What is innate immune system?

Innate Immune System

The innate immune system, also known as non-specific immune system and first line of defense, comprises the cells and mechanisms that defend the host from infection by other organisms in a non-specific manner. This means that the cells of the innate system recognize and respond to pathogens in a generic way, but unlike the adaptive immune system, it does not confer long-lasting or protective immunity to the host. Innate immune systems provide immediate defense against infection, and are found in all classes of plant and animal life.

Famous quotes containing the words immune system, system, innate and/or immune:

    The moral immune system of this country has been weakened and attacked, and the AIDS virus is the perfect metaphor for it. The malignant neglect of the last twelve years has led to breakdown of our country’s immune system, environmentally, culturally, politically, spiritually and physically.
    Barbra Streisand (b. 1942)

    Social and scientific progress are assured, sir, once our great system of postpossession payments is in operation, not the installment plan, no sir, but a system of small postpossession payments that clinch the investment. No possible rational human wish unfulfilled. A man with a salary of fifty dollars a week can start payments on a Rolls-Royce, the Waldorf-Astoria, or a troupe of trained seals if he so desires.
    John Dos Passos (1896–1970)

    It must not be thought that the cowardly feeling of caution and uneasy self-preservation is innate in the English character. It is the consequence of a corpulence derived from wealth and of the training of all thoughts and passions for acquisitiveness.
    Alexander Herzen (1812–1870)
