Researchers discovered that activating the pentose phosphate pathway makes antitumor CD8 T cells more likely to stay in an immature state, leading to better results in animal models and human organoids. This metabolic reprogramming strategy may enhance checkpoint inhibitor therapy by boosting a long-term supply of active cytotoxic T ce...
Researchers at Cold Spring Harbor Laboratory have discovered that innate-like T cells mature differently in humans than in mice, with age playing a critical role in their development. This finding has significant implications for the development of immunotherapeutics, highlighting the need to consider human-specific differences when te...
Researchers at the University of Wisconsin-Madison have developed a new method to treat cancer using T cells, which was discovered by chance. The two-step process 'metabolically priming' enhances the ability of T cells to target tumors and survive longer in the body.
Researchers have identified a new autoimmune disorder that disrupts tooth enamel development, specifically in children with celiac disease. The disorder is linked to the immune system's faulty education process, leading to autoantibody production that damages permanent teeth.
Researchers developed a flexible new platform that solves part of the daunting delivery problem in cell and gene therapies. The workhorses behind this platform are extracellular vesicles, which bind to target cells and effectively transfer drugs inside.
Researchers mapped transcription factors in T cells infiltrating tumors, finding ways to increase anticancer efficacy by promoting or blocking T-cell differentiation. The findings have implications for cancer immunotherapy and provide new potential strategies to enhance immunotherapy.
Recent research on gamma delta T cells has made significant progress in understanding their role in antitumor immune response. Key findings include the identification of various hidden mechanisms and a strong association between tumor-infiltrating gamma delta T cells and patient survival.
Researchers developed a method to produce generic CAR T cells from induced pluripotent stem cells (iPS cells), which could be produced at scale for multiple patients. The new cells showed enhanced anti-tumor activity and comparable efficacy to current clinical-grade cells.
Researchers discovered that the TCF-1 protein enables plasticity in cells across neighborhoods during T cell development, weakening insulation and increasing interactions between adjacent neighborhoods. This finding sheds new light on immunotherapy approaches and could lead to more efficient cancer treatments.
Researchers at NYU Langone Health discovered that sphingosine 1 phosphate (S1P) levels in lymph nodes increase as the immune response mounts, leading to inflammation and damage. This finding could lead to better drugs used to fight inflammation, such as medications already approved for inflammatory bowel disease and multiple sclerosis.
A study led by George Hajishengallis found that targeting the DEL-1 molecule could be an effective way to treat inflammatory and autoimmune conditions. The researchers discovered that DEL-1 promotes the generation and immunosuppressive activity of regulatory T cells, which are crucial in maintaining health.
Researchers at Cincinnati Children's Hospital Medical Center identified the transcription factor activator protein 1 (AP-1) as critical to the formation of mature and fully functioning T cells. AP-1 helps open up chromatin, a twisted structure of DNA that controls cell activation.
Researchers at UCLA create mature T cells capable of killing tumor cells from pluripotent stem cells using artificial thymic organoids. This breakthrough technique has the potential to lead to new approaches to cancer immunotherapy and create a virtually unlimited supply of T cells.
Researchers have discovered that mature CD4+ helper T lymphocytes can reprogram into killer-like CD8+ T lymphocytes, gaining killing functions. This unexpected plasticity expands the functional capabilities of CD4+ T cells, suggesting they may play a direct protective role in immune responses.
Researchers found purified blood stem cells outperform those with T cells in forming new blood cells and regenerating lymphoid tissues. The study challenges decades-old assumptions about the need for T cells in bone marrow transplants.
Scientists studied how mice fight off intestinal worm infections to discover the immune system's versatility. They found that B cells produce cytokines, presenting proteins from invaders to T cells, which are crucial for a successful response.
Researchers at the University of Pennsylvania School of Medicine have found that juvenile cells on their way to becoming mature immune cells can develop into either T cells or other blood-cell types. This challenges the currently accepted model of T-cell development, which suggests that these cells are committed to the T-cell path from...
Researchers at Sunnybrook Health Sciences Centre have made a critical discovery in T cell development, understanding which molecular sets are required to induce different types of T cells. This finding brings immunologists closer to creating tailored T cell therapy for patients with AIDS or other immune system deficiencies.
A new genetic switch has been discovered in the process of T-cell maturation, which is a two-stage process. This finding could lead to ways to produce T-cells in the lab and potentially treat diseases such as AIDS.
Researchers use new microscopy techniques to observe immune cell behavior in living tissues, revealing prolonged contact between T cells and dendritic cells. This study paves the way for future work on T-cell activation and provides a new glimpse into key steps in early immune responses.
Researchers found that HIV preferentially infects HIV-specific CD4+ T cells, which are essential for directing the immune system's response to pathogens. This phenomenon highlights the vulnerability of these cells to viral infection and suggests ways to design a more effective HIV vaccine.
Scientists at UCSF deciphered a pattern of signals that determine the survival of T cells, the body's natural defense arsenal. The research identifies a new role for chemical messages between the immune system and a steroid hormone signal, which may control stress-induced hormone imbalance and autoimmune diseases.
Researchers from MGH discover that a protein called SDF-1 not only attracts but also repels T cells at high concentrations. This finding opens up potential new ways to manipulate the immune system for treatment of autoimmune diseases and organ transplantation.
Researchers at Duke University Medical Center have successfully transplanted discarded thymus tissue into two infants with DiGeorge Syndrome, restoring their immune systems and providing long-term treatment. The children's new gland has provided a normally functioning immune system that requires no long-term drug support.
The study identifies a mechanism by which the immune system eliminates dysfunctional T cells, which can lead to autoimmune diseases and cancer. The research suggests that continuous contact with class I MHC proteins is essential for maintaining the balance between cell survival and death.
Researchers have made progress toward a gene therapy for HIV infection by genetically altering virus-fighting T-cells to recognize and attack HIV-infected cells. The study found that engineered T-cells persisted in the bloodstream for at least 100 days after infusion, proliferating and providing long-term immunity.
Researchers at Duke University have made significant advancements in rebuilding the human immune system using thymus transplants. The breakthroughs offer new hope for patients with severe immunodeficiencies and potentially life-threatening illnesses.
