Immune cells may underlie anxiety in autistic people

by  /  16 December 2019

Some cases of anxiety, which often accompanies autism, may stem from a faulty immune system, a new study suggests — but some experts are skeptical.

Mitochondrion, coloured transmission electron micrograph (TEM). Mitochondria are a type of organelle found in the cytoplasm of eukaryotic cells. They oxidise sugars and fats to produce energy in a process called respiration. A mitochondrion has two membranes, a smooth outer membrane and a folded inner membrane. The folds of the inner membrane are called cristae, and it is here that the chemical reactions to produce energy take place. Magnification: x62,800 when printed at 10 centimetres wide.

Leaky mitochondria may play central role in fragile X syndrome

Faulty mitochondria may fuel features of fragile X syndrome

by  /  14 March 2019

Problems with the minute ‘factories’ that yield energy for cells — the mitochondria — may contribute to learning problems and other traits of fragile X syndrome.
