The Dynamic Changes in Soluble CD30 and Regulatory T Cells Before and After Solid Organ Transplantations: A Pilot Study

Monoclonal Antibodies in Immunodiagnosis and Immunotherapy
Velislava TerzievaLubomir Spassov

Abstract

Among multiple parameters, applied in the immunologic monitoring of transplantation, the levels of serum soluble CD30 (sCD30) and peripheral regulatory T cells (Tregs) are very promising. These are relatively new biomarkers, considered to reflect immune activation and tolerance in solid organ transplantation. Results are shown here from a preliminary study on the relevance of sCD30 and Tregs in the monitoring of the early post-transplantation period. Sixteen patients with chronic liver or kidney disease were examined. Nine of them were further selected for transplantation. Follow-up of sCD30 and Tregs was carried out during the first month after transplantation. Until day 30 (D30) after transplantation, a progressive decrease in sCD30 levels was observed in all patients. Conversely, the dynamic of Tregs was dependent on the transplanted organ: in liver recipients, an increase of Tregs was detected at day 7 (D7) followed by a gradual decrease until D30, whereas in kidney recipients, a sustained downward trend starting on D7 was observed. In liver recipients, the increase in Tregs preceded albumin normalization, whereas in kidney recipients, sCD30 was found to have predictive significance for the creatinine levels. Our results de...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
