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.

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.

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.

New peptide fragments teach the gut to tolerate food

In little moments like when sipping coffee or licking an ice cream cone, it doesn't seem like your body is pulling off a biological miracle. But it is. That cookie is not you-yet when you put it in your mouth, your body is able to tolerate it and process it without any detriment to your health in a process called oral tolerance. How does the human body make that decision between tolerance and rejection?

Melbourne’s lab-grown "skin" revolutionizes tick research

The world's first lab-based tick feeding system for bush ticks, developed by researchers at the University of Melbourne, has transformed the study of ticks and how they transmit disease. The novel, host-free technology reduces the need for animal experiments in tick studies, facilitating more ethical, reproducible research.
