False-colour transmission electron micrograph (TEM) of the bacterium Escherichia coli, genetically-engineered to produce quantities of human gamma interferon, appearing here as the orange mass ringed in mauve. The interferons are a group of proteins (called lymphokines) that are produced by T- lymphocytes that act to inhibit intracellular viral replication & modulate the proliferation of other cells involved in the immune response. They are believed to be effective against some infections (hepatitis), autoimmune disease (rheumatoid arthritis) & some cancers. Magnification x28, 000 at 6x7cm size.
