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

by  /  22 October 2019

Drug after drug has failed in clinical trials for fragile X syndrome. A new study provides an explanation — a decrease in the drugs’ effectiveness over time — and points to a new strategy that could circumvent this problem.
