INIBITORI DELLACETILCOLINESTERASI (AChE) 2a) reversibili, legame covalente
3
INIBITORI DELLACETILCOLINESTERASI (AChE) 2b) reversibili, legame covalente
4
DFP (DIIDROPROPILFLUOROFOSFATO) PARATHION MALATHION CLORPIRIFOS INIBITORI DELLACETILCOLINESTERASI (AChE) 3a) irreversibili: insetticidi organofosforici
5
INIBITORI DELLACETILCOLINESTERASI (AChE) 3b) irreversibili, gas nervini
9
Anti-AChR antibodies cross-link AChRs Cross-linked AChRs are endocytosed more rapidly than normal Internalized AChRs are degraded Fewer AChRs remain on the Post-Junctional membrane RESULT: Less efficient neuromuscular transmission
10
Complement binds to the Antibody-AChR complex Membrane-attack complex (MAC) forms on the membrane The post-junctional membrane is damaged Fewer post-synaptic membrane folds Reduced numbers of AChRs Widened synaptic cleft RESULT: Less efficient neuromuscular transmission
