[Frequency of the occurrence of spliced variants of the messenger RNA DR3/LARD in herpesviral infection].

Analysis of frequency of the occurrence of membrane and soluble forms of the mRNA DR3/LARD in blood in herpesviral infection of various etiology was studied. Four forms of the mRNA DR3/LARD were detected with various frequencies in blood cells of healthy volunteers. Patients with herpesviral infection of various etiology were studied using RT-PCR. Two forms encoded membrane molecules (mRNA LARD 1a, mRNA DR3beta) and two other forms accorded soluble forms of receptor (mRNA LARD 3, mRNA soluble DR3beta). It was revealed that the frequency of the occurrence of mRNA soluble DR3beta form decreased in patients with the varicella zoster virus (VZV) infection in comparison with healthy volunteers. However, the patients with the Epstein-Barr virus (EBV) and cytomegalovirus (CMV) infection did not display significant change in occurrence of mRNA soluble DR3beta form. As a whole, changes in frequency of occurrence of spliced variants of mRNA DR3/LARD are directed toward modulation of apoptosis and restraint antiviral immune response.
