Learning a language or recognizing music is usually a breeze for children, however, this capacity dramatically declines with age. Now, a study from researchers at St. Jude Children’s Research Hospital … Continue Reading Controlling a single brain chemical expands the window for learning language and music in an animal model.
Stress is the feeling of being under acute mental or emotional pressure, where a person may feel unable to cope, leading to a wide variety of health problems. When stress … Continue Reading Neuroimaging connects stress-associated brain activity to cardiovascular disease in humans.
Cell ablation is an important tool for selectively destroying one or multiple cells in a given organism to remove a disease such as cancer or to produce the desired response … Continue Reading Researchers successfully eliminate neurons outside the brain to trigger obesity.
Welcome to The Top Ten Healthinnovations of 2016, the third-year in our successful series, where the most exciting discoveries and breakthroughs are decided by you, the global medical community. This … Continue Reading The Top Ten Healthinnovations of 2016.
When it comes to hearing, precision is important say researchers. Due to the fact vertebrates, such as birds and humans, have two ears, and sound-waves from either side travel different … Continue Reading Researchers map auditory brain cells for maximum hearing precision.
Alcoholism is a chronic relapsing disorder associated with compulsive drinking, loss of control over intake, and emergence of a negative emotional state during abstinence from the drug. Special emphasis has … Continue Reading Researchers target neurons involved in compulsive drinking to reverse alcohol dependence in rats.
Zika virus is a mosquito-transmitted flavivirus that is closely related to Dengue, West Nile, and yellow fever viruses. Zika virus causes mild disease in most adults and can cause brain … Continue Reading Evidence of Zika virus found in tears, may persist in eyes.
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.
Generally, researchers divide the human immune system into two parts. One part, called the innate immune system, allows for immediate and direct recognition of invading bacteria. It prompts immune cells … Continue Reading Study identifies previously unknown mechanism of the immune system.
Patients suffering from so-called immune-mediated neuropathies frequently have a long medical record. As there are no diagnostic tests available to reliably diagnose the disease, the diagnosis is frequently made belatedly … Continue Reading Study identifies previously unknown cause of immune neuropathy.
Acute HIV-1 infection is the phase of HIV-1 disease immediately after infection that is characterized by an initial burst of viremia; although anti-HIV-1 antibodies are undetectable, HIV-1 RNA or p24 … Continue Reading Study captures HIV study early to successfully characterise the elusive acute infection period.
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.
Neurodegeneration in Alzheimer’s disease is thought to be caused by the abnormal behavior of amyloid-beta molecules, which are known to gather into tough fibril-like structures called amyloid plaques within patients’ … Continue Reading Human amyloid-beta shown to act as a powerful antibiotic in the brains of animal models.
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.
The intestines’ primary role is digestion, however, they must also achieve high performance around the clock defending against pathogens and environmental pollutants. This is because everything taken up with food … Continue Reading Study shows how an important intestinal immune response controller works.
