Development of an ectopic huLiver model for Plasmodium liver stage infection.

Early Plasmodium falciparum and P. vivax infection requires parasite replication within host hepatocytes, referred to as liver stage (LS). However, limited understanding of infection dynamics in human LS exists due to species-specificity challenges.

A radiological score for the assessment of tuberculosis progression: Validation in mouse models.

The sensitivity of in vivo low-dose high-resolution micro-computed tomography imaging enables monitoring the lung damage caused by tuberculosis. Here, we propose a radiological score integrated in the experimental workflow that enables longitudinal monitoring for prospective efficacy studies in drug development programs. The score is based on an automatic measurement of total unaffected lung volume in vivo normalized for inter-subject comparison.

X-ray-based virtual slicing of TB-infected lungs.

Hollow organs such as the lungs pose a considerable challenge for post-mortem imaging in preclinical research owing to their extremely low contrast and high structural complexity. The aim of our study was to enhance the contrast of tuberculosis lesions for their stratification by 3D x-ray-based virtual slicing. Organ samples were taken from five control and five tuberculosis-infected mice.

Benzofuran-substituted urea derivatives as novel P2Y(1) receptor antagonists.

Benzofuran-substituted urea analogs have been identified as novel P2Y(1) receptor antagonists. Structure-activity relationship studies around the urea and the benzofuran moieties resulted in compounds having improved potency. Several analogs were shown to inhibit ADP-mediated platelet activation.

A murine model of falciparum-malaria by in vivo selection of competent strains in non-myelodepleted mice engrafted with human erythrocytes.

To counter the global threat caused by Plasmodium falciparum malaria, new drugs and vaccines are urgently needed. However, there are no practical animal models because P. falciparum infects human erythrocytes almost exclusively.
