What is eosinophil protein X EPX?

What is eosinophil protein X EPX?

Eosinophil protein X (EPX), also known as eosinophil-derived neurotoxin (EDN), is a basic cellular protein with potent cytotoxic and neurotoxic properties and is a marker of eosinophil activation and degranulation.

How do eosinophils regulate inflammation?

Eosinophils are potent effector cells implicated in allergic responses and helminth infections. Responding to stimuli, they release their granule-derived cytotoxic proteins and are involved in inflammatory processes.

How can eosinophil adjust or modulate an inflammatory process?

In Th2-type immune response, eosinophils are recruited into sites of inflammation where they produce an array of cytokines and lipid mediators and release toxic granule proteins. These molecules may regulate immune responses, cause tissue damage, and facilitate tissue repair.

What is EPX stool test?

EPX/EDN ELISA tests in stool samples Elevated levels of fecal EDN are linked to multiple inflammatory conditions, like food allergy/sensitivity, pathogenic infections (C. difficile and H. Pylori), IBS, Eosinophilic Gastrointestinal Disorders.

What happens if the eosinophils are high?

Eosinophilia (e-o-sin-o-FILL-e-uh) is a higher than normal level of eosinophils. Eosinophils are a type of disease-fighting white blood cell. This condition most often indicates a parasitic infection, an allergic reaction or cancer.

Why do eosinophils cause inflammation?

Recruitment of activated eosinophils from the bloodstream into tissues can occur under a variety of conditions and lead to the release of preformed and newly synthesized products, including cytokines, chemokines, lipid mediators and cytotoxic granule proteins, that can initiate, quickly escalate and sustain local …

What is the role of eosinophils in inflammation?

Eosinophils can consume foreign substances. For example, they fight substances related to parasitic infection that have been flagged for destruction by your immune system. Regulating inflammation. Eosinophils help promote inflammation, which plays a beneficial role in isolating and controlling a disease site.

What is the function of eosinophil?

Eosinophilic functions include: movement to inflamed areas, trapping substances, killing cells, anti-parasitic and bactericidal activity, participating in immediate allergic reactions, and modulating inflammatory responses.
