Dr. John Aitchison

The NCDIR’s Dr. John Aitchison has been awarded the Lung Association’s  COVID-19 Respiratory Virus Research Award.

Dr. Aitchison’s  project is geared to further research on the use of inhaled nanobodies to complement current COVID-19 vaccines and drugs to serve critically ill patients, act as a preventative treatment and retain effectiveness new variants of the virus

“Here in Washington, we face continued lung health challenges from COVID-19 every day. This is in addition to our region’s lung health being threatened by poor air quality due to increased wildfire smoke, continued cigarette and e-cigarette use and more. Today, more than 917,000 people in our state are living with chronic lung disease…We are excited for John Aitchison to join the American Lung Association Research Team to help improve lung health here in Washington and across the nation.”  – Season Oltmann, Executive Director of the American Lung Association

NCDIR Scientists awarded New York State Biodefense Commercialization Fund

April 11, 2022|

Prof. Michael Rout

Prof. Michael Rout (Rockefeller University) and his co-investigators in the Chait lab and Aitchison Labs are recipients of the New York State Biodefense Commercialization Fund. The Fund is a new initiative started by Gov. Kathy Hochul which aims to support researchers in the development of new technologies to combat infectious disease threats.

Research Spotlight: New comprehensive map of the portal to the cell’s nucleus

January 3, 2022|

The nuclear pore complex (NPC) is a shrewd gatekeeper. Dotting the surface of the nucleus, these protein complexes comprise the sole portals in and out of the cell’s command center, granting passage only to select molecules. NPCs are essential to the cell’s survival, and even minute abnormalities in their components may contribute to a host of diseases, from heart conditions to cancer to Alzheimer’s.

Now, a new study published in Cell provides a comprehensive, three-dimensional structure of the nuclear pore complexes of yeast cells. “This is a big breakthrough for us,” says Rockefeller’s Michael P. Rout. “Our model reveals novel features of the various parts of the pore’s structure, giving us new insights into how this sophisticated gateway evolved, maintains its architecture, and functions as a transport machine. A better understanding of the basic biology of the NPC will hopefully lead to new insights in its role in human disease.”

Rout and colleagues, including Rockefeller’s Brian T. Chait and coworkers at Boston University School of Medicine, the University of California San Diego, University of California San Francisco, and Baylor College of Medicine, used a multipronged approach to capture a complete picture of the NPC, combining cryo-electron microscopy and other cutting-edge imaging techniques in order to maximize resolution and coverage.

They identified 28 flexible connectors that tie the inner ring of the complex together and likely aid in rapid assembly and disassembly of the NPC during cell division. Crucially they also addressed a question that has stumped the field for many decades, namely: are all NPCs in a single nucleus essentially the same? They have found that the answer is a definitive “no”: at least three very distinct variants can coexist within a single yeast cell, each potentially specializing in different functions such as the transport of different proteins or RNA, say Rout and Chait.

The findings are the latest in a decades-old quest to understand how molecules enter and exit the cell nucleus, and follow from a 2018 study in which Rout and Chait identified the 552 nucleoporins of the yeast pore complex and determined how they fit together.
