Viruses have also developed a variety of immunomodulation mechanisms to subvert the host immune response. This tend to feature virus-encoded decoy receptors that target cytokines and chemokines produced as part of the host immune response, or homologues of host cytokines.
The virus wraps its delicate nucleic acid with a protein shell known as the capsid, from the Latin capsa, meaning "box," in order to shield it from this hostile environment. Similar to how numerous bricks come together to form a wall, the capsid is made up of one or more distinct protein types that repeatedly repeat to form the whole capsid.
Gamma phage, an example of virus particles (visualised by electron microscopy) Virology is the scientific study of biological viruses.It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they ...
Zoo visitors are tossing bananas and pouring water on the adorable, two-month-old pygmy hippo in an attempt to get her attention. The post Moo Deng, Viral 2-Month-Old Baby Hippo, Disrupted By ...
A virus with this "viral envelope" uses it—along with specific receptors—to enter a new host cell. Viruses vary in shape from the simple helical and icosahedral to more complex structures. Viruses range in size from 20 to 300 nanometres; it would take 33,000 to 500,000 of them, side by side, to stretch to 1 centimetre (0.4 in).
france hippo But a video that's getting attention on Digg will bring you back to reality -- and it'll blow your mind. The footage shows a man in Japan giving the hippos a not-so-little treat.
Moo Deng, whose name roughly translates to “bouncy pig,” is a 2-month-old female pygmy hippopotamus. Pygmy hippos are an endangered species, with fewer than 3,000 remaining in the wild.
Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms. Viruses are classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
