Non-specific immunity, or innate immunity, is the immune system with which you were born, made up of phagocytes and barriers. Phagocytosis , derived from the Greek words phagein , meaning to eat, kytos or cell, and “osis” meaning process, was first described by Élie Metchnikoff , who won the Nobel Prize 100 years ago.
Innate immune systems are found in all animals. [2] If pathogens successfully evade the innate response, vertebrates possess a second layer of protection, the adaptive immune system, which is activated by the innate response. [3] Here, the immune system adapts its response during an infection to improve its recognition of the pathogen.
The innate immune system or nonspecific immune system [1] is one of the two main immunity strategies in vertebrates (the other being the adaptive immune system). The innate immune system is an alternate defense strategy and is the dominant immune system response found in plants , fungi , prokaryotes , and invertebrates (see Beyond vertebrates ).
On Immunity: An Inoculation is a nonfiction book by Eula Biss published by Graywolf Press in 2014. It is primarily about vaccination of children. Bill Gates endorsed it on Twitter , saying " On Immunity is a great book that is not out to demonize anyone who holds opposing views."
The New York Times Book Review (NYTBR) is a weekly paper-magazine supplement to the Sunday edition of The New York Times in which current non-fiction and fiction books are reviewed. It is one of the most influential and widely read book review publications in the industry. [ 2 ]
Scheme of the complement system. The complement system, also known as complement cascade, is a part of the humoral, innate immune system and enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promote inflammation, and attack the pathogen's cell membrane.

Manhattan prosecutors urged a New York criminal court to keep President-elect Donald Trump's hush money case alive, even if sentencing is pushed out past Trump's next presidential term.
To make up for this lack of defense, plants use the pattern-triggered immunity (PTI) and effector-triggered immunity (ETI) pathways to combat trauma and pathogens. PTI is the first line of defense in plants and is triggered by PAMPs to initiate signaling throughout the plant that damage has occurred to a cell.
