  • Patent number: 11129885
    Abstract: As disclosed herein, the preS antigen on infectious hepatitis B virus (HBV) particles can provide B and T ceil epitopes that promote the humoral and cellular responses and enhance the seroprotection rate by overcoming non-responsiveness to the S antigen-only vaccines. Therefore, compositions and methods are disclosed using the preS antigen to develop vaccines and immune therapies for treating or preventing hepatitis B infection, in particular, virus-like particles (VLPs) are disclosed that contain the preS antigen on its surface. These VLPs can be used alone or in combination with vaccines containing the hepatitis B surface antigen (HBsAg) to vaccinate subjects against HBV as well as to activate T ceils for adoptive T cell therapy to eradicate HBV infected hapatocytes.

  • Patent number: 10975467
    Abstract: A gas distribution plate for a chemical vapor deposition/infiltration system includes a body having a first side and a second side opposite the first side. The body may be hollow and may define an internal cavity. The gas distribution plate may also include a plurality of pass-through tubes extending through the internal cavity, a cavity inlet, and a plurality of cavity outlets. A reaction gas may be configured to flow through the plurality of pass-through tubes and a gaseous mitigation agent may be configured to flow into the internal cavity via the cavity inlet and out of the internal cavity via the plurality of cavity outlets to mix with reaction gas.
