Viruses are acellular, pathogenic agents that infect and destroy a host cell. Viruses are generally made up of either DNA or RNA and a protein capsid. Unlike microorganisms which can replicate on their own, viruses can only replicate inside a host cell. The first discovered virus was th...
Dawkins (1976) noted that a meme essentially parasitizes a brain, turning it into a vehicle for the meme’s propagation in just the way that a virus parasitizes the genetic mechanism of a host cell. An infectious agent or a pathogen causes disease or illness to its host, such as an ...
Viral mRNA is used to make viral proteins. Decreased expression of ACE2 in a host cell results in an attack on the airway epithelium by the virus. These lead to acute lung injury that triggers immune responses. The release of various pro-inflammatory and chemokines like IL-6, IFN- gamma,...
