La quercetina, un flavonoide presente in natura, possiede diverse proprietà farmacologiche, tra cui attività antiossidanti, antinfiammatorie, antivirali, antibatteriche, antifungine, cardioprotettive, neuroprotettive, antidiabetiche e antitumorali. I suoi effetti antiossidanti derivano dalla capacità di eliminare i radicali liberi e di potenziare i meccanismi di difesa cellulare, mentre le sue proprietà antinfiammatorie comportano l’inibizione di NF-κB, dell’attivazione dell’inflammasoma e della produzione di citochine, rendendola un potenziale trattamento per l’infiammazione cronica, le tempeste di citochine indotte da COVID-19 e l’ARDS.La quercetina presenta un’attività antimicrobica ad ampio spettro, che colpisce batteri, funghi e virus disgregando le membrane microbiche, inibendo la sintesi degli acidi nucleici e prevenendo la formazione di biofilm. Ha dimostrato un’efficacia antivirale contro la SARS-CoV-2 inibendo la replicazione virale, l’attività della proteasi e aumentando la protezione cellulare mediata da NRF2. Inoltre, le sue proprietà cardioprotettive e neuroprotettive lo rendono utile per l’ipertensione e le malattie neurodegenerative, mentre i suoi effetti antitumorali riguardano l’inibizione della crescita tumorale, l’induzione dell’apoptosi e il potenziamento dell’efficacia della chemioterapia.

  • Viral Replication Complexes
    Viruses are obligate intracellular parasites that need to co-opt a living cell’s machinery for replication. At the heart of the viral replication machinery are the nucleic acid polymerases, which are responsible for efficiently copying the viral genome. This process must often be coordinated with other viral processes, including protein translation and viral packaging. The poly...
  • Advances in Flavivirus Research
    The flaviviruses are composed almost entirely of arthropod-borne viruses, a subset of which are responsible for millions of cases of human disease each year. Among these viruses are dengue virus—a scourge throughout the tropical regions of Asia and the Americas; yellow fever virus—the “original” hemorrhagic fever virus; and the recently emerged Zika virus. While the flaviviruse...

    Lesley J. Rogers / Lesley JRogers
    This edited book brings together research reports on the asymmetry of brain function in various species, including humans, dogs, birds, lizards and bees. As shown in a wide range of species, and, as we now know, not solely in humans, the left and right sides of the brain process information in different ways and control different responses or patterns of behaviour. Since this d...

    Joëlle Roche
    The epithelial-to-mesenchymal transition (EMT) is a highly dynamic process with multiple transitional states, by which epithelial cells can convert into a mesenchymal phenotype. This process involves loss of cellular adhesion and cellular polarity, and an improvement in migratory and invasive properties. It occurs during normal embryonic development, tissue regeneration, organ ...
