11173059caspase 1caspase 11.0interestingly caspase 1 formerly called interleukin 1_amp_#x3b2; converting enzyme is responsible for the cleavage of mature interleukin 1_amp_#x3b2; from its precursor and interleukin 1_amp_#x3b2; levels are increased in a

12060810caspase 1caspase 11.0in these in vivo models minocycline prevented completely the ischemia induced activation of microglia as well as the concomitant induction of caspase 1 and inos.  
12843244caspase 1caspase 11.0caspase 11 is a key regulator of caspase 1 and caspase 3 activation under pathological conditions.  
12843244caspase 1caspase 11.0the caspase 1 and caspase 3 like activities as well as the level of interleukin 1 beta were significantly reduced in the spinal cord of symptomatic caspase 11 / ;sod1 g93a mice compared with that of caspase 11 +/  
12843244caspase 1caspase 11.0activation of caspase 1 and caspase 3 in the spinal cords of mutant sod1 mice and als patients has been reported previously martin 1999 ; li et al. 2000 ; pasinelli et al. 2000 ; vukosavic et al. 2000 .  
12843244caspase 1caspase 11.0moreover inhibition of caspase s with peptide inhibitors or by introducing a dominant negative mutant of caspase 1 delayed the onset and progression of the disease symptoms in g93a sod1 g93a transgenic mice friedlander et al. 1997 ; li et al. 2000 suggesting the importance of caspase mediated apoptosis in the als 
12843244caspase 1caspase 11.0the possible involvement of both caspase 1 and caspase 3 in the pathogenesis of als strongly suggested the involvement of caspase 11 in this process because caspase 11 is a key upstream regulator of both caspase 1 and 3 under pathological con 
12843244caspase 1caspase 11.0 and caspase 3 in the pathogenesis of als strongly suggested the involvement of caspase 11 in this process because caspase 11 is a key upstream regulator of both caspase 1 and 3 under pathological conditions wang et al. 1998 beta il 1 beta maturation and resistant to lipopolysaccharide lps induced septic shock wang et al. 1998 .  
12843244caspase 1caspase 11.0in the present study we provide evidence that caspase 11 plays a critical role in caspase 1 and 3 activation during pathogenesis of g93a mice a mouse model of fals gurney et al. 1994 .  
12843244caspase 1caspase 11.0caspase 11 regulates caspase 1 and 3 activation in the spinal cords of g93a mice  
12843244caspase 1caspase 11.0activation of caspase 1 and caspase 3 in the spinal cord of presymptomatic g93a mice has been reported previously li et al. 2000 ~60 d of age consistent with reports of active caspase 1 being present in the spinal cords of g93a mice li et al. 2000 ; pasinelli et al. 2000 .  
12843244caspase 1caspase 11.0furthermore our analysis demonstrated a clear induction of full length caspase 1 expression starting from 60 d of age and continuing to increase as the disease progresses fig 1 a .  
12843244caspase 1caspase 11.0however no signs of caspase 1 and 3 activation were detected in the caspase 11 / ; g93a spinal cords data not shown .  
12843244caspase 1caspase 11.0these results imply that caspase 11 in addition to caspase 1 and 3 may be involved in regulating inflammatory reaction and/or apoptosis during the disease onset and progression of this mouse model of als.  
12843244caspase 1caspase 11.0because the lack of caspase 11 resulted in the significant inhibition of caspase 1 and caspase 3 activation our results suggest that caspase 1 and caspase 3 activation is not crucial for neurodegeneration in this mouse model of als.  
12843244caspase 1caspase 11.0our study cannot rule out however that the residual caspase activity in caspase 11 / background sufficient for neurodegeneration and caspases other than caspase 1 and caspase 3 may be involved in mediating neuronal degeneration in g93a mice.  
12843244caspase 1caspase 11.0we showed previously that introduction of dominant negative caspase 1 c281g mutant in g93a mice delayed the disease onset and progression friedlander et al. 1997 .  
12843244caspase 1caspase 11.0because caspase 1 interacts with caspase 11 wang et al. 1998 this dominant negative mutant of caspase 1 may act by inhibiting caspase 11.  
12843244caspase 1caspase 11.0however because the deletion of caspase 11 did not prevent neurodegeneration in the g93a mice it is possible that caspase 1c281g may act by inhibiting caspases other than caspase 1 11 or 3 or by another unknown gain of function process.

