This is, in turn, surrounded by the viral envelope, that is composed of the lipid bilayer taken from the membrane of a human host cell when the newly formed virus particle buds from the cell.
The viral envelope contains proteins from the host cell and relatively few copies of the HIV Envelope protein, The Envelope protein, encoded by the HIV env gene, allows the virus to attach to target cells and fuse the viral envelope with the target cell's membrane releasing the viral contents into the cell and initiating the infectious cycle.
The resulting viral DNA is then imported into the cell nucleus and integrated into the cellular DNA by a virally encoded enzyme, integrase, and host co-factors.
The density is high as the glycans shield the underlying viral protein from neutralisation by antibodies.HIV infects vital cells in the human immune system such as helper T cells (specifically CD4 Lentiviruses have many morphologies and biological properties in common.Many species are infected by lentiviruses, which are characteristically responsible for long-duration illnesses with a long incubation period.We would personally like to thank all of the website template designers and developers for all of their hard work in creating these free website templates. AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.
