TREC and KREC as prognostic markers of HIV infection and COVID-19

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. The article reviews the effect of two RNA-containing viruses on the specific immune system: SARS-CoV-2 and HIV, as well as parameters of T- and B-cell neogenesis of TREC and KREC, which are markers of immunological disorders and can be used for prognosis for these infections. © 2022 New Terra Publishing House.
