Аннотация

Изучен ряд препаратов, рассматриваемых в качестве кандидатов для лечения заболевания, вызванного вирусом Эбола, из них наибольшим терапевтическим потенциалом обладают смеси моноклональных антител (МКАт). Преимущества использования МКАт заключаются в низкой токсичности, высокой специфичности и универсальности. Диапазон биологического действия МКАт зависит от Fc-фрагмента антител. Свойства МКАт включают опсонизацию патогена, активацию комплемента, антителозависимую клеточную цитотоксичность и вируснейтрализующие характеристики. Наиболее известной смесью МКАт, используемой для лечения, является ZMapр, производимая фирмой «Leaf Biopharmaceutical» с 2004 г. В статье рассмотрены разработанные смеси МКАт, их структура и свойства, защитная эффективность и создание новых видов МКАт, специфичных для всех представителей рода Еbolavirus.

Abstract

Some drugs candidates for treatment of Ebola virus disease (EVD), have been studied, monoclonal antibody (mAb) cocktails have shown great potential as EVD therapeutics. The advantages of mAb therapy include low toxicity, high specificity and versatility, with the range of biological effects being dependent upon the Fc region. Functions of mAbs include pathogen opsonisation, complement activation, antibody-dependent cell cytotoxicity and virus neutralization characteristics. The most known mAb cocktail, used as therapeutic, is ZMapр, manufactured by «Leaf Biopharmaceutical» from 2004. The elaborated mAb cocktails, structures and properties s of mAbs, the protective characteristics of mAbs and development of new pan-ebolavirus mAbs are reviewed in this article.
