Viral Tropism - an overview | ScienceDirect Topics
Viral tropism is the ability of different viruses to infect different cellular types ultimately to produce a successful infection. Being parasitic entities, cellular tropism is one of the major characteristics of viruses to maintain a successful infectious cycle in target cells.
Receptors and tropisms of envelope viruses - PMC
The ability of envelope proteins of a particular virus to bind and fuse with target cells defines the host range of the virus, known as “viral tropism”. The mechanism(s) of fusion by the viral envelope is largely categorized as either pH-dependent or –independent.
Viral Tropism - PMC
There are two major types of viral tropism, that is, the receptor-dependent and -independent tropisms. Restriction of viral replication occurs on the cell surface (receptor-dependent viral entry step) and/or intracellularly (receptor-independent post-entry replication steps).
Viral Pathogenesis - Medical Microbiology - NCBI Bookshelf
Viral affinity for specific body tissues (tropism) is determined by (1) cell receptors for virus, (2) cell transcription factors that recognize viral promoters and enhancer sequences, (3) ability of the cell to support virus replication, (4) physical barriers, (5) local temperature, pH, and oxygen tension enzymes and non-specific factors in ...
Basic Concepts: A Step-by-Step Guide to Viral Infection - PMC
The ability of a virus to enter various types of cells is one of the major determinants of viral tropism. Virus attachment factors. Initial viral attachment often occurs via relatively nonspecific, low affinity interactions with virus attachment factors.
Viral Tropism: Mechanisms and Effects on Host Cells
2024年10月19日 · Viruses exhibit a remarkable ability to selectively infect specific cells or tissues, a phenomenon known as viral tropism. This selectivity is essential for understanding how viruses cause disease and spread within hosts.
Viral Tropism - an overview | ScienceDirect Topics
The capacity of a virus to infect cells selectively in particular organs is referred to as tropism (either cell or organ tropism), which is dependent on both viral and host factors. At the cellular level, there must be an interaction between viral attachment proteins …
9.5C: Tissue Tropism in Animal Viruses - Biology LibreTexts
2024年11月23日 · In virology, Tissue tropism is the cells and tissues of a host that support growth of a particular virus or bacteria. Some viruses have a broad tissue tropism and can infect many types of cells and tissues. Other viruses may infect primarily a single tissue.
Cytokine determinants of viral tropism - Nature
2009年8月21日 · Viral tropism is the ability of a given virus to productively infect a particular cell (cellular tropism), tissue (tissue tropism) or host species (host tropism).
Viral Tropism - an overview | ScienceDirect Topics
The capability of a virus to infect a distinct group of cells in the host is referred to as tropism. For many viruses, tropism is determined by the availability of virus receptors on the surface of a host cell.
