2023
Drug discovery is a multifaceted process involving extensive screening, testing, and optimization of lead compounds to identify potential new drugs for therapeutic use. It combines several approaches, including screening large numbers of natural products, chemical modification of known active molecules, identification of new drug targets, and rational design based on biological mechanisms and drug-receptor structure. These approaches are carried out in both academic research laboratories and...

What are Viruses?

2019
Overview A virus is a microscopic infectious particle that consists of an RNA or DNA genome enclosed in a protein shell. It is not able to reproduce on its own: it can only make more viruses by entering a cell and using its cellular machinery. When a virus infects a host cell, it removes its protein coat and directs the host’s machinery to transcribe and translate its genetic material. The hijacked cell assembles the replicated components into thousands of viral progeny, which can rupture and...

Three assays, including the cytopathic effect (CPE)-based assay, dose-response assay and Time-of-Addition (ToA) assay have been developed, optimized, validated and utilized to identify novel antivirals against Bluetongue virus (BTV), as well as to determine the possible Mechanism-of-Action (MoA) for newly identified antivirals.
FAQs
Metagenomic sequencing can detect viral genetic material without prior knowledge of the virus and without requiring successful laboratory culture. This makes it useful when an unfamiliar agent is present in a clinical, environmental, or animal sample but cannot be readily grown. The approach broadens discovery beyond viruses that fit existing expectations or culture conditions.
Researchers compare the candidate’s genetic material with known viral genomes to identify genetic relationships. This comparison can indicate whether the sequence resembles recognized viruses or represents a more distinct lineage, providing a basis for characterization. It does not by itself establish host range, replication, or disease relevance, so those questions require additional testing.
Finding viral genetic material shows that virus-associated sequences are present in a sample, but it does not establish how broadly the virus can infect hosts, whether it replicates, or whether it contributes to disease. Additional testing addresses these separate questions. Distinguishing them helps prevent genetic detection from being interpreted as proof of pathogenic importance.
Researchers begin with clinical, environmental, or animal samples and analyze them for viral genetic material. Metagenomic sequencing can support detection without requiring prior knowledge or successful culture. Bioinformatic comparison then examines relationships to known viral genomes, followed by testing of host range, replication, and disease relevance. The resulting evidence supports characterization and interpretation.
Characterizing a newly identified virus helps clarify how it interacts with host immunity, linking viral features to the immune responses observed during infection. This places discovery within immunology and infection research rather than treating sequencing as an isolated identification step. It can also guide follow-up work on diagnostic assays and vaccines.
Clinical, environmental, and animal samples can all provide opportunities to detect previously unrecognized viruses. Including these sample types extends discovery beyond a single setting and supports infection surveillance across relevant contexts. The sample source also informs subsequent investigations, including assessments of host range, replication, and possible disease relevance.
