Edema Induced by a Crotalus durissus terrificus Venom Serine Protease (Cdtsp 2) Involves the PAR Pathway and PKC and PLC Activation. [PDF]

Int J Mol Sci, 2018
Snake venom serine proteases (SVSPs) represent an essential group of enzymatic toxins involved in several pathophysiological effects on blood homeostasis. Some findings suggest the involvement of this class of enzymatic toxins in inflammation.

Peptidase activities in Crotalus durissus terrificus semen [PDF]

REPRODUCTION, 2008
AbstractTo understand the role of peptidases in seminal physiology of Crotalus durissus terrificus, activity levels of representative enzymes in semen and their sensitivities to inhibitors, cofactors, and peptide hormones were evaluated. The existence of seminal fractions and the association of peptidases with these fractions were also characterized ...

Electrical field-induced contractions on Crotalus durissus terrificus and Bothrops jararaca aortae are caused by endothelium-derived catecholamine. [PDF]

PLoS One, 2018
Endothelium is the main source of catecholamine release in the electrical-field stimulation (EFS)–induced aortic contractions of the non- venomous snake Panterophis guttatus.

Age-related biological activity of South American rattlesnake (Crotalus durissus terrificus) venom

Journal of Venomous Animals and Toxins including Tropical Diseases, 2003
An in vitro and in vivo comparative study was performed on the effects of Crotalus durissus terrificus venoms from a mother and its 15 newborns. The venoms were tested for protein content, lethality, proteolytic, myotoxic, hemorrhagic, and phospholipase ...

Role of crotoxin, a phospholipase A2 isolated from Crotalus durissus terrificus snake venom, on inflammatory and immune reactions [PDF]

Mediators of Inflammation, 2001
Background: Crotoxin (CTX) is a potent neurotoxin from Crotalus durissus terrificus snake venom (CdtV) composed of two subunits: one without catalytic activity (crotapotin), and a basic phospolipase A2.

The Evolutionary Implications of Hemipenial Morphology of Rattlesnake Crotalus durissus terrificus (Laurent, 1768) (Serpentes: Viperidae: Crotalinae). [PDF]

PLoS ONE, 2013
Most amniotes vertebrates have an intromittent organ to deliver semen. The reptile Sphenodon and most birds lost the ancestral penis and developed a cloaca-cloaca mating.
