Вплив симвастатину та антагоніста рецепторів інтерлейкіну-1 на експресію аріл-гідрокарбонових рецепторів (AhR) в умовах експериментального гострого ілеїту

Вплив симвастатину та антагоніста рецепторів інтерлейкіну-1 на експресію аріл-гідрокарбонових рецепторів (AhR) в умовах експериментального гострого ілеїту

Abstract

Aryl hydrocarbon receptor (AhR) transcription factor activated by a large number of environmental agents, and may play a role in the pathogenesis of inflammatory bowel diseases in humans and mouse models. We have investigated the possibility of using simvastatin and interleukin 1 receptor antagonist for pharmacological correction of acute ileitis in rats, with a focus on the studying intensity of AhR expression by lymphocytes of the small intestine. The AhR-immunopositive lymphocytes were determined by means of indirect immunofluorescence technique using monoclonal rat antibodies. We have established that development of ileitis was associated with changes in the amount of AhR+ lymphocytes and their density on immunopositive cells. Drug administration during the development of experimental pathology was accompanied by changes in the expression of AhR and their density on lymphocytes.

Аріл-гідрокарбоновий рецептор (AhR) — фактор транскрипції, який активується великим числом факторів навколишнього середовища і може відігравати роль у патогенезі запальних за- хворювань кишечника у людини та в мишачих моделях. Ми вивчали можливість застосування сим- вастатину й антагоніста рецепторів інтерлейкіну-1 для фармакологічної корекції гострого ілеїту у щурів з акцентом на дослідженні інтенсивності експресії AhR лімфоцитами тонкої кишки. AhR- імунопозитивні лімфоцити визначали за допомогою методу непрямої імунофлюоресценції з ви- користанням моноклональних антитіл щура. Ми встановили, що розвиток ілеїту супроводжувався зміною кількості AhR+-лімфоцитів і щільності їх на імунопозитивних клітинах. Застосування препа- ратів під час розвитку експериментальної патології супроводжувалося змінами експресії AhR та їх щільності на лімфоцитах.
