Study uncovers flu defense

Special antibodies are found that fight illness

New research has uncovered a rare antibody made by humans that fights all flu viruses. According to a Reuters report, a team at the University of Wisconsin and Theraclone Sciences, a private Seattle firm, found in tests on mice that these immune system proteins could protect against a lethal dose of influenza.

Reporting findings in the Procedures of the National Academy of Sciences, researchers contracted by Theraclone said that 60% to 80% of mice infected with deadly doses of H1N1 and H5N1 flu recovered when treated with antibodies, versus 10% of untreated animals. Theraclone used its technology to identify the antibodies, which attack a part of the flu virus that is found in most strains without many mutations.
