Animal model yields important insights into T cell exhaustion

T lymphocytes, or T cells, are an important component of our immune system. They can recognize foreign proteins, so-called antigens, as peptide fragments - for instance, those derived from viruses or cancer cells.

Natural compounds in apples and other fruits may improve brain function

According to a new study, apples and other fruits contain natural substances that may help trigger the generation of new neurons in the brain.

Cell cycle of cancer cells can be disrupted using two commercially available inhibitors

With two commercially available inhibitors, the cell cycle of the cancer cells in the childhood tumor neuroblastoma can be disrupted at a key point causing tumor cell death.

N-terminal acetylation shields proteins from degradation and inhibits programmed cell death

A new study shows that proteins called IAPs, which can trigger programmed cell death, are inhibited by a specific chemical modification, and reveals that they play a wider role in protein quality control than previously assumed.

Study provides a causal link between the Alzheimer's risk gene and COVID-19

A City of Hope-led research team found that the same gene that increases the risk for Alzheimer's disease, ApoE4, can increase the susceptibility to and severity of COVID-19.

New method shows how pharmaceuticals induce cancer cell death

Cancer cells are smart when it comes to anti-cancer drugs, evolving and becoming resistant to even the strongest chemotherapies over time.

Targeting RNA splicing can trigger antiviral immune pathways in triple-negative breast cancers

Researchers at Baylor College of Medicine have discovered how therapeutics targeting RNA splicing can activate antiviral immune pathways in triple negative breast cancers (TNBC) to trigger tumor cell death and signal the body's immune response.

Anti-diarrhea drug could be used to induce cell death in glioblastoma cell lines

The research group led by Dr Sjoerd van Wijk from the Institute of Experimental Cancer Research in Paediatrics at Goethe University already two years ago found evidence indicating that the anti-diarrhea drug loperamide could be used to induce cell death in glioblastoma cell lines.

Researchers demonstrate potential preventive treatment for Crohn's disease

A potential preventive treatment for Crohn's disease, a form of inflammatory bowel disease, has been demonstrated in a mouse model and using immune-reactive T cells from patients with Crohn's disease.

Study may lead to new treatments for certain types of disease

Researchers at the Francis Crick Institute have found a new way to prevent some tumours from repairing their own DNA, a function that is essential for cancer cell survival. This discovery could lead to much needed new treatments for certain types of the disease.

Repair proteins can help healthy cells to avoid damage during cancer therapy

A key way radiation therapy and chemotherapy work is by making highly lethal double-strand breaks in the DNA of cancer cells.

Researchers discover molecular mechanism of plant immune receptors

In a recent study, Alexander von Humboldt Professor Jijie Chai at the University of Cologne and his team together with MPIPZ researchers have succeeded for the first time in reconstructing the sequence of molecular events that activate an inactive plant immune receptor and thus mediate the death of the host cell.

Study determines 3D structure of molecular machine involved in placement of key proteins

Within a single cell, more than a quarter of all proteins are found in the membrane, in which they carry out crucial functions.

Gasdermin E triggers pyroptosis and involved in pathogen-induced coral death

Pyroptosis is a highly inflammatory form of programmed necrotic cell death that acts as a defense mechanism against the infection of bacterial and viral pathogens. Pyroptosis is executed by gasdermin, a family of pore-forming proteins.

Study may lead to novel organisms that are more efficient at converting plants into biofuels

A new study reveals how bacteria control the chemicals produced from consuming 'food.' The insight could lead to organisms that are more efficient at converting plants into biofuels.

Drug meant for bacterial infections can combat weight gain

A drug originally developed to treat bacterial infections has proved capable of boosting the metabolism and attenuating the weight gain induced by a fatty diet in tests with mice. The study was conducted at the University of Campinas (UNICAMP) with FAPESP's support, and the findings have just been published in the journal Science Advances.

Specific immune mechanism in COVID-19 patients triggers inflammatory process

Researchers at the University of São Paulo (USP) in Brazil have demonstrated for the first time that in COVID-19 patients an immune mechanism known as the inflammasome participates in activation of the inflammatory process that can damage several organs and even lead to death.

Researchers determine role of NLRP1 protein in detecting the common cold virus

The role of a protein in detecting the common cold virus and kickstarting an immune response to fight infection has been uncovered by a team of scientists from Nanyang Technological University, Singapore (NTU Singapore), the Agency for Science, Technology and Research (A*STAR) and the National University of Singapore.

Study identifies a promising target for cancer treatment

If there is a positive aspect in cancer’s random biology, it is that the same characteristics that promote the growth of cancer cells usually present opportunities for destroying them.

Protein interactions could serve as therapeutic targets to treat viral infections

Researchers have investigated the role of the interplays within the proteins membranes of viral families involved in the control of programmed cell death.
