Schistosoma mansoni: evidence that eosinophils and/or macrophages contribute to skin-phase challenge attrition in vaccinated CBA/Ca mice

Parasitology

Abstract

Naive CBA mice and mice vaccinated 4 weeks previously with gamma-irradiated cercariae were challenged percutaneously with normal cercariae and the skin site of challenge removed at various times to provide samples for histological examination. Neutrophil abscesses surrounding schistosomula as well as cast cercarial tails were identified at the skin surface in both naive/challenged and vaccinated/challenged mice. The dermis in both groups of animals became infiltrated with mononuclear cells and granulocytes. Neutrophils were the predominant granulocyte in naive/challenged skin but eosinophils replaced neutrophils by 48 h post-challenge in skin from vaccinated mice. Schistosomula with adherent mononuclear cells and granulocytes were identified preferentially in the dermis of vaccinated mice; such larvae frequently exhibited subtegumental vacuolation. A further major characteristic of vaccinated/challenged skin was the formation, from 18 h, of extensive subdermal inflammatory foci, consisting of up to 50% mononuclear cells and 50% eosinophils. These foci invariably surrounded one or more larval parasites which were seen by both optical and scanning electron microscopy to have a morphology typical of lung stage rather than skin sta...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.
