Xue lab at the CDI publishes groundbreaking insights into memory T cells in Nature Immunology

Xue lab at the CDI publishes groundbreaking insights into memory T cells in Nature Immunology
2024-01-18
(Press-News.org) The Xue Lab at the Hackensack Meridian Center for Discovery and Innovation (CDI) has made another breakthrough in better understanding, and potentially modulating, the immune system to fight diseases.

 

The insights into a specific protein and how it regulates the training and efficacy of central memory T cells are published by Hai-Hui (Howard) Xue, a member of the CDI, in the journal Nature Immunology.

 

The immunological implications could produce better vaccines and cancer treatments in the future, according to the Xue lab, which is also part of the Institute for Immunologic Intervention (3i) at the CDI.

 

The molecular focus is on the transducin-like enhancer (Tle) family of proteins. Specifically, their inquiry homed in on Tle3, and how it exactly functions in the training of T cells. 

 

Their observations in preclinical models, both ex- and in-vivo, showed consistently that Tle3 functioned as a mediator and regulator of complex interactions which allow antigen-experiencedT cells to be specialized in response to foreign threats - and thereby become central memory T cells that are more efficacious in protection. 

 

By releasing the “brakes” of Tle3’s regulation, Xue and the team were able to accelerate the formation of central memory T cells and hence supercharge immune response. 

 

The implications could allow future manipulation of the immune system - by releasing the brakes and unleashing T cells to faster and more forcefully respond to threats, including both infectious disease and cancer, according to the paper.

 

“In sum, Tle3 uses dual functions in gene regulation guard (effector memory) T cell lineage fidelity, and releasing the brake mediated by Tle3 facilitates the formation of (central memory) T cells with better durability and more robust recall capacity,” conclude the authors. 

 

The paper follows a series of central memory T cell publications which were published in Nature Immunology, the Proceedings of the National Academy of Sciences, and other journals. The latest, from December 2023, focused on another protein called CTCF.

Don’t look back: The aftermath of a distressing event is more memorable than the lead-up, study suggests
2024-01-18
Halfway through a true crime podcast, a morning commuter jerks the wheel to narrowly avoid a collision. When discussing the podcast with a coworker later that day, the driver can easily recall the details of the episode’s second half but retains only a blurry recollection of how it began. A new study from psychologists at the Beckman Institute for Advanced Science and Technology suggests that we remember the moments immediately following a distressing episode more sharply than the moments leading up to it. Clarifying the relationship ...

FIFA World Cup ends with win for Argentina and COVID-19, new research finds

FIFA World Cup ends with win for Argentina and COVID-19, new research finds
2024-01-18
TORONTO, Jan. 18, 2024 – The 2022 FIFA World Cup ended with a tight win for Argentina over France on penalties, but it was also a triumph for SARS-CoV-2 with a significant jump in the number of cases, some of which York University researchers say could have been prevented. New research published today and led by York used the 2022 FIFA World Cup as a case study to help determine the best ways to mitigate virus spread and hospitalizations at mass gatherings in the future. A technique was used ...

New PET/CT technique accurately diagnoses adrenal gland disorder, informs personalized treatment plans

New PET/CT technique accurately diagnoses adrenal gland disorder, informs personalized treatment plans
2024-01-18
Reston, VA—A novel imaging approach, 68Ga-pentixafor PET/CT, has been shown to accurately identify sub-types of primary aldosteronism (an adrenal gland disorder), outperforming traditional methods for diagnosis. Reported in the January issue of The Journal of Nuclear Medicine, this detailed imaging technique provides a clearer picture of the adrenal glands, helping doctors decide more confidently whether surgery is the right option for patients. Primary aldosteronism is an endocrine disorder that occurs when the adrenal glands produce too much of the hormone aldosterone, frequently ...

A window into plant evolution: The unusual genetic journey of lycophytes

2024-01-18
An international team of researchers has uncovered a remarkable genetic phenomenon in lycophytes, which are similar to ferns and among the oldest land plants. Their study, recently published in the journal PNAS, reveals that these plants have maintained a consistent genetic structure for over 350 million years, a significant deviation from the norm in plant genetics. "The exceptionally slow pace of genomic evolution sets these plants apart," said Dr. Fay-Wei Li, a professor at the Boyce Thompson Institute and a senior author of the study. ...

Climate change linked to spread of diarrheal illness

2024-01-18
Temperature, day length and humidity have been found to be linked to the increased spread of a diarrhoeal illness a new study from the University of Surrey reveals. The findings could help predict further outbreaks of the illness, potentially leading to better preparedness within health services. During this unique study, researchers led by Dr Giovanni Lo Iacono, investigated the impact of weather on the transmission of campylobacteriosis, a bacterial infection which can cause diarrhoea and stomach pains. According to the World Health Organisation, Campylobacter infections are the most common causes of human bacterial gastroenteritis in the world. Infections are generally ...

Injectable agents could improve liquid biopsy for cancer detection and monitoring

2024-01-18
Scientists have developed two agents, made of therapeutic nanoparticles and antibodies, that could be given to patients shortly before a blood draw to allow physicians to better detect tumor DNA in blood using a technology called liquid biopsy. Liquid biopsies promise to transform how cancers are diagnosed, monitored, and treated by detecting DNA that tumors shed into the blood. But the body presents a significant challenge. Immune cells in the liver and DNA-degrading enzymes in blood remove circulating tumor DNA from the bloodstream within minutes, making this DNA difficult to capture and detect in a blood test. To overcome this, a team from the Broad Institute of MIT and Harvard ...

Researchers improve blood tests’ ability to detect and monitor cancer

2024-01-18
CAMBRIDGE, MA -- Tumors constantly shed DNA from dying cells, which briefly circulates in the patient’s bloodstream before it is quickly broken down. Many companies have created blood tests that can pick out this tumor DNA, potentially helping doctors diagnose or monitor cancer or choose a treatment. The amount of tumor DNA circulating at any given time, however, is extremely small, so it has been challenging to develop tests sensitive enough to pick up that tiny signal. A team of researchers from MIT and the Broad Institute of MIT and Harvard has now come up with a way to significantly boost that signal, by temporarily slowing the clearance of tumor DNA circulating in the bloodstream. The ...
