In this article we will discuss about the entry of adenovirus in host cell through attachment and endocytosis steps. The virus enters into the host cell through the steps as given below: (a) Attachment: Attachment to cells is rather slow and takes several hours to reach a maximum. Viral entry occurs into the two stages. An initial interaction of the [...]
In this article we will discuss about:- 1. Structure of HIV 2. Genome Organization of HIV-1 3. Steps of Entry 4. Replication 5. Assembly. Structure of HIV: HIV is different in structure from other retroviruses. HIV is of 100-120 nm diameters containing an protein envelope to which spicules of glycoprotein are attached. The envelope encloses an icosahedral capsid core that [...]
In this article we will discuss about the assembly, evolvement and release of herpesviruses. Assembly of Herpesviruses: There are more than 30 HSV-1 gene products that act as the structural components of the virion. These are expressed with late kinetics. Capsid assembly i.e. enveloping is a complex process. The general outline of the process was established by careful electron microscopic [...]
