Cell signaling is vital for cells to communicate and coordinate their activities, not just in the human body, but in all organisms. There are thousands of signaling pathways, ranging from protein homeostasis to carcinogenesis and biofilm formation.

New biomarker may help identify patients at risk for graft-versus-host disease after stem cell transplants

A recent report published in Science Translational Medicine by MUSC Hollings Cancer Center investigator Sophie Paczesny, M.D., Ph.D., sheds light on immune cell biomarkers that may reveal which patients are most at risk for graft-versus-host disease (GVHD), a life-threatening condition that can arise after hematopoietic stem cell transplantation (HSCT) for treatment of liquid cancers such as leukemia.

Study reveals complex immunology behind MIS-C in children with COVID-19

In a recent paper published in the prestigious journal Cell, researchers from Sweden and Italy show that inflammatory response in Multisystem Inflammatory Syndrome in Children associated with coronavirus disease (COVID-19) differs from the cytokine storm found in severe acute illness, involving autoantibodies at the same time and sharing several features with Kawasaki disease.

Brain estrogen critical for astrocyte activation and neuroprotection

When the brain isn't getting enough oxygen, estrogen produced by neurons in both males and females hyperactivates another brain cell type called astrocytes to step up their usual support and protect brain function.

Study offers hope for treatment of Krabbe disease

In one out of 100,000 infants, a mutation in the GALC gene causes an incurable, always fatal disorder known as infantile Krabbe disease, or globoid cell leukodystrophy. Most children with the condition die before they turn 2.

SARS-CoV-2 ORF9c responsible for immune evasion and efficient infection of host

A recent study by researchers at the Sanford Burnham Prebys Medical Discovery Institute and the University of California San Francisco and published on the preprint server bioRxiv in August 2020 shows that a protein encoded by the subgenomic sequence ORF9c of SARS-CoV-2 is responsible for the low antiviral response in infected humans, enabling the successful replication of the virus in the host.

Bioinformatics identifies key genes and cellular pathways in COVID-19

The COVID-19 pandemic is showing no signs of waning or extinction anytime soon. Now, a new study published on the preprint server bioRxiv* in August 2020 shows a new bioinformatics approach to studying the pathogenesis of this disease, by uncovering the differentially expressed genes (DEGs) and cell signaling pathways that cause the disease characteristics. This will help develop better therapies to counter the effects of these genes.

Researchers identify new treatment for osteoarthritis

The study results revolve around the long-established idea that machines within animal and human cells turn the sugars, fats, and proteins we eat into energy used by the body's millions of cells.

Study sheds light on potential new treatment approach in AML patients

Tyrosine kinases are protein enzymes that have many functions within cells, including cell signaling, growth, and division. Sometimes these enzymes can be overactive, which helps cancer cells survive and multiply.
