Duke researchers identify chlamydia’s stealthy cloaking device

Chlamydia, the leading cause of sexually transmitted bacterial infections, evades detection and elimination inside human cells by use of a cloaking device. But Duke University researchers have grasped the hem of that invisibility cloak and now hope they can pull it apart.

New study in mice shows alternate origins of plaques in Alzheimer’s disease

A breakdown in how brain cells rid themselves of waste precedes the buildup of debris-filled plaques known to occur in Alzheimer's disease, a new study in mice shows.

Antiviral potential of N-acylethanolamine acid amide hydrolase against SARS-CoV-2 and Zika virus

A recent study posted to the bioRxiv* pre-print server investigated the antiviral potential of N-acylethanolamine acid amidase (NAAA) against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the Zika virus (ZIKV).

New insights offered into cell-to-cell propagation of SARS-CoV-2

Evidence from a new study supports previous findings showing SARS-CoV-2 particles inside host cells are morphologically identical to those outside of cells.

Famous scientist joins NYU Langone’s Division of Rheumatology

Nationally recognized for his work studying a novel inflammatory disorder known as VEXAS, David B. Beck, MD, PhD, has joined the Division of Rheumatology at NYU Langone.

New study shines light on how plant cells perceive and respond to mechanical forces

Minuscule tunnels through the cell membrane help cells to perceive and respond to mechanical forces, such as pressure or touch. A new study in the journal Science is among the first to directly investigate what one type of these mechanosensitive ion channels is doing in the tip-growing cells in moss and pollen tubes of flowering plants, and how.

Stem cell based cell culture model to recapitulate important aspects of NAFLD

Nonalcoholic fatty liver disease (NAFLD) is a widespread condition in the Western World. Around 30% of the population have lipid droplets stored in their liver which diminish its function in the long term.

Cholesterol in the plasma membrane is essential for SARS-CoV-2 entry and syncytia formation

A preprint indicates that SARS-CoV-2 requires cholesterol to accomplish entry into the host cells and membrane fusion.

SARS-CoV-2 spike protein triggers cell signaling pathways in lung vascular cells

A new study published on the preprint server bioRxiv in October 2020 shows that vascular cells in the lung tissue begin to secrete signaling growth factors when exposed to just the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), without the rest of the viral components.

Genoscience Pharma's GNS561 shows potential against SARS-CoV-2 in vitro

A new study published on the preprint server bioRxiv in October 2020 shows that a combination of a new compound GNS561 and remdesivir act synergistically against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This suggests that autophagy inhibitors could be an alternative strategy for SARS-CoV-2 infection.

New, rare genetic form of dementia discovered

A new, rare genetic form of dementia has been discovered by a team of Penn Medicine researchers. This discovery also sheds light on a new pathway that leads to protein build up in the brain -- which causes this newly discovered disease, as well as related neurodegenerative diseases like Alzheimer's Disease -- that could be targeted for new therapies.

Researchers detect pollution particles in the placentas of UK women

Pollution particles, including metals, have been found in the placentas of fifteen women in London, according to research led by Queen Mary University of London.

Study shows fatty liver disease is a significant risk factor for COVID-19 hospitalization

A recent observational study by US researchers reveals that individuals with non-alcoholic fatty liver disease and steatohepatitis have increased odds of hospitalization due to coronavirus disease (COVID-19); conversely, metabolic surgery was found to be protective against the admission of infected individuals. The study is currently available on the medRxiv* preprint server.

Viable SARS-CoV-2 aerosols detected in a hospital room with COVID-19 patients

Now, a new study by researchers at the University of Florida highlights the role played by SARS-CoV-2 aerosols in disease transmission.

Novel nanospectroscopy measures biomolecular changes induced by drugs in human cells

Synchrotron InfraRed Nanospectroscopy has been used for the first time to measure biomolecular changes induced by a drug (amiodarone) within human cells (macrophages) and localized at 100 nanometre scale, i.e. two orders of magnitude smaller than the IR wavelength used as probe.

Catastrophic macropinocytosis may aid in cancer treatment

In laboratory experiments, a metabolic inhibitor was able to kill a variety of human cancer cells of the skin, breast, lung, cervix and soft tissues through a non-apoptotic route -- catastrophic macropinocytosis.

New strategy could help cells get rid of disease-related debris

Tohoku University researchers have developed a strategy that could help cells get rid of disease-related debris. Further research could lead to treatments for neurodegenerative and metabolic diseases, Down syndrome, and maybe even aging-related diseases.

Blue light and fruit flies: a warning for humans

A new study involving the fruit fly, Drosophila melanogaster, published in the journal npj Aging and Mechanisms of Disease, shows that when flies are kept in darkness, or in white light from which the blue spectrum has been excluded, they live longer, compared to flies kept in alternating 12-hour shifts of blue LED light and darkness. The reason appears to be a speeded-up version of aging; the brain cells, retinal cells and climbing ability, all suffer a breakdown.

Protozoans protect pathogenic bacteria and enhance their infectious potential

Single celled organisms in the environment are protecting pathogenic bacteria and priming them for human infection, an international team of researchers has discovered.
