Detailed explanation-1: -HIV/AIDS Glossary The outer coat of HIV, made up of two layers of lipids (fatty molecules). HIV uses protein “spikes” embedded in its envelope to enter host cells.
Detailed explanation-2: -The human immunodeficiency virus type 1 (HIV-1) is an enveloped virus that follows a membrane fusion strategy to access and activate the replication cycle within the cytoplasm of host cells, typically CD4+ T cells and cells of the monocyte/macrophage lineage1.
Detailed explanation-3: -The Env glycoprotein is found on the surface of HIV, forming little knobs composed of three identical subunits. It is covered with carbohydrate, with about 81 glycosylated sites on each trimer. It is encoded in the HIV genome as one long protein, which is called gp160 (gp is short for “glycoprotein").