12843244caspase 1caspase 11.0eighty micrograms of the samples were also immunoblotted with monoclonal anti caspase 1 antibody for detection of full length caspase 1 c1fl and the active form active c1 and with anti active caspase 3 antibody active c3 . *igg h igg heavy chain; *nsp nonspecific.  
12843244caspase 1caspase 11.0the caspase 3 caspase 1 and caspase 11 like enzyme activities were measured using fluorogenic substrates acdevd amc devd acyvad amc yvad and acvehd amc vehd respectively in the lysates n = 4; mean _amp_#177; sd .  
12843244caspase 1caspase 11.0to examine whether caspase 11 indeed regulates caspase 1 and/or 3 in the spinal cord of g93a mice we crossed caspase 11 / and g93a mice and compared the profiles of caspase activities in the symptomatic day 120 spinal cord lysates of littermate caspase 11  
12843244caspase 1caspase 11.0consistent with the activation of caspase 1 and caspase 3 and the caspase 11 induction profile by immunoblot fig 1 a acyvad amc caspase 1 like acdevd amc caspase 3 like and acvehd amc caspase 11 like cleavage activities thornberry et al. 1997 ; kang et al. 2000 were elevated in the lumbar and thoracic spinal cords of g93a mice fig 1 b  
12843244caspase 1caspase 11.0in caspase 11 / ; g93a mice the absence of caspase 11 resulted in a significant reduction of caspase 3 and caspase 1 like activities as well as caspase 11 like activity fig 1 b .

12843244caspase 1caspase 11.0the evidence of activation of caspase 1 and 3 by caspase 11 in g93a mice prompted us to compare the inflammatory response and cell death in g93a spinal cords in the presence or absence of caspase 11.  
14739060caspase 1caspase 11.0the involvement of mitochondria and apoptosis in neuronal death is too revealed by a prolonged period of neuronal caspase activation especially caspase 1 [ 17 ].  
14739060caspase 1caspase 11.0ice [ 46 and 63 ] revealed an up regulation of gene related to an inflammatory process such as tnf_amp_#x3b1; gene resulting in glial activation together with change in apoptosis related gene such as caspase 1.  
15571972caspase 1caspase 11.0accordingly several studies showed that minocycline reduces the expression of inducible nitric oxide synthase and subsequent nitric oxide production as well as caspase 1 activity/expression and thereby prevents the formation of interleukin 1_amp_#x3b2; amin et al. 1996 ; chen et al. 2000 _amp_#x2014;5 mg/kg/d i.p.; du et al. 2001 _amp_#x2014;60 to 120 mg/kg p.o.; yrj

17597167caspase 1caspase 11.0the induction sequence showed that the proinflammatory cytokine il 1_amp_#x3b2; preceded both the antiinflammatory il 1ra and the synthesising enzyme caspase 1 see [41] .

17597167caspase 1caspase 11.0caspases have in common to exert apoptotic activity and caspase 1 was shown to be the mammalian homologue of ced 3 in the nematode caenorhabditis elegans [43] .  
17597167caspase 1caspase 11.0inhibition of caspase 1 activity was shown to prevent apoptotic cell death of cultured neurons [44] .  
17597167caspase 1caspase 11.0in addition to its inducible production in microglia see [41] caspase 1 is found constitutively in arcuate neurons see fig 2 co localised with _amp_#x3b1; melanocyte stimulating hormone _amp_#x3b1; msh [45] whereas both il 1ra and il 1ri were found to be expressed in vas
