New understanding of basic units of memory
A molecular "recycling plant" permits nerve cells in the brain to carry out two seemingly contradictory functions - changeable enough to record new experiences, yet permanent enough to maintain these memories over time. view more (2007-09-20)
Short-term stress can affect learning and memory
Short-term stress lasting as little as a few hours can impair brain-cell communication in areas associated with learning and memory, University of California, Irvine researchers have found. view more (2008-03-12)
Long-term changes in experience cause neurons to sprout new long-lasting connections
Howard Hughes Medical Institute researchers have discovered that neurons in the brains of mice sprout robust new connections when the animals are adjusting to new experiences. view more (2006-06-22)
UCR researchers propose minocycline as a promising drug for patients with Fragile X syndrome
A UC Riverside-led team of biomedical scientists has found that a readily available drug called minocycline, used widely to treat acne and skin infections, can be used to treat Fragile X syndrome, the most common inherited cause of mental impairment and the most common cause of autism. view more (2008-10-03)
Traffic jam in brain causes schizophrenia symptoms
Schizophrenia waits silently until a seemingly normal child becomes a teenager or young adult. Then it swoops down and derails a young life. view more (2009-08-11)
Tiny RNA molecules fine-tune the brain's synapses
Non-coding regions of the genome - those that don't code for proteins - are now known to include important elements that regulate gene activity. view more (2006-01-19)
MIT corrects inherited retardation, autism in mice
Researchers at MIT's Picower Institute for Learning and Memory have corrected key symptoms of mental retardation and autism in mice. view more (2007-12-20)
A new step towards an AIDS vaccine
Progressive disease after HIV infection is inversely correlated with the presence of plasmacytoid dendritic cells (pDCs), a subset of the dendritic cell family and the major producers of type 1 interferon in the body. view more (2005-10-14)
Proteins anchor memories in our brain
A University of Utah study suggests that memories are held in our brains because certain proteins serve as anchors, holding other proteins in place to strengthen synapses, which are connections between nerve cells. view more (2006-11-22)
'Super' enzyme may lead way to better tumor vaccines
A "super" form of the enzyme Akt1 could provide the key to boosting the effect of tumor vaccines by extending the lives of dendritic cells, the immune-system master switches that promote the response of T-cells, which attack tumors, said researchers at Baylor College of Medicine in a report that appears in the "advance online... view more...

Why you remember names and ski slopes
When you meet your boss's husband, Harvey, at the office holiday party, then bump into him an hour later over the onion dip, will you remember his name? view more (2007-11-26)
Rac 1 and 2, two proteins essential to triggering of the immune response
The dendritic cells act as the body's sentries, standing guard around the clock. As soon as they detect a potential enemy, they alert the T cells, whose role is to defend the body. At the Institut Curie, CNRS researchers in an Inserm laboratory have filmed the encounter of dendritic cells and T cells. They have shown that this "rendez-vous",... view more... (2004-08-23)
Protein linked to mental retardation controls synapse maturation, plasticity, CSHL team finds
A team of neuroscientists at Cold Spring Harbor Laboratory (CSHL) has demonstrated the mechanism by which a signaling protein found throughout the brain controls the maturation and strength of excitatory synapses, the tiny gaps across which the majority of neurons communicate. view more (2009-06-02)
Better vaccines with special cells
More effective vaccines will be developed as a result of research at the University of Dundee which is harnessing the skills of special cells in the body`s immune response process. The Medical Research Council has awarded Professor Colin Watts and his colleagues £1.2 million to fund work on key cells in our immune system called dendritic... view more... (2002-02-25)
Parasite lipids against asthma or diabetes
Dutch research has demonstrated that lipids from the parasite schistosoma can inhibit human immune responses. This property makes the lipids interesting for a possible new treatment of diseases such as asthma and diabetes where the immune system responds inappropriately. During her doctoral research, Desiree van der Kleij discovered that lipids... view more... (2003-11-11)
New origin found for a critical immune response
An immune system response that is critical to the first stages of fighting off viruses and harmful bacteria comes from an entirely different direction than most scientists had thought, according to a finding by researchers at the Duke University Medical Center. view more (2009-03-02)
Stopping a receptor called 'nogo' boosts the synapses
New findings about a protein called the nogo receptor are offering fresh ways to think about keeping the brain sharp. view more (2008-03-19)
Malaria parasite impairs key immune system cells
Plasmodium, the parasite responsible for malaria, impairs the ability of key cells of the immune system to trigger an efficient immune response. view more (2006-04-12)
Immune cells promote blood vessel formation in mouse endometriosis
A discovery in mice of immune cells that promote the formation of new blood vessels could lead to new treatments for endometriosis, a painful condition associated with infertility that affects up to 15 percent of women of reproductive age. view more (2007-10-19)
MIT researchers reverse symptoms in mice of leading inherited cause of mental retardation
Researchers at the Picower Institute for Learning and Memory at MIT have, for the first time, reversed symptoms of mental retardation and autism in mice. view more (2007-06-26)
