Targeting CSF1R with selective inhibitors could help Alzheimer's

Scientists from the University of Southampton have identified the molecular system that contributes to the harmful inflammatory reaction in the brain during neurodegenerative diseases.

Allografts better survive implantation into brains of immunocompetent research mice

Researchers at the Johns Hopkins University in Baltimore, Md., and the Mossakowski Medical Research Centre in Warsaw, Poland, have found that nonself-donated cells (allografts) better survive implantation into the brains of immunocompetent research mice when the grafts are injected into the striatum (STR) of the brain rather than injected into the forceps minor (FM) region.

MPL vaccine can stimulate brain's natural defense mechanisms in people with AD

A team of researchers from Universit- Laval, CHU de Qu-bec, and pharmaceutical firm GlaxoSmithKline (GSK) has discovered a way to stimulate the brain's natural defense mechanisms in people with Alzheimer's disease.

Study investigates prolonged pathological outcomes of traumatic brain injury

Researchers from the University of South Florida and colleagues at the James A. Haley Veterans' Hospital studying the long-term consequences of traumatic brain injury using rat models, have found that, overtime, TBI results in progressive brain deterioration characterized by elevated inflammation and suppressed cell regeneration.

Researchers discover new pathway to reduce paradoxical pain

For individuals with agonizing pain, it is a cruel blow when the gold-standard medication actually causes more pain. Adults and children whose pain gets worse when treated with morphine may be closer to a solution, based on research published in the January 6 on-line edition of Nature Neuroscience.

Study examines five varieties of cells after transplantation in the CNS

When different types of cells are transplanted with the intent of having them aid in repairing central nervous system (CNS) trauma, what is the fate and function of those cells? A Belgian research team carried out research aimed at answering this question by determining how five varieties of cells - neural stem cells, mouse embryonic fibroblasts, dendritic cells, bone marrow mononuclear cells (BMMNCs) and splenocytes - functioned and survived after transplantation in the CNS.

Activated astrocytes could play a harmful role in Alzheimer's disease

A research team composed of University of Kentucky researchers has published a paper which provides the first direct evidence that activated astrocytes could play a harmful role in Alzheimer's disease.

FoxP3 gene expression identifies ALS disease progression in 80% of patients

The debilitating symptoms of amyotrophic lateral sclerosis, or ALS, appear to be increased by a lack of inflammation-reducing T cells, report scientists from the Methodist Neurological Institute in an upcoming print issue of The EMBO Molecular Medicine Journal.

Scientists define key underlying process implicated in multiple sclerosis

Scientists at the Gladstone Institutes have defined for the first time a key underlying process implicated in multiple sclerosis (MS)-a disease that causes progressive and irreversible damage to nerve cells in the brain and spinal cord. This discovery offers new hope for the millions who suffer from this debilitating disease for which there is no cure.

Microglia might play a key role in protecting brain from Alzheimer's

A new experimental study carried out in mice shows that microglia, immune cells of the brain, might play a key role in protecting the brain from Alzheimer's disease (AD).

High-resolution real-time images show how nerves may be damaged during earliest stages of MS

High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia.

Cancer-killing viruses found safe but less effective than expected

Doctors now use cancer-killing viruses to treat some patients with lethal, fast-growing brain tumors. Clinical trials show that these therapeutic viruses are safe but less effective than expected.

New genetic insight into Alzheimer’s disease

A rare mutation in the gene encoding the triggering receptor expressed on myeloid cells 2 has a potent effect on the risk for late-onset Alzheimer’s disease, two studies published in The New England Journal of Medicine suggest.

Researchers discover new gene for susceptibility to Alzheimer's disease

A large-scale international study involving French researchers from the Inserm-Institut Pasteur Lille-Universit- Lille Nord de France "Public health and molecular epidemiology of ageing-related diseases" joint research unit led by Philippe Amouyel, has just discovered a gene for susceptibility to a rare disease that causes susceptibility to a common one, Alzheimer's disease, providing evidence of the heterogeneous aetiology of Alzheimer's disease.

Researchers discover rare genetic mutation that increases risk of Alzheimer's disease

Researchers from Nottingham have played their part in the discovery of a rare genetic mutation that increases the risk of Alzheimer's disease, in a study with major implications for understanding the causes of the disease.

Blood-circulating monocytes can replace brain resident microglia

The immune system is comprised of multiple cell types each capable of specialized functions to protect the body from invading pathogens and promote tissue repair after injury. One cell type, known as monocytes, circulates throughout the organism in the blood and enters tissues to actively phagocytose (eat!) foreign cells and assist in tissue healing.

VEGF produced by NPCs plays a strong role in influencing microglial behavior

The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding adds a new dimension to our understanding of how resident stem cells and stem cell transplants may improve brain function.

LRRK2 inhibitors may provide neuroprotection for patients with Parkinson's

For decades, patients with Parkinson's disease (PD) have had the same experience. Their hands start to shake uncontrollably, their limbs become rigid and they lose their balance. Years before those movement problems set in, many begin struggling with fainting, incontinence, sexual dysfunction, anxiety and depression. Many patients are still treated with a 42-year-old drug called L-DOPA, which temporarily staves off symptoms but can itself cause heart arrhythmias, stomach bleeding and hallucinations.

Researchers identify astrocytes as new target for Alzheimer's

Alzheimer's disease is a severe neurodegenerative disease that affects 45% of people over 85 years of age. The research teams of Prof. Jin-Moo Lee at Washington University in Saint Louis, USA, and Prof. Milos Pekny at Sahlgrenska Academy in Gothenburg, Sweden, have identified astrocytes as a novel target for the development of future treatment strategies. The results have just been published in the FASEB Journal.

Scientists discover how protein deficiency may be linked to frontotemporal dementia

Using animal models, scientists at the Gladstone Institutes have discovered how a protein deficiency may be linked to frontotemporal dementia (FTD)-a form of early-onset dementia that is similar to Alzheimer's disease. These results lay the foundation for therapies that one day may benefit those who suffer from this and related diseases that wreak havoc on the brain.
