A method for synthesizing influenza virus-like particles (VLPs) within a plant or a portion of a plant is provided. The method involves expression of influenza HA in plants and the purification by size exclusion chromatography. The invention is also directed towards a VLP comprising influenza HA protein and plant lipids. The invention is also directed to a nucleic acid encoding influenza HA as well as vectors. The VLPs may be used to formulate influenza vaccines, or may be used to enrich existing vaccines.

Expression of lambda antibody light chain with non-native leader sequence, wherein light chain is sequence-engineered to restore native N terminus. Immunoglobulin lambda variable domain sequence comprising N terminal deletion for expression with non-native N terminal signal peptide.

The present invention relates to a novel chimeric antigen receptor (CAR) comprising an antigen-binding fragment which binds specifically to PSMA antigen, and a method of manufacturing high-quality CAR T cell products by transfection and/or transduction of T cells therewith, which allows to effectively treat tumors in vivo alone or in combination with pharmaceutical drugs, such chemotherapies, biopharmaceutical drugs, such as antibodies, or small-molecule drugs, such as protein kinase inhibitors.

The present disclosure provides improved compositions for adoptive T cell therapies for treating, preventing, or ameliorating at least one symptom of a cancer, infectious disease, autoimmune disease, inflammatory disease, and immunodeficiency, or condition associated therewith.

Compositions for CDKL5 gene therapy are provided, as well as recombinant CDKL5 proteins. Such CDKL5 gene therapy compositions and/or recombinant CDKL5 proteins may incorporate cell-penetrating polypeptides and/or leader signal polypeptides. Also provided are methods of producing such gene therapy compositions and recombinant CDKL5 proteins, as well as pharmaceutical compositions, methods of treatment, and uses of the gene therapy compositions and recombinant CDKL5 proteins.

Recombinant AAV (rAAV) vectors comprising a rAVV genome comprising a heterologous nucleic acid encoding a lysosomal protein, e.g., acid alpha-glucosidase (GAA) polypeptide, and optionally a signal peptide and/or optionally a targeting sequence, e.g., IGF2 targeting peptide, operatively linked to a liver-specific promoter (LSP), enabling the GAA polypeptide to be secreted from the liver and targeted to the lysosomes. Particular embodiments relate to a recombinant AAV (rAAV) vector encoding an alpha-glucosidase (GAA) polypeptide, having a liver secretory signal peptide and a IGF2 targeting peptide that binds human cation-independent mannose-6-phosphate receptor (CI-MPR) or to the IGF2 receptor, permitting proper subcellular localization of the GAA polypeptide to lysosomes. Also encompassed are cells, and methods to treat a lysosomal disease, for example, a glycogen storage disease type II (GSD II) disease and/or Pompe Disease with the rAAV vector.

Provided is an antibody, which is capable of specifically binding to a B-cell maturation antigen (BCMA). The provided BCMA antibody is capable of specifically binding to an extracellular fragment of the BCMA and has excellent affinity and specificity; and the antibody is a functional antibody and has the activity blocking binding of the BCMA with its ligand APRIL. Immune cells constructed based on the antibody has an excellent specific killing function for a BCMA-positive tumor cell.

The accuracy of immunoassay using a latex reagent is improved in a high CRP concentration range. Provided are C-reactive proteins generated by genetic recombination, 55% or more of the C-reactive proteins having a pyroglutamylated N-terminal.

Nucleic acids encoding fusion proteins that contain an unwanted antigen and a leader sequence for cell secretion are described. Also described are expression cassettes, vectors, cells, and cell lines containing the nucleic acids, as well as methods of using the nucleic acids to treat autoimmune, allergic and other diseases and disorders, such as multiple sclerosis.
