В обзоре рассмотрено влияние на специфическое звено иммунитета двух РНК-содержащих вирусов: SARS-CoV-2 и ВИЧ, а также показатели Т- и В- клеточного неогенеза TREC и KREC, которые являются маркерами иммунологических нарушений и могут быть использованы для их прогноза.</p></abstract><trans-abstract xml:lang="en"><p>In some infectious diseases, the number of T- and B-lymphocytes is significantly reduced which is associated with a high risk of the disease progression.
