Alzheimer’s may not be primarily a disease of the brain. It may be a disorder of the immune system within the brain. Beta-amyloid may not be an abnormal protein, but part of the brain’s immune system.
Evidence is growing there are changes to your immune system that may put you at risk of other infectious diseases.
Ant feet are equipped with an array of tools – from retractable sticky pads to claws to special spines and hairs – enabling them to defy gravity and grip virtually any surface.
Exposure to diverse microbes boosts our immunity, while spending time in nature restores wellbeing. And COVID reminds us of the risks of new viruses when we intrude on and degrade natural habitats.
Coinfections with bacteria can make viral infections even deadlier. Researchers have identified a protein in immune cells that may play a role in fighting both types of pathogens.
As antibiotics lose their power to treat some forms of TB, interest in the antibacterial powers of curdlan is rising.
Hives are an allergic reaction and can sometimes be a sign of a more serious immune response.
While a strong immune response is essential to fight against viral infection, an immune system that continues to stay active long after the virus has been cleared can lead to lung damage.
Despite the popular belief that vitamin E and beta carotene supplements help prevent heart disease and cancer, the latest research suggests they do not – but the supplements do have potential risks.
While the immune system naturally gets weaker with age, social stressors like trauma and discrimination can hasten immunosenescence.
To help people make informed decisions about ongoing COVID-19 risks, public health messaging needs to adapt as the pandemic evolves, just as immune systems adapt to new viruses and variants.
Research suggests that giving a person a vaccine through their nose can provide a better defense against future exposure to the coronavirus compared to a shot in the arm.
The causes of multiple sclerosis (MS) are complex, but recent research found Epstein Barr virus, the same virus that causes mononucleosis, is an environmental trigger for MS.
As little as 30 minutes of exercise five times a week can benefit your immune system.
The metaphor of a collective “carpet of immunity” invites us to imagine immunity as a collaborative project, spreading out to protect those for whom the end of mandates means increased vulnerability.
COVID-19 has taken away so much. An immunology researcher describes the good it may leave behind.
The drug pembrolizumab reveals where latent HIV is hiding.
DNA and mRNA vaccines produce a different kind of immune response than traditional vaccines, allowing researchers to tackle some previously unsolvable problems in medicine.
Remorse and sorrow from a bad choice can haunt you for years, even decades. But there are evidence-based ways to move past regret.
