Viral RNA undergoes conformational changes to hijack host cells, says study

Scientists from the University of Colorado Anschutz Medical Campus recently identified how an RNA molecule from a virus develops a complex, three-dimensional structure, and is capable of changing its shape to hijack host proteins.

Research could help understand DCIR's role in the pathogenesis of autoimmune diseases

While dendritic cell immunoreceptor (DCIR) is known to mediate inflammation and bone metabolism, ligands that bind DCIR and the mechanisms underlying DCIR activity remain poorly understood.

Researchers develop a new way of simulating cell mechanics

Researchers from The University of Texas at Arlington are working to create a simulation technique that better predicts how stem cells develop into specific cells, such as bone or skin.

UD biochemist explores how mRNA eraser enzymes work in our cells

University of Delaware biochemist Jeff Mugridge is trying to figure out how so-called mRNA eraser enzymes work in our cells, why those erasers can sometimes misbehave and lead to cancer, and how science can pave the way for possible solutions to this problem.

Study shows why disruption of the body clock leads to inflammatory diseases

New research from RCSI has demonstrated the significant role that an irregular body clock plays in driving inflammation in the body's immune cells, with implications for the most serious and prevalent diseases in humans.

Persistency allows value signals to be most effectively coded across different brain areas

In 2019 University of California San Diego researchers discovered the area of the brain where "value decisions" are made.

Dopamine may play a key role in shaping female songbirds' auditory preference

In humans, the dopamine system has been tied to rewards and pleasurable sensations. As well as to memory and learning.

Researchers discover molecular mechanism that explains why moles become melanomas

Moles and melanomas are both skin tumors that come from the same cell called melanocytes. The difference is that moles are usually harmless, while melanomas are cancerous and often deadly without treatment.

New details about Shigella's translocon may help develop effective strategy to block infection

Shigella, a bacterial pathogen that causes dysentery and is the leading cause of childhood diarrheal diseases, inserts a pore called a translocon into an infected person's intestinal cells and then injects bacterial proteins into the cells.

Researchers expand understanding of how T cells recognize infections or disease

T cells communicate with other cells in the body in search of infections or diseases. This crosstalk relies on specialized receptors known as T cell receptors that recognize foreign molecular fragments from an infection or cancer that are presented for detection by particular molecules called major histocompatibility complex (MHC) or MHC-like.

Scientists develop advanced imaging technique to analyze oxygenation within bone tissue

Without doubt, the future of life sciences is sure to have technology that can measure biological parameters real-time in living organisms.

MIT researchers identify a way to indirectly activate T cells to fight tumors

Under the right circumstances, the body's T cells can detect and destroy cancer cells. However, in most cancer patients, T cells become disarmed once they enter the environment surrounding a tumor.

Researchers develop artificial genomic DNA capable of replication and evolution

Professor Norikazu Ichihashi and his colleagues at the University of Tokyo have successfully induced gene expression from a DNA, characteristic of all life, and evolution through continuous replication extracellularly using cell-free materials alone, such as nucleic acids and proteins for the first time.
