Osada et al. state that because parasitic worms may and often do consist of allergens themselves, the degree to which they pacify or agitate the immune response against allergens is a balance of their regulating effects and their allergenic components. [11] Therefore, depending on both of these variables, some parasitic worms may worsen allergies.
The idea of a link between parasite infection and immune disorders was first suggested in 1968 [13] before the advent of large scale DNA sequencing techniques.The original formulation of the hygiene hypothesis dates from 1989, when David Strachan proposed that lower incidence of infection in early childhood could be an explanation for the rise in allergic diseases such as asthma and hay fever ...
Pathogen avoidance (also parasite avoidance or pathogen disgust) refers to the theory that the disgust response, in humans, is an adaptive system that guides behavior to avoid infection caused by parasites such as viruses, bacteria, fungi, protozoa, helminth worms, arthropods and social parasites.
They are most often associated with allergy and anaphylaxis. [35] Basophils and eosinophils are related to neutrophils. They secrete chemical mediators that are involved in defending against parasites and play a role in allergic reactions, such as asthma. [39]
An allergy test revealed Liam was allergic to eggs, as well as peanuts and tree nuts, and for the next year, the entire family avoided foods that could trigger a dangerous reaction.
Although this reaction is most well understood in terms of allergy, it appears to have evolved as a defense system against parasites and bacteria. [ 14 ] Mast cells (MCs) have been shown to release their nuclear DNA and subsequently form mast cell extracellular traps (MCETs) comparable to neutrophil extracellular traps, which are able to entrap ...

When activated by a pathogen encounter, histamine-releasing basophils are important in the defense against parasites and play a role in allergic reactions, such as asthma. [2] Upon activation, eosinophils secrete a range of highly toxic proteins and free radicals that are highly effective in killing parasites, but may also damage tissue during ...
