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 ...

Venom gland transcriptomics for identifying, cataloging, and characterizing venom proteins in snakes
Toxicon, 2015Snake venoms are cocktails of protein toxins that play important roles in capture and digestion of prey. Significant qualitative and quantitative variation in snake venom composition has been observed among and within species. Understanding these variations in protein components is instrumental in interpreting clinical symptoms during human ...

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.

Toxicon, 2006 The funnel-web spider, Agelena labyrinthica, is widely distributed throughout Turkey. The objective of the present study was to describe the histological and functional fine structure of A. labyrinthica's venom gland by using light microscope, scanning (SEM) and transmission electron microscope (TEM).

Transcriptomic Analysis of the Spider Venom Gland Reveals Venom Diversity and Species Consanguinity [PDF]
Toxins, 2019 Selenocosmia jiafu (S. jiafu) has been recently identified as a new species of spider in China. It lives in the same habitat as various other venomous spiders, including Chilobrachys jingzhao (C. jingzhao), Selenocosmia huwena (S. huwena), and Macrothele raveni (M. raveni).

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.

Activation of Bothrops jararaca snake venom gland and venom production: A proteomic approach
Journal of Proteomics, 2013Viperidae venom glands have a basal-central lumen where the venom produced by secretory cells is stored. We have shown that the protein composition of venom gland changes during the venom production cycle. Here, we analyzed the venom gland proteins during the venom production cycle by proteomic approach. We identified specific proteins in each stage of

Epidermal secretions and the evolution of venom glands in fishes
Toxicon, 1973Epidermal secretory cells of fishes are of two types, one type elaborating proteinaceous material and the other type secreting mucus. Epidermal toxins (crinotoxins and venoms) are produced by the protein-elaborating cells. Venoms appear to have evolved from crinotoxins. Crinotoxic fishes tend to have reduced squammation.

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 ...
