A University of California, San Diego-led team from the Alzheimer’s Disease Neuroimaging Initiative has reported that in long-term imaging studies, objective subtle cognitive deficits (obj-SCD) preceded amyloid deposition in longitudinal imaging studies.
How organisms age, and what determines their lifespan, is one of the basic questions of biology. It is also a major area of biopharmaceutical interest. Partly, this is because most people want to delay shuffling off this mortal coil for as long as possible.
Researchers at the University of Pittsburgh have discovered that intravenous (I.V.) delivery of the Bacille Calmette-Guérin (BCG) vaccine sharply improved its ability to provoke a protective T-cell response in the lungs.
The natural immune system has two lines of defense that complement each other. In response to an infection, a rapid but fairly unspecific and short-lived response by the innate immune system is followed by the precisely targeted attack of the B and T cells of the adaptive immune system, followed by immune memory that can last a lifetime
Genome sequencing is enabling new insights into the genetic aspects of health and disease that have touched just about every aspect in biomedicine. It is also, like the “skin”-colored crayons of yore, disproportionately focused on the Caucasian segment of the population. And that is a loss for everyone.

In the Dec. 20, 2019, issue of Science, Stefan Kaufmann, who is the founding director of the Max Planck Institute for Infection Biology, and his colleagues report that the immune system could calibrate its response to Pseudomonas aeruginosa by monitoring the bacterial quorum sensing chatter.
