Scientists unearth some of the biological mechanisms behind ferroptosis

A team of researchers at Tohoku University has unearthed some of the biological mechanisms of ferroptosis, a recently discovered type of regulated cell death that is triggered by iron and the accumulation of lipid peroxidation - lipids that have undergone oxidative degeneration.

Structure of cellular shredders varies according to cell type, study shows

"Miniature shredders" are at work in each cell, disassembling and recycling cell components that are defective or no longer required.

Gut dysbiosis and sepsis susceptibility among pregnant women

Researchers describe the role of gut dysbiosis during pregnancy in promoting excessive macrophage pyroptosis, which increases vulnerability to sepsis.

Study shows activation of pulmonary macrophages by SARS-CoV-2 spike glycoprotein

In a recent study published in the International Journal of Molecular Sciences, researchers investigated the effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike (S) glycoprotein on human lung macrophage (HLM) activation and angiotensin-converting enzyme 2 (ACE2) and transmembrane serine protease 2 (TMPRSS2) expression in human lung macrophages.

Understanding the mechanisms involved in heart disease and cancers

In a crucial step towards understanding the mechanisms involved in cardiovascular disease and certain cancers, a Canadian led research team has succeeded in a world first: they've found the molecular mechanism by which the protein PCSK9 degrades the receptor of low density lipoproteins, the richest cholesterol particles in the bloodstream.

The diverse mechanisms by which galectins can regulate adaptive and innate immune responses

Researchers explored ways galectins can impact immunity and discussed the opportunities and challenges in the field.

Researchers identify a small number of 'cheating' cancer cells under hypoxia

Researchers at UConn Health, Yale, and Johns Hopkins have identified that some cancer cells can "cheat" through escaping constraints imposed by lack of oxygen, allowing the cancer cells to continue to grow.

The biological properties of the SARS-CoV-2 E protein in the context of HIV-1

Researchers assessed the effectiveness of SARS-CoV and SARS-CoV-2 envelope proteins against HIV-1.

What is the impact of SARS-CoV-2 on HIV-1 infectivity?

In a new study, researchers assessed the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and SARS-CoV envelope (E) proteins on human immunodeficiency virus type 1 (HIV-1) infectivity.

Study provides new insights into genetic form of frontotemporal dementia

Dementia encompasses a range of neurodegenerative conditions that lead to memory loss and cognitive deficiencies and affect some 55 million people worldwide.

Swine acute diarrhea syndrome coronavirus promotes replication by inducing autophagy

The swine acute diarrhea syndrome coronavirus promotes autophagy to maintain its replication inside host cells.

Investigating plasma signatures of platelet-derived proteins in acute pulmonary embolism

In a new study, researchers determined plasma signatures of proteins related to or derived from platelets in acute isolated pulmonary embolism (iPE) and deep vein thrombosis-associated PE (DVT-PE), compared to isolated DVT (iDVT).

The effect of ORF3c, a SARS-CoV-2 accessory protein, on cellular innate immune responses, autophagy, and lung cell mitochondrial metabolism

Researchers explored the role of the ORF3c, a SARS-CoV-2 accessory protein not so extensively studied as yet.

Researchers identify a new gene implicated in rare lysosomal storage disorder

In a rare disease called mucolipidosis type II, people’s hearts and abdomens swell, and their bones grow malformed.

Study reveals the role of autophagy in competitive elimination of cancer cells

Elimination of transformed cells that can initiate cancer is necessary to maintain tissue integrity. In a new study, scientists from Tokyo University of Science show how this mechanism is regulated by the cellular process “autophagy.”

Singapore researchers identify protein that transports degraded membrane lipids out of lysosomes

Researchers at Duke-NUS Medical School and colleagues in Singapore have identified a protein that transports degraded membrane lipids out of lysosomes, cellular organelles that are the breakdown factories of cells.

Discovery could resolve one of the mysteries of Parkinson's disease

Aggregates of the protein alpha-synuclein spread in the brains of people with Parkinson's disease through a cellular waste-ejection process, suggests a new study led by Weill Cornell Medicine researchers.

20 Sep 2022

Researchers provide critical insights into the molecular mechanisms underlying lysophagy

Autophagy is a self-degradation process that cells use to remove unneeded or damaged components. There are several forms of autophagy, including macroautophagy, which is a bulk degradation system used to target materials in the cell's cytosol to organelles called lysosomes for enzymatic breakdown.
