Immune System
Self Recognize
Goal : Recognition known intruders, Elimiation, Learn
Produce specific molecles to eliminate dangerous (Antibody, antigen)
Four Layer
Outer barrier
Physiological barrier - PH level or temperature
innate immune system - macrophage
If all evade, acquired immune response
Information of antibody have
to be encoded to the gene
Lymphocyte - find matching
receptor and relevent anty body
--> 特定目標攻擊 non-self
少量的gene (排除方式) 來產生抗體
V-D-J-C genes
heavy (4800) light (400) --> 1,920,000 種可能
humoral immunity
T cell --> cell-mediated immunity
--> 給予部分資訊 --> spot peptide --> 殺掉
--> 可能進行無差別攻擊
B cell --> 詳細看antibody 的部分
Self or non-self
病毒 RNA --> 影響動物 --> interferons 抵抗
是病毒種類儲存資訊(peptide) 常出現多存
B cell - receptor proteins known as immunoglobulins
T cells - receptor protein --> alpha-beta --> mixture of gene segments --> learns
T cells -gamma-delta
Fault-Tolerance
Masking type
- error detect 不多
-vote 決定結果
Recovery - error detect followed by error recovery
結構 fault aviodance --> removal --> tolerance
Software - backward error recovery
Hardware - standby spare
Testing 生產資訊
-需要的information - input, excitation, current state and output --> constract antibody
-- genetic algorithm --> 輸入進去 --> 因此免疫系統"天生就"
擁有這些資訊
-- content addressable memory
-- inhibitor --> sensing logic --> 阻止/只讓特定的運行
-- more decentralize????? --> 想想看有沒有創新
