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 ...
Immunology is a science that examines the structure and function of the immune system. It originates from medicine and early studies on the causes of immunity to disease. The earliest known reference to immunity was during the plague of Athens in 430 BC.
Intrinsic immunity comprises cellular proteins which are always active and have evolved to block infection by specific viruses or viral taxa. [2] The recognition of intrinsic immunity as a potent anti-viral defense mechanism is a recent discovery and is not yet discussed in most immunology courses or texts.
Some viruses evade this by producing molecules that interfere with IFN production. For example, the Influenza A virus produces NS1 protein, which can bind to host and viral RNA, interact with immune signaling proteins or block their activation by ubiquitination , thus inhibiting type I IFN production.

Often we just think of a few viruses—influenza, HIV, and now coronaviruses—but viruses are the most plentiful microbes on the planet. Of those, about 320,000 types of viruses infect mammals ...
We have not yet developed vaccines against all viruses, but we also have an array of targeted drugs that work to treat specific viruses if we get infected with them. Bacteria are larger and more ...
Immunology is a branch of biology and medicine [1] that covers the study of immune systems [2] in all organisms.. Immunology charts, measures, and contextualizes the physiological functioning of the immune system in states of both health and diseases; malfunctions of the immune system in immunological disorders (such as autoimmune diseases, hypersensitivities, [3] immune deficiency, [4] and ...
Correlates of immunity or correlates of protection to a virus or other infectious pathogen are measurable signs that a person (or other potential host) is immune, in the sense of being protected against becoming infected and/or developing disease. For many viruses, antibodies and especially neutralizing antibodies serve as
