Lou Gehrig's Protein Found Throughout Brain, Suggesting Effects Beyond Motor Neurons

wo years ago researchers at the University of Pennsylvania School of Medicine discovered that misfolded proteins called TDP-43 accumulated in the motor areas of the brains of patients with amyotropic lateral sclerosis (ALS), or Lou Gehrig's disease. Now, the same group has shown that TDP-43 accumulates throughout the brain, suggesting ALS has broader neurological effects than previously appreciated and treatments need to take into account more than motor neuron areas.

Key Gene For Making Motor Neurons Discovered

Simple, everyday movements require the coordination of dozens of muscles, guided by the activity of hundreds of motor neurons. Now, researchers have revealed an important step in the process that guides the early development of neurons themselves, as they establish the precise connections between the spinal cord and muscles. This knowledge will help scientists search for drugs to treat diseases that destroy motor neurons, such as amyotrophic lateral sclerosis, or Lou Gehrig's disease.

Researchers Discover Key Gene for Making Motor Neurons

Cross section of the mouse spinal cord, showing that the FoxP1 protein (red) marks the nuclei of motor neurons that innervate limb muscles. These neurons also express a retinoid synthetic enzyme RALDH2 (green) which is controlled by FoxP1 and directs later aspects of motor neuron development. Expression of FoxP1 in these neurons is essential for the activity of Hox proteins that control motor neuron diversity.

Protein Plays Jekyll And Hyde Role In Lou Gehrig's Disease

Amyotrophic lateral sclerosis (ALS), more commonly known as Lou Gehrig's disease, is a fatal neurodegenerative disease caused by the death of motor neurons in the brain and spinal cord that control muscle movements from walking and swallowing to breathing.

Robot with a Biological Brain: new research provides insights into how the brain works

(PhysOrg.com) -- A multidisciplinary team at the University of Reading has developed a robot which is controlled by a biological brain formed from cultured neurons. This cutting edge research is the first step to examine how memories manifest themselves in the brain, and how a brain stores specific pieces of data. The key aim is that eventually this will lead to a better understanding of development and of diseases and disorders which affect the brain such as Alzheimer's Disease, Parkinson's Disease, stroke and brain injury.

Neurons Control Robot

Researchers at the University of Reading, in England, have developed a robot controlled by a biological "brain." Hundreds of thousands of rat neurons communicate via a multielectrode array--a dish with over 60 two-way electrodes that transmit signals between neurons and outside electronics--to control the movement of a wheeled robot. When the neurons receive signals that the robot is nearing an object, their output moves the wheels in an attempt to avoid obstacles. The researchers, led by neuroscientists Mark Hammond, Ben Whalley, and cyberneticist Kevin Warwick, suggest that by stimulating the neurons with different signals as the robot returns to a familiar location, they will be able to study how a brain stores data. Their goal is to eventually understand memory formation and disorders, such as Alzheimer's and Parkinson's.

Crossing the blood-brain barrier with nanotechnology

(Nanowerk Spotlight) The challenge in treating most brain disorders is overcoming the difficulty of delivering therapeutic agents to specific regions of the brain by crossing the blood-brain barrier (BBB). This barrier – a tight seal of endothelial cells that lines the blood vessels in the brain – is a physiological checkpoint that selectively allows the entry of certain molecules from blood circulation into the brain. The problem for scientists is that the BBB does not differentiate what it keeps out. BBB strictly limits transport into the brain through both physical (tight junctions) and metabolic (enzymes) barriers. With very few exceptions, only nonionic and low molecular weight molecules soluble in fat clear the BBB. For instance, alcohol, caffeine, nicotine and antidepressants meet these criteria.

