Conformational activation and inhibition of von Willebrand factor by targeting its autoinhibitory module.

Activation of von Willebrand factor (VWF) is a tightly controlled process governed primarily by local elements around its A1 domain. Recent studies suggest that the O-glycosylated sequences flanking the A1 domain constitute a discontinuous and force-sensitive autoinhibitory module (AIM), although its extent and conformation remains controversial. Here, we used a targeted screening strategy to identify 2 groups of nanobodies.

Design, Synthesis, and Evaluation of New 1-Benzo[]imidazole Based PqsR Inhibitors as Adjuvant Therapy for Infections.

is one of the top priority pathogens that requires immediate attention according to the World Health Organisation (WHO). Due to the alarming shortage of novel antimicrobials, targeting quorum sensing (QS), a bacterial cell to cell signaling system controlling virulence, has emerged as a promising approach as an antibiotic adjuvant therapy. Interference with the system, one of three QS systems in , results in reduction of bacterial virulence gene expression and biofilm maturation.

Inherited ADAMTS13 mutations associated with Thrombotic Thrombocytopenic Purpura: a short review and update.

ADAMTS13 is a plasma metalloprotease with the primary function of cleaving VWF to maintain hemostasis. Circulating ADAMTS13 is in the closed conformation until blood vessel injury triggers a VWF-dependant activation to the open active form of the protein. ADAMTS13 is a multi-domain protein with the domains broadly functioning to interact and cleave VWF or maintain global latency of ADAMTS13.
