Highlights in the knowledge of brown spider toxins

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2017
Brown spiders are venomous arthropods that use their venom for predation and defense. In humans, bites of these animals provoke injuries including dermonecrosis with gravitational spread of lesions, hematological abnormalities and impaired renal function.

Prospecting Local Treatments Used in Conjunction with Antivenom Administration Following Envenomation Caused by Animals: A Systematic Review

open access: yesToxins, 2023
Envenomation caused by venomous animals may trigger significant local complications such as pain, edema, localized hemorrhage, and tissue necrosis, in addition to complications such as dermonecrosis, myonecrosis, and even amputations.

Unwanted disorders and xenogeneic graft‐versus‐host disease in experimental immunodeficient mice: How to evaluate and how to report

open access: yesAnimal Models and Experimental Medicine, Volume 8, Issue 1, Page 20-29, January 2025.
Xenograft‐bearing immunodeficient mice are susceptible to developing unwanted disorders primarily irrelevant to nature of the xenografted tumor; and if get involved with such disorders, they do not produce reliable results, inevitably confounding the research outputs.

Biochemical Characterization, Action on Macrophages, and Superoxide Anion Production of Four Basic Phospholipases A2 from Panamanian Bothrops asper Snake Venom

open access: yesBioMed Research International, Volume 2013, Issue 1, 2013., 2013
Bothrops asper (Squamata: Viperidae) is the most important venomous snake in Central America, being responsible for the majority of snakebite accidents. Four basic PLA2s (pMTX‐I to ‐IV) were purified from crude venom by a single‐step chromatography using a CM‐Sepharose ion‐exchange column (1.5 × 15 cm).

Feasibility of using a combination of staphylococcal superantigen‐like proteins 3, 7 and 11 in a fusion vaccine for Staphylococcus aureus

open access: yesImmunology &Cell Biology, Volume 102, Issue 5, Page 365-380, May‐June 2024.
This study demonstrates that three secreted immune evasion factors from the staphylococcal superantigen‐like (SSL) protein family—SSL3, 7 and 11—can be successfully fused into a polyprotein. Mice immunized with a functionally inactive version of the polyprotein in the squalene‐based adjuvant (AddaVax), but not the equivalent amount of the individual ...

Platelet participation in the pathogenesis of dermonecrosis induced by Loxosceles gaucho venom [PDF]

open access: yes, 2015
Loxosceles gaucho spider venom induces in vitro platelet activation and marked thrombocytopenia in rabbits. Herein, we investigated the involvement of platelets in the development of the dermonecrosis induced by L.

Staphylococcus aureus alpha toxin suppresses effective innate and adaptive immune responses in a murine dermonecrosis model. [PDF]

open access: yesPLoS ONE, 2013
An optimal host response against Staphylococcus aureus skin and soft tissue infections (SSTI) is dependent on IL-1β and IL-17 mediated abscess formation.

Systemic Loxoscelism, Less Frequent but More Deadly: The Involvement of Phospholipases D in the Pathophysiology of Envenomation

open access: yesToxins, 2022
Bites of Loxosceles spiders can lead to a set of clinical manifestations called loxoscelism, and are considered a public health problem in many regions. The signs and symptoms of loxoscelism are divided into cutaneous and systemic forms.

Effect of Indian Polyvalent Antivenom in the Prevention and Reversal of Local Myotoxicity Induced by Common Cobra (Naja naja) Venom from Sri Lanka In Vitro

open access: yesToxins, 2021
Bites by many Asiatic and African cobras (Genus: Naja) cause severe local dermonecrosis and myonecrosis, resulting in permanent disabilities. We studied the time scale in which two Indian polyvalent antivenoms, VINS and Bharat, remain capable of ...

Brown Spider Venom Phospholipase-D Activity upon Different Lipid Substrates

open access: yesToxins, 2023
Brown spider envenomation results in dermonecrosis, characterized by an intense inflammatory reaction. The principal toxins of brown spider venoms are phospholipase-D isoforms, which interact with different cellular membrane components, degrade ...
