STING protein activates a pathway that kills tumor-fighting immune cells

The immune protein STING has long been noted for helping protect against viruses and tumors by signaling a well-known immune molecule. Now, UT Southwestern scientists have revealed that STING also activates a separate pathway, one that directly kills tumor-fighting immune cells.

New bioluminescent reporter tracks DNA double stranded break repair in cells

A new bioluminescent reporter that tracks DNA double stranded break (DSB) repair in cells has been developed by researchers from Massachusetts General Hospital (MGH) and the Academia Sinica in Taiwan.

Novel molecular survival strategy of Shigella bacterium uncovered

Enteric pathogens, such as the bacterium Shigella, can cause severe intestinal disease with bloody diarrhea. In a new study, researchers from Tokyo Medical and Dental University (TMDU) discovered a novel molecular survival strategy by which Shigella is able to cause damage to the intestines despite two elaborate protective mechanisms used by host cells.

Study shows DNA damage causes cells to reprogram themselves into stem cells

Researchers have discovered that when DNA in the moss Physcomitrella patens is damaged, it causes cells to reprogram on their own to change into stem cells.

Scientists discover bacteria's secret weapon to evade immune responses

Monash Biomedicine Discovery Institute scientists have discovered a previously unknown method used by bacteria to evade immune responses.

Regulating cancer stemness using combination of nanotechnology and genetic engineering

The development of chemotherapeutic agents with selective anti-cancer activities is increasingly unattractive due to the emergence of resistance, poor targeting of cancer tissues, and subsequent metastasis.

Hydrogels based on modified pectins could be used for neural tissue restoration

Far Eastern Federal University (FEFU) scientists have developed implantable hydrogels based on plant polysaccharides (pectins). They can play the role of an artificial extracellular matrix, a special network of molecules that fills the space between body cells.

Mitochondrial reprogramming may offer new treatment strategies against breast cancer

A study performed has revealed that oxygen-deprived breast cancer cells transmit messages that cause oncogenic modifications in the surrounding healthy cells.

Study suggests that coronavirus does not directly damage taste bud cells

A new study from the Regenerative Bioscience Center at the University of Georgia is the first to suggest that COVID-19 does not directly damage taste bud cells.

Study indicates a powerful treatment for pulmonary fibrosis

A pre-clinical study led by scientists at Cincinnati Children's demonstrates that in mice the drug barasertib reverses the activation of fibroblasts that cause dangerous scar tissue to build up in the lungs of people with idiopathic pulmonary fibrosis (IPF).

Researchers identify mechanism that prevents death of neurons

When our neurons -- the principle cells of the brain -- die, so do we. Most neurons are created during embryonic development and have no "backup" after birth.

Novel method of communication relies on 'mechano-chemical' signals to control cell movement

Cells work around the clock to deliver, maintain, and control every aspect of life. And just as with humans, communication is a key to their success.

Fusion protein found to effective at treating pulmonary arterial hypertension

Pulmonary arterial hypertension (PAH) is an insidious disease. Symptoms may begin slowly, and even before they appear, extensive damage has caused the obstruction of small arteries leading to increased blood pressure in the lungs.

Environmental pollutants pose risks to finless porpoises

A new study has revealed that environmental pollutants pose toxicological risks to finless porpoises (Neophocaena asiaeorientalis).

Scientists gain insights into how parasitic bacterium gives rise to lesions

Bacteria of the genus Bartonella are parasites that can be transmitted to humans via insect bites and animal scratches, resulting in an infection known as "bartonellosis." Cat-scratch disease and trench fever are forms of bartonellosis caused by different Bartonella species infecting humans.

Study shows cathepsin B can be used as biomarker for traumatic brain injury

Scientists at the Walter Reed Army Institute for Research (WRAIR) have recently demonstrated that cathepsin B, a well-studied protein important to brain development and function, can be used as biomarker, or indicator of severity, for traumatic brain injury.

Fatty acid can kill cancer cells, study shows

Researchers have demonstrated that a fatty acid called dihomogamma-linolenic acid, or DGLA, can kill human cancer cells.

Study reveals the role of alpha-synuclein in Parkinson’s disease

In people affected by Parkinson’s, clusters of alpha-synuclein or α-synuclein, also referred to as the “Parkinson’s protein,” are detected in the brain.
