Quantitation of cytomegalovirus (hCMV) DNA and beta-actin DNA by duplex real-time fluorescence PCR in solid organ (liver) transplant recipients.

Even now rare human cytomegalovirus (hCMV) reactivation is still a life-threatening complication after solid organ transplantation. Although PCR techniques are regarded as the most sensitive detection methods for hCMV, their accuracy and reproducibility are limited. This is a major disadvantage with quantitative PCR assays, which are thought to provide valuable information about hCMV latency or active viral replication in transplant patients.

Quantitation of the spliced late gene of human cytomegalovirus and its kinetics during experimental infection.

Human cytomegalovirus (hCMV) infection is still a cause of morbidity and mortality after solid organ and bone marrow transplantation and in other immunocompromised states. 'Preemptive therapy' strategies necessitate sensitive and specific methods for rapid diagnosis of symptomatic hCMV infection and monitoring of antiviral treatment. For analysis of the lytic stage of viral replication, the molecular determination of late transcripts is a useful approach for diagnosis of hCMV disease.

Two subsets of naive T helper cells with distinct T cell receptor excision circle content in human adult peripheral blood.

During ageing thymic function declines and is unable to meet the demand for peripheral T helper (Th) cell replenishment. Therefore, population maintenance of naive Th cells must be at least partly peripherally based. Such peripheral postthymic expansion of recent thymic emigrants (RTEs) during ageing consequently should lead to loss or dilution of T cell receptor excision circles (TRECs) from a subset of naive T cells.
