Experiments carried out in vivo with WSN (H0N1) and FPV (Hav1N1) strains of influenza virus have shown the presence of phosphorylated virus-induced polypeptides. Notably it was interesting the behaviour of the non-structural NS1, NP nucleoprotein and membrane M viral components whose phosphorylation was different among the cellular hosts tested. In in vitro experiments we were able to demonstrate a protein-kinase-activity in purified virions. The similarities and differences found in vivo and in vitro systems are discussed taking into consideration the fact that viral replicative cycle is closely dependent from the cellular host and the pattern of influenza virus infection is unique between different hosts.

UI	MeSH Term	Description	Entries
D009975	Orthomyxoviridae	A family of RNA viruses causing INFLUENZA and other respiratory diseases. Orthomyxoviridae includes INFLUENZAVIRUS A; INFLUENZAVIRUS B; INFLUENZAVIRUS C; INFLUENZAVIRUS D; ISAVIRUS; and THOGOTOVIRUS.

D010455	Peptides	Members of the class of compounds composed of AMINO ACIDS joined together by peptide bonds between adjacent amino acids into linear, branched or cyclical structures. OLIGOPEPTIDES are composed of approximately 2-12 amino acids. Polypeptides are composed of approximately 13 or more amino acids. PROTEINS are considered to be larger versions of peptides that can form into complex structures such as ENZYMES and RECEPTORS.	Peptide,Polypeptide,Polypeptides
