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)

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)

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)

'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... view more (2006-12-04)

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... view more (2004-08-23)

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... 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... view more (2003-11-11)

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)

Epilepsy-induced brain cell damage prevented in the laboratory
For some epilepsy patients, the side effects of epilepsy can be as troubling as the seizures. One pressing concern is the cognitive impairment seizures often inflict, which potentially includes memory loss, slowed reactions and reduced attention spans.   view more (2007-10-30)

Immune system pathway identified to fight allergens, asthma
For the first time, researchers from the University of Pittsburgh School of Medicine have identified genetic components of dendritic cells that are key to asthma and allergy-related immune response malfunction.   view more (2008-05-08)

Antibiotics may not be enough to stop recurrent gastric lymphoma caused by Helicobacter pylori
Research led by Dr. Anne Mueller at Stanford University School of Medicine demonstrates that successful eradication of Helicobacter may not prevent future aggressive gastric lymphoma since resting B cells are left behind.   view more (2005-08-25)

USC researchers discover novel way to develop tumor vaccines
Researchers at the University of Southern California (USC) have uncovered a new way to develop more effective tumor vaccines by turning off the suppression function of regulatory T cells.   view more (2008-03-03)

Novel method to create personalized immunotherapy treatments
Argos Therapeutics and Université de Montréal today announced the presentation of new information on Argos'process for developing dendritic cell-based immunotherapies for HIV.   view more (2008-08-06)

Personalized immunotherapy to fight HIV/AIDS
For a long time, the main obstacle to creating an AIDS vaccine has been the high genetic variability of the HIV virus. Dr. Jean-Pierre Routy and his team from the Research Institute of the McGill University Health Centre (MUHC), in collaboration with Dr. Rafick Sékaly from the... view more (2008-08-18)

What makes an axon an axon?
Inside every axon is a dendrite waiting to get out. Hedstrom et al. converted mature axons into dendrites by banishing a protein crucial for neuron development.   view more (2008-11-10)

T cells activated to fight HIV basis for dendritic cell therapeutic vaccine
Having their immune system cells go through a laboratory version of boot camp may help patients win their battle against HIV.   view more (2006-08-14)
