Scientists modify toxic pesticide to treat antibiotic-resistant bacteria

A significant class of heterocyclic compounds, called N-Aryl-C-nitroazoles, is used as fungicides and pesticides. But these substances could be harmful to human beings and cause mutations.

Gut cells raise alarm during parasite invasion

To effectively combat an infection, the body first has to sense it's been invaded, then the affected tissue must send out signals to corral resources to fight the intruder.

Transporter protein likely played a crucial role in vertebrate evolution

A transporter protein that regulates cell membrane cholesterol likely played an important role in vertebrate evolution, according to a review published by iCeMS researchers in the journal FEBS Letters.

Study reveals lower transfer of protective SARS-CoV-2 antibodies via the placenta

Recent analyses indicate that pregnant women and newborns may face elevated risks of developing more severe cases of COVID-19 following SARS-CoV-2 infection.

Scientists observe detailed images of spike proteins in coronavirus

Coronaviruses, similar to the one that causes COVID-19 infection, are embedded with protein “spikes” that attach to receptors on their victims’ cells.

New study targets small proteins in Salmonella to combat the pathogen

Salmonella is a type of bacteria that causes food poisoning upon infection, with acute diarrhea.

Researchers identify suitable biocatalyst for designing COVID-19 vaccine

The chemical substance class of nucleosides is attracting a great deal of interest, and this can be attributed to the ongoing COVID 19 pandemic.

Gene expression database sheds light on pneumococcal infection

Researchers at the University of Maryland School of Medicine published one of the most comprehensive analyses of how genes get expressed during infection (known as a transcriptome).

Biochemical methods reveal signal transduction mystery inside human pathogen

In order to adapt to the changing environment, bacteria must quickly transform extracellular information into appropriate intracellular reactions. Two component system (TCS) is the main signal transduction protein in prokaryotic cells to transform environmental stimuli into cellular responses.

New antibiotic can help treat drug-resistant pathogens

Researchers from Johns Hopkins University and Medicine have designed a potential new antibiotic for a pathogen that is highly resistant to drugs and is often lethal to individuals suffering from lung diseases, including cystic fibrosis.

A genetic shortcut to help visualize proteins at work

A group at Gladstone Institutes and UC San Francisco (UCSF) has demonstrated that a large-scale and systematic genetic approach can indeed yield reliable and detailed information on the structure of protein complexes.

New portable optical sensor can monitor plant stress

The portable device allows rapid detection of nitrogen deficiency - a critical nutrient for plant health. When tested on popular vegetables such as Spinach and Kai-Lan, the device was also able to detect levels of other metabolites; allowing measurement of a wider range of plant stress phenotypes such as drought, heat/cold, saline, and light stress.

Toxic pollutants may be influencing wildlife disease spread, finds study

Exposure to toxic pollutants associated with human activities may be influencing the spread of infectious diseases in wildlife, according to a new study from the University of Georgia.

Study provides new insight on how lung bacteria protect against invading pathogens

New insight on how bacteria in the lungs protect against invading pathogens has been published today in the open-access eLife journal.

Researchers discover molecular mechanism of plant immune receptors

In a recent study, Alexander von Humboldt Professor Jijie Chai at the University of Cologne and his team together with MPIPZ researchers have succeeded for the first time in reconstructing the sequence of molecular events that activate an inactive plant immune receptor and thus mediate the death of the host cell.

Gasdermin E triggers pyroptosis and involved in pathogen-induced coral death

Pyroptosis is a highly inflammatory form of programmed necrotic cell death that acts as a defense mechanism against the infection of bacterial and viral pathogens. Pyroptosis is executed by gasdermin, a family of pore-forming proteins.

Researchers design living plant-based sensor to track arsenic levels

For the first time, researchers from SMART have engineered a living plant-based sensor for the detection of arsenic in the belowground environment

Specific immune mechanism in COVID-19 patients triggers inflammatory process

Researchers at the University of São Paulo (USP) in Brazil have demonstrated for the first time that in COVID-19 patients an immune mechanism known as the inflammasome participates in activation of the inflammatory process that can damage several organs and even lead to death.

Study shows metabolic state of disease-causing parasite influences its resistance to drugs

A new study has revealed how a disease-causing parasite is able to resist the present range of therapies. The study was recently published in eLife.
