Scientists build a new model of CAR-T cells — Ones with Powerful “Armor” that allow them to fight Solid Tumors

Engineered T-cell therapy, and in particular CAR T-cells, have shown efficacy in CD-19+ blood cancer such as lymphomas and leukemias. However, to date, T-cell therapies have found little success in solid tumors – in part due to the immunosuppressive tumor microenvironment. Checkpoint inhibitors, on the other hand, have been proven effective at empowering the immune system to fight a variety of solid tumors. The checkpoint inhibitor antibody binds to a

Nuclear Pore Functions Are Essential for T Cell Survival

Study reveals an unexpected regulatory role for Nup210 in T cell homeostasis Nuclear pore complexes in the nuclear membrane not only control the transport of molecules into and out of the nucleus—they play an essential role in the survival of T cells. A new study by Sanford Burnham Prebys Medical Discovery Institute (SBP) researchers describes how a specific nuclear pore component is critical for the survival of circulating T cells.

Bioengineered Soft Microfibers Improve T-Cell Production

Columbia engineers bioengineer soft microfibers to improve T-cell production. T cells play a key role in the body’s immune response against pathogens. As a new class of therapeutic approaches, T cells are being harnessed to fight cancer, promising more precise, longer-lasting mitigation than traditional, chemical-based approaches. These “living drugs” are poised to transform medicine, with a growing number of cellular therapies receiving FDA-approval. A current bottleneck in these approaches and

First-In-Human Clinical Trial Aims to Extend Remission for Children and Young Adults With Leukemia Treated With T-Cell Immunotherapy

Phase 1 pilot study utilizes T-cell antigen presenting cells to prolong the persistence of cancer-fighting chimeric antigen receptor (CAR) T cells, reduce the relapse rate After phase 1 results of Seattle Children’s Pediatric Leukemia Adoptive Therapy (PLAT-02) trial have shown T-cell immunotherapy to be effective in getting  93 percent of patients with relapsed or refractory acute lymphoblastic leukemia (ALL) into complete initial remission, researchers have now opened a first-in-human clinical

Nanoparticles Reprogram Immune Cells to Fight Cancer

Researchers at Fred Hutchinson Cancer Research Center have developed biodegradable nanoparticles that can be used to genetically program immune cells to recognize and destroy cancer cells — while the immune cells are still inside the body. In a proof-of-principle study to be published April 17 in Nature Nanotechnology, the team showed that nanoparticle-programmed immune cells, known as T cells, can rapidly clear or slow the progression of leukemia in a

Penn Team Tracks Rare T Cells in Blood to Better Understand Annual Flu Vaccine

For most vaccines to work the body needs two cell types – B cells and T helper cells – to make antibodies. B cells are the antibody factories and the T helper cells refine the strength and accuracy of antibodies to home and attack their targets. A technique that identifies these helper immune cells could inform future vaccine design, especially for vulnerable populations. Flu vaccines work by priming the immune

Researchers Identify Possible Pathway to Reboot Immune System After Bone-Marrow Transplants

New research has shown how a cell surface molecule, Lymphotoxin β receptor, controls entry of T-cells into the thymus; and as such presents an opportunity to understanding why cancer patients who undergo bone-marrow transplant are slow to recover their immune system. The study, published in the Journal of Immunology, used mouse models to reveal an in vivo mechanism that researchers believe might also represent a novel pathway for immunotherapeutic targeting

St. Jude Researchers Reveal How Two Types of Immune Cells Can Arise From One

The fates of immune cells can be decided at the initial division of a cell. Researchers at St. Jude Children’s Research Hospital have discovered that the production of daughter cells with different roles in the immune system is driven by the lopsided distribution of the signaling protein c-Myc. Nudging c-Myc in one direction or the other could make vaccines more effective or advance immunotherapies for cancer treatment. The research appears
