Prey specificity of predatory venoms

Biological Reviews, Volume 99, Issue 6, Page 2253-2273, December 2024.
ABSTRACT Venom represents a key adaptation of many venomous predators, allowing them to immobilise prey quickly through chemical rather than physical warfare. Evolutionary arms races between prey and a predator are believed to be the main factor influencing the potency and composition of predatory venoms.

Crotalus durissus collilineatus Venom Induces TNF‐α and IL‐10 Production in Human Peripheral Blood Mononuclear Cells

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014
Snake venom has been the subject of numerous studies in an attempt to find properties and biological effects that may be beneficial to man. In this study we evaluated in vitro the effects of Crotalus durissus terrificus (Cdt) and Crotalus durissus collilineatus (Cdc) venom in human peripheral blood mononuclear cells (PBMCs).

Snake venom toxins: Potential anticancer therapeutics

Journal of Applied Toxicology, Volume 44, Issue 5, Page 666-685, May 2024.
Abstract Snake venom contains a cocktail of compounds dominated by proteins and peptides, which make up the toxin. The toxin components of snake venom attack several targets in the human body including the neuromuscular system, kidney and blood coagulation system and cause pathologies. As such, the venom toxins can be managed and used for the treatment
