Inter-individual variability in equine antibody responses to African snake venoms follows heavy-tailed distributions with implications for antivenom production

  Inter-individual variability in equine antibody responses to African snake venoms follows heavy-tailed distributions with implications for antivenom production Abstract Variability in the antibody response of horses used for snake antivenom manufacture is well recognized, yet its statistical structure and implications for industrial productivity remain poorly characterized. In this study, we quantified antivenom antibody titers by ELISA in a cohort of 14 horses immunized with venoms from the clinically most important snakes in sub-Saharan Africa. To integrate antibody levels with plasma availability, we calculated the Cumulative Plasma Productivity (CPP) by converting individual plasma volumes into titer-corrected equivalents and sequentially pooling these volumes according to their corrected contribution. Distributional analysis revealed right-skewed, heavy-tailed patterns better approximated by a log-normal model than by a strict Pareto (power-law) form, with approximately 20–3...

Transcriptomic and Proteomic Study on Animal Venom: Looking Forward

Transcriptomic and proteomic studies concerning venom and venom glands have provided major breakthroughs in the characterization and knowledge of global crude venom compositions and have also allowed for the identification of new toxins and activities. Venom gland transcriptomes (mRNA) and proteomes (proteins) share a high degree of concordance regarding the major toxins produced, meaning the most heavily transcribed genes in the gland generally correspond to the most abundant proteins in the venom. These approaches are based heavily on specific techniques that allow for in-depth characterization and knowledge of global crude venom compositions like DNA sequencing and mass spectrometry, respectively. However, the transcriptome–proteome relationship is not perfectly linear, with studies often showing that venom gland transcriptomes contain a larger, more diverse array of “potential” toxin transcripts, while the proteome reflects only the “actual” translated products identified [1,2,3,4,5,6,7,8,9].
