Role and Regulation of Clp Proteases: A Target against Gram-Positive Bacteria

Bacteria, 2023
Bacterial proteases participate in the proteolytic elimination of misfolded or aggregated proteins, carried out by members of the AAA+ protein superfamily such as Hsp100/Clp, Lon, and FtsH. It is estimated that the Clp and Lon families perform around 80%

Entry of spores into intestinal epithelial cells contributes to recurrence of Clostridioides difficile infection

Nature Communications, 2021
Spores produced by Clostridioides difficile during infection are important for the recurrence of the disease. Here, Castro-Córdova et al. show that the spores gain entry into the intestinal mucosa via pathways dependent on host fibronectin and ...

Pathogenicity and virulence of Clostridium botulinum

Virulence, 2023
Clostridium botulinum, a polyphyletic Gram-positive taxon of bacteria, is classified purely by their ability to produce botulinum neurotoxin (BoNT). BoNT is the primary virulence factor and the causative agent of botulism.
