Researchers discover murderous survival strategy of yeast

Yeast is not the simple single-celled microorganism we once thought, but a competitive killer. When starved of glucose, yeast releases a toxin that will poison other microorganisms that have entered its surrounding habitat, even its own clones.

Understanding immune cell function to improve vaccine efficacy

The immune system’s capacity to remember defeated disease-causing germs and avoid recurrent infections is still poorly understood, but a new study published in Science Immunology fills in some gaps.

Researchers uncover a mechanism of flowering plant sperm compaction

Sperm cells have compact bundles of DNA, yet exactly how and why sperm cell nuclei are condensed in flowering plants has been a mystery, until now.

The primary functions of innate immune cells

An inflammation and a rise in mucus production are typical signs of allergies and worm infections. The innate immune cells are involved in this immunological response, although it is still unclear exactly what they do.

Different cancers carry distinctive genetic signatures

After analyzing data from a public repository, CD4-T, CD8-T cells, and Treg cells, a team of researchers led by bioinformatics Mabel Vidal from the University of Concepcion and working with researchers from MELISA Institute and other academic institutions discovered a distinctive genetic signature among subsets of infiltrating T cells of various types of cancer.

“Screen-first” approach mines microbes directly from the environment

The best method now available for researchers to isolate a specific microorganism with a given metabolic function from an environment is to collect a sample of cells, culture them, and then test them for the desired cell functions.

New bioprinting platform to replicate tumors in 3D spheroids

Bowel cancer patients could in future benefit from a new 3D bioprinting technology which would use their own cells to replicate the complex cellular environment of solid tumors in 3D models.

Discovery may help alleviate the increasing global problem of high soil salinity on farmland

To avoid salt in soil, plants can change their root direction and grow away from saline areas. University of Copenhagen researchers helped find out what makes this possible.

New technique could help fine-tune the production of useful proteins

Using an approach based on CRISPR proteins, MIT researchers have developed a new way to precisely control the amount of a particular protein that is produced in mammalian cells.

Quantifying microanatomical tissue structures without human intervention

Scientists at Weill Cornell Medicine have created a computational method for mapping the architecture of human tissues in extraordinary detail. Their method guarantees to expedite research on organ-scale cellular interactions and could lead to strong new diagnostic strategies for a variety of disorders.

New approach to clear early stage pre-cancerous tumor cells

A novel method of reprogramming the immune cells to shrink or destroy cancer cells has been demonstrated to work in melanoma, a difficult to treat and destructive skin cancer.

Genetic timestamping tracks the fate of plasma cells over time

Vaccines function by effectively producing immune cells that live for a long time, frequently for decades. These immune cells form a protective barrier that prevents or reduces re-infection, as well as a memory that enables one to identify an old invader, such as a virus, and eliminate it before it causes disease.

Potential therapeutic strategy for medulloblastoma relapse

Medulloblastoma, a kind of malignant brain tumor, can develop resistance to therapy, resulting in relapse. Uppsala University scientists found a protein that causes tumor cells to rest and become insensitive to radiation treatment.

Resistance against Epstein-Barr virus from experimental monoclonal antibodies

When tested in a lab setting using human cells, a panel of experimental monoclonal antibodies (mAbs) that target various Epstein-Barr virus (EBV) sites prevented infection.

Identifying the structure of the SEA complex

The mTOR protein is important for cell growth, proliferation, and survival. Its activity fluctuates according to nutrient availability and growth factors like hormones.

Metabolite from pomegranate to boost immune cells that fight tumors

Researchers from the Georg-Speyer-Haus in Frankfurt am Main, Germany, and Goethe University Frankfurt have succeeded in developing a new strategy for the treatment of colorectal cancer as part of an interdisciplinary initiative of the LOEWE Center Frankfurt Cancer Institute (FCI).

Immunological mechanisms behind the development of alloantibodies

Hemophilia A is the most frequent severe variant of hemophilia. It nearly mostly affects men. The condition is frequently treatable, although not for all patients. A study at the University of Bonn has now highlighted a critical mechanism required for the therapy to be efficient.
