New Human Brain Cell Discovered

Researchers have identified a new brain cell thought to be unique to humans found in part of the brain linked to consciousness. Much of the human brain remains a mystery to scientists. It’s the reason we sit at the top of the food chain, but the question of what makes our brains different to other animals remains a somewhat elusive one for neuroscientists. The study published in the journal Nature Neuroscience identified a new and mysterious type of human brain cell.

HIV infection: Antibody can Block B cells from Fighting Pathogens, New Mechanism

For the first time, scientists have shown that in certain people living with HIV, a type of antibody called immunoglobulin G3 (IgG3) stops the immune system's B cells from doing their normal job of fighting pathogens. This phenomenon appears to be one way the body tries to reduce the potentially damaging effects of immune-system hyperactivity caused by the presence of HIV, according to the investigators, but in so doing, it also impairs normal immune function.
