Yale study links some long COVID patients to autoimmune responses

A Mount Sinai-led research team has demonstrated that autoimmunity, in which the body’s immune system attacks its own tissues, is responsible for the often-debilitating and confounding symptoms of long COVID in a subset of people.

Findings from the study, published in Cell, could lead to important new approaches to treating patients with long COVID, including already-validated therapies for management of autoimmunity as well as new ways of clinically identifying which patients are most likely to benefit from these therapies.

Autoimmunity emerges as key driver
“We’ve known for some time that long COVID involves not just one but a variety of phenotypes, and now we have validated that autoimmunity is a major contributor to the symptom burden,” says David Putrino, Ph.D...

How cancer hijacks the immune system by draining T cells’ energy

Research into immunotherapy against cancer typically focuses on better recognition of cancer cells by the body’s own immune system. Researchers at Amsterdam UMC and Moffitt Cancer Center have taken a different approach.

They investigated how cancer affects the energy management of a patient’s T cells and showed for the first time that contact with chronic lymphocytic leukemia (CLL) cells leads to a serious energy crisis in these cells.

These findings are published in Cellular & Molecular Immunology, building on a publication in the Blood Journal.

CLL is the most common type of leukemia in the Western world and mainly affects the elderly. Despite new therapies, the disease remains incurable, and treatments are becoming increasingly expensive.

Some c...

Engineered Killer Immune Cells Target Tumors and their Immunosuppressive Allies

D-L1 CAR haNKs demonstrated superior killing of murine HNSCC targets compared to haNKs.

Scientists have engineered natural killer immune cells that not only kill head and neck tumour cells in mice but also reduce the immune-suppressing myeloid cells that allow tumours to evade the immune response, according to a new study in eLife.

The engineered cell therapy could be used as an alternative approach for treating cancer in patients for whom previous immunotherapy based on the activation of T cells has failed. These findings are reported by researchers at the U.S. National Institutes of Health (NIH) in Bethesda, Maryland.

In recent years, treatments called T-cell therapy or CAR-T cell therapy have been approved to treat blood cancers, and many others are now in development for othe...

Scientists create a Renewable Source of Cancer-fighting T cells

Organoid-Induced Differentiation of Conventional T Cells from Human Pluripotent Stem Cells

A study by UCLA researchers is the first to demonstrate a technique for coaxing pluripotent stem cells – which can give rise to every cell type in the body and which can be grown indefinitely in the lab – into becoming mature T cells capable of killing tumor cells.

The technique uses structures called artificial thymic organoids, which work by mimicking the environment of the thymus, the organ in which T cells develop from blood stem cells.

T cells are cells of the immune system that fight infections, but also have the potential to eliminate cancer cells...
