    Abstract: An illumination module includes a light source configured to emit an illumination light beam, a reflective light valve disposed on a path of the illumination light beam and configured to form a plurality of pixels, a lens, and an image sensing module. Each pixel is adapted to be switched between a first state and a second state. The pixels in the first state among the pixels are configured to reflect the illumination light beam into an effective light beam. The pixels in the second state among the pixels are configured to reflect the illumination light beam into a complementary light beam. The lens is disposed on a path of the effective light beam and configured to project the effective light beam to an area to be illuminated. The image sensing module is disposed on a path of a complementary light beam from the reflective light valve and configured to sense the complementary light beam.

  • 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.