Robot with a biological brain

University of Reading scientists have developed a robot controlled by a biological brain formed from cultured neurons. And this is a world’s premiere. Other research teams have tried to control robots with ‘brains,’ but there was always a computer in the loop. This new project is the first one to examine ‘how memories manifest themselves in the brain, and how a brain stores specific pieces of data.’ As life expectancy is increasing in most countries, this new research could provide insights into how the brain works and help aging people. In fact, the main goal of this project is to understand better the development of diseases and disorders which affect the brain such as Alzheimer or Parkinson diseases. It’s interesting to note that this project is being led by Professor Kevin Warwick, who became famous in 1998 when a silicon

Resveratrol found to improve health, but not longevity in aging mice on standard diet

Scientists have found that the compound resveratrol slows age-related deterioration and functional decline of mice on a standard diet, but does not increase longevity when started at middle age. This study, conducted and supported in part by the National Institute on Aging (NIA), part of the National Institutes of Health, is a follow-up to 2006 findings that resveratrol improves health and longevity of overweight, aged mice. The report confirms previous results suggesting the compound, found naturally in foods like grapes and nuts, may mimic, in mice, some of the effects of dietary or calorie restriction, the most effective and reproducible way found to date to alleviate age-associated disease in mammals.

Deconstructing Green Fluorescent Protein

Green fluorescent protein (GFP) has been reassembled from two pieces, a large fragment 214 amino acids in length that is produced recombinantly (GFP 1−10) and a short synthetic peptide corresponding to the 11th stave of the β-barrel that is 16 amino acids long (synthetic GFP 11), following a system developed by Waldo and co-workers (Cabantous, S.; et al. Nat. Biotechnol. 2005, 23, 102−7) as an in vivo probe for protein association and folding. We demonstrate that the reassembled protein has identical absorption and excited-state proton transfer dynamics as a whole protein of the identical sequence. We show that the reassembled protein can be taken apart and the peptide replaced with a different synthetic peptide designed to perturb the chromophore absorption.

Rat's Brain Powers Robot

New Scientist reports on a cool, if somewhat creepy development in robotics -- scientists have used bits from a rat's brain to control a robot. The 'why' behind such a Frankenstein is to learn more about how a brain works: by studying the rat brain's reponses to controlled stimulus, the scientists hope to learn more about the internal workings of a brain, which will go a long way to understand the nature of human brain disorders such as Alzheimer's.

Quantum rods probe blood-brain barrier

(Nanowerk News) One of the chief difficulties in treating brain tumors involves getting potential tumor-killing drugs across the blood-brain barrier and into the brain. Now, researchers from a NCI Cancer Nanotechnology Platform Partnership at the University of Buffalo have used targeted quantum rods both to breach the blood-brain barrier and to study how such constructs move across this largely impermeable barrier. Paras Prasad, Ph.D., principal investigator of the SUNY-Buffalo Platform Partnership, led the research team that published results in the journal Bioconjugate Chemistry ("Bioconjugated Quantum Rods as Targeted Probes for Efficient Transmigration Across an in Vitro Blood-Brain Barrier").

Protein folding: terahertz absorption spectroscopy detects changes in protein-water network

(Nanowerk News) Water is no passive spectator of biological processes; it is an active participant. Protein folding is thus a self-organized process in which the actions of the solvent play a key role. So far, the emphasis in studies of protein folding processes has been on observation of the protein backbone and its side chains.

Brain Will Be Battlefield of the Future, Warns US

Anti-Globalism sends this except from the Guardian: "In a report commissioned by the Defense Intelligence Agency, leading scientists were asked to examine how a greater understanding of the brain over the next 20 years is likely to drive the development of new medicines and technologies. They found several areas in which progress could have a profound impact, including behaviour-altering drugs, scanners that can interpret a person's state of mind and devices capable of boosting senses such as hearing and vision. ...The report highlights one electronic technique, called transcranial direct current stimulation, which involves using electrical pulses to interfere with the firing of neurons in the brain and has been shown to delay a person's ability to tell a lie.

Life-extending Protein Can Also Have Damaging Effects On Brain Cells

Proteins widely believed to protect against aging can actually cause oxidative damage in mammalian brain cells, according to a new report in the July Cell Metabolism, a publication of Cell Press. The findings suggest that the proteins can have both proaging and protective functions, depending on the circumstances, the researchers said.
