[Pseudotuberculosis - a case report of gastroenteritis in a five-year-old boy].

The article describes a case of a rare infection caused by Yersinia pseudotuberculosis in a five-year-old boy admitted to the hospital. The infection was manifested by the so-called right lower quadrant syndrome, or terminal ileitis. The Y.

KLK5 and KLK7 Ablation Fully Rescues Lethality of Netherton Syndrome-Like Phenotype.

Netherton syndrome (NS) is a severe skin disease caused by the loss of protease inhibitor LEKTI, which leads to the dysregulation of epidermal proteases and severe skin-barrier defects. KLK5 was proposed as a major protease in NS pathology, however its inactivation is not sufficient to rescue the lethal phenotype of LEKTI-deficient mice. In this study, we further elucidated the in vivo roles of the epidermal proteases in NS using a set of mouse models individually or simultaneously deficient for KLK5 and KLK7 on the genetic background of a novel NS-mouse model.

A viable mouse model for Netherton syndrome based on mosaic inactivation of the Spink5 gene.

Netherton syndrome (NS) is caused by mutations in the SPINK5 gene. Several Spink5-deficient mouse models were generated to understand the mechanisms of NS in vivo. However, Spink5-deficiency in mice is associated with postnatal lethality that hampers further analysis.
