Novel cellular pathway increases sensitivity of body's immune detectives

Rockefeller University researchers shed light on how T cells are activated, providing insight for the design of more effective vaccines and immunotherapies The human body uses many mechanisms to fight disease, but perhaps the most important cells in the immune system are the T cells. Helper and k...

Many ways to learn one song

Baby songbirds and human infants learn sounds in similar ways 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...

"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. This molecular sculptor may...

Cellular Two Step

Time-lapse movies show brain cells move like a two-stroke engine 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" le...

DNA barcodes find four new bird species

Short stretch of DNA sequence fast, accurate method for identifying 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...

Essential smell gene may prove key to new insect repellents

Repellents that block gene might help fight malaria and other infectious diseases 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 insect...

Silencing human gene through new science of epigenetics; Gene associated with human development—and cancer

For the first time, scientists have shown how the activity of a gene associated with normal human development, as well as the occurrence of cancer and several other diseases, is repressed epigenetically — by modifying not the DNA code of a gene, but instead the spool-like histone proteins around...

Single isolated mouse skin cell can generate into variety of epidermal tissues

Sheets of stem cells, created in the lab, grow hair, skin and oil glands on hairless mice Researchers at the Howard Hughes Medical Institute at The Rockefeller University have isolated stem cells from the skin of a mouse, and showed, for the first time, that an individual stem cell can renew itse...
