LP13936-7 Cat dander
Cat-allergic patients with IgE antibodies to Fel d 1 have been shown also to react to the corresponding protein of ocelot, puma, serval, siberian tiger, lion, jaguar, and snow leopard. A subgroup of cat-allergic patients also react to dogs and sometimes to other animals. Serum albumin is the main common component. Extensive cross-reactivity even occurs between albumins of distantly related species and subjects with IgE antibodies to cat albumin may also react to horse, cattle, pig, rodents, and fur animals like mink and fox. However, great variability exists between patients and selective sensitivity to limited numbers of species occurs, indicating shared and specific epitopes.
Common and species-restricted epitopes have also been observed on the major cat and dog allergens Fel d 1 and Can f 1.
Allergy to cat dander and pork meat, also referred to as the pork/cat syndrome, was shown to be mediated by IgE antibodies recognizing cat and pig serum albumin. In addition, other kinds of meat may be a risk for patients with this type of sensitivity, as indicated by a case with cat-specific IgE antibodies and exercise-induced anaphylaxis after eating pork or beef.

LP32397-9 Ab.IgG4
IgG4 is the least common subtype of IgG, and it has a variety of functions. In the context of allergic disease it is thought to have an immune-inhibitory role in preventing anaphylaxis and is commonly known as a "blocking" antibody. IgG4 binding to an allergen can compete with IgE-mediated binding, thereby inhibiting the activation of mast cells and basophils and IgE-mediated presentation to T-cells. Measuring IgG4 and its ratio to IgE has a role in monitoring allergen specific immunotherapy PMID: 26023323. IgG4 is also thought to have a role in autoimmunity and be involved in a less defined entity known as IgG4-Related Disease, a chronic immune-mediated fibroinflammatory disorder that often manifests with tumor-like masses .https://www.merckmanuals.com/professional/musculoskeletal-and-connective-tissue-disorders/igg4-related-disease/igg4-related-disease
