Human immunodeficiency virus (HIV) envelope proteins having mutations that stabilize the trimeric form of the envelope protein are provided. The HIV envelope proteins have certain amino acid substitutions at specified positions in the envelope protein sequence. The HIV envelope proteins described herein have an improved percentage of trimer formation and/or an improved trimer yield as compared to an HIV envelope protein that does not have one or more of the indicated amino acid substitutions. Also provided are nucleic acid molecules and vectors encoding the HIV envelope proteins, as well as compositions containing the HIV envelope proteins, nucleic acid, and vectors.

Trimer stabilizing HIV envelope protein mutations

Human immunodeficiency virus (HIV) envelope proteins having specified mutations that stabilize the trimeric form of the envelope protein are provided. The HIV envelope proteins described herein have an improved percentage of trimer formation and/or an improved trimer yield. Also provided are particles displaying the HIV envelope proteins, nucleic acid molecules and vectors encoding the HIV envelope proteins, as well as compositions containing the HIV envelope proteins, particles, nucleic acid, or vectors.

Filovirus glycoprotein mutations that stabilize the trimeric form of the glycoprotein are provided. The Filovirus glycoproteins have certain amino acid substitutions at specified positions in the glycoprotein sequence. The Filovirus glycoproteins described herein have an improved percentage of trimer formation and/or an improved trimer yield as compared to a Filovirus glycoprotein that does not have one or more of the indicated amino acid substitutions. Also provided are nucleic acid molecules and vectors encoding the Filovirus glycoproteins, as well as compositions containing the Filovirus glycoproteins, nucleic acid, and vectors.

Stabilized Filovirus glycoprotein trimers

The invention relates to immunogenic compositions and vaccines containing a coronavirus (e.g., Wuhan coronavirus (2019-nCoV; also referred to as SARS-CoV-2)) protein or a polynucleotide encoding a coronavirus (e.g., Wuhan coronavirus (2019-nCoV; SARS-CoV-2)) protein and uses thereof. The invention also provides methods of treating and/or preventing a coronavirus (e.g., Wuhan coronavirus (2019-nCoV; SARS-CoV-2)) infection by administering an immunogenic composition or vaccine to a subject (e.g., a human). The invention also provides methods of detecting and/or monitoring a protective anti-coronavirus (e.g., Wuhan coronavirus (2019-nCoV; SARS-CoV-2)) antibody response (e.g., anti-coronavirus antibody response, e.g., anti-2019-nCoV antibody response, e.g., anti-Spike antibody response, e.g., anti-Spike neutralizing antibody response). The present invention relates to isolated nucleic and/or recombinant nucleic acid encoding a coronavirus S protein, in particular a SARS-CoV-2 S protein, and to the coronavirus S proteins, as well as to the use of the nucleic acids and/or proteins thereof in vaccines.
