Abstract
Cytomegalovirus (CMV) reactivation is a common complication after allogeneic haematopoietic stem cell transplantation (HSCT). It occurs in over a third of alloHSCT recipients, and is a major source of post-transplant mortality. miRNAs are small non-coding RNA molecules that are important regulators of gene expression. They are often dysregulated during disease, including transplant-related complications. Due to their presence in all body fluids, they can be used as potential biomarkers. In this study, we performed miRNA profiling to find differentially expressed host miRNAs in serum that could be linked to CMV reactivation after HSCT. CMV reactivation was confirmed by detection of CMV DNA in serum. We identified two miRNAs, miR-302d-3p (p < 0.001) and miR-6721-5p (p = 0.018), as differentially expressed between day + 30 and + 90 after HSCT in patients with CMV reactivation. Of these, miR-302d-3p was confirmed as overexpressed on day + 30 in a verification analysis performed on an independent cohort of patients (p = 0.027). Furthermore, we analysed two genetic variants in the gene coding for miR-302d-3p. We found one of them, rs13136737, to be significantly associated with CMV reactivation (p = 0.015). In conclusion, our study showed that miR-302d-3p is dysregulated and that its genetic variant rs13136737 may be important in development of CMV reactivation after HSCT.
期刊介绍:
The journal''s scope includes understanding the genetic and functional mechanisms that distinguish human individuals in their immune responses to allografts, pregnancy, infections or vaccines as well as the immune responses that lead to autoimmunity, allergy or drug hypersensitivity. It also includes examining the distribution of the genes controlling these responses in populations.
Research areas include:
Studies of the genetics, genomics, polymorphism, evolution, and population distribution of immune-related genes
Studies of the expression, structure and function of the products of immune-related genes
Immunogenetics of susceptibility to infectious and autoimmune disease, and allergy
The role of the immune-related genes in hematopoietic stem cell, solid organ, and vascularized composite allograft transplant
Histocompatibility studies including alloantibodies, epitope definition, and T cell alloreactivity
Studies of immunologic tolerance and pregnancy
T cell, B cell, NK and regulatory cell functions, particularly related to subjects within the journal''s scope
Pharmacogenomics and vaccine development in the context of immune-related genes
Human Immunology considers immune-related genes to include those encoding classical and non-classical HLA, KIR, MIC, minor histocompatibility antigens (mHAg), immunoglobulins, TCR, BCR, proteins involved in antigen processing and presentation, complement, Fc receptors, chemokines and cytokines. Other immune-related genes may be considered.
Human Immunology is also interested in bioinformatics of immune-related genes and organizational topics impacting laboratory processes, organ allocation, clinical strategies, and registries related to autoimmunity and transplantation.
