HCV invades cells in the body by binding to specific receptors on the cell, enabling the virus to enter it.2 Once inside, HCV hijacks functions of the cell known as transcription, translation and replication, which enables HCV to make copies of its viral genome and proteins, allowing the virus to spread to other sites of the body.2 When HCV enters the host cell, it releases viral (+) RNA that is transcribed by viral RNA replicase into viral -LRB--) RNA, which can be used as a template for viral genome replication to produce more (+) RNA or for viral protein synthesis.

Harold Varmus: Well the simplistic way to think about that is and I'm not sure this is the way it will be worked out, is to be able to take just a few cells from those early lesions and examine them genetically or for other kinds of marks on the DNA that would predict whether or not this is some - this is a lesion which might or an early stage growth that might never be able to progress, but it is also possible that every early tumor of that kind has some probability of expanding and invading and growing to become a medical problem, so getting that right will obviously be crucial because it's very difficult to say when you've diagnosed something that is an early stage tumor that it won't progress.

Researchers focused on white blood cells called macrophages that work to destroy invading bacterial microbes.

BSI member Professor Michael Dustin, explains, «While an overwhelming T - cell response might on the face of it sound effective, it brings risks of immunopathology, where an over-active immune system destroys healthy human tissue, not just the invading disease - causing pathogen.

Taking the microbiome into account may be important for accurate phenotype - genotype analysis due to the increasing awareness of the impact the microbes have on different body sites, through the products they produce, their ability to protect against invading organisms, their direct interaction with the cell structures and the extracellular milieu, provoking inflammatory or immune responses, and many other effects.
