RNA: Not Just a Helper

Many new categories of RNA have been discovered recently that show increasing evidence of the importance of RNA in gene expression beyond the transcription/translation process. These categories, previously thought to only exist in germ cells, have been found to play a vital role in the plasticity of the brain. One category, piRNA is found abundantly in the hippocampus and thought to express their own unique proteins. These RNA are also thought to be responsible for the bodies response to pathogens and is thought that their further investigation can help understand how to inhibit Hepatitis.
