Is the difference between HBV and HCV only a matter of alphabets?
Well, there is definitely more to it. Although both the HBV and HCV virions attack liver cells (hepatocytes), the life cycles of HBV and HCV and how they are harmfu to the human body varies widely.
Hepatitis B is a virus that is unable to attack the hepatocytes by itself. However, the human immune system is able to recognize that HBV virions are foreign particles and aim to destroy them. At the same time, the virions bind to the receptors on the liver cells and enter the cells thru receptor-mediated endocytosis. When the virions are in the human cell, the immune system is unable to differentiate the HBV virions from the hepatocytes leading to the destruction of the liver cells which damages the human liver as a whole. Another way the HBV virus attacks the liver is by mutating the DNA strands in the nucleus of the hepatocytes and most of us would know that mutations is a common cause of cancer.
HCV is also able to trigger the human immune system to attack its own cells but it has a completely different method of damaging the liver cells with its method of Replication
