Allergies

The term allergy encompasses a wide range of conditions; it is not a disease in itself. The term allergy – medically termed hypersensitivity, signifies an exaggerated reaction to foreign substances.

Old Friends Hypothesis

The "old friends" hypothesis was proposed by Graham Rook in 2003 as an alternative to or refinement of the hygiene hypothesis, originally brought forward by Strachan in 1989 as an explanation for the rise in allergic disease.

Influenza D shows strong potential to spill over to humans

The influenza D virus that researchers say has been flying under the radar since its detection in animals in 2011 can vigorously make copies of itself in human cells and lung tissue samples, a new study shows.

Air quality in infancy may fundamentally shape long-term immune development

Ambient air pollution is associated with respiratory infection burden in the first year of life, according to preliminary findings from the Immune Development in Early Life (IDEaL) Rome Cohort. Findings from the cohort will be presented during the Pediatric Academic Societies (PAS) 2026 Meeting, taking place April 24-27 in Boston.

Washington’s hepatitis C elimination initiative improves treatment access, reduces costs

It took less than 22 years after the discovery of the hepatitis C virus (HCV) for a fast-acting, highly effective treatment to become available.

New mechanism disables antibiotic resistance and cross-protection in bacteria

A newly discovered mechanism renders antibiotic-resistant bacteria vulnerable by disabling both their individual resistance and a process known as cross-protection, the ability of resistant bacteria to shield nearby, otherwise sensitive strains.

When rice-based formula is the right choice for cow’s milk allergy

This expert-driven framework aids clinicians in selecting hydrolyzed rice formula for infants with cow's milk allergy, enhancing dietary management strategies.

New flu vaccine approach targets multiple virus strains

Doctors recommend getting your flu shot annually, since the specific influenza strain it targets varies from year to year. But what if the shot could be more effective while protecting against more strains?

Nanodisc technology improves study of viral proteins for vaccines

Viruses are masters at invading our cells thanks to specialized proteins that coat their surfaces. When scientists design vaccines, they often create versions of these viral surface proteins to study how our immune systems might respond.

Novel mucosal vaccine offers broad protection against diverse influenza viruses

A novel vaccine platform has been developed to induce broad, protective immunity against numerous influenza virus infections, showing promise as an effective mucosal vaccine strategy, according to a study published by researchers in the Institute for Biomedical Sciences at Georgia State University.

How the nutrient cysteine controls cancer-fighting power of T cells

A research team from the Johns Hopkins Kimmel Cancer Center, its Bloomberg~Kimmel Institute for Cancer Immunotherapy and the Johns Hopkins Bloomberg School of Public Health have discovered how the immune system's CD8+ T cells use the nutrient cysteine to control two essential functions that compete for this resource - the immune cell's ability to multiply and its ability to kill cancer cells.

Ticks can survive for up to three weeks inside homes

It's fairly common for members of the public to ask bug experts if ticks that hitchhike into a house on people or dogs can actually survive indoors for any length of time.

Blocking fructose metabolism may improve brain tumor immunotherapy response

Northwestern Medicine scientists have discovered that specialized immune cells within the glioblastoma tumor metabolize fructose to suppress immune responses and promote tumor growth, reports a study published on March 17 in the Proceedings of the National Academy of Sciences.

Targeting two influenza proteins may reduce viral transmission

A long-running debate in vaccine design revolves around whether a vaccine should be optimized to prevent the virus from replicating inside an infected host or prevent the virus from transmitting to others.

Study finds cockroach allergy often driven by shared proteins across arthropods

Researchers analyzed molecular sensitization patterns in Polish patients with perennial allergic rhinitis who tested positive for cockroach allergens. They found that most apparent cockroach allergies were driven by cross-reactive proteins shared with mites, seafood, and other arthropods rather than true cockroach-specific allergens.

Scientists uncover how the immune system actively builds food tolerance

Food allergies are serious and, for some, potentially deadly. And yet, despite decades of research into allergies and what causes them, very little is known about why the vast majority of people are able to tolerate foods that can sicken or even kill others.
