The cancer drug paclitaxel just got more effective. For the first time, researchers from the University of North Carolina at Chapel Hill have packaged it in containers derived from a patient’s own immune system, protecting the drug from being destroyed by the body’s own defenses and bringing the entire payload to the tumor. “That means we can use 50 times less of the drug and still get the same results,” said A/Prof Elena Batrakova, Ph.D...

Read MoreMany brain disorders involve the death of neurons, or nerve cells, but how these neurons die is not well understood. A new study describes how the activation of normally protective immune responses causes nerve cells to die and identifies the protein responsible, providing a potential target for therapeutic intervention.
Researchers from NIH’s National Institute of Allergy and Infectious Diseases (NIAID) studied the effect of immune system proteins: toll-like receptors on neurons...
Read MoreMore than a century ago, scientists demonstrated that sleep supports the retention of memories of facts and events. Later studies have shown that slow-wave sleep, often referred to as deep sleep, is important for transforming fragile, recently formed memories into stable, long-term memories. Now, it has been shown deep sleep may also strengthen immunological memories of previously encountered pathogens.
Studies in humans have shown that long-term increases in memory T cells are associated with deep slow-wave sleep on the nights after vaccination. Taken together, the findings support the view that slow-wave sleep contributes to the formation of long-term memories of abstract, generalized information, which leads to adaptive behavioral and immunological responses...
