Researchers identify new mechanism that teaches immune cells-in-training to spare the body’s own tissues while attacking pathogens.
Aresearch team is testing a protein block to suppress specific cells of the body’s immune system contribute to developing type 1 diabetes. If successful, the drug would diminish autoimmunity, preserving the body’s ability to naturally produce more insulin, the researchers said.
A research team led by UCLA’s Anusha Kalbasi, MD, has shown that a synthetic IL-9 receptor allows cancer-fighting T cells to do their work without the need for chemotherapy or radiation.
Detecting these T cells may lead to diagnostics to better detect heart disease—and disease severity.
If you’re wondering why after two vaccination doses and a booster shot, you still got sick from the omicron strain of the virus that causes COVID-19, one possible answer may have been found in a recent study by researchers at Johns Hopkins Medicine and the National Institute of Allergy and Infectious Diseases (NIAID) at the National Institutes of Health (NIH).
In a new study by Yale Cancer Center, researchers show stem-like T cells within certain lymph nodes could be natural cancer fighters.
New study shows CAR T cells expressing RN7SL1 can activate the body’s natural immune cells against difficult-to-treat cancers
New research conducted in monkeys reveals that T cells are not critical for the recovery of primates from acute COVID-19 infections.
A metabolic control pathway that regulates T follicular helper cells offers targets for drugs to stimulate the adaptive immune response.

Research published in Nature reveals insights into how the body maintains balance with “good” gut bacteria that allows these microbes to flourish in the intestine but keeps them out of tissues and organs where they’re not supposed to be.
A Phase II trial led by researchers at The University of Texas MD Anderson Cancer Center found that BK virus (BKV)-specific T cells from healthy donors were safe and effective as an off-the-shelf therapy for BKV-associated hemorrhagic cystitis (BKV-HC), a painful complication common after allogeneic stem cell transplants for patients with leukemia or lymphoma. The study was published today in the Journal of Clinical Oncology.

‘Tissue-resident memory T cells’, whose main function is to provide local protection against re-infection, contribute to chronic transplant rejection.
By analyzing blood samples from individuals infected with SARS-CoV-2, researchers in Singapore have begun to unpack the different responses by the body’s T cells that determine whether or not an individual develops COVID-19. The study, published today in the Journal of Experimental Medicine (JEM), suggests that clearing the virus without developing symptoms requires T cells to mount an efficient immune response that produces a careful balance of pro- and anti-inflammatory molecules.
A paper published today in Nature shows how chemicals in the areas surrounding tumors – known as the tumor microenvironment – subvert the immune system and enable cancer to evade attack. These findings suggest that an existing drug could boost cancer immunotherapy.
Scientists discovered that the molecule AIM2 is important for the proper function of regulatory T cells and plays a key role in mitigating autoimmune disease. Treg cells are a seminal population of adaptive immune cells that prevents an overzealous immune responses.
Vaccines take time to work. After getting a COVID-19 vaccine, it takes a while for the immune system to fully respond and provide protection from the virus. For the Moderna and Pfizer COVID-19 vaccines, it takes up to two weeks after the second shot to become appropriately protected.
A big question on people’s minds these days: how long does immunity to SARS-CoV-2 last following infection?
Now a research team from La Jolla Institute for Immunology (LJI), The University of Liverpool and the University of Southampton has uncovered an interesting clue. Their new study suggests that people with severe COVID-19 cases may be left with more of the protective “memory” T cells needed to fight reinfection.
Researchers at The University of Texas MD Anderson Cancer Center have discovered that a protein called NF-kappa B-inducing kinase (NIK) is essential for the shift in metabolic activity that occurs with T cell activation, making it a critical factor in regulating the anti-tumor immune response.
Melanoma is skilled at evading therapies, with its cells going so far as to starve in order to stop the immune cells that would eradicate them. A team from the Weizmann Institute, including Prof. Yardena Samuels; the Netherlands Cancer Institute; and the University of Oslo have revealed one of melanoma’s tricks – never before seen in human cells – and a therapeutic target.
While quick-acting inhalers and medications can reduce inflammation during an asthma attack, people with asthma have few tools to prevent the next attack from coming. Now researchers at La Jolla Institute for Immunology (LJI) have discovered that blocking two immune molecules at the same time is key to preventing asthma attacks in a mouse model.
Researchers uncover defining features of a subset of T-cells that may drive autoimmunity in MS, and could prove to be a new target for therapy.
A multi-layered, virus-specific immune response is important for controlling SARS-CoV-2 during the acute phase of the infection and reducing COVID-19 disease severity, with the bulk of the evidence pointing to a much bigger role for T cells than antibodies.
At La Jolla Institute for Immunology (LJI) researchers are dedicated to finding a way to stop plaques from forming in the first place. In a new study, LJI scientists show that certain T lymphocytes, a type of white blood cell, that start out trying to fight the disease can end up increasing inflammation and making atherosclerosis cases even worse.
New study on how immune memory can be targeted and improve immunotherapy and prevent cancer recurrence.
SHAREInternational collaboration provides important piece of COVID-19 puzzleLA JOLLA—A new study from researchers at La Jolla Institute for Immunology (LJI) and Erasmus University Medical Center (Erasmus MC) shows that even the sickest COVID-19 patients produce T cells that help fight the virus. The study offers further evidence that a COVID-19 vaccine will need to elicit T cells to work alongside antibodies.
A new Weizmann Institute model of autoimmune disease may solve some major outstanding riddles, including what causes T cells to attack and why only certain organs get the diseases
Inspired by a tactic cancer cells use to evade the immune system, University of Pittsburgh researchers have engineered tiny particles that can trick the body into accepting transplanted tissue as its own, while leaving the immune system intact.
A multidisciplinary Michigan Medicine team is shedding new light on the role of regulatory T cells in pancreatic cancer — and, in mouse models, have uncovered a new potential target to improve immunotherapy approaches to the deadly disease.
Worldwide, more people die from tuberculosis than any other infectious disease, even though the vast majority were vaccinated. The vaccine just isn’t that reliable. But a new Nature study finds that simply changing the way the vaccine is administered could dramatically boost its protective power.
