Vaccine developed at Rockefeller University boosts natural killer T cells in patients with cancer

A new vaccine designed at The Rockefeller University boosted a type of fast-responding immune system cell called the natural killer T (NKT) cell in patients with advanced cancer. The study surprised researchers by revealing the ability of these NKT cells to spur other, slower-responding immune cells to go to work. More »

Jeffrey Friedman, discoverer of leptin, receives Gairdner, Passano awards

Rockefeller University’s Jeffrey M. Friedman, M.D., Ph.D., a molecular geneticist whose discovery of the hormone leptin and its role in regulating body weight has changed our understanding of the causes of human obesity, has received two prestigious awards for this work: the Gairdner Foundation International Award and the Passano Foundation Award.

Rockefeller University researchers are changing the face of addiction treatment

People addicted to heroin, alcohol and other drugs of abuse often fail to stay clean because they won’t go to or won’t stay in treatment. Reporting in the January issue of the Journal of Substance Abuse Treatment, Scott Kellogg, Ph.D., and Mary Jeanne Kreek, M.D., at The Rockefeller University, and colleagues at the New York City Health and Hospitals Corporation (HHC) and at Johns Hopkins University, show that a treatment approach called contingency management improves patients’ motivation to stay in treatment and increases their therapeutic progress.

“Blinding” an insect’s sense of smell may be the best repellent

Scientists have found that a single gene is responsible for the sense of smell in fruit flies, malaria mosquitoes, medfly and corn earworm moth. This information may provide a starting point for future designs of pesticides and disease-controlling insect repellents. More »

Despite causes of lupus proving complex, scientists get a new lead on potential treatment

Scientists at The Rockefeller University have determined that the autoimmune disease lupus results from a combination of genetics that likely varies from person to person, and that a common “gatekeeper” gene called FCR?IIB is critical to the prevention of this devastating disease. More »

Rockefeller researchers identify new role for key protein that regulates separation of DNA in dividing cells

Rockefeller University scientists have revealed a new function of a key component of the mechanism that cells use to accurately separate chromosomes when they divide. Disruptions in this process can cause diseases such as cancer. More »

Blocking alcohol’s impact on brain cells

Rockefeller University scientists, in experiments with mice, have discovered a protein that regulates the seizures induced by ethanol withdrawal. The protein, called tissue plasminogen activator, or tPA, is the same factor that dissolves the blood clots that can trigger heart attacks and strokes. More »

RU mourns loss of Maclyn McCarty, scientist responsible for “pivotal discovery of 20th-century biology”

On Jan. 3, 2005, Rockefeller University President Paul Nurse informed the campus community about the death of Maclyn McCarty, one of the three Rockefeller scientists who in 1944 proved that DNA is the chemical basis for heredity. More »


Novel cellular pathway increases sensitivity of body’s immune detectives

In the Dec. 9 issue of Scientists at Rockefeller University report the discovery of a previously unknown pathway that boosts the ability of helper T cells to “motivate” killer T cells in detecting and attacking dangerous cells. The finding may help scientists to create a more effective immune response against disease and tumor formation. More »

Many ways to learn one song

Of all the world’s animals, only humans, some kinds of birds and perhaps some porpoises and whales learn the sounds they use to communicate with each other through a process of listening, imitation and practice. For the rest, including nonhuman primates, these sounds develop normally in the absence of external models. Now Rockefeller University scientists have found that zebra finches, songbirds native to Australia, use infant-like strategies to learn their song.

“Crucial evolutionary link”: Molecular sculptor may have molded simple ancient bacterial cells into modern, highly structured cells

A team of researchers led by Rockefeller University’s Michael P. Rout, Ph.D., have discovered a possible crucial evolutionary link between the simple cells that make up bacteria and the more complex cells that comprise animal and plant cells, including those of humans. More »

Cellular Two Step

Following the often-quoted advice of Yogi Berra — “You can observe a lot by just watching” — Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part “step” led by a structure within the cell called the centrosome. Once the centrosome, the key organizing point for the cell’s internal skeleton, moves forward, the cell nucleus follows. The Rockefeller scientists produced time-lapse movies that show nerve cell migration in unprecedented clarity and detail. More »

DNA barcodes find four new bird species

The task of identifying Earth’s estimated 10 million species has daunted biologists for centuries – fewer than two million have been named. Using a technique called DNA barcoding, researchers at Rockefeller University and two Canadian institutions have uncovered four new species of North American birds. The findings are reported in the September 28 issue of Public Library of Science (PLoS) Biology. More »

Essential smell gene may prove key to new insect repellents

Insects navigate by smell to find food, mates and — in the case of disease-spreading mosquitoes — humans to bite. Researchers at Rockefeller University report in the September 2 issue of Neuron that insects’ ability to detect odors depends on a single gene. Fruit flies lacking the gene, known as Or83b, cannot smell. More »
