Immunomodulatory activity of Tityus serrulatus scorpion venom on human T lymphocytes J. Venom. Anim. Toxins incl. Trop. Dis.
Casella-Martins,Andrea; Ayres,Lorena R; Burin,Sandra M; Morais,Fabiana R; Pereira,Juliana C; Faccioli,Lucia H; Sampaio,Suely V; Arantes,Eliane C; Castro,Fabiola A; Pereira-Crott,Luciana S.
Abstract Background Tityus serrulatus scorpion venom (TsV) contains toxins that act on K + and Na + channels and account for the venom’s toxic effects. TsV can activate murine peritoneal macrophages, but its effects on human lymphocytes have been poorly investigated. Considering that lymphocytes may play an important role in envenomation, we assessed whether TsV affects the expression of phenotypic (CD3, CD4, and CD8) and activation (CD69, CD25, and HLA-DR) markers, cell proliferation, and cytokine production in peripheral blood mononuclear cells. Methods Cytotoxicity of TsV was evaluated via the MTT assay. Cell proliferation, expression of phenotypic and activation markers, and release of cytokines were assessed using flow cytometry, after treatment...

Snake venom L-amino acid oxidases: an overview on their antitumor effects J. Venom. Anim. Toxins incl. Trop. Dis.
Costa,Tássia R; Burin,Sandra M; Menaldo,Danilo L; Castro,Fabíola A de; Sampaio,Suely V.
The L-amino acid oxidases (LAAOs) constitute a major component of snake venoms and have been widely studied due to their widespread presence and various effects, such as apoptosis induction, cytotoxicity, induction and/or inhibition of platelet aggregation, hemorrhage, hemolysis, edema, as well as antimicrobial, antiparasitic and anti-HIV activities. The isolated and characterized snake venom LAAOs have become important research targets due to their potential biotechnological applications in pursuit for new drugs of interest in the scientific and medical fields. The current study discusses the antitumor effects of snake venom LAAOs described in the literature to date, highlighting the mechanisms of apoptosis induction proposed for this class of proteins.
