Apoptotic TNF-family pathways
Members of the tumour necrosis factor ligand family (TNFs) induce both apoptotic and anti-apoptotic pathways. TNFs transduce cellular responses through activation of different TNF-receptors (TNFRs) , , .
Different TNF/TNFRs may activate some pro-apoptotic proteins (e.g. members of the cysteine-aspartic acid protease (caspase) family) or inhibit some anti-apoptotic proteins (e.g. members of the Bcl-2 family). Thus, TNF/TNFRs exert influence on apoptosis via caspase cascade and via mitochondrial proteins .
Apoptotic signals from TNFR superfamily, member 1A ( TNF-R1 ) , TNFR superfamily, member 12 ( DR3 ) , TNFR superfamily, member 10a ( DR4 ) , TNFR superfamily, member 10b ( DR5 )  and, possibly, TNFR superfamily, member 21 ( DR6 )  are mediated by TNFRSF1A-associated via death domain ( TRADD ) and/or Fas (TNFRSF6)-associated via death domain ( FADD ). Receptor TNFR-interacting serine-threonine kinase 1 ( RIPK1 ) may participate in this signal transduction as well .
TNF-alpha/ TNFR superfamily, member 1B ( TNF-R2 ) signal transduction is mediated by a complex of intracellular signaling molecules including TNF receptor-associated factor 2 ( TRAF2 ) and RIPK1 , .
Adaptor proteins, such as FADD, TRADD and RIPK1 domain containing adaptor with death domain ( RAIDD ) transmit an activation signal to effectors caspases Caspase-2, -8, and -10 .
In other pathways, TNF/TNFRs' signal transduction is influenced via inhibition of anti-apoptotic protein members of the Bcl-2 and IAP families; e.g. B-cell CLL/lymphoma 2 ( Bcl-2 ) and BCL2-like 1 ( Bcl-XL ) baculoviral IAP repeat-containing 2 ( c-IAP1 ), baculoviral IAP repeat-containing 4 ( XIAP ).
For example, TNF superfamily, member 6 ( LIGHT )/ TNFR superfamily, member 3 ( LTBR ) signal transduction are mediated by a complex of intracellular signaling molecules including TRAF2, TNF receptor-associated factor 2 ( TRAF3 ), c-IAP1 and diablo homolog ( Smac/Diablo ) . Smac/Diablo inhibits activity of anti-apoptotic proteins c-IAP1 and XIAP .
Nerve growth factor, beta polypeptide ( NGF )/ TNFR superfamily, member 16 ( NGFR ) apoptotic signal may be mediated via different mechanisms. One such mechanism is an activation of nerve growth factor receptor associated protein 1 ( NADE ) .
TNF superfamily, member 7 ( CD70 )/ TNFR superfamily, member 7 ( CD27 ) and TNF superfamily, member 18 ( TNFSF18 )/ TNFR superfamily, member 18 ( GITR ) signal transductions are mediated by a CD27-binding (Siva) protein ( CD27BP ) , . CD27BP induces apoptosis via inhibition of anti-apoptotic proteins Bcl-2 and Bcl-XL , .
