Abstract

Especially when combined with unique biological adaptations, invertebrate animals provide important insights into innate immunity because the immune response is not complicated by adaptive immunity that vertebrates evolved. One such example is the digestive tract of the medicinal leech, Hirudo verbana, which is unusual in two aspects, it contains a simple microbial community and it stores large amounts of vertebrate blood for a several months. In this review we will discuss aspects of the innate immunity of the leech and from the ingested blood that we term procured immunity to differentiate it from the immunity encoded by the leech genome.

Zusammenfassung

Especially when combined with unique biological adaptations, invertebrate animals provide important insights into innate immunity because the immune response is not complicated by adaptive immunity that vertebrates evolved.

Warum dies für die Hirudotherapie relevant ist

This review discusses innate immunity in the digestive tract of the medicinal leech Hirudo verbana, which harbors a simple microbial community and stores vertebrate blood for months. The authors introduce the concept of 'procured immunity'—immune factors derived from ingested vertebrate blood that are distinct from immunity encoded by the leech genome. For ASH's domain, the article is relevant in that it examines fundamental biology of H. verbana, a species the abstract identifies as the 'medicinal leech,' focusing on its gut immune environment. However, this is a review presenting concepts of innate and procured immunity; it reports no new experimental data, clinical findings, or recommendations related to leech therapy practice. Its connection to therapeutic applications is indirect, limited to basic leech immunology.
