Rhinovirus infections are common triggers of asthma exacerbations. Viruses can activate the inflammasome, resulting in processing and activation of caspase-1. This recruitment triggers production of interleukin (IL)-1β and IL-18, which have been implicated in asthma. Elucidating the involvement of the inflammasome and its compartments, such as caspase-1, in asthma exacerbations is warranted. Ge...

A series of 11 new substituted 1,5-dihydro-4,1-benzoxazepine derivatives was synthesised to study the influence methyl group in 1-(benzenesulphonyl) moiety, replacement purine by benzotriazole bioisosteric analogue, and introduction a bulky substituent at position 6 purine, on biological effects. Their inhibition against isolated HER2 studied structure–activity relationships have been confirmed...

Caspase-1 is an essential effector of inflammation, pyroptosis, and septic shock. Few caspase-1 substrates have been identified to date, and these substrates do not account for its wide range of actions. To understand the function of caspase-1, we initiated the systematic identification of its cellular substrates. Using the diagonal gel proteomic approach, we identified 41 proteins that are dir...

Apoptosis of cardiomyocytes is increased in heart failure and has been implicated in disease progression. The activation of "proapoptotic" caspases represents a key step in cardiomyocyte apoptosis. In contrast, the role of "proinflammatory" caspases (caspases 1, 4, 5, 11, 12) is unclear. Here, we study the cardiac function of caspase-1. Gene array analysis in a murine heart failure model showed...

objective(s):  apoptosis is a tightly regulated process and plays a crucial role in autoimmune diseases. because abnormalities in apoptosis are considered to be involved in the pathogenesis of systemic lupus erythematosus (sle), in present study we studied the apoptosis in t lymphocytes from iranian sle patientsat protein and gene expression levels for some molecules which are involved in apopt...

Caspase-1 is known to activate the proinflammatory cytokines IL-1β and IL-18. Additionally, it can cleave other substrates, including proteins involved in metabolism. Recently, we showed that caspase-1 deficiency in mice strongly reduces high-fat diet-induced weight gain, at least partly caused by an increased energy production. Increased feces secretion by caspase-1-deficient mice suggests tha...
