Stem Cells Can Be Distinguished on the Basis of Sugar Residues: A new study suggests

 A new study at Bochum let to the development of an antibody that allows them to distinguish the numerous types of stem cells in the nervous system better than before.

"In order to use stem cells for therapeutic purposes, it is important to be able to distinguish between the different types," explained Eva Hennen of the RUB Department of Cell Morphology and Molecular Neurobiology (Faculty of Biology and Biotechnology). The antibody 5750 recognises a specific sugar residue on the cell surface, which is called LewisX. The research group led by Prof. Dr. Andreas Faissner has now been able to use LewisX for the first time to separate different types of stem cells. The researchers report on their results in the Journal of Biological Chemistry.

Unexpected sugar diversity

Antibodies that recognise the LewisX sugar residue are used routinely to identify so-called neural stem cells from which the various cells of the nervous system originate. Prof. Faissner's team has now shown that the designation "LewisX" does not just cover a single sugar motif, but a whole range of different sugar residues. Different types of neural stem cells are equipped with individual combinations of LewisX sugar residues on their cell surface. The new Bochum antibody 5750 recognises a different LewisX sugar residue to the antibodies previously used. "This sugar diversity could also be interesting for cancer diagnosis" Prof. Faissner explained, "because LewisX sugars have also been detected on tumour cells."

New Research: Genes Determine Donor Kidney Survival

A new study by researchers at Wake Forest Baptist Medical Center sheds light on what causes certain kidneys to do better than others after being transplanted.

"It's been long observed that kidneys taken from some black donors just don't last as long as those taken from non-black donors, and the reason for that has not been known," said Barry I. Freedman, M.D., John H. Felts III Professor and senior investigator. "This study reveals that the genetic profile of the donor has a marked affect on graft survival after transplantation. We now know that these organs aren't failing because they came from black donors, but rather because they came from individuals with two copies of a specific recessive gene."

The study appears in the May issue of the American Journal of Transplantation.

Freedman and co-researchers at Wake Forest Baptist examined 12 years' worth of medical records dating back to 1998, looking for all patients who received a kidney transplant from a black deceased donor whose genetic information had been recorded. The search yielded 106 black donors -- from whom one or both kidneys were transplanted -- for a total of 136 donated kidneys.

The researchers identified that kidneys from donors who had specific coding changes in a gene called apolipoprotein L1 (APOL1) did not last as long after transplant as those from donors without these changes. These coding changes in the APOL1 gene that affect kidney transplant function are found in about 10 to 12 percent of black individuals. Recent studies, led by Freedman and his colleagues, have shown that these genetic changes are associated with an increased risk of kidney disease, which prompted researchers to investigate the role of these changes in transplant success.

"In looking at the records and follow-up of the recipients of these organs, we accounted for all the usual factors that are known to contribute to more rapid loss of kidney function after transplant," said Freedman, chief of the section on nephrology. "What we found was that the kidney disease-causing risk variants in APOL1 were the strongest predictor of graft loss after transplant. The effect of having two copies of this gene was stronger than the impact of genetic matching between donor and recipient, the amount of time the organ was out of the body, and the antibody levels. APOL1 dwarfed all these other factors known to affect survival."

If the finding is confirmed by other researchers, it has the potential to dramatically improve outcomes for both the individuals undergoing kidney transplantation and those considering kidney donation, Freedman said. It could revolutionize donor selection criteria, allowing transplant physicians the ability to identify kidneys that are likely to function for shorter periods of time. In addition, this screening tool has the potential to help doctors protect potential donors who may be at risk of developing kidney disease down the road.

Certain Heart Medications Better Taken At Night

A new study to be published in the May 17, 2011 issue of the Journal of the American College of Cardiology suggests that ACE inhibitors, a class of cardiac drugs, may be more efficacious when administered at night. ACE inhibitors are used to treat high blood pressure and heart disease, especially in people who have sustained a heart attack. They reduce the deleterious post-heart attack remodeling of heart tissue which usually occurs at night. By studying mice, the researchers found that those who were given the medication at night demonstrated better heart function and preservation of normal heart size than mice that were given the medication in the morning. The study calls to attention the need for more studies on the best times to administer cardiac drugs, since evidence shows that heart function runs on a cyclic pattern. For example, it is well known that the risk of heart attack is dramatically increased in the mornings for a variety of reasons. Therefore, giving medications to anticipate this would be more beneficial than taking a medication after one awakens.

glutamate receptors

Glutamate neurotransmission plays an important role in a number of physiologic and pathophysiologic processes. Activation of glutamate receptors occurs in pathways involved in pain, neurotoxicity and memory formation.

There are big expectations in the neuropharmacology field about the possible clinical applications of novel agents acting on these receptors. Some of the conditions that might benefit from future glutamatergic drugs include: hyperalgesia, stroke, epilepsy and schizophrenia.

This article overviews the structure and physiology of glutamate receptors.

Outline:

• Classification
  • Ionotropic glutamate receptors
    • NMDA receptors
    • AMPA receptors
    • Kainate receptors
  • Metabotropic receptors

Structure and characteristics

Glutamate receptors are divided into two subgroups: ionotropic (ligand-gated ion channels) and metabotropic (G protein-coupled receptors).

Ionotropic glutamate receptors

These receptors act as cation-selective channels, when activated they allow the flow of Na⁺ , K⁺ and Ca²⁺.

Ionotropic glutamate receptors can be subdivided into three subtypes, according to their activation by selective agonists such as NMDA, AMPA and kainate.

NMDA receptors

NMDA receptors are ligand-gated ion channels, with a primary glutamate-binding site and an allosteric glycine-binding site.These receptors consist of multisubunit oligomeric transmembrane complexes. NDMA receptor subunits include:

• NR1
• NR2A
• NR2B
• NR2C
• NR2D

Smith, S. Diabetic Retinopathy and the NMDA Receptor, Drug News Perspect 2002, 15(4): 226

Three events need to occur simultaneously in order to activate NMDA receptors: binding of glutamate and glycine (which acts as cotransmitter) and membrane depolarization. Under resting conditions,  Mg²⁺ ions block the channel pore in the resting membrane. When NMDA receptors are activated, Mg²⁺ ions are removed from their location, allowing the influx of Ca⁺² ions.

AMPA receptors

AMPA (alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid) receptors are constituted of four subunits:

• GluR1
• GluR2
• GluR3
• GluR4

These receptors regulate fast excitatory postsynaptic depolarization at glutamatergic synapses. AMPA receptors are located in the CNS, specially in the hippocampus and cerebral cortex.

Kainate receptors

Kainate receptors are expressed throughout the CNS, particularly in the hyppocampus and cerebellum where they play a role in both pre- and postsynaptic neurotransmission.

Five kainate receptor subunits have been identified:

• GluR5
• GluR6
• GluR7
• KA1
• KA2

According to recent findings, kainate receptors may be relevant in pain neurotransmission.

Metabotropic glutamate receptors

Metabotropic glutamate receptors (mGluR) are seven transmembrane-spanning proteins that exert their actions through G protein signalling cascades.

There are eight subtypes of metabotropic glutamate receptors, which are organized into three separate groups (I, II and III).

Recent findings suggest that groups II and III might be located presynaptically, where they function as autoreceptors to block glutamate release. Autoreceptors act as "detectors" of glutamate activity in the synaptic cleft. When ligands activate group II and III mGluRs glutamate release may be reduced. Therefore, activation of presynaptic group II and III mGLURs may inhibit glutamatergic excitatory neurotransmission.

Group I metabotropic glutamate receptors may be located postsynaptically, where they hypothetically enhance excitatory glutamatergic neurotransmission.
