D-serine as a gliotransmitter and its roles in brain development and disease
The development of new techniques to study glial cells has revealed that they are active participants in the development of functional neuronal circuits. Calcium imaging studies demonstrate that glial cells actively sense and respond to neuronal activity.

Post‐translational regulation of human D‐3‐phosphoglycerate dehydrogenase in Alzheimer's disease
Abstract Emerging evidence suggests that sex‐specific differences in L‐serine (L‐Ser) metabolism play a key role in Alzheimer's disease (AD). While disruptions in amino acid balance are well known, recent findings point to a dimorphic regulation of the serine biosynthetic pathway.

N-methyl-D-aspartic acid receptor (NMDAr) activation requires the presence of D-serine, synthesized from L-serine by a pyridoxal 5′-phosphate-dependent serine racemase (SR). D-serine levels can be lowered by inhibiting the racemization of L-serine.

Paenarthrobacter are specialists in degrading the fungicide iprodione. We showed that this trait has evolved through gene duplication of ipaH and ddaH genes, being in the core genome of paenarthrobacters, and further genetic optimisation, with different strains being at different evolution stages depending on their prior exposure to iprodione ...

Ischemic acute kidney injury perturbs homeostasis of serine enantiomers in the body fluid in mice: early detection of renal dysfunction using the ratio of serine enantiomers. [PDF]
The imbalance of blood and urine amino acids in renal failure has been studied mostly without chiral separation. Although a few reports have shown the presence of D-serine, an enantiomer of L-serine, in the serum of patients with severe renal failure, it

Abstract figure legend AII amacrine cells are an important class of interneuron in the vertebrate retina. In addition to traditional chemical synapses these cells communicate with other neurons and with each other via electrical synapses. (A) Electrical synapse strength between AII amacrine cells was measured using dual whole‐cell patch‐clamp ...

The fundamental role of D-serine as a co-agonist at the N-methyl-D-aspartate receptor (NMDAR), mediating both physiological actions of glutamate in long term potentiation and nociception and also pathological effects mediated by excitotoxicty, are well ...

ABSTRACT Nonketotic hyperglycinemia is a severe neonatal epileptic encephalopathy caused by deficient glycine cleavage enzyme activity, for which currently no effective treatment exists. Incomplete understanding of brain biochemistry represents a major knowledge gap to develop new treatments.

Leptospira interrogans serovar Hardjo and Leptospira borgpetersenii serovar Hardjo are major bovine‐ and ovine‐adapted pathogens that differ markedly in genome content. To investigate early events during host exposure, we compared the survival of both species using an ovine peritoneal dialysis membrane chamber (DMC) model, which exposes leptospires to ...

Association Study of Serine Racemase Gene with Methamphetamine Psychosis [PDF]
Experimental studies have demonstrated that not only dopaminergic signaling but also glutamatergic/NMDA receptor signaling play indispensable roles in the development of methamphetamine psychosis. Our recent genetic studies provided evidence that genetic variants of glutamate-related genes such as DTNBP1, GLYT1, and G72, which are involved in glutamate
