    摘要: A multi-functional broad-spectrum antiviral and anti-inflammatory nanosystem and methods of treating, including prophylactically, coronavirus infections, such as those caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by administering such nanosystem to a patient is presented. The nanosystem may be comprised of a combination of therapeutic agents directed to the particular coronavirus encapsulated in a nanoparticle that is surface coated with a targeting moiety. For CoV-2 infections, an antiviral such as the PPAR-γ agonist leriglitazone (LG) and an siRNA targeting a conserved sequence of the virus can be encapsulated within a nanoparticle surface coated with a fatty acid such as linoleic acid, as the targeting moiety. Administration can occur intranasally prior to infection for prophylactic treatment or post-infection for treatment of the viral infection.

    摘要: An in vitro microfluidic device includes a device configured to model a blood-brain barrier. The device includes a center well in fluidic communication with each of an inlet and an outlet. Each of the center well, inlet, and outlet includes a porous membrane that separates a “blood” portion (a fluid flow portion) from a “brain” portion (a fluid containing portion). The porous membrane is seeded with endothelial cells such as the human venule endothelial cells (HUVECs) on the blood side, and with astrocytes on the brain side, to accurately model the blood-brain barrier. Fluid flows between the inlet, the center well, and the outlet to test the permeability of the porous membrane, thereby providing an accurate in vitro model of a blood-brain barrier.
