1. Etiology
1. Etiology
Knowledge of etiology remains the backbone:
Disease diagnoses Understanding the nature of diseases Treatment of diseases.
While much still needs to be uncovered to link abnormal genes and the expression of disease, gone are the time when the mechanisms of most diseases were unknown? or obscure? or mysterious?
Depleted glycogen. Reduced intracellular pH: Lactic acid and
inorganic phosphate. Mitochondrial damage Clumping of nuclear chromatin.
Four biochemical themes
in cell and tissues. FUNCTIONAL CONSEQUENCES:
Functional consequences of the morphologic changes, as observed clinically (clinico-pathological correlation, CPC ).

Overview
Immune system: A Two-edged sword: responsible for defending us against
The fundamental defect in SLE is a failure to maintain self-tolerance.
A large number of autoantibodies is produced that can damage tissues either directly or in the form of immune complex deposits
Diseases of Autoimmunity
Tolerance (unresponsiveness) to self-antigens is a fundamental property of the immune system, breakdown is the basis of autoimmune diseases
Etiology and Pathogenesis
2. Nongenetic Factors (1) Most patients treated with procainamide (普鲁 卡因胺) for more than 6 months develop ANAs (抗 核抗体）and 20% appear SLE. (2) Sex hormones, especially estrogens. (3) Exposure to ultraviolet light.
2. Other Autoantibodies
Antibodies against blood cells Antiphospholipid（磷脂） antibodies
Etiology and Pathogenesis
1. Genetic Factors
(1) There is a high rate of concordance (25%) in monozygotic twins versus dizygotic twins (1% to 3%).
the countless pห้องสมุดไป่ตู้thogenic microbes or tumors hypersensitive or abnormal reaction is the cause of some diseases
The Common Types of the Diseases of Immunity
Systemic Lupus Erythematosus
(SLE)
Characteristics:
1. Predominantly in young women.
2. Mainly conducted by humoral immunity.
3. Multiple organs damage, multisystem autoimmune disease
Antibodies include:
1. Antinuclear Antibodies
(1) antibodies to DNA
(2) antibodies to histones
(3) antibodies to nonhistone proteins bound to RNA
(4) antibodies to nucleolar antigens
1. LE body: ANAs attack the damaged cell’s nuclear, the cell lost its chromatin pattern, and become homogeneous, to produce so-called LE body (hematoxylin body). The neutrophil or macrophage that has engulfed the LE body is referred as to LE cell
(2) Family members have an increased risk of developing SLE. And up to 20% of clinically unaffected first-degree relatives may reveal autoantibodies.
(3) Positive association between SLE and polymorphism of HLA-DQ locus.
