Researchers in the United States have obtained the first precise structural data for the Andes virus, a pathogen that occasionally transmits from rodents to humans in South America and results in fatality for approximately 40% of those infected. According to a press release from the University of Texas system, this information will expedite the creation of vaccines.
Professor Jason McLellan commented that experts now possess a better comprehension of the internal organization of the Andes virus. This understanding facilitates the initiation of development for effective antibodies and vaccines specifically designed to prevent and treat this particular infection.
“A similar methodology could be employed to generate high-resolution images of the envelopes of numerous other types of hantaviruses,” TASS reported, quoting the scientist.
To conduct their structural analysis, the biologists constructed nanoparticles from individual components of the ANDV envelope and examined them using a cryo-electron microscope. This novel technique yielded a three-dimensional visualization possessing unprecedented resolution—as precise as one to two atoms in radius.
This in-depth examination revealed previously unseen characteristics in the construction and interplay of the envelope’s constituent elements, allowed for the correction of inaccuracies found in earlier analyses, and will accelerate the development of vaccines and antibodies targeting vulnerable viral components and similar disease agents.
Hantaviruses affect both rodents and humans. Severe instances may involve lung damage, cardiac failure, and hemorrhagic fever. The initial significant outbreak was documented near the Hantan River in Korea in 1951.
Recently, Russian scientists carried out a study where they analyzed the DNA of bacteriophage viruses found in water samples collected from depths of 2 kilometers. Furthermore, these specialists elaborated on the potential risks these viruses pose to human health.
