ID Viruses pharm
how do viruses get into a host cell?
Viral replication is dependent on the specificity of virus binding to a particular host tissue
Specific structures on the virus recognize receptors on the host cell surface
Once attached, the virus must penetrate the host cell
what happens when viruses get inside?
This is followed by using host machinery to transcribe viral RNS into proteins needed to make more virus
Antiviral drugs target a viral enzyme or protein needed by the virus but not the host
immunocompromised immune systems and viruses:
A competent immune system will be able to eliminate or control a viral infection
The immunocompromised, such as AIDS, transplant or cancer patients are more likely to have frequent viral infections
how do antivirals work?
Must possess the ability to enter cells infected with a virus
The ability to interfere with viral binding, RNA, DNA or protein synthesis
