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.

LXRbeta may play a role in prevention and treatment of Parkinson's

Scientists at the University of Houston (UH) have discovered what may possibly be a key ingredient in the fight against Parkinson's disease.

Schizophrenia and the immune system: an interview with Prof Cyndi Shannon Weickert

Schizophrenia is the most disabling disease impacting youth today. It impacts 1% of the total population and typically causes withdrawal from society, loss in IQ, disordered thought and speech, hallucinations and delusions.

Schizophrenia may be linked to immune function

New Australian research shows that the brains of people with schizophrenia may be under attack by the immune system, providing the strongest evidence to date of a link between immune function and schizophrenia.

Anakinra can dramatically limit amount of brain damage in stroke patients

Scientists led by the President of The University of Manchester have demonstrated a drug which can dramatically limit the amount of brain damage in stroke patients.

Studies report on therapeutic efficacy of stem cell transplantation in animal models of ALS, SCI

Two studies published in a recent issue of Cell Medicine report on the therapeutic efficacy of stem cell transplantation in animal models of amyotrophic lateral sclerosis (ALS) and spinal cord injury (SCI).

DRCRF names 21 new Damon Runyon Fellows

The Damon Runyon Cancer Research Foundation, a non-profit organization focused on supporting innovative early career researchers, named 21 new Damon Runyon Fellows at its spring Fellowship Award Committee review.

GMCSF linked with rapid cognitive recovery in patients with cancer

Growth factors shown to cure Alzheimer's disease in a mouse model and administered to cancer patients as part of their treatment regimen were linked to significant improvements in the patients' cognitive function following stem cell transplantation, a preliminary clinical study reports.

Scientists discover how microglia detect the site of injury

Like emergency workers rushing to a disaster scene, cells called microglia speed to places where the brain has been injured, to contain the damage by 'eating up' any cellular debris and dead or dying neurons. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now discovered exactly how microglia detect the site of injury, thanks to a relay of molecular signals.

Study sheds light on role of microglia in the normal brain

Researchers have shown in mice how immune cells in the brain target and remove unused connections between brain cells during normal development. This research, supported by the National Institutes of Health, sheds light on how brain activity influences brain development, and highlights the newly found importance of the immune system in how the brain is wired, as well as how the brain forms new connections throughout life in response to change.

Brain cells prune circuits in the brain by eating away excess synapses

We’re born with our brains prewired, but as information comes in from our environment, this circuitry is updated. A study from Boston Children’s Hospital provides a new glimpse of how this happens: Brain cells known as microglia, tuned into the crosstalk between neurons, literally engulf unnecessary connections, known as synapses, and prune them away.

Nano-devices cross blood-brain barrier to deliver drug to treat cerebral palsy

A team of scientists from Johns Hopkins and elsewhere have developed nano-devices that successfully cross the brain-blood barrier and deliver a drug that tames brain-damaging inflammation in rabbits with cerebral palsy.
