  • Title: The immune system in critical illness.
    Author: Marshall JC, Charbonney E, Gonzalez PD.
    Journal: Clin Chest Med; 2008 Dec; 29(4):605-16, vii. PubMed ID: 18954696.
    Abstract:
    The mammalian immune system comprises a complex network of physical and molecular elements that protect the individual from danger in the environment. An evolutionarily ancient innate immune system recognizes danger through pattern-recognition receptors that are encoded in the genome and mobilizes a rapid and potent but nonspecific response. This response is responsible for the clinical syndromes of sepsis and the multiple organ dysfunction syndrome. The adaptive immune system is highly selective in its targets and is endowed with memory but is slow in initial activation. Critical illness results in derangements of all components of the immune response, but the very complexity of the process has frustrated attempts to correct these derangements and to affect significantly the clinical course of sepsis.
