Immunosuppression in COVID-19 promotes emergence of multiple immune escape mutants

An interesting new study describes the emergence of several such variants from a chronically immunosuppressed COVID-19 patient, who remained infected for over 170 days before clearing the virus.

Are infants at greater risk of COVID-19 than children?

The widely circulating SARS-CoV-2 has caused the devastating COVID-19 pandemic. The impact of this infection varies significantly with age, sparing young children for the most part, though not completely. However, a new study, released as a preprint on the medRxiv* server, shows that infants are not as resistant to the virus as children are. The researchers trace this to the expression of ACE2 to varying extents in different groups.

Human organoids useful for modeling COVID-19 variants of concern, finds study

A new study published on the bioRxiv* preprint server found that using human organoids could help with better characterizing the phenotype of several viral variants, including B.1.1.7. Their findings show the ribonucleic acid (RNA) shedding of the SARS-CoV-2 variant correlated with viral fitness and infectiousness.

High-throughput system can regulate gene expression for treating sickle cell disease, beta thalassemia

St. Jude Children's Research Hospital scientists have developed an integrated, high-throughput system to better understand and possibly manipulate gene expression for treatment of disorders such as sickle cell disease and beta thalassemia. The research appears today in the journal Nature Genetics.

Scientists investigate signal necrotic cells that cue phagocytic cells to engulf the dying cell

Just as people keep their houses clean and clutter under control, a crew of cells in the body is in charge of clearing the waste the body generates, including dying cells. The housekeeping cells remove unwanted material by a process called phagocytosis, which literally means 'eating cells.' The housekeepers engulf and ingest the dying cells and break them down to effectively eliminate them.

Researchers report encouraging results from experimental antiviral targeting Marburg virus

The Marburg virus, a relative of the Ebola virus, causes a serious, often-fatal hemorrhagic fever. Transmitted by the African fruit bat and by direct human-to-human contact, Marburg virus disease currently has no approved vaccine or antivirals to prevent or treat it.

Researchers describe the key facet of sexual determination in mammalian models

Early in human development, during the first trimester of gestation, a fetus may have XX or XY chromosomes that indicate its sex. Yet at this stage a mass of cells known as the bipotential gonad that ultimately develops into either ovaries or testes has yet to commit to its final destiny.

Highly efficient immune response in asymptomatic SARS-CoV-2 patients

Researchers in Singapore have investigated the role of SARS-CoV-2-specific antibodies and T-cells in asymptomatic individuals suffering from COVID-19. They found that, contrary to some initial hypotheses, asymptomatic individuals mount an adaptive immune response on par with symptomatic individuals, demonstrating that T cell response does not appear to be correlated with symptom severity.

Researchers discover new binding sites for active agents on cell cytoskeleton

Through a unique combination of computer simulations and laboratory experiments, researchers at the Paul Scherrer Institute PSI have discovered new binding sites for active agents - against cancer, for example - on a vital protein of the cell cytoskeleton. Eleven of the sites hadn't been known before. The study appears today in the journal Angewandte Chemie International Edition.

Molecular clues explain why some neurons are more susceptible than others in Alzheimer’s disease

In the brain of a person with Alzheimer's disease, neurons degenerate and die, slowly eliminating memories and cognitive skills. However, not all neurons are impacted equally.

New transport system delivers large protein-based drugs into cancer cells

The ability of antibodies to recognize specific cancer cells is used in oncology to specifically target those cells with small active agents.

SARS-CoV-2 infection prolongs viral shedding and lymphocyte loss in patients with cancer

Patients with cancer have a more challenging time with infections while undergoing treatment — placing them as high-risk for severe COVID-19 illness and death. However, how the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) interacts with cancer therapies remains poorly understood.

A single archaeal enzyme can produce a spectacular range of natural and non-natural cardiolipins

Cells of all life forms are surrounded by a membrane that is made of phospholipids. One of these are the cardiolipins, which form a separate class due to their unique structure.

A new method for producing faster and more efficient vaccines

Vaccines are currently a great source of hope for many people, as it is believed they will help to protect society against COVID-19 and pave the way back to a normal life. The current focus is clearly on coronavirus — but vaccines are also fundamental to combating other pathogens.

Cryptic pocket on the surface of SARS-CoV-2 may be a promising treatment target

In a new study currently available on the bioRxiv* preprint server, a multinational group of researchers modeled an entire membrane-embedded spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and highlighted the potential of a specific mapping approach for unveiling cryptic, potentially druggable pockets on the viral surface.

New strategy could increase the effectiveness of chemotherapy treatments

New research led by a team at Massachusetts General Hospital (MGH) points to a promising strategy to boost tumors' intake of cancer drugs, thereby increasing the effectiveness of chemotherapy treatments.

Study reports vitamin C inhibits SARS-CoV-2 virus main protease

Based on structural analysis, researchers found that vitamin C binds to 3CLpro, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease essential in viral replication. In vitro cell inhibition studies also showed vitamin C could inhibit 3CLpro, indicating a possible new antiviral treatment method.

Indian SARS-CoV-2 variant shows enhanced host cell entry and immune evasion

A study conducted by researchers in Germany has found that the B.1.617 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that has emerged in India entered certain types of lung and intestine cells with slightly increased efficiency compared with the original wild-type strain.

New technique can print life-like organ models in minutes

NIBIB-funded engineers at the University of Buffalo have fine-tuned the use of stereolithography for 3D printing of organ models that contain live cells.

Advanced-stage kidney cancer more common in Hispanic and Native Americans in Arizona

Recently published research from the University of Arizona Health Sciences shows that advanced-stage kidney cancer is more common in Hispanic Americans and Native Americans than in non-Hispanic whites, and that both Hispanic Americans and Native Americans in Arizona have an increased risk of mortality from the disease.
