Regulatory T cells produced in the gut play a role in repairing injured muscles

The human immune system is incredibly versatile. Among its most skilled multitaskers are T cells, known for their role in everything from fighting infection to reining in inflammation to killing nascent tumors.

New biomarker helps identify biological age

Once considered to be incompetent in encoding proteins due to their simple monotonous DNA repetitions, tiny telomeres at the tips of human chromosomes now appear to have a powerful biological function that could help better understand cancer and aging.

Toxic protein likely to be the cause of two rare genetic disorders identified

Scientists at the National Institutes of Health and their co-workers reported that DUX4, a toxic protein produced by the body, might just be the reason for two completely different rare genetic disorders.

Iron-dependent cell death can be used to improve immunotherapies against liver cancer

Iron-dependent cell death (ferroptosis) is a type of programmed cell death by means of which the body kills off diseased, defective or superfluous cells.

Adding antioxidants to cell cultures for efficient production of antibodies

Researchers at the Department of Chemical Engineering, Indian Institute of Technology, India, have investigated the effects of oxidative stress on the production of monoclonal antibodies (mAbs), and how antioxidants can alleviate this stress to improve their performance.

How the immune response in the brain aggravates epilepsy

Biologists at the University of Iowa have conclusively connected epilepsy with the brain’s immune system.

Study reveals the mechanisms that prevent effective cancer cell death

Cancer is a disease driven by gene mutations. These mutated genes in cancer fall into two major categories: tumor suppressors and oncogenes. Mutations in tumor suppressor genes can allow tumors to grow unchecked – a case of no brakes – while mutations in oncogenes can activate cell proliferation, pushing the gas pedal all the way to the floor.

A treatment strategy to hasten cancer cell death

Gene mutations are the cause of cancer. Tumor suppressors and oncogenes are the two main groups of these altered genes in cancer. Mutations in oncogenes can drive cell proliferation, pushing the gas pedal to the floor, whereas mutations in tumor suppressor genes can cause tumors to grow unchecked—a situation in which there is no control.

Telomeres, mitochondria, and inflammation: Working in synergy to fight cancer

The telomeres, or ends of the chromosomes, increasingly shorten as people age. Recently, Salk researchers found that when telomeres are very short, they can still interact with the mitochondria, the cell’s powerhouses.

Novel combination therapy shows promise in acute myeloid leukemia

Acute myeloid leukemia (AML) is an aggressive form of cancer that originates in the bone marrow, rapidly spreads to the blood and can quickly cause death if not treated promptly.

Innovative cancer therapy options with new cell death mechanism

Researchers from The University of Texas MD Anderson Cancer Center have described a previously unrecognized type of cell death called disulfidptosis in a study that was published in Nature Cell Biology.

Massive clinical study on type 1 diabetes patients

A massive clinical study on an approved psoriasis drug is now underway. The drug will be tested on people who have just been diagnosed with type 1 diabetes. The drug, according to the theory, could preserve the patient’s remaining insulin production.

Figuring out how cells safeguard their genomes during replication

Cells zealously protect the integrity of their genomes, because damage can lead to cancer or cell death. The genome, a cell’s complete set of DNA, is most vulnerable while it is being duplicated before a cell divides.

Study sheds new light on a lifestyle switch that occurs in marine bacteria

Scientists have detailed a lifestyle switch that occurs in marine bacteria, where they change from coexisting with algae hosts in a mutually beneficial interaction to suddenly killing them.

Revealing the unappreciated role of POLQ in responding to DNA replication stress

Researchers at the Francis Crick Institute, in partnership with Artios, have discovered how an enzyme involved in DNA repair (POLQ) becomes critical to the survival of some tumors when the cancer cells lose the ability to employ a more frequent way of DNA repair.

The critical role of amino acid sensing pathways in driving colorectal cancer

A dietary modification may be essential to improving colon cancer treatment, according to research from the University of Michigan Rogel Cancer Center.

Mitochondria play a crucial role in the regulation of the NF-κB signaling pathway

Mitochondria are highly regarded as the cell's powerhouse. However, these cellular organelles are essential for more than only energy production: Professor Konstanze Winklhofer and her colleagues at Ruhr University Bochum’s Faculty of Medicine have found that mitochondria play an essential role in signal transduction in innate immune pathways.
