There are two 1b amino acid switches that may be predictors of nonresponse, and may be the reason why 1b is a little tougher to clear. More than the title might infer, this approach to the study of control mechanisms has required a full exposition of metabolic pathways, and the book has become a true successor to the 1971 Ciba symposium on Strategy of the Viral Genome and Colter and Paranchych's 1966, Molecular Biology of Viruses.

These pathologic effects are manifested in clinical symptoms of relapse and disability. Although not virus-specific, interferon displays a characteristic cell specificity, being active on homologous and not on heterologous cells. interferon's exhibit anti-cancer and anti-bacterial effects. Interferon induced the formation of serum neutralizing antibodies in approximately 10-20% of treated patients. Naturally occurring proteins and glycoproteins Secreted by eukaryotoc cells in response to viral inections, tumors and other biological inducers Structurally, they are part of the helical cytokine family which are characterized by an amino acid chain that is 145-166 amino acids long The mechanism of this resistance is not yet known but, by analogy with other viral infections, it seems likely that the hepatitis C virus is an interferon inhibitor that allows the virus to replicate even in the presence of interferons. Netherlands Society of Microbiology Meeting on April 15, 1961; Published: December 1961; Mechanism of action of interferon. MECHANISM OF ACTION.

For example, both interferon-α (IFN-α) and interleukin-2 (IL-2) are administered to melanoma patients. Isaacs and Lindenmann reported in 1957 that influenza virus-infected chick cells produced a secreted factor that mediated the transfer of a virus-resistant state active against both homologous and heterologous viruses ( 180 ).
