Scientists demonstrate a new function of an enzyme that connects to age-related diseases

Aging and age-related diseases present a complex challenge to biomedical researchers.

Researchers conduct a comprehensive survey of the aging epigenome across the chromatin hierarchy

Highly structured chromatin encodes the program of life with only one set of genes in the core of every cell. Since various genes are stimulated at different periods of life while staying silent elsewhere, this is feasible. Some genes from a former life stage are hidden deep within the nuclear perimeter, while others manage to break out.

Study reveals key characteristics of immune cells in ovarian cancer

Ovarian cancer is a difficult to diagnose malignancy that is often caught at a more advanced stage. Treatments for this cancer have changed little over the past few decades, with surgery and chemotherapy being the most common therapeutic approaches.

Researchers create RNA molecules to address human pancreatic beta cells

Researchers at the University of Miami Miller School of Medicine have created RNA molecules that bind to human pancreatic beta cells, which generate insulin and are destroyed in type 1 and type 2 diabetes patients.

Checkpoint immunotherapy acts as an interface between killer T cells and dendritic cells

Chronic viral infections and cancers can damage the immune system permanently, diminishing the ability of immune killer T cells to destroy tumor cells or virus-infected cells—a condition known as “immune exhaustion.”

HIF-1alpha inhibitor preserves the activity of insulin-producing beta cells in diabetic mice

High blood glucose is responsible for several complications in type 1 and type 2 diabetes. Researchers at Karolinska Institutet in Sweden have identified a new antidiabetic substance that preserves the activity of insulin-producing beta cells and prevents high blood glucose in mice.

CAR-T cell treatment via implantable biotechnology more effective in combating cancer

Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed an implantable biotechnology that produces and releases CAR-T cells for attacking cancerous tumors.

Single-cell spatial analysis may provide information about neoadjuvant therapy for triple-negative breast cancer

A next-generation technology that allows the study of protein expression at the single-cell level and the location of the cells within the tumor microenvironment (TME) was feasible and provided information on the benefit of adding the immune checkpoint inhibitor atezolizumab (Tecentriq) to chemotherapy as neoadjuvant treatment for patients with early high-risk and locally advanced triple negative breast cancer (TNBC), according to results presented at the San Antonio Breast Cancer Symposium, held December 7-10, 2021.

Pacific Ocean rockfish genomes offer new insights into the genetic determinants of aging

Genomes assembled from Pacific Ocean rockfishes – some species of which are among the longest-living vertebrates known – reveal new insights into the genetic determinants of aging.

Study reveals what causes T cells to be non-responsive to immunotherapy

Non-small cell lung cancer is the most common type of lung cancer in humans. Some patients with NSCLC receive a therapy called immune checkpoint blockade (ICB) that helps kill cancer cells by reinvigorating a subset of immune cells called T cells, which are "exhausted" and have stopped working.

Vaccinating against certain cancer proteins can boost overall immune response and shrink tumors

Over the past decade, scientists have been exploring vaccination as a way to help fight cancer. These experimental cancer vaccines are designed to stimulate the body's own immune system to destroy a tumor, by injecting fragments of cancer proteins found on the tumor.

Loss of natural HIV control preceded by functional impairment of T cells

HIV is a master of evading the immune system, using a variety of methods to prevent the body from being able to find and kill it.

Stem-like T cells found in certain lymph nodes could be natural cancer fighters

Researchers performed a new study and demonstrated that stem-like T cells found in some lymph nodes could exhibit natural cancer-fighting properties.

New study could prevent T cell exhaustion in the immune system’s fight against cancer

Struggling against a tumor is not a sprint. It is a marathon. The race of cancer-fighting T cells is at times simply very long, and the T cells give up fighting. This phenomenon is referred to as T cell exhaustion by researchers.

Therapy using artificial metalloenzymes helps reduce tumor growth, finds study

A new study has shown that it is viable to reduce tumor growth by a therapy that involves tagging cancer cells with various therapeutic molecules.

Study shows how WAVE2 protein maintains the immune system balance

Sinai Health researchers have reported that they have uncovered a new mechanism that regulates harmful overreactions in the body’s immune system.

Mitigating the negative impacts of artificial light at night on wildlife

Artificial light at night (ALAN) is a major factor in global insect decline. In a paper published today in Insect Conservation and Diversity, Smithsonian Conservation Biology Institute (SCBI) scientists and partners found that using amber-colored filters to remove the blue spectra of light from "warm white" LED (light-emitting diode) lamps drastically reduces insect attraction to nocturnal lighting in a tropical forest.

Study sheds light on how T cells specialize to combat pathogens

Scientists from the University of Basel have gained insights into the specialization of T cells.

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.
