text: Under physiological conditions the brain, via the purine salvage pathway,
reuses the preformed purine bases hypoxanthine, derived from ATP degradation,
and adenine (Ade), derived from polyamine synthesis, to restore its ATP pool.
However, the massive degradation of ATP during ischemia, although providing valuable
neuroprotective adenosine, results in the accumulation and loss of diffusible
purine metabolites and thereby leads to a protracted reduction in the post-ischemic
ATP pool size. In vivo, this may both limit the ability to deploy ATP-dependent
reparative mechanisms and reduce the subsequent availability of adenosine, whilst
in brain slices results in tissue with substantially lower levels of ATP than
in vivo. In the present review, we describe the mechanisms by which brain tissue
replenishes its ATP, how this can be improved with the clinically tolerated chemicals
D-ribose and adenine, and the functional, and potential therapeutic, implications
of doing so.

text: Glutamate is the major excitatory neurotransmitter in the mammalian central
nervous system and gates non-selective cation channels. The origins of glutamate
receptors are not well understood as they differ structurally and functionally
from simple bacterial ligand-gated ion channels. Here we report the discovery
of an ionotropic glutamate receptor that combines the typical eukaryotic domain
architecture with the 'TXVGYG' signature sequence of the selectivity filter found
in K+ channels. This receptor exhibits functional properties intermediate between
bacterial and eukaryotic glutamate-gated ion channels, suggesting a link in the
evolution of ionotropic glutamate receptors.
