Recently, there has been a major push toward the development of next-generation treatments against snakebite envenoming. However, unlike current antivenoms that rely on animal-derived polyclonal antibodies, most of these novel approaches are reliant on an in-depth understanding of the over 2000 known snake venom toxins. Indeed, by identifying similarities (i.e., conserved epitopes) across these different toxins, it is possible to design cross-reactive treatments, such as broadly-neutralising antibodies, that target these similarities. Therefore, in this project, we built an automated pipeline that generates sequence and structural distance matrices and homology trees across all available snake venom toxin sequences and structures. To facilitate analysis, we also developed a user-friendly and high-throughput visualisation tool, coined "Venom TOxin CluStering" (V-ToCs). This tool allows researchers to easily investigate sequence and structure patterns in snake venom toxins for a wide array of purposes, such as elucidating toxin evolution, and will also hopefully help guide the discovery and development of increasingly broadly-neutralising antivenoms in the near future.

Angiogenesis, the formation of new blood vessels from pre-existing vasculature, is a crucial process in both physiological and pathological contexts, including cancer. Phospholipases A (PLAs), enzymes found in snake venoms, have attracted attention due to their potential antiangiogenic properties. In this study, we explored the antiangiogenic effects of PLA isoforms isolated from Bothrops diporus venom using a combination of in vivo and ex vivo models.

Much less common is snake venom ophthalmia secondary to eye exposure from spitting snakes. This paper reports an unusual case of systemic envenomation via the ocular route of a 14-year old male from the Philippines.

Background: Inflammation plays a critical role in the pathogenesis of limb injury caused by snakebite. Investigating its regulatory mechanisms and intervention strategies may help identify effective treatments. Recent studies have shown that pyroptosis exacerbates organ damage by amplifying inflammatory responses.

Snake envenoming is a relevant public health issue, especially in tropical regions worldwide. Bothrops venom is essential for antivenom production in Brazil; however, the impacts of hepatic neoplasms on venom composition remain unexplored. This study aimed to evaluate whether hepatic neoplasms and/or cysts influence the biochemical profile and enzymatic activity of venoms from five Bothrops species.

To evaluate the efficacy and clinical application value of mouse nerve growth factor combined with neostigmine in the treatment of nerve injury in patients bitten by Bungarus multicinctus by a prospective single-blind controlled clinical study. In June 2020, a prospective, single-blindness, randomized grouping method was used to select patients with bungarus multicinctus saurogobio dabryi subsp. dabryi bite injuries admitted to the Emergency Department of Ganzhou People's Hospital in Jiangxi Province as the study subjects.
