Abstract

MicroRNAs (miRNAs), a subclass of small regulatory RNAs that present from ancient unicellular protozoans to parasitic helminths and parasitic arthropods. MiRNAs' mode of action has attracted wide attention as a result of their unique functional importance. MiRNAs play a role in diverse physiological and pathological processes ranging from organ development, immune function to apoptosis and cancer at the post-transcription gene expression. Thus, miRNAs are known to be targets for clinical treatment and therapy. The discovery of the high stability of circulating miRNA in various types of host body fluids, such as whole blood, serum, plasma, saliva, and urine has increased great interest among researchers in the potential of circulating miRNA as a prognosis/diagnosis of infectious. Some circulating miRNAs biomarkers advanced to clinical applications related to human diseases. However, this idea starts to come only in the fields of infectious disease. The goal of this review is to enhance the current understanding of these molecules and their applicability in the field of medicine. A detailed review of the available literature consulting tools performed in online repositories such as NCBI, PubMed, Medline, ScienceDirect, and UpToDate. This review summarizes an overview of preclinical studies using circulating miRNAs biomarkers against infectious diseases affecting humans. The use of miRNA as a safe and potential tool is encouraging news, considering that until now, guidelines for the use of miRNA in clinical practice are still lacking. © 2021, Indian Society for Parasitology.
