Autologous fibroblasts for the treatment of cutaneous loxoscelism: First experience

International Wound Journal, Volume 16, Issue 6, Page 1503-1505, December 2019., 2019
Abstract Several treatments have been described for cutaneous loxoscelism (CL), but the quality of available evidence is insufficient for the elaboration of a therapeutic consensus. Dapsone has shown beneficial effects on stopping the inflammatory phenomenon and accelerating the recovery. It is recommended to start dapsone once the visceral involvement

Social media filtering of sensationalistic news on spiders—A global overview

People and Nature, Volume 7, Issue 7, Page 1687-1696, July 2025.
Abstract The interplay between traditional and social media is a critical aspect of information dissemination. Acting as news filters, social media platforms can amplify the visibility of specific content and shape emotions towards wildlife. Widely feared animals (e.g.

Loxoscelism: Cutaneous and Hematologic Manifestations

Advances in Hematology, Volume 2019, Issue 1, 2019., 2019
Background. Brown recluse spider (BRS) envenomation can lead to significant morbidity through severe local reaction and systemic illness including acute hemolytic anemia, rhabdomyolysis, disseminated intravascular coagulopathy (DIC), and even death. We aim to describe the clinical features and the roles of antibiotics and steroids in the treatment of ...

Venom from Bothrops lanceolatus, a Snake Species Native to Martinique, Potently Activates the Complement System

Journal of Immunology Research, Volume 2018, Issue 1, 2018., 2018
Bothrops lanceolatus snake venom causes systemic thrombotic syndrome but also local inflammation involving extensive oedema, pain, and haemorrhage. Systemic thrombotic syndrome may lead to fatal pulmonary embolism and myocardial and cerebral infarction. Here, we investigated the ability of B.

Loxosceles venom Sphingomyelinase D activates human blood leukocytes: Role of the complement system

, 2018
Envenomation by Loxosceles spiders can result in severe systemic and local reactions, which are mainly triggered by Sphingomyelinase D (SMase D), a toxic component of Loxosceles venom.

Discovery of broadly‐neutralizing antibodies against brown recluse spider and Gadim scorpion sphingomyelinases using consensus toxins as antigens

Protein Science, Volume 33, Issue 3, March 2024.
Abstract Broadly‐neutralizing monoclonal antibodies are becoming increasingly important tools for treating infectious diseases and animal envenomings. However, designing and developing broadly‐neutralizing antibodies can be cumbersome using traditional low‐throughput iterative protein engineering methods. Here, we present a new high‐throughput approach

Assessing the Proteomic Activity of the Venom of the Ant Ectatomma tuberculatum (Hymenoptera: Formicidae: Ectatomminae)

Psyche: A Journal of Entomology, Volume 2018, Issue 1, 2018., 2018
Ectatomma tuberculatum has one of the most toxic venoms known among ants but there is no detailed study on its characteristics. In light of this, knowing the venom’s chemical composition is of paramount importance in order to obtain information about the mechanisms of its components.

Transcriptome analysis of Loxosceles laeta (Araneae, Sicariidae) spider venomous gland using expressed sequence tags

BMC Genomics, 2008
Background The bite of spiders belonging to the genus Loxosceles can induce a variety of clinical symptoms, including dermonecrosis, thrombosis, vascular leakage, haemolysis, and persistent inflammation.

Study of anti-loxosceles serum action on hemolytic and ulcero-necrotic cutaneous effects of Loxosceles laeta venom Estudio de la acción del suero antiloxoscélico sobre los efectos hemolíticos y ulcero-necróticos cutáneos producidos por el veneno de la ara [PDF]

, 1994
The action of an anti-loxosceles serum on in vitro human red blood cell hemolysis and on the development of ulcero-necrotic lesions in rabbit skin, induced by loxosceles laeta venom, was studied.

Specificity of Loxosceles α clade phospholipase D enzymes for choline-containing lipids: Role of a conserved aromatic cage.

PLoS Computational Biology, 2022
Spider venom GDPD-like phospholipases D (SicTox) have been identified to be one of the major toxins in recluse spider venom. They are divided into two major clades: the α clade and the β clade.
