Clostridium perfringens phospholipase C (PLC), also called alpha-toxin, is the major virulence factor in the pathogenesis of gas gangrene. The toxic activities of genetically engineered alpha-toxin variants harboring single amino-acid substitutions in three loops of its C-terminal domain were
Clostridium perfringens alpha-toxin (370 residues) is a major virulence factor in the pathogenesis of gas gangrene. The toxin is composed of an N-terminal domain (1-250 residues) where lies the catalytic site and a C-terminal domain (251-370 residues), the Ca(2+)-binding domain, responsible for
BACKGROUND
Critical limb ischemia (CLI) is a severe peripheral arterial disease, characterized by rest pain, ulcers and gangrene in the legs. Gas6 is a vitamin K-dependent protein, which binds and activates the tyrosine kinase receptor Axl. Gas6-mediated Axl-signaling influences endothelial
A characteristic feature of gas gangrene with Clostridium perfringens (C. perfringens) is the absence of neutrophils within the infected area and the massive accumulation of neutrophils at the vascular endothelium around the margins of the necrotic region. Intravenous injection of C. perfringens
Chemotherapy, alone or in association with radiation therapy, has represented the cornerstone of cancer treatment for decades. However, in the last several years, an unprecedented progress in the understanding of cancer biology and the discovery of novel therapeutic targets have led to a paradigm
