Crotoxin, the major toxin from the rattlesnake Crotalus durissus terrificus, inhibits ³H-choline uptake in guinea pig ileum

Brazilian Journal of Medical and Biological Research, 2000
We examined the effect of crotoxin, the neurotoxic complex from the venom of the South American rattlesnake Crotalus durissus terrificus, on the uptake of ³H-choline in minces of smooth muscle myenteric plexus from guinea pig ileum.

Biological Roles of the Two Components of Crotoxin [PDF]

Proceedings of the National Academy of Sciences, 1971
Crotoxin, the Brazilian rattlesnake neurotoxin, generally behaves as a homogeneous protein; however, it is a molecular complex of an acidic and a basic protein. These can be separated after alkylation or acylation of the amino groups, or on carboxymethyl cellulose at pH 4, or on DEAE-cellulose in 6 M urea. The two proteins differ greatly in composition,

Immunotherapeutic potential of Crotoxin: anti-inflammatory and immunosuppressive properties

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018
For the past 80 years, Crotoxin has become one of the most investigated isolated toxins from snake venoms, partially due to its major role as the main toxic component in the venom of the South American rattlesnake Crotalus durissus terrificus.

Crystal Structure of Isoform CBd of the Basic Phospholipase A₂ Subunit of Crotoxin: Description of the Structural Framework of CB for Interaction with Protein Targets

Molecules, 2020
Crotoxin, from the venom of the South American rattlesnake Crotalus durissus terrificus, is a potent heterodimeric presynaptic β-neurotoxin that exists in individual snake venom as a mixture of isoforms of a basic phospholipase A2 (PLA2) subunit (CBa2 ...

Clinical, Laboratory, and Therapeutic Aspects of Crotalus durissus (South American Rattlesnake) Victims: A Literature Review

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Snakebite envenoming is a neglected public health issue in many tropical and subtropical countries. To diagnosis and treat snakebites may be challenging to health care personnel since sufficient information has not been yet provided. This review presents the clinical, therapeutic, and laboratory aspects of Crotalus durissus (South American rattlesnakes)

Crotalus durissus terrificus venom as a source of antitumoral agents

Journal of Venomous Animals and Toxins including Tropical Diseases, 2010
The basic knowledge on neoplasms is increasing quickly; however, few advances have been achieved in clinical therapy against tumors. For this reason, the development of alternative drugs is relevant in the attempt to improve prognosis and to increase ...

Crotalus durissus ruruima Snake Venom and a Phospholipase A2 Isolated from This Venom Elicit Macrophages to Form Lipid Droplets and Synthesize Inflammatory Lipid Mediators

Journal of Immunology Research, Volume 2019, Issue 1, 2019., 2019
Viper snake Crotalus durissus ruruima (Cdr) is a subspecies found in northern area of Brazil. Among the snakes of Crotalus genus subspecies, the venom of Cdr presents highest level of crotoxin, which is the major component of Crotalus snake venoms, formed by two subunits (crotapotin and a phospholipase A2 named CBr) and presents potent neurotoxic ...

Camelid Single-Domain Antibodies (VHHs) against Crotoxin: A Basis for Developing Modular Building Blocks for the Enhancement of Treatment or Diagnosis of Crotalic Envenoming

Toxins, 2018
Toxic effects triggered by crotalic envenoming are mainly related to crotoxin (CTX), composed of a phospholipase A2 (CB) and a subunit with no toxic activity (CA).

Crotoxin-Induced Mice Lung Impairment: Role of Nicotinic Acetylcholine Receptors and COX-Derived Prostanoids

Biomolecules, 2020
Respiratory compromise in Crotalus durissus terrificus (C.d.t.) snakebite is an important pathological condition. Considering that crotoxin (CTX), a phospholipase A2 from C.d.t. venom, is the main component of the venom, the present work investigated the
