativas fatales que, debido a su transmisibilidad potencial han tenido un gran ...
