A lot changes in a child’s body over the course of development, and not all changes occur linearly: gene expression can fluctuate, and organs can perform different functions on the way to their final purpose in the body. Here are some of the key deve

The initiating cause of Alzheimer’s disease is still unknown. However, from our studies it’s clear that many types of neuronal damage—­­from traumatic brain injury, to epilepsy, infection, or genetic predisposition—­can activate brain immune cells—microglia and astrocytes-- promoting them to produce IL-1 and S100 inflammatory cytokines.
