T Cell Targeting by Anthrax Toxins: Two Faces of the Same Coin

open access: yesToxins, 2011
Bacillus anthracis, similar to other bacterial pathogens, has evolved effective immune evasion strategies to prolong its survival in the host, thus ensuring the unchecked spread of the infection.

Role of the N-Terminal Amino Acid of Bacillus anthracis Lethal Factor in Lethal Toxin Cytotoxicity and Its Effect on the Lethal Toxin Neutralization Assay [PDF]

open access: yesClinical and Vaccine Immunology, 2008
ABSTRACT The cytotoxic activity of lethal factor (LF), a critical reagent used in the cell-based lethal toxin neutralization assay to assess anthrax vaccines, was shown to depend on the identity of its N-terminal amino acid, which plays a role in the targeting of LF to the proteasome for degradation.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

open access: yesFEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

Inhibition of development of Shiga toxin-converting bacteriophages by either treatment with citrate or amino acid starvation [PDF]

open access: yes, 2012
Objectives: Shiga toxin–producing Escherichia coli (STEC) are pathogenic strains, whose virulence depends on induction of Shiga toxin–converting prophages and their subsequent lytic development.

Synergistic Action of Staphylococcus aureus α-Toxin on Platelets and Myeloid Lineage Cells Contributes to Lethal Sepsis

open access: yesCell Host and Microbe, 2015
Summary Multi-organ failure contributes to mortality in bacterial sepsis. Platelet and immune cell activation contribute to organ injury during sepsis, but the mechanisms by which bacterial virulence factors initiate these responses remain poorly defined.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

open access: yesFEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Anthrax Lethal Toxin-Induced Gene Expression Changes in Mouse Lung

open access: yesToxins, 2011
A major virulence factor of Bacillus anthracis is the anthrax Lethal Toxin (LeTx), a bipartite toxin composed of Protective Antigen and Lethal Factor. Systemic administration of LeTx to laboratory animals leads to death associated with vascular leakage ...
