Survivors of 1918 flu pandemic protected with a lifetime immunity to virus
New research has discovered that infection and natural exposure to the 1918 influenza virus made survivors immune to the disease for the remaining of their lives. Antibodies produced by cells isolated from these survivors served as an effective therapy to protect mice from the highly lethal 1918 infection. The study entitled Neutralizing antibodies derived from the B cells of 1918 influenza pandemic survivors, was released for advanced online publication by the journal Nature. Researchers at Mount Sinai School of Medicine's Department of Microbiology contributed to the research findings. An estimated 50 million people were killed by the 1918 flu pandemic worldwide.

Weizmann Institute scientists develop a new approach to treating autoimmune disease
In autoimmune diseases, the immune system turns against the body's own tissues and organs, wreaking havoc and destruction for no apparent reason. Partly because the origins of these diseases are so obscure, no effective treatment exists, and the suffering they inflict is enormous. Now Weizmann Institute scientists have developed a method that in the future may make it possible to treat autoimmune diseases effectively without necessarily knowing their exact cause. Their approach is equivalent to sending a police force to suppress a riot without seeking out the individuals who instigated the unrest.

Vaccine/antibody therapy effective, milder side effects in melanoma and ovarian cancer
BOSTON--One of the shortcomings of a therapy that uses millions of identical antibodies to boost the immune system's attack on cancer cells is that many patients whose tumors recede in response to the treatment also experience serious inflammatory problems, such as severe diarrhea and rashes. In a new study, a team led by Dana-Farber Cancer Institute researchers shows that giving periodic infusions of such monoclonal antibodies to patients who have received a widely used cancer vaccine unleashes a strong immune response to tumors, with less-harsh side effects.

Study proposes new theory of how viruses may contribute to cancer
PITTSBURGH, Oct. 23 – A new study suggests that viruses may contribute to cancer by causing excessive death to normal cells while promoting the growth of surviving cells with cancerous traits. Viruses may act as forces of natural selection by wiping out normal cells that support the replication of viruses and leaving behind those cells that have acquired defects in their circuitry. When this process is repeated over and over, cancer can develop say study authors, led by Preet M. Chaudhary, M.D., Ph.D., professor of medicine at the University of Pittsburgh School of Medicine. Their findings are published by Public Library of Science in the Oct. 24 issue of PLoS ONE.
