Study: Phase separated droplets have many important functions in cells

Autophagy is a fundamental cellular process by which cells capture and degrade their own dysfunctional or superfluous components for degradation and recycling.

Electrical trigger sites in the brain change with experience, shows study

To process information in our brains, nerve cells produce brief electrical impulses, called action potentials, triggered from one highly specialized region.

Immature dendritic cells in young children can induce robust immune responses

A new study performed by scientists from Ludwig-Maximilians-Universitaet Muenchen (LMU) has demonstrated that putatively immature dendritic cells in young children can trigger powerful immune responses. The findings may result in better vaccination protocols.

Study identifies new mode of male endocrine disruption due to environmental arsenic exposure

Arsenic exists ubiquitously in an organic or inorganic state in the environment. General populations are commonly exposed to arsenic by digestion.

Investigational antisense medicine lowers disease burden, reduces myeloma cell abundance in mice

Many patients with multiple myeloma, a type of blood cancer, eventually develop resistance to one treatment after another. That's in part because cancer stem cells drive the disease -- cells that continually self-renew. If a therapy can't completely destroy these malignant stem cells, the cancer is likely to keep coming back.

COVID-19 virus triggers antibody response from prior coronavirus infections

According to the results of a study, the immune systems of COVID-19 patients may depend on antibodies that were produced during infections from previous coronaviruses to help combat the disease.

Study reveals genetic variants that increase the risk of nocturnal enuresis

In a large-scale study of Danish children and young people, researchers from Aarhus University have for the first time found genetic variants that increase the risk of nocturnal enuresis - commonly known as bedwetting or nighttime incontinence. The findings provide completely new insights into the processes in the body causing this widespread phenomenon.

Viral relatives of SARS-CoV-2 can evolve to evade the human immune system

Scientists have shown that two species of seasonal human coronavirus related to SARS-CoV-2 can evolve in certain proteins to escape recognition by the immune system, according to a study published today in eLife.

Functions of gamma delta T cells are regulated by sugars and fat Gene, shows study

The team led by Bruno Silva Santos, Principal Investigator and Deputy Director of the Instituto de Medicina Molecular João Lobo Antunes (iMM) and Professor at the Faculdade de Medicina da Universidade de Lisboa, discovered that the functions of a subtype of white blood cells - gamma delta T cells - are regulated by metabolic resources, namely sugars and fat.

Study shows how nonmalignant cells adapt to harsh tumor microenvironment

Cells need energy to survive and thrive. Generally, if oxygen is available, cells will oxidize glucose to carbon dioxide, which is very efficient, much like burning gasoline in your car. However, even in the presence of adequate oxygen, many malignant cells choose instead to ferment glucose to lactic acid, which is a much less efficient process.

Researchers define cancer invasion machinery orchestrated by cancer gene

Researchers at the University of Helsinki have defined a cancer invasion machinery, which is orchestrated by a frequently mutated cancer gene called Ras. When signaling from Ras protein becomes abnormally high, like it does in many cancers, this switches on the cellular machinery that helps the cancer cells to depart from the tissue from which the cells have developed.

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.

New computational technique accurately differentiates between normal and cancer cells

Scientists have created a new method to precisely differentiate between data from a wide range of normal cells and cancer cells found inside tumor samples.

Study explains operating mode of mitochondrial sorting and assembly machinery

Mitochondria are vital for the human body as cellular powerhouses: They possess more than 1,000 different proteins, required for many central metabolic pathways. Disfunction of these leads to severe diseases, especially of the nervous system and the heart.
