Hypertension is a leading risk factor for dementia, however, the mechanisms underlying its damaging effects on the brain are poorly understood. Now, a study from researchers at Weill Cornell Medicine … Continue Reading Immune cells identified as the culprit linking hypertension and dementia.
Previously unknown immune cell identified, which protects against lung infections during chemotherapy.
It is known that chemotherapy drugs kill dividing cells, including cells in the bone marrow that give rise to different immune cells. However, this can lead to a dramatic reduction … Continue Reading Previously unknown immune cell identified, which protects against lung infections during chemotherapy.
The inflammatory response is an integral part of the innate immune mechanism that is triggered in response to a real or perceived threat to tissue homeostasis, with a primary aim … Continue Reading New class of molecule identified in central role of inflammation and the immune system.
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.
HIV, is a virus that attacks the body’s immune system. If left untreated, HIV can progress and develop into AIDS. HIV infection is enhanced by adhesive structures that form between … Continue Reading First-ever study captures HIV cell-to-cell transmission in a living animal.
Natural killer (NK) cells are bone marrow–derived granular lymphocytes that have a key role in immune defense against viral and bacterial infections and malignancies. NK cells are traditionally defined as … Continue Reading Study shows that natural killer cells have a memory.
A person’s genetic makeup plays a role in autoimmune diseases such as multiple sclerosis that develop when the body is attacked by its own immune system. However, little is known … Continue Reading Study maps gene variants to DNA regions that regulate immune cells.
T cells are the immune cells responsible for recognizing and destroying specific invaders, such as viruses, bacteria, or cancer. Their activity is highly tunable, with signals from other cells adjusting … Continue Reading Study identifies a new regulator of immune responses.
Multiple Sclerosis (MS) is a neurological disease, characterised by demyelination and the onset of chronic, neurodegenerative damage of the central nervous system. Right now, its causes are unknown although various … Continue Reading Researchers identify a new gene involved in Multiple Sclerosis.
Systemic lupus erythematosus (SLE) is a common autoimmune disorder in which the body’s immune system mistakenly attacks healthy tissues, it can affect the skin, joints, kidneys, brain, and other organs. … Continue Reading Study shows how mitochondria drives autoimmune response in lupus.
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.
Macrophages, also known as scavenger cells, are immune cells which are part of the innate immune system and differentiate from monocytes. They circulate in the bloodstream and upon differentiation, invade … Continue Reading New study refutes textbook theory on macrophage metabolism.
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.
Biomimicry or biomimetics is an approach to innovation that seeks sustainable solutions to human challenges by emulating nature’s time-tested patterns and strategies. The goal is to create products and processes … Continue Reading New biomimetic nanoparticle successfully treats eye cancer in animal model.
The peripheral nervous system is a vast network of nerves that exists primarily outside of brain and spinal cord and connects to the far reaches of the body. The very … Continue Reading Study shows how protein promotes regeneration of injured peripheral nerves.
