Receptor-mediated Endocytosis

Receptor-mediated Endocytosis

Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

Retroviruses

Retroviruses

Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

Retrovirus Life Cycles

Retrovirus Life Cycles

Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the retrovirus to...

Viruses with RNA Genomes

Viruses with RNA Genomes

RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Influenza

Influenza

Influenza is an acute, highly communicable viral disease that affects the respiratory tract and is responsible for seasonal epidemics worldwide. Influenza A is the most prevalent type associated with widespread outbreaks and is subtyped based on two surface glycoproteins: hemagglutinin (H) and neuraminidase (N), as in H1N1. These glycoproteins are essential for viral infectivity, transmission, and immune recognition. Transmission occurs primarily through respiratory droplets and contaminated...

Summary

Nipah virus (NiV) and Hendra virus (HeV) are deadly Paramyxoviruses. This review explores how their use of ephrin-B2/B3 receptors influences viral spread and disease in hosts.

Area of Science:

Virology
Molecular Biology
Pathogen Research

Background:

Nipah virus (NiV) and Hendra virus (HeV) are highly pathogenic Paramyxoviruses.
These viruses cause severe respiratory and neurological diseases in humans and animals.
Henipaviruses (HNV) are BSL4 pathogens with no licensed vaccines or therapeutics.

Purpose of the Study:

To review the biology of HNV receptors, ephrin-B2 and ephrin-B3.
To examine the relationship between HNV receptor usage and viral tropism.
To understand how receptor interactions contribute to HNV pathobiology.

Main Methods:

Main Results:

HNV utilize conserved ephrin-B2 and ephrin-B3 proteins as viral entry receptors.
Receptor usage explains the broad species tropism of HNV.
Understanding receptor interactions is key to HNV pathobiology.

Conclusions:

Ephrin-B2 and ephrin-B3 are critical determinants of HNV infection.
Targeting these receptors may offer therapeutic strategies.
Further research into HNV-receptor interactions is crucial for disease control.
