Respiratory enzyme complex dysfunction is mechanistically involved in mitochondrial failure leading to neurodegenerative disease, but the pathway is unclear. Here, age-related differences in mitochondrial respiration were measured in both whole and permeabilized neurons from 9-month and 24-month adult rat cortex cultured in common conditions.

Tissue-specific mitochondrial HIGD1C promotes oxygen sensitivity in carotid body chemoreceptors
Mammalian carotid body arterial chemoreceptors function as an early warning system for hypoxia, triggering acute life-saving arousal and cardiorespiratory reflexes. To serve this role, carotid body glomus cells are highly sensitive to decreases in oxygen

Structural studies of T4S systems by electron microscopy [PDF]
: Type IV secretion (T4S) systems are large dynamic nanomachines that transport DNA and/or proteins through the membranes of bacteria. Analysis of T4S system architecture is an extremely challenging task taking into account their multi protein ...

Enhanced Respiratory Chain Supercomplex Formation in Response to Exercise in Human Skeletal Muscle. [PDF]
Mitochondrial dysfunction is a hallmark of multiple metabolic complications. Physical activity is known to increase mitochondrial content in skeletal muscle, counteracting age-related decline in muscle function and protecting against metabolic and ...

Brownian dynamics simulation of cytochrome c diffusion and binding with cytochrome c1 in mitochondrial crista [PDF]
Cytochrome c (Cc) protein shuttles electrons from respiratory chain complex III — from cytochrome c1 (Cc1) subunit — to complex IV during oxidative phosphorylation, in intermembrane space of mitochondria and cristae lumen.

The ‘porin-cytochrome’ model for microbe-to-mineral electron transfer [PDF]
Many species of bacteria can couple anaerobic growth to the respiratory reduction of insoluble minerals containing Fe(III) or Mn(III/IV). It has been suggested that in Shewanella species electrons cross the outer membrane to extracellular substrates via ‘
