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.

Silica nanoparticles dampen early allergy signals in mouse mast cells

This in vitro study found that negatively charged SiO2 nanoparticles suppressed antigen-induced degranulation and activation-marker changes in IgE-sensitized mouse bone marrow-derived mast cells. By contrast, mTiO2 nanoparticles showed cytotoxic and pro-inflammatory effects, including enhanced DNP-induced IL-6 release, suggesting nanoparticle composition can shape early allergic immune responses.
