Zusammenfassung
Die Mukosa, welche das humane Kolon und den Dünndarm begrenzt,
ist ein Gebiet von chronischer, regulierter, „physiologischer”
Entzündung. Dies stellt einen deutlichen Gegensatz zu anderen mukosalen
Gebieten des Körpers dar, denn fänden sich die gleiche Anzahl von T-
und B-Lymphozyten, Eosinophilen, Mastzellen, Makrophagen und dendritischen
Zellen, wie sie im humanen Intestinaltrakt vorhanden sind, in anderen
Bereichen, so würde man diese Orte als Orte von chronisch pathologischer
Entzündung bezeichnen. Diese Übersicht beschreibt die Rolle des
intestinalen Epithels bei der Entstehung dieser
„physiologischen”, intestinalen, mukosalen Entzündung und
konzentriert sich dabei auf dessen Rolle im Rahmen der Initiierung und
Vermittlung von angeborenen und erworbenen mukosalen Immunantworten.
Abstract
The mucosa that lines the human colon and small intestine is a site
of chronic regulated “physiologic” inflammation. This contrasts
markedly with other mucosal sites in that if the numbers of T and B cells,
eosinophils, mast cells, macrophages, and dendritic cells that are present in
the human intestinal tract were to be present in other sites, those sites would
be considered to be sites of chronic pathological inflammation. This review
examines the role of the intestinal epithelium in the development of
“physiologic” intestinal mucosal inflammation and focuses on its
role in signalling and mediating host innate and adaptive mucosal immune
responses.
