摘要:
Provided herein are compositions and methods for treating and preventing lung disease. In particular, provided herein are SP-A peptides and uses thereof in the treatment and prevention of lung disease (e.g., asthma or COPD). The compositions may comprise peptides having an amino acid sequence of Ac-WGKEQCVE(Nle)(Pego3)-Hdc (SEQ ID NO: 24) The peptide compositions may also be used to treat COVID-19.
摘要:
Peptides suitable for preparation of lung surfactants are described. Examples include one that include a first fragment comprising the amino acid sequence of XWLXRALIKRIQAZI (SEQ ID NO: 1) or a first amino acid sequence having at least 90% sequence identity to SEQ ID NO: 1 and a second fragment comprising the amino acid sequence of RZLPQLVXRLVLRXS (SEQ ID NO: 2) or a second amino acid sequence having at least 90% sequence identity to SEQ ID NO: 2, wherein X is any amino acid but at least one amino acid at the X positions is not cysteine, or Z is any amino acid but at least one amino acid at the Z positions is not methionine. Surfactants that contain such peptides, and related compositions, methods of preparing and using the compositions are also described.
摘要:
Reconstituted surfactants comprising a lipid carrier, a polypeptide analog of the native surfactant protein SP-C, and a polypeptide analog of the native surfactant protein SP-B are useful for the treatment and/or prophylaxis of RDS and other respiratory disorders.
摘要:
The invention relates to a polyribonucleotide with a sequence that codes a protein or protein fragment, wherein the polyribonucleotide comprises a combination of unmodified and modified nucleotides, wherein 5 to 50% of the uridine nucleotides and 5 to 50% of the cytidin nucleotides are modified uridine nucleotides or modified cytidin nucleotides.
摘要:
Surfactant protein D (SP-D) is a 43-kDa member of the collectin family of collagenous lectin domain-containing proteins that is expressed in epithelial cells of the lung. Described herein are methods and compositions for the treatment of disorders associated with lung injury, including methods and compositions for the treatment of bronchopulmonary disorder (BPD) using recombinant human surfactant protein D and surfactant formulations.
摘要:
A novel alpha-1 antitrypsin variant, a method of preparing the same, and use thereof are provided. The alpha-1 antitrypsin variant has excellent stability in the body and maintains an inhibitory effect on elastase activities because the blood half-life (t1/2) and the area under blood drug concentration vs. time curve (AUC) are remarkably increased by adding an N-glycosylation site in animal cells through amino acid mutation between 1st and 25th positions of the N-terminus of alpha-1 antitrypsin. Therefore, the alpha-1 antitrypsin variant can be useful in preventing or treating alpha-1 antitrypsin deficiency.
摘要:
Lyophilized pulmonary surfactants having an increased specific surface area and porosity are described. A method of making lyophilized pulmonary surfactants is described.
摘要:
