Apoptosis is programmed cell death, the body's normal method of disposing of damaged, unwanted, or unneeded cells.

Study increases knowledge of the genetics behind aortic aneurysm

A new study increases knowledge of the genetics behind aortic aneurysm, a disease that can spark life-threatening events like aortic dissections and ruptures.

How SARS-CoV-2 infects the brain

While there is no official explanation on how SARS-CoV-2 travels to the brain, a new review published in the journal Fluids and Barriers of the CNS concluded that there is insufficient evidence on COVID-induced neurological problems coming from a direct invasion of SARS-CoV-2 into the brain.

New algorithm can be a more effective way to analyze models of biological systems

From biochemical reactions that produce cancers, to the latest memes virally spreading across social media, simple actions can generate complex behaviors.

Study opens up new opportunities for controlling tuberculosis

Boosting the body's own disease-fighting immune pathway could provide answers in the desperate search for new treatments for tuberculosis.

Antiviral activity of long-chain polyphosphates against SARS-CoV-2 infection

A new study has been published in Science Signaling that has examined the potential role that long-chain inorganic polyphosphates (polyPs) play against SARS-CoV-2 infection.

Enzyme inhibitor boosts immune system to fight MRSA and other dangerous skin infections

In what turned out to be one of the most important accidents of all time, Scottish bacteriologist Alexander Fleming returned to his laboratory after a vacation in 1928 to find a clear zone surrounding a piece of mold that had infiltrated a petri dish full of Staphylococcus aureus (S. aureus), a common skin bacterium he was growing.

RNA-binding proteins represent a new class of drug targets for triple-negative breast cancer

In cancer research, it's a common goal to find something about cancer cells -- some sort of molecule -- that drives their ability to survive, and determine if that molecule could be inhibited with a drug, halting tumor growth. Even better: The molecule isn't present in healthy cells, so they remain untouched by the new therapy.

Researchers develop the world's first digital cancer cell model

The computer model, developed under the lead management of researchers at TU Graz, simulates the cyclical changes in the membrane potential of a cancer cell using the example of human lung adenocarcinoma and opens up completely new avenues in cancer research.

Reactive oxygen species are important components in cancer treatments

Reactive oxygen species (ROS) are highly reactive chemicals which contain oxygen radicals. Hypochlorous acid, peroxides, superoxide, singlet oxygen, alpha-oxygen and hydroxyl radicals are the major examples of ROS, which are familiar to persons from many walks of life as they are used in many domestic and industrial processes.

Ion channel conserved in coronaviruses a potential new drug target for COVID therapeutics

To this end, a recent study published in Nature Structural & Molecular Biology discusses the structures of the SARS-CoV-2 ORF3a using cryo-electron microscopy (cryo-EM).

Is mild COVID-19 in children due to stronger antiviral innate immunity in the upper airway?

A new preprint on the medRxiv* server adds fuel to this train of thought, showing that the required cell program is already active in children – namely, a higher expression of specific pattern recognition receptors (PRRs), which mediate an interferon (IFN) response.

Differences in monocyte subsets between severe COVID-19 and long COVID

Researchers in the United States and Costa Rica have identified differences in the proportions of monocyte subsets that occur in severe cases of coronavirus disease 2019 (COVID-19) following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and post-acute sequelae of COVID-19 (PASC), often referred to as “Long COVID”.

Antagonism of glucocorticoid receptors promotes apoptosis in solid tumor cells

Oncotarget published "Glucocorticoid receptor antagonism promotes apoptosis in solid tumor cells" which reported that to guide studies in cancer patients, relacorilant, an investigational selective GR modulator that antagonizes cortisol activity, was assessed in various tumor types, with multiple cytotoxic combination partners, and in the presence of physiological cortisol concentrations.

WEHI collaborates with Boehringer Ingelheim to develop novel anti-cancer therapeutics

WEHI has partnered with Boehringer Ingelheim, a leading research-driven pharmaceutical company, in a collaboration to discover and develop anti-cancer therapeutics using a promising new technology called targeted protein degradation.

SARS-CoV-2 causes ER-stress-activated unfolded protein response leading to cell death

A new study describes the varying ways in which the virus co-opts the machinery of the host cell following infection to evade or modulate the host immune response, alter the pattern of translation of viral proteins, and the release of new viral particles.

Researchers study COVID-19 immune dysfunction in relation to phosphatidylserine

Often patients suffering from COVID-19 (coronavirus disease) show striking immune dysregulation - causing increased morbidity and mortality. Mechanisms for adaptive immune disturbance, lymphopenia, and thromboinflammation in COVID-19 are still poorly understood.

Viral phosphoesterases (including in CoVs) can restrict antiviral innate immunity

An interesting new study describes the activities of a family of viral enzymes called two-histidine-phosphoesterases (2H-PEs), found in coronaviruses (CoVs) and rotaviruses, as well as a mammalian A-kinase anchoring protein enzyme, AKAP7, that shares the same function. Together called 2’,5’-PEs, these enzymes all break down 2’,5’-oligoadenylate compounds that activate the antiviral enzyme ribonuclease L (RNase L).

Inhibiting necroptosis could be a novel approach for treating COPD

Research shows that inhibiting necroptosis, a form of cell death, could be a novel therapeutic approach for treating chronic obstructive pulmonary disease, an inflammatory lung condition, also known as emphysema, that makes it difficult to breathe.

Novel altruistic stem cell defense mechanism may be targeted to develop new COVID-19 vaccines

The SARS-CoV-2 virus that causes COVID-19 may have the ability to reactivate dormant tuberculosis (TB). In a novel study scientists report in The American Journal of Pathology that infection with a specific coronavirus strain reactivated dormant Mycobacterium tuberculosis (MTB) in mice.

Reducing coronavirus-related mortality through senolytics

A study recently published in the journal Science explores the concept of senescent cells (SnC) having a hyperinflammatory response and the use of a class of small molecules called senolytics to combat this.
