Families considering PGD to avoid passing on disease genes face obstacles such as high cost and invasive procedures.
Several thousand people have used preimplantation genetic diagnosis to avoid passing on pathogenic mutations to their babies, but many families with a history of Alzheimer’s or related diseases remain unaware of this option.
Some macrophages use their dying breath to emit a distress signal that could spell trouble for their neighbors.
