V - Diseases of the Immune System Flashcards
This term refers to protection against infections.
Immunity
Robbins Basic Pathology, 8th Ed p.108
It is the collection of cells and molecules that are responsible for defending against pathogenic microbes.
Immune system
Robbins Basic Pathology, 8th Ed p.108
Type of immunity mediated by neutrophils, macrophages and natural killer cells and includes epithelial barriers of the skin, GIT and respiratory tract.
Innate immunity (natural/native)
Robbins Basic Pathology, 8th Ed p.108
Type of immunity mediated by lymphocytes and their products, and is normally silent and responds to the presence of microbes by becoming active, expanding and generating potent mechanisms for neutralizing and eliminating microbes.
Adaptive immunity (acquired/specific)
Robbins Basic Pathology, 8th Ed p.108
Type of adaptive immunity mediated by soluble antibody proteins that are produced by B lymphocytes.
Humoral immunity
Robbins Basic Pathology, 8th Ed p.109
Type of adaptive immunity mediated by T lymphocytes.
Cell-mediated or cellular immunity
Robbins Basic Pathology, 8th Ed p.109
Mediated by antibodies and is effective against extracellular microbes.
Humoral immunity
Robbins Basic Pathology, 8th Ed p.109
Reaction of T-lymphocytes, designed to combat cell-associated microbes (e.g. Phagocytosed microbes and microbes in the cytoplasm of infected cells).
Cell-mediated immunity
Robbins Basic Pathology, 8th Ed p.109
Reaction of immune system against one’s own cells.
Autoimmunity
Robbins Basic Pathology, 8th Ed p.119
Results from activation of TH2 CD4+ helper T cells by environmental antigens, leading to the production of IgE antibodies, which become attached to mast cells.
Type I Hypersensitivity (immediate)
Robbins Basic Pathology, 8th Ed p.120
Caused by antibodies that bind to fixed tissue or cell surface antigens and promote phagocytosis and destruction of the coated cells or trigger pathologic inflammation in tissues.
Type II Hypersensitivity (Antibody-mediated)
Robbins Basic Pathology, 8th Ed p.120
Caused by antibodies binding to antigens to form complexes that circulate and may deposit in vascular beds and stimulate inflammation, secondary to complement activation.
Type III Hypersensitivity (immune complex mediated)
Robbins Basic Pathology, 8th Ed p.120
Cell-mediated immune responses in which T lymphocytes cause tissue injury, either by producing cytokines that induce inflammation and activate macrophages, or by directly killing cells.

Type II
Robbins Basic Pathology, 8th Ed p.120
A special form of graft rejection occuring in the setting where preformed antidonor antibodies are present in the circulation of the host before transplant. Occurs within minutes to a few hours after transplantation.
Hyperacute rejection
Robbins Basic Pathology, 8th Ed p.133
Rejection which occurs within days to weeks of transplantation in a nonimmunosuppressed host. Caused by both cellular and humoral immune mechanisms.
Acute rejection(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.133
Acute rejection most commonly seen within the first months after transplantation, typically accompanied by signs of renal failure. Extensive CD4+ and CD8+ T-cell infiltration with edema and mild interstitial hemorrhage.
Acute cellular rejection(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.133
Acute rejection caused by antidonor antibodies. May take the form of necrotizing vasculitis with endothelial cell necrosis, neutrophilic infiltration, deposition of antibody, complement, and fibrin, and thrombosis.
Acute humoral rejection(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.133
Rejection which present clinically months to years after transplantation with a progressive rise in serum creatinine levels. Dominated by arteriosclerosis, interstitial fibrosis and loss of renal parenchyma.
Chronic rejection(TOPNOTCH)Robbins Basic Pathology, 8th Ed p.133
