Carl Zimmer: Curing our Influenza Amnesia. By Carl Zimmer Our brains are not the only places where we can store memories.
Each time a new pathogen invades our bodies, our immune cells have an opportunity to recognize it by some feature, usually some distinctive cleft or spike of a protein on its surface. After our bodies defeat the infection, some immune cells are tasked with keeping the memory of that feature alive for years. If that same pathogen returns for a second attack, our bodies can launch a far faster counterattack. We can tutor our immune systems with vaccines. BBC Radio 4 Programmes - The End of Drug Discovery.

Half a century ago, in the drug industry's golden era, we were bestowed with countless pills to lower blood pressure, control blood sugar and get rid of infections. E-volution: Biochemistry news. Alzheimer’s drug candidate may be first to prevent disease progression A new drug candidate may be the first capable of halting the devastating mental decline of Alzheimer’s disease, based on the findings of a study published today in PLoS ONE.
When given to mice with Alzheimer’s, the drug, known as J147, improved memory and prevented brain damage caused by the disease. The new compound, developed by scientists at the Salk Institute for Biological Studies, could be tested for treatment of the disease in humans in the near future. “J147 enhances memory in both normal and Alzheimer’s mice and also protects the brain from the loss of synaptic connections,” says David Schubert, the head of Salk’s Cellular Neurobiology Laboratory, whose team developed the new drug.
