Sialic acid

Mouse studies suggest multivalent peptides made up of carbohydrate-binding modules could be used to prevent influenza virus infection. Sialic acid-interacting peptides were generated from carbohydrate-binding modules from Streptococcus pneumoniae and Vibrio cholerae sialidase, with or without an oligomerization domain from Pseudomonas aeruginosa. In a mouse model of influenza virus challenge, prophylactic intranasal delivery of a peptide seven days before challenge led to pulmonary expression of Il-1b, interferon-g (Ifng; Ifng) and tumor necrosis factor-a (Tnf-a) and enabled survival of all mice. Next steps include testing the peptides in ferret models of influenza infection and conducting toxicology studies.
