A protein in Salmonella inactivates mast cells- critical players in the body’s fight against bacteria and other pathogens- rendering them unable to protect against bacterial spread in the body, according to researchers.
Researchers have determined the structure of the rubella virus capsid protein, which is central...
A protein called Tet1 is partly responsible for giving primordial germ cells a clean epigenetic...
Scientists have determined the most detailed picture yet of a crucial part of the hepatitis C virus, which the virus uses to infect liver cells. The new data reveal unexpected structural features of this protein and should greatly speed efforts to make an effective hepatitis C vaccine.
Researchers have shown that tiny quantities of the protein tau can be enough to kick-start an aggregation process which may explain the onset of Alzheimer’s in the brain.
Investigators have accomplished an important step toward their goal of creating primitive synthetic cells. The “protocells” they are building consist of a nucleic acid strand encased within a membrane-bound compartment.
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
A research team has identified an immune cell protein that is critical to setting off the body’s initial response against viral infection.
Using a new method to catch elusive “jumping genes” in the act, researchers have found two human proteins that are used by one type of DNA to replicate itself and move from place to place.
Researchers have recently developed a new technique for profiling enzyme activities in cell lysate, a fluid containing the internal contents of cells, allowing them to analyze the enzyme reactions within cells.
The protein in cells that most often drives the development of cancers has eluded scientists’ efforts to block it for three decades– until now.
A research team has found that a specific chemical compound, an aldehyde, can activate UCP1, a protein known as UCP1 that enables babies or hibernating animals to keep warm without shivering, under certain conditions, and that could also trigger fat burning.
Researchers have now solved the structure of a key protein in the Nipah virus, which could pave the way for the development of a much-needed antiviral drug.
Scientists have solved a long-standing conundrum about the immune system and in so doing may have found a new way to boost or reduce immunity therapeutically.
A protein engineered by combining proteins active in HIV and Moloney murine leukemia virus (MLV) replication may lead to safer, more effective retroviral gene therapy.
New research using tissue from the Parkinson's UK Brain Bank suggests that a protein called alpha-synuclein causes the spread of nerve cell death in multiple system atrophy (MSA), a Parkinson's-like condition.
A study new study found that an enzyme that edits RNA may loosen the genome’s control over invasive snippets of DNA that affect how genes are expressed. In fruit flies, that newly understood mechanism appears to contribute to differences among individuals such as eye color and life span.
Two groups of scientists have made complementary discoveries that break new ground on efforts to turn back the body’s clock on cellular activity, paving the way for a better understanding of stem cells, tissue growth and regeneration.
Scientists have demonstrated that that cancer cells need a protein called Bod1 to grow and divide. When this protein is removed, cancer cells lose control of cell division and die.
Imagine a 1950s horror movie monster— a creeping, gelatinous, gluey tangle of gunk that strangles everything around it. That’s what amyloid plaques are like when they form in body tissues.
A new study clarifies the role of calcium signaling in the medically significant communication between skin cells that occurs during wound healing.
Using cells from the stem of a seedling as a model system, biologists are seeking to understand the molecular mechanisms that organize and pattern the hundreds or thousands of microtubular “bones” of the plant cytoskeleton.
Cell biologists have teased apart two integral components of the machinery that causes cells to move. Their discovery shows that cellular projections, which act as hands to help a cell "crawl," are apparently always initiated by a network of message-relaying proteins inside the cell.
A colorful wheel developed bioengineers to visualize protein interactions has won an international competition for novel strategies to study the roots of breast cancer.
The formation of long-term memory is dependent on protein synthesis at a specific location and time in brain tissues. A research team recently developed a new imaging technique to pinpoint exactly where and when cells produce new proteins.
A group of researchers and students has developed a new Web program that will help scientists visually analyze DNA and protein sequence patterns faster and more efficiently than ever before.
A protein increased by endurance exercise has been isolated and given to non-exercising mice, turning on genes that promote brain health and encourage the growth of new nerves involved in learning and memory, researchers say.
Often deadly “triple-negative” breast cancers might be effectively treated in many cases with a drug that targets a previously unknown vulnerability in the tumors, according to a new study. Researchers found blocking cystine from entering triple-negative breast cancer cells can significantly inhibited their growth in culture and when the cancer cells were transplanted into mice.
