Discovery points to a new path toward a universal flu vaccine

Flu vaccines can be something of a shot in the dark. Not only must they be given yearly, there’s no guarantee the strains against which they protect will be the ones circulating once the season arrives. New research by Rockefeller University scientists and their colleagues suggests it may be poss...

Lifelong learning is made possible by recycling of histones, study says

Neurons are a limited commodity; each of us goes through life with essentially the same set we had at birth. But these cells, whose electrical signals drive our thoughts, perceptions, and actions, are anything but static. They change and adapt in response to experience throughout our lifetimes, a...

Sequential immunizations could be the key to HIV vaccine

The secret to preventing HIV infection lies within the human immune system, but the more-than-25-year search has so far failed to yield a vaccine capable of training the body to neutralize the ever-changing virus. New research from The Rockefeller University, and collaborating institutions, sugge...

Research reveals key interaction that opens the channel into the cell’s nucleus

Cells have devised many structures for transporting molecular cargo across their protective borders, but the nuclear pore complex, with its flower-like, eight-fold symmetry, stands out. Monstrously large by cellular standards, as well as versatile, this elaborate portal controls access to and exi...

Research shows how antibodies produce vaccine-like effect against tumors

The problem with traditional cancer treatments is that their effects don’t always last:  Stop the therapy and the disease may return. That’s why antibody therapy — which not only kills tumors, but also appears to train the body’s own defenses to recognize them — has such promise. New rese...

Fragments of tRNA suggest a novel mechanism for cancer progression

For years, scientists have been puzzled by the presence of short stretches of genetic material floating inside a variety of cells, ranging from bacteria to mammals, including humans. These fragments are pieces of the genetic instructions cells use to make proteins, but are too short a length to s...

Rockefeller scientists resolve long-standing debate over how many bacteria fight off invaders

Every inch of our body, inside and out, is oozing with bacteria. In fact, the human body carries 10 times the number of bacterial cells as human cells. Many are our friends, helping us digest food and fight off infections, for instance. But much about these abundant organisms, upon which our life...

Odd histone helps suppress jumping genes in stem cells, study says

A family of proteins known as histones provides support and structure to DNA, but for years, scientists have been puzzling over occasional outliers among these histones, which appear to exist for specific, but often mysterious reasons. Now, researchers have uncovered a new purpose for one such hi...

Research on the genetic roots of a blood disorder illustrates the challenges in parsing genetic data

Accumulating data, even genetic data, is easy. Understanding the meaning of those data can be more of a challenge. As genetic testing becomes increasingly popular, more and more patients and physicians are faced with tough questions: Does a particular genetic variation translate into a predisposi...

In first human study, new antibody therapy shows promise in suppressing HIV infection

In the first results to emerge from HIV patient trials of a new generation of so-called broadly neutralizing antibodies, Rockefeller University researchers have found the experimental therapy can dramatically reduce the amount of virus present in a patient’s blood. The work, reported this week in...
