Hemispheres injected with tau oligomers were found to have increased levels of caspase-9 activation (Lasagna-Reeves et al., 2011) PubMed:28420982
Suggestively, as tau oligomers concentrate at the mitochondrial membrane, cytochrome C is released, leading to caspase-9 activation via a complex with apoptotic-peptidase activating- factor-1 (Apaf-1; Li et al., 1997) PubMed:28420982
Indeed, inflammasomes (which induce pyroptosis through caspase 1 or caspase 11 activation) and apoptosomes (which activate caspase 9 in response to cytochrome c release from mitochondria) are two mechanisms by which compromised cells are eliminated. PubMed:23702978
CARD8 has multiple functions in regulating apoptosis, one of which is to directly bind to procaspase 9 and to suppress its activation109. PubMed:23702978
By contrast, nitrosylation of caspase 9 inhibits its function94. Similarly, caspase 1 can be inhibited by nitrosylation95, which suggests that modification by reactive molecules is a general mechanism for the regulation of caspase activity. PubMed:23702978
