The human immune system consists of various cells circulating in blood and lymph vessels that can localize to sites of damage, injury, or infection and help in repairing damaged cells and destroying foreign or unhealthy substances. The immune system is complex, involving innate mechanisms such as inflammation and fever as well as adaptive mechanisms like […]


Neurotrophic Factors and Huntington’s Disease

Neurotrophic factors are proteins that promote the development, maintenance and survival of neurons in the brain. These factors have been shown to increase the function of nerve cells as well as protect diseased neurons from dying. There are often higher levels of neurotrophic factors in areas with local neuronal damage, meaning that neurotrophic factors might […]



Scientists once thought that the brain stopped developing after the first few years of life. They thought that connections formed between the brain’s nerve cells during an early “critical period” and then were fixed in place as we age. If connections between neurons developed only during the first few years of life, then only young […]
