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.

WCMC researchers devise innovative boxer-like strategy to fight multiple myeloma

Weill Cornell Medical College researchers have devised an innovative boxer-like strategy, based on the serial use of two anti-cancer drugs, to deliver a one-two punch to first weaken the defenses of multiple myeloma and then deliver the final knock-out punch to win the fight.

Researchers develop new mouse model to study supertasting

Supertasting describes the ability to strongly detect food flavors such as bitter and sweet, and it can affect a person's food preferences. For example, supertasters are often averse to green vegetables because their bitter taste is amplified. Supertasters may also prefer foods lower in sugar and fat. Approximately one out of four people is a supertaster, and a supertaster's avoidance of sweet and fatty foods may have protective cardiovascular effects.

NF-κB inhibitors can mitigate cellular damage and prevent aging-related degenerative changes

Age-associated degeneration is caused, at least in part, by accumulated cellular damage, including DNA damage, but how these types of damage drive aging remains unclear. Dr. Paul Robbins and colleagues at the University of Pittsburgh sought to address this question using a mouse model of DNA repair deficiency.

Breast milk protects against oral transmission of HIV

More than 15 percent of new HIV infections occur in children. Without treatment, only 65 percent of HIV-infected children will live until their first birthday, and fewer than half will make it to the age of two. Although breastfeeding is attributed to a significant number of these infections, most breastfed infants are not infected with HIV, despite prolonged and repeated exposure.

Laparoscopy technique lights up invisible metastases

Fluorescence laparoscopy could be the way forward for cancer surgery and staging, say researchers writing in the Archives of Surgery.

Researchers identify primary player of the biochemical bugle call

Researchers have identified the primary player of the biochemical bugle call that musters the body's defenders against viral infection.

Western-style diets may increase risk of inflammatory bowel disease

Certain saturated fats that are common in the modern Western diet can initiate a chain of events leading to complex immune disorders such as inflammatory bowel diseases (IBD) in people with a genetic predisposition, according to a study to be published early online in the journal Nature.

Alpha-myosin triggers development of autoimmunity after heart attack

After people with type 1 diabetes have a heart attack, their long-term chance of suffering even more heart damage skyrockets. But the reason has long puzzled scientists. Now researchers at Joslin Diabetes Center have identified the misstep that sparks this runaway chronic damage and a promising way to block it.

MDA5 molecule plays a critical role in fighting viral infections

Researchers have identified the primary player of the biochemical bugle call that musters the body's defenders against viral infection.

Gut microbes regulate brain levels of serotonin

UCC scientists have shown that brain levels of serotonin, the 'happy hormone' are regulated by the amount of bacteria in the gut during early life. Their research is being published today in the leading international psychiatry journal, Molecular Psychiatry.

Discovery answers why mother's immune system does not reject developing fetus as foreign tissue

Researchers at NYU School of Medicine have made an important discovery that partially answers the long-standing question of why a mother's immune system does not reject a developing fetus as foreign tissue.

Study packs powerful one-two punch in the fight against heart failure

A new study in the journal Circulation packs a powerful one-two punch in the fight against heart failure. The leading blow: Identification of a unique alliance of proteins that plays a major role in the development of the disease. The second but equally powerful hit: Drugs that interfere with this axis already exist.

Tp53 genetic mutation may play an important role in prostate cancer

A team of UC Davis investigators has found that a genetic mutation may play an important role in the development of prostate cancer. The mutation of the so-called p53 (or Tp53) gene was previously implicated in late disease progression, but until now has never been shown to act as an initiating factor. The findings may open new avenues for diagnosing and treating the disease.

Study describes how seizures in people with AS could be linked to brain cell activity imbalance

New research by scientists at the University of North Carolina School of Medicine may have pinpointed an underlying cause of the seizures that affect 90 percent of people with Angelman syndrome (AS), a neurodevelopmental disorder.

Two tumor suppressor genes function to disrupt overactive EGFR signaling

Overactive epidermal growth factor receptor (EGFR) signaling has been linked to the development of cancer. Several drug therapies have been developed to treat these EGFR-associated cancers; however, many patients have developed resistance to these drugs and are therefore no longer responsive to drug treatment.

Study identifies several proteins as new therapeutic targets and biomarkers for kidney cancer

Using blood, urine and tissue analysis of a unique mouse model, a team led by UC Davis researchers has identified several proteins as diagnostic biomarkers and potential therapeutic targets for kidney cancer. Subject to follow-up validation testing, inhibition of these proteins and several related pathways holds promise as a form of therapy to slow the growth of kidney tumors.

Blocking Skp2 protein might inhibit glycolysis and treat breast cancer

HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism, scientists report in the May 25 issue of Cell.

New method can screen for bacterial genes that are expressed during meningitis

Bacterial meningitis is an infection of the meninges, the protective membrane that covers the spinal cord and brain. Children, elderly patients and immunocompromised patients are at a higher risk for the development of severe bacterial meningitis. Recently, researchers at the University of Adelaide in Australia sought to identify new vaccine targets in Streptococcus pneumoniae, which is the most common cause of bacterial meningitis in the world.

PTH boosts AMPs to fend off infection-causing microbes

Antimicrobial peptides (AMPs) are molecules produced in the skin to fend off infection-causing microbes. Vitamin D has been credited with a role in their production and in the body's overall immune response, but scientists at the University of California, San Diego School of Medicine say a hormone previously associated only with maintaining calcium homeostasis and bone health is also critical, boosting AMP expression when dietary vitamin D levels are inadequate.
