Venom production in snake venom gland cells cultured in vitro
Toxicon, 1989The venom gland cells from a Ghanaian specimen of Bitis gabonica were established in tissue culture for over seven months. During this time the cells maintained their original morphology and divided actively. Tests for the synthesis of venom using an immuno peroxidase technique (on the cells) were strongly positive and tests for the secretion of venom ...

Viperid venom glands with defective venom production. Morphological study
Toxicon, 2013The venom of viperid snakes is collected monthly at Butantan Institute for research purposes and production of antivenoms. Here we describe histological and ultrastructural changes on Crotalus durissus terrificus and Bothrops sp. venom glands with defective venom production.

RNA-Sequencing of Snake Venom Glands
2019Next-generation sequencing (NGS), particularly RNA-sequencing (RNA-Seq) technique, allows detection and quantification of different RNA transcripts in a tissue sample, and in our case toxin transcripts from snake venom glands. Using this approach, novel toxin transcripts can be detected and abundancies of different isoforms of each toxin measured.

Combined snake venomics and venom gland transcriptomic analysis of Bothropoides pauloensis
Journal of Proteomics, 2012Unraveling the repertoire of venom toxins of Bothropoides pauloensis was assessed by snake venomics and venom gland transcriptomic surveys. Both approaches yielded converging overall figures, pointing to metalloproteinases (~37%), PLA(2)s (26-32%), and vasoactive (bradykinin-potentiating) peptides (12-17%) as the major toxin classes.

Journal of Morphology, 2000
A combination of histology, whole muscle force physiology, glycogen depletion, and venom expulsion analyses using transonic probes to measure venom flow and fluid pressure transducers to measure venom pressure was performed on the m. compressor glandulae and m. pterygoideus glandulae. The m.

The accessory gland in the venom apparatus of viperid snakes
Toxicon, 1965Abstract The accessory gland of vipers and pitvipers straddles the connexion from the main gland to the secondary duct that leads to the fang. The accessory gland is shown to consist of two portions differing in histological and histochemical appearance, in structural arrangement, and probably in function.

Venoms and Venom Glands of Marine Molluscs
1984The phylum Mollusca, consisting of about 100,000 living species, is divided into seven classes. Venom glands occur in molluscs belonging to the classes Gastropoda and Cephalopoda. Toxins acquired from the environment, such as paralytic shellfish poisons, are found in certain Pelecypoda (bivalves), but also some gastropods have been found to accumulate ...

Inducible antibacterial response of scorpion venom gland
Peptides, 2007Innate immunity is the first line defense of multicellular organisms that rapidly operates to limit aggression upon exposure to pathogen microorganisms. Although the existence of some antibacterial peptides in scorpion venoms suggests that venom gland could be protected by these effector molecules, antibacterial activity of venom itself has not been ...

The Venom Glands of Snakes and Venom Secretion
1979The origin of snake venom has been variously ascribed to different body organs. The idea that the venom virulence depends on the snake’s anger led to a famous controversy in the late 17 th century. Redi, an Italien biologist, ascribed the dangerous nature of the venom to the yellow liquid issuing from the fangs, while the French chemist, Charas ...

Melanin deposits associated with the venom glands of snakes
Journal of Morphology, 1978AbstractMelanin deposits in the heads of both true vipers (Viperinae) and pit vipers (Crotalinae) are concentrated over the dorsal and dorsolateral aspects of the venom glands. This pigment may occur in any or all of six sites which include the epidermis, dermis, tissues covering the venom glands, and the interior of the glands themselves.
