Scientists reveal how critical enzyme in the cell works

S-acylation is the process of chemically linking a lipid to protein via a thioester bond. It is an important process of the cell that regulates the localization and function of numerous proteins.

Researchers generate thyroid mini-organs in the lab

Hormones produced by the thyroid gland are essential regulators of organ function. The absence of these hormones either through thyroid dysfunction due to, for example, irradiation, thyroid cancer or autoimmune disease or thyroidectomy leads to symptoms like fatigue, feeling cold, constipation, and weight gain.

Comprehensive mutation map helps better understand the biological processes underlying Alzheimer's

A study published in the journal eLife made all the possible mutations in the amyloid beta peptide and tested how they influence its aggregation into plaques, a pathological hallmark of Alzheimer's disease.

Adhesion strength and contractility enable metastatic cancer cells to display adurotactic behavior

Bioengineers at the University of California San Diego and San Diego State University have discovered a key feature that allows cancer cells to break from typical cell behavior and migrate away from the stiffer tissue in a tumor, shedding light on the process of metastasis and offering possible new targets for cancer therapies.

Immune cells in cerebrospinal fluid could be biomarkers to predict immunotherapy response

Results from a study led by Joan Seoane, Director of Preclinical and Translational Research co-program at VHIO and ICREA Professor, show that immune cells accessing cerebrospinal fluid faithfully recapitulate the characteristics of cells identified in brain metastasis, and could therefore constitute novel biomarkers of response to immune-based therapies.

New substance could improve the treatment of drug-resistant cancers

A new substance could improve the treatment of persistent cancers. Researchers at Martin Luther University Halle-Wittenberg and the University of Greifswald have developed a new inhibitor that makes drug-resistant tumor cells respond again to chemotherapy.

Mutant protein plays key role in Huntington’s disease

Back in 1993, researchers had discovered that Huntington’s disease is typically caused by a single mutated gene, known as HTT.

Study identifies molecular mechanism by which HSPCs recover after chemotherapy-induced injury

Chemotherapy has a damaging effect on hematopoietic stem and progenitor cells (HSPCs) in bone marrow. However, once chemotherapy ends, HSPCs regenerate, a process that has remained unknown--until now.

Mutant peptides derived from SARS-CoV-2 hamper activation of CD8+ killer T cells

A deep sequencing study of 747 SARS-CoV-2 virus isolates has revealed mutant peptides derived from the virus that cannot effectively bind to critical proteins on the surface of infected cells and, in turn, hamper activation of CD8+ killer T cells that recognize and destroy these infected cells.

Engineered safety switch reduces CAR-T immunotherapy-related side effects

UNC Lineberger Comprehensive Cancer Center researchers have successfully used an experimental safety switch, incorporated as part of a chimeric antigen receptor T-cell (CAR-T) therapy, a type of immunotherapy, to reduce the severity of treatment side effects that sometimes occur.
