3.4.22.51 evolution the O-GlcNAc moieties constitute a common epitope between cruzipain and either myosin or other cardiac O-GlcNAc-containing proteins 718182 3.4.22.51 malfunction cruzain-deficient Trypanosoma cruzi rapidly activates host macrophages via NF-kB P65 and is unable to survive intracellularly within macrophages. No significant IL-12 expression occurs in macrophages infected with wild-type Trypanosoma cruzi and treated with lipopolysacchrides and brefeldin A, confirming impairment of macrophage activation pathways 718307 3.4.22.51 metabolism the enzyme is expressed by the protozoan parasite Trypanosoma cruzi during Chagas disease infection 752755 3.4.22.51 physiological function cruzain is the major cysteine protease involved in the survival of the parasite Trypanosoma cruzi 752406 3.4.22.51 physiological function cruzipain promotes Trypanosoma cruzi adhesion to Rhodnius prolixus midgut -, 732673 3.4.22.51 physiological function infection with wild-type parasites appears to induce cruzain-mediated proteolysis of NF-kappaB P65 leading to unresponsiveness of the host macrophage during early 60 min of infection. This immune evasion mechanism may be critical for Trypaosoma cruzi survival during early natural infection with a low number of trypmastigotes. The signaling factor NF-kappaB P65 colocalizes with cruzain on the cell surface of intracellular wild-type parasites, and is proteolytically cleaved. Transcription factor NF-kappaB P65 is translocated to the nucleus and activated only in macrophages infected with cruzain-deficient parasites 718307 3.4.22.51 physiological function key enzyme for the survival and propagation of this parasite lifecycle 755010 3.4.22.51 physiological function the enzyme is the etiological agent of Chagas disease 752931
