Abstract:
The present invention relates to the mRNA vaccine of coronavirus spike protein with deletion of glycosites in the receptor binding domain (RBD), the subunit 1 (S1) domain, or the subunit 2 (S2) domain, or a combination thereof. The vaccine elicits broadly protective immune responses coronavirus and variants thereof.
Abstract:
Immunogenic compositions comprising partially glycosylated viral glycoproteins for use as vaccines against viruses are provided. Vaccines formulated using mono-, di-, or tri-glycosylated viral surface glycoproteins and polypeptides provide potent and broad protection against viruses, even across strains. Pharmaceutical compositions comprising monoglycosylated hemagglutinin polypeptides and vaccines generated therefrom and methods of their use for prophylaxis or treatment of viral infections are disclosed. Methods and compositions are disclosed for influenza virus HA, NA and M2, RSV proteins F, G and SH, Dengue virus glycoproteins M or E, hepatitis C virus glycoprotein E1 or E2 and HIV glycoproteins gp120 and gp41.
Abstract:
The present disclosure relates to a chimeric influenza virus hemagglutinin (HA) polypeptide, comprising one or more stem domain sequence, each having at least 60% homology with a stem domain consensus sequence of H1 subtype HA (H1 HA) and/or H5 subtype HA (H5 HA), fused with one or more globular head domain sequence, each having at least 60% homology with a globular head domain consensus sequence of H1 subtype HA (H1 HA) or H5 subtype HA (H5 HA).
Abstract:
The present disclosure relates to compositions and methods of use comprising antibodies or binding fragments thereof further comprising universal Fc glycoforms.

Abstract:
The present disclosure relates to an antibody or antigen-binding fragment thereof that specifically binds to a spike protein of SARS-COV-2. The present disclosure also relates to a pharmaceutical composition, a method for treating and/or preventing diseases and/or disorders caused by a coronavirus in a subject in need thereof, and a method for detecting a coronavirus in a sample.
Abstract:
Disclosed herein is a method for treating or preventing a coronavirus infection, which comprises administering to a subject in need thereof an effective amount of a composition comprising Flt3 receptor interacting lectin (FRIL) from Lablab purpureus. Also disclosed is a pharmaceutical composition comprising a pharmaceutically acceptable excipient, a Lablab purpureus FRIL, and an additional therapeutic agent.
Abstract:
The present disclosure relates to glycoproteins, particularly monoclonal antibodies, comprising a glycoengineered Fc region, wherein said Fc region comprises an optimized N-glycan having the structure of Sia2(α2-6)Gal2GlcNAc2Man3GlcNAc2. The glycoengineered Fc region binds FcγRIIA or FcγRIIIA with a greater affinity, relative to comparable monoclonal antibodies comprising the wild-type Fc region. The monoclonal antibodies of the invention are particularly useful in preventing, treating, or ameliorating one or more symptoms associated with a disease, disorder, or infection where an enhanced efficacy of effector cell function (e.g., ADCC) mediated by FcγR is desired, e.g., cancer, autoimmune, infectious disease, and in enhancing the therapeutic efficacy of therapeutic antibodies the effect of which is mediated by ADCC.
