Abstract
Human health has a significant importance and it is directly affected by a number of factors like different diseases including microbial and viral infections. Up till now we have paid attention to the disease causing viruses and pathogens and less has been investigated about the usefulness of normal viral flora. One such orphan virus is Torque Teno Virus (TTV). The virus is present in healthy as well as diseased population, indicating its high prevalence. The virus is ubiquitous to human body as it is present in almost all tissues and organs and this is the property that can be utilized for targeted drug delivery. Another potentially useful property of this virus is TTV derived Apoptosis Inducing protein that can be a hope for the affectees.
Highlights
Viruses are small, tiny infectious agents that use the host cell machinery for replication
On the other hand there are certain other agents that are associated with hepatocytes but their clear association with hepatitis is not established yet and they are Hepatitis G Virus (HGV) and Torque Teno Virus (TTV) [3,4]
It is yet to be known that which type of cells provide replication machinery for TTV, some studies have shown the presence of mRNA forms and double stranded DNA of TTV in bone marrow, in various human organs and in tissues which indicates that they can be an active replication sites of TTV
Summary
Tiny infectious agents that use the host cell machinery for replication. The first ever virus to be identified and reported was Tobacco Mosaic Virus. The word “virus” is derived from Latin word meaning “poison”. It is believed by certain schools of thoughts that viruses have co-evolved with humans. Viruses are composed of two essential parts i.e. Viral Genome composed of DNA or RNA which could be either single stranded or double stranded and a protein coat which surrounds the genome and its symmetry can be either helical, icosahedral or complex, In some viruses the protein coat is embedded by a lipid bilayer derived from host cell making third part of their structure [1,2]
