A Lyophilizable Nanoparticle Vaccine Specific for a Novel Linear Neutralizing Epitope in the α2-α3 Helices of Domain 3 of Lethal Factor from <i>Bacillus anthracis</i>. [PDF]

open access: yesToxins (Basel)
Anthrax remains a serious bioterrorism threat for which new and thermostable vaccines are needed. We previously demonstrated that immunization of rabbits with multiple-antigenic-peptide (MAP) vaccines elicit antibody (Ab) against the loop-neutralizing ...

The Anthrax Toxin Lethal Factor in Solution Does Not Have the Protein's Crystallized Structure. [PDF]

open access: yesToxins (Basel)
The bacterium Bacillus anthracis secretes three protein exotoxins: Protective Antigen 83 (PA83), Lethal Factor (LF), and Edema Factor (EF). A cleaved form of PA83 (PA63) aids LF and EF entry into the cytoplasm, which leads to anthrax-induced cell death ...

Asymmetric Cryo-EM Structure of Anthrax Toxin Protective Antigen Pore with Lethal Factor N-Terminal Domain. [PDF]

open access: yesToxins (Basel), 2017
The anthrax lethal toxin consists of protective antigen (PA) and lethal factor (LF). Understanding both the PA pore formation and LF translocation through the PA pore is crucial to mitigating and perhaps preventing anthrax disease.

Phage Display Analysis of Monoclonal Antibody Binding to Anthrax Toxin Lethal Factor [PDF]

open access: yesToxins (Basel), 2017
AVR1674 and AVR1675 are monoclonal antibodies (mAbs) that bind with high specificity to anthrax toxin lethal factor (LF) and lethal toxin (LTx).

Biochip for the Detection of Bacillus anthracis Lethal Factor and Therapeutic Agents against Anthrax Toxins. [PDF]

open access: yesMembranes (Basel), 2016
Tethered lipid bilayer membranes (tBLMs) have been used in many applications, including biosensing and membrane protein structure studies. This report describes a biosensor for anthrax toxins that was fabricated through the self-assembly of a tBLM with B.

Sequence analysis of the cDNA encoding for SpCTx: a lethal factor from scorpionfish venom (Scorpaena plumieri). [PDF]

open access: yesJ Venom Anim Toxins Incl Trop Dis, 2018
Background Lethal factors are multifunctional oligomeric proteins found in the venomous apparatus of Scorpaeniformes fish. These toxins elicit not only an array of biological responses in vitro but also cardiovascular disorders and strong hemolytic ...

Inhibitors of the Metalloproteinase Anthrax Lethal Factor. [PDF]

open access: yesCurr Top Med Chem, 2016
Bacillus anthracis, a rod shaped, spore forming, gram positive bacteria, is the etiological agent of anthrax. B. anthracis virulence is partly attributable to two secreted bipartite protein toxins, which act inside host cells to disrupt signaling pathways important for host defense against infection.

Molecular basis of specificity and deamidation of eIF4A by Burkholderia Lethal Factor 1. [PDF]

open access: yesCommun Biol, 2022
The crystal structure of the toxin from the pathogenic bacterium Burkholderia pseudomallei in complex with its target, human eIF4A, provides insights into substrate specificity and may facilitate the design of inhibitors for the treatment of melioidosis.

Anthrax toxin translocation complex reveals insight into the lethal factor unfolding and refolding mechanism. [PDF]

open access: yesSci Rep, 2021
Translocation is essential to the anthrax toxin mechanism. Protective antigen (PA), the binding component of this AB toxin, forms an oligomeric pore that translocates lethal factor (LF) or edema factor, the active components of the toxin, into the cell ...

CD4+ T Cells Targeting Dominant and Cryptic Epitopes from Bacillus anthracis Lethal Factor. [PDF]

open access: yesFront Microbiol, 2015
Anthrax is an endemic infection in many countries, particularly in the developing world. The causative agent, Bacillus anthracis, mediates disease through the secretion of binary exotoxins.
