<html> Регулирование роста клеток и гибели клеток иммунных реакций занимает центральное место в роли фактора транскрипции семейства интерферона регуляторных факторов. Irf5 выделяется как решающее значение для регуляции иммунных реакций между 1-го типа, воспалительного ответа, способствующего и типа 2, ремонт иммунный ответ таргетирования ткани. Irf5 является ключевым фактором при раке 1 и аутоиммунитета 2, 3, 4, 5. Мышь плотно кожи (Tsk / +) является моделью для фиброза ткани и склеродермии вследствие мутации дублирования в гене фибриллин-1. Эта мутация приводит к сильной кожи и увеличение соединительной ткани. Эти мыши развивают воспаление миокарда, фиброза и , наконец , сердечной недостаточности 5, 6, 7,&gt; 8, 9. Склеродермия является аутоиммунным фиброзных расстройством , поражающим около 150 000 пациентов в Соединенных Штатах 6. Признаки этого заболевания являются фиброз внутренних органов , включая сердце 7, 8, 9, 10, 11. Характер исследования потребовал конструкцию ингибирующего пептида. Подход программного обеспечения был выбран более традиционный подход с использованием фагового дисплея. Подход программного обеспечения проще и займет меньше времени. Банк данных RCSB используется для идентификации соответствующих сайтов связывания 12. Для изучения взаимодействия недавно разработанного пептида с рекомбинантного белка и сосредоточиться на обязательных параметров, был использован метод, называемый бислоя интерферометрии. Бислоя интерферометрии является биосенсора на основе Techniqу.е, который определяет сродство к связыванию, ассоциацию и диссоциацию с использованием биосенсора и связывания образца. Биосенсор может быть флуоресцентно, люминесцентно, радиометрической и колориметрическим маркированы. Измерение основано на массовое добавление или истощение напоминающее ассоциацию и диссоциацию 13, 14. Цель данного исследования состояла в том, чтобы понять роль irf5 при воспалении миокарда и фиброз. Цель состояла в том, чтобы получить представление о роли irf5 в развитии фиброза тканей и склеродермии.

vasodilation of isolated vessels and the isolation of the extracellular matrix of tight-skin mice

The interferon regulatory factor 5 (IRF5) is crucial for cells to determine if they respond in a pro-inflammatory or anti-inflammatory fashion. IRF5's ability to switch cells from one pathway to another is highly attractive as a therapeutic target. We designed a decoy peptide IRF5D with a molecular modeling software for designing small molecules and peptides.
IRF5D inhibited IRF5, reduced alterations in extracellular matrix, and improved endothelial vasodilation in the tight-skin mouse (Tsk/+). The Kd of IRF5D for recombinant IRF5 is 3.72 &plusmn; 0.74 x 10-6 M as determined by binding experiments using biolayer interferometry experiments. Endothelial cells (EC) proliferation and apoptosis were unchanged using increasing concentrations of IRF5D (0 to 100 &#181;g/mL, 24 h). Tsk/+ mice were treated with IRF5D (1 mg/kg/d subcutaneously, 21 d). IRF5 and ICAM expressions were decreased after IRF5D treatment. Endothelial function was improved as assessed by vasodilation of facialis arteries from Tsk/+ mice treated with IRF5D compared to Tsk/+ mice without IRF5D treatment. As a transcription factor, IRF5 traffics from the cytosol to the nucleus. Translocation was assessed by immunohistochemistry on cardiac myocytes cultured on the different cardiac extracellular matrices. IRF5D treatment of the Tsk/+ mouse resulted in a reduced number of IRF5 positive nuclei in comparison to the animals without IRF5D treatment (50 &#181;g/mL, 24 h). These findings demonstrate the important role that IRF5 plays in inflammation and fibrosis in Tsk/+ mice.
