Our onboard computer, the brain, is a sterile environment separated from the immune system by the blood-brain barrier (BBB), which is why it has its own resident immune cells, known … Continue Reading New role for white blood cells in the developing brain.
Red blood cells (RBCs) are described as our very own shipping system, transporting oxygen from the lungs to the body’s tissues. Biological RBCs are extremely flexible, squeezing through tiny spaces … Continue Reading Synthetic red blood cells mimic natural ones, possess multiple applications.
Policing what goes in and out of the body, the immune system is a line of defense guarding against infection whilst distinguishing foreign bodies from the person’s healthy tissue. One … Continue Reading Previously unknown human immune cell discovered.
A devastating disease, childhood leukemia, the most prevalent type of cancer in children and teens, is a cancer of the body’s immune cells, also known as white blood cells. Abnormal … Continue Reading Human immune cells in-a-dish produced in world’s first.
When exposed to cold, clusters of cells within the body’s white fat become beige, a colour change which reflects the creation of more energy-producing mitochondria, cellular components that enable cells … Continue Reading Study shows that fat cells which amplify nerve signals in response to cold also affect blood sugar.
When the body is fighting an invading pathogen, white blood cells, including T cells, must respond. T-cell receptors (TCRs) recognize pathogens during T-cell–mediated adaptive immune responses. The binding between TCRs … Continue Reading New imaging provides unprecedented detail of immune cells’ surface.
The body has an army of millions of immune cells. These cells contain receptors generated through random genetic rearrangements, a clever strategy to keep them ready to fight unfamiliar viruses … Continue Reading Previously unknown immune cell identified, with implications for T1 diabetes.
It is known that natural killer cells, a type of white blood cell prevalent in the body, deliver lethal toxic granules into cells that have become cancerous or infected, causing … Continue Reading Identification of master regulator for specialised immune cell raises hope in cancer fight.
It is known that HIV, the causative agent of AIDS, is severely species restricted, and, to date, only humans and chimpanzees have been shown to be susceptible to infection. Human … Continue Reading First-ever study proves HIV targets & replicates in human macrophages.
Prostate cancer is the development of cancer in the prostate, a gland in the male reproductive system. Most often, prostate cancer spreads to the bones and also to the liver … Continue Reading Nanoparticles hitchhike on whiteblood cells to kill tumour cells in bloodstream.
As a part of the human immune system, white blood cells create a number of enzymes that help fight disease. Sometimes, these enzymes can malfunction, causing damage to the body … Continue Reading Study sheds light on cancer-spreading enzymes produced by the immune-system.
A mammals’ body temperature is usually constant, however, when exposed to cold their body temperature drops by few degrees before slowly rising almost back to normal. This adaptive mechanism is … Continue Reading Study shows how gut microbiota regulates weight loss & good fat in the cold.
The primary role of monocytes is to sense the environment and replenish the pool of tissue macrophages and dendritic cells. Recent advances in immunology research have discovered that monocytes can … Continue Reading Role finally identified for subset of white blood cells in cancer metastasis.
All mammals, including humans, have two types of fat with completely opposite functions. These are white fat, which stores energy and is linked with diabetes and obesity; and brown fat, … Continue Reading Researchers identify epigenetic switch which generates calorie-burning brown fat.
Approximately 28 million Americans live with Type 2 diabetes, a condition characterized by high blood sugar levels. The immune system plays a part in type 2 diabetes. Researchers have linked … Continue Reading Decades old mystery solved as researchers map the effect of T2 diabetes on the lymphatic vessels.
Women who experience more hot flashes, particularly while sleeping, during the menopause transition are more likely to have brain changes reflecting a higher risk for cerebrovascular disease, such as stroke … Continue Reading Frequent overnight menopausal hot flashes linked with brain scan changes.
