Summary
Cellular microdomains like lipid rafts are crucial for HIV-1 assembly and spread. Understanding these membrane structures offers insights into viral replication and transmission.
Area of Science:
- Cell Biology
- Virology
- Biophysics
Background:
- Cellular membranes contain specialized microdomains, including lipid rafts and tetraspanin-enriched microdomains (TEMs).
- Many enveloped viruses, including HIV-1, exploit these microdomains for their replication cycle.
- The role of plasma membrane (PM) microdomains in HIV-1 assembly is increasingly recognized.
Purpose of the Study:
- To review the current understanding of the relationship between PM microdomain organization and HIV-1 particle assembly.
- To discuss the potential impact of microdomains on post-assembly events, including virus release and cell-to-cell transmission.
Main Methods:
- This review synthesizes existing research on membrane microdomains and HIV-1.
- It focuses on the association of HIV-1 with lipid rafts and TEMs.
- The discussion includes the roles of specific proteins like BST-2/tetherin.
Main Results:
- HIV-1 assembly is closely associated with lipid rafts and TEMs in the plasma membrane.
- Microdomain organization influences HIV-1 particle assembly and release.
- Microdomains play roles in inhibiting virus release (BST-2/tetherin) and facilitating cell-to-cell transmission at virological synapses.
Conclusions:
- Plasma membrane microdomains are integral to HIV-1 assembly, release, and transmission.
- Targeting microdomain interactions could be a strategy to control HIV-1 spread.
- Further research into microdomain dynamics is essential for understanding HIV-1 pathogenesis.

00:59Mechanisms of Membrane Domain Formation
Different physical properties of lipids and proteins allow them to localize and form distinct islands or domains in the membrane. Some membrane domains are formed due to protein-protein interactions, whereas others are formed due to the presence of specific lipids such as sphingolipids and sterols—for example, large proteins, such as bacteriorhodopsin, aggregate and create distinct domains.

01:19Inhibitors of Virion Maturation and Assembly
As part of their replication cycle, certain viruses synthesize long precursor proteins called polyproteins within infected host cells. In human immunodeficiency virus (HIV), two major polyproteins are produced: Gag and Gag-Pol. The Gag polyprotein supplies the structural components of the virus, while Gag-Pol includes essential viral enzymes such as reverse transcriptase, integrase, and protease. After synthesis, these polyproteins move to the host cell membrane, where they assemble into an...
01:18Membrane Domains
The membrane domains concentrate specific lipids and proteins at one place within the membrane, which helps in cell signaling, adhesion, and other critical cellular processes. These domains can differ in size, composition, function, and lifespan.
Protein Domains
The membrane comprises a group of distinct proteins responsible for carrying out a cell's specific function. For example, the plasma membrane of the human sperm, or a single germ cell, contains a unique set of proteins in the anterior...

02:41Protein Complex Assembly
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

01:38Intralumenal Vesicles and Multivesicular Bodies
Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...
01:24What are Membranes?
A cell's plasma membrane demarcates the cell's borders and determines the nature of its interaction with the environment. Cells exclude certain substances, take in others, and excrete some others in controlled quantities. The plasma membrane must be flexible to allow certain cells, such as red and white blood cells, to change their shape while passing through narrow capillaries. These are the more obvious plasma membrane functions. In addition, the plasma membrane's surface carries markers that...
