  • Publication number: 20250123269
    Abstract: A robust human cell culture model permissive to both SARS-COV-2 variants and MERS-COV is critical for assessment and validation of antivirals. Human alveolar A549 cells are regarded as a valuable model for respiratory virus infection. SARS-COV-2 uses the angiotensin converting enzyme 2 (ACE2) receptor for viral entry and the transmembrane serine protease 2 (TMPRSS2) to prime the SARS-COV-2 spike protein. By contrast, MERS-COV utilizes the dipeptidyl peptidase 4 receptor (DPP4) to enter the target cells. Three of which are negligibly expressed in A549. Disclosed herein is a generation of a robust human cell model that carries DPP4, ACE2, and TMPRSS2 receptor expressions. By transducing Dpp4 into A549-ACE2plusC3 cells (ACE2+/TMPRSS2+), the resulting cells expressing DPP4, ACE2 and TMPRSS2 (“ACE2plusC3D4”) are highly susceptible to MERS-COV and SARS-CoV-2 omicron infection. This ACE2plusC3D4 cell model can be applied for evaluation of antiviral drugs and potentially developed for high-throughput screening.

  • Patent number: 12078535
    Abstract: The invention provides a single-photon detector that includes a superconducting wire made from a high quality and uniform superconducting film with a higher critical temperature. A reflector or a multilayered reflector with high reflectivity, preferably a nitride-based distributed Bragg reflector, is provided to reflect an incident light to the superconducting wire. A surface-plasmon wavelength-selective surface may be further provided above the superconducting wire to resonantly transmits the incident light within a selective passband, making the single-photon detector operable in the ultraviolet, visible, and infrared wavelength bands. In addition, a large area of superconducting film with high level of uniformity is grown to achieve the up scaling of the single-photon detector and a single-photon detector array.
