Glycolysis-mediated control of blood-brain barrier development and function.

The blood-brain barrier (BBB) consists of differentiated cells integrating in one ensemble to control transport processes between the central nervous system (CNS) and peripheral blood. Molecular organization of BBB affects the extracellular content and cell metabolism in the CNS. Developmental aspects of BBB attract much attention in recent years, and barriergenesis is currently recognized as a very important and complex mechanism of CNS development and maturation.

An investigation of the association of the H558R polymorphism of the SCN5A gene with idiopathic cardiac conduction disorders.

Aim: The aim of this study was to investigate the predictive value of the rs1805124 polymorphism of the SCN5A gene with regard to idiopathic cardiac conduction disorders.

Results: The AG genotype frequency was significantly higher in patients with an atrioventricular block (61,2%±6,0%) compared with healthy control subjects (34,8%±2,3%), p<0.0001.

The glial perspective of autism spectrum disorders.

The aetiology of autism spectrum disorders remains unclear although a growing number of associated genetic abnormalities and environmental factors have been discovered in recent decades. These advancements coincided with a remarkable increase in the comprehension of physiological functions and pathological potential of neuroglia in the central nervous system that led to a notion of fundamental contribution of glial cells into multiple neuropathologies, including neuropsychiatric and developmental disorders. Growing evidence indicates a role for deregulation of astroglial control over homeostasis and plastic potential of neural networks as well as microglial malfunction and neuroinflammatory response in the brains of autistic patients.
