Leprosy bacteria lead to new understanding of nerve damage and cell proliferation

For nervous system cells, specialization is a one-way street. But as is often the case in biology, the rules have exceptions. Glial cells — nervous system cells that form a highly specialized insulating sheath called myelin that surrounds nerve fibers — under certain conditions can “de-differe...

Expression of 'Blimp1' gene leads to the discovery of cells responsible for skin's sebaceous gland

Mice may not get zits, but they do have oily skin. This week, new research on mice from Rockefeller University shows how the cells responsible for oil production develop, and uncovers clues about how stem cells renew and differentiate. The research focuses on the skin’s sebaceous gland, which i...

Rockefeller researchers receive Gates Foundation grant for HIV vaccine research

The Bill & Melinda Gates Foundation has announced 16 grants totaling $287 million to create an international network of highly collaborative research consortia focused on accelerating the pace of HIV vaccine development. The grants will support a range of innovative approaches for designing an ef...

Scientists ID a single sugar that allows antibodies to fight inflammation

For years, researchers have struggled to understand how IVIG works. Its ability to treat autoimmune diseases seemed to be an apparent contradiction. Intravenous immunoglobulin (IVIG) is a complex mixture of IgG antibodies made from human plasma that contains the pooled antibodies from thousands o...

Evidence of rapid evolution is found at the tips of chromosomes

In terms of their telomeres, mice are more complicated than humans. That’s the finding from a recent Rockefeller University study, which shows that mice have two proteins working together to do the job of a single protein in human cells. The findings, published recently in Cell, suggest that the ...

Nine Rockefeller labs to receive Stem Cell Initiative grants

The Tri-Institutional Stem Cell Initiative, comprising three leading New York City biomedical research institutions — Memorial Sloan-Kettering Cancer Center, The Rockefeller University and Weill Medical College of Cornell University — has announced the first wave of stem cell research projects t...

Human stem cells can contribute to a developing mouse embryo, despite evolutionary differences

Using a newly derived line of human embryonic stem cells, Rockefeller University researchers have coaxed human cells to grow in mouse tissue. Ali Brivanlou, an embryologist who specializes in studying how the nervous system develops, and his colleagues demonstrated that despite the evolutionary d...

Sound investment: A new mathematical method provides a better way to analyze noise

Humans have 200 million light receptors in their eyes, 10 to 20 million receptors devoted to smell, but only 8,000 dedicated to sound. Yet despite this miniscule number, the auditory system is the fastest of the five senses. Researchers credit this discrepancy to a series of lightning-fast calcul...

Insights into the spliceosome suggest new explanations for generating biological complexity

While politicians debate whether evolution occurs, scientists are busy debating how it occurs. Now, new research from Rockefeller's Magda Konarska suggests that there are more ways than previously thought to achieve the impressive complexity characteristic of humans. Many organisms -- including h...
