Biophysical characterization and membrane interaction of the most membranotropic region of the HIV-1 gp41 endodomain. MD simulations may be thought of as a computational microscope: one may ‘zoom in’ to atomic resolution to examine detailed interactions of a membrane protein with water, ions, and lipids, or ‘zoom out’ to a lower resolution using for example coarse-grained (CG) [5••, 6] simulations to address longer length and timescales, albeit with some loss of detail in modelling interatomic Cited by:

HIV-1 undergoes fusion with the cell membrane through interactions between its coat proteins and the target cell. Visualization of fusion with sufficient detail to determine the molecular mechanism remains elusive.

It plays important roles in HIV-1 replication such as mediating envelope (Env) intracellular trafficking and incorporation into assembling virions, mechanisms of which are poorly understood.
Here, we present the solution structure of gp41CT in a micellar environment and characterize its interaction with the by: HIV interactions with the plasma membrane resulted in a variety of membrane alterations. A com- monly observed consequence was formation of a modi- fied patch below the cell surface that appears to be a coated pit (Figs.

The IFITM genes are thought to inhibit HIV-1 entry by changing the composition and curvature of the plasma membrane, perhaps reducing its fluidity, thereby interfering with a phenomenon known as hemifusion [12, 13].Cited by: 6.
HIV particles interact with several receptors on cell surfaces. Two receptors, CD4, and a co-receptor act sequentially to trigger fusion of viral and cellular membranes and confer virus entry into cells.
These molecular interactions highlight several unique features of viral by: 1. The hivbook is a medical textbook that follows the concept of being independent, easy to read, and freely available on the Internet. The book has first been published in and has since been updated annually.
HIV / is the 23rd edition. History. It was previously reported that kB1 and a membrane-active mutant are able to target and disrupt the HIV virus-enveloped membrane as determined using a HLA-DR viral capture method. The membrane of HIV particles is very rich in PE, Chol, and SM and is assumed to be in liquid-ordered phase, being referred to as a raft-like membrane (50, 51).Cited by: By contrast, the second mechanism involves a direct interaction between the amyloidogenic protein and cholesterol.
Therefore, this effect requires the insertion of a part of the amyloid protein in the membrane; otherwise the protein would not be in physical contact with cholesterol. This interaction brings about another conformational change that exposes a previously buried portion of the transmembrane glycoprotein gp41 called the fusion peptide that enables the viral envelope to fuse with the host cell membrane (see Figure 1A, Figure 1B), and Figure 1C).

Volume 1: Viral Membrane Proteins: Structure, Function and Drug Design. Edited by Wolfgang B. Fischer. This volume, written by renowned Brand: Springer US. Plasma membrane is a multifunctional structure that acts as the initial barrier against infection by intracellular pathogens.
The productive HIV-1 infection depends upon the initial interaction of virus and host plasma by: This volume emphasizes the critical role that membrane structure and fluidity play in the modulation of cellular function in both healthy and pathological states.
It evaluates the role that the membrane structure plays in the ability of HIV and related viruses to interact with host cells. Biology of HIV HIV (human immunodeﬁciency virus) is composed of two strands of RNA, 15 types of viral proteins, and a few proteins from the last host cell it infected, all surrounded by a lipid bilayer membrane.
Together, these molecules allow the virus to infect cells of the immune system and force them to build new copies of the virus. Each File Size: 1MB. Schematic representation of HIV-1 mucosal transmission.
HIV-1 mucosal transmission is a multifaceted process of virus-host interactions. Initial HIV-1 infection mainly occurs at the mucosal surfaces, involving epithelial cells, dendritic cells, CD4 + T cells, and macrophages.

The replication of HIV-1 is strongly enhanced by a small membrane protein called virus protein U (Vpu). Vpu achieves its task by (a) interacting with CD4, the HIV-1 receptor, and (b) by amplifying particle release at the site of the plasma : V.
