Insect bites or stings, like the one on this person’s hand, are a manifestation of inflammation.

Inflammation is a complicated and important part of how the immune system responds to threats to the body. But when the inflammatory response goes awry, it can lead to serious problems.
Rheumatoid arthritis leads to painful joint inflammation, often in the hands and wrists.

A new species of bacteria that doesn’t normally live in the gut may trigger an immune response so strong that it spreads to the joints.
Heavy metals can be toxic to plants - and humans, too.
Plants have evolved several ways to deal with heavy metals that might otherwise poison or kill them.
A new theory of Alzheimer’s disease reassesses the role of beta-amyloid in the brain.

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.
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.
Bacteria can team up with viruses to cause coinfections.

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.
New remedies are needed as rates of multi-drug resistant TB rise.
As antibiotics lose their power to treat some forms of TB, interest in the antibacterial powers of curdlan is rising.
The appearance of hives can vary with skin color.

Hives are an allergic reaction and can sometimes be a sign of a more serious immune response.
The immune system usually stays dormant in the lungs in times of health.

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.
Consuming an ample supply of fresh fruits and vegetables is still a tried and true way of getting vitamins and minerals and achieving lasting health benefits.

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.
Immunosenescence, or immune aging, can lead to less effective responses to vaccines and greater vulnerability to invading pathogens.

While the immune system naturally gets weaker with age, social stressors like trauma and discrimination can hasten immunosenescence.
With mask mandates and vaccine requirements lifting, public health information remains crucial so people can weigh their own COVID-19 risks.

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.
Seven nasal vaccines for COVID-19 are currently in clinical trials around the world.

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.
MS is an autoimmune disease in which elements of the immune system begin to damage the brain and spinal cord.
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.
The stress of exercising while sick could potentially make our immune cells less effective.

As little as 30 minutes of exercise five times a week can benefit your immune system.
Viewing immunity as a carpet that we weave together evokes labour and artistry, and suggests we have a role in crafting something rather than simply being acted upon by a virus.
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.
Immunologists are studying how the SARS-CoV-2 virus interacts with antibodies in the immune system.

COVID-19 has taken away so much. An immunology researcher describes the good it may leave behind.

Nucleic acid vaccines use mRNA to give cells instructions on how to produce a desired protein.

DNA and mRNA vaccines produce a different kind of immune response than traditional vaccines, allowing researchers to tackle some previously unsolvable problems in medicine.
