Vipera berus venom protein toxins

Vipera berus venom protein toxins represent a complex mixture of enzymes and non-enzymatic proteins secreted by the common European adder. The venom's primary constituents include phospholipase A2 (PLA2), snake venom metalloproteinases (SVMPs), snake venom serine proteinases (SVSPs), and C-type lectin-like proteins (UniProt, 2023). These toxins act synergistically to disrupt physiological processes, primarily targeting the hematological and cardiovascular systems, leading to symptoms such as local edema, hemorrhage, and systemic coagulopathy (StatPearls, 2023). While the venom is predominantly hemotoxic, certain populations exhibit neurotoxic activity due to the presence of vaspin or ammodytoxin-like PLA2s (PubMed, 2022). Therapeutic management of envenomation relies on the administration of specific antivenoms, such as ViperaTab, which contain purified Fab fragments that neutralize the toxins' enzymatic and binding activities (NIH, 2023). Understanding the proteomic profile of these toxins is crucial for improving the efficacy and safety of antivenom treatments. The venom's composition can vary geographically, which influences the clinical presentation and the required antivenom dosage.
