Dynamics of TNFalpha signaling and drug-related toxicity
In previous studies at our laboratory it was demonstrated that drug exposure of HepG2 cells can lead to an altered TNFα-induced NF-κB oscillatory phenotype, concurrent with a synergistically increased sensitivity for TNFα-induced apoptosis.

stress pathways for mechanistic understanding of chemical-induced liver injury
Cellular stress response pathways are activated upon exposure to chemicals and help organisms deal with various molecular dangers (e.g. oxidative stress). When these pathways become hyper-activated an adverse response takes place and cells die, which may lead to organism-level toxicity such as drug-induced…

Rights of the Relational Self: Law, Culture, and Injury in the Global North and South
Although official law generally conceives of personal injury victims as individual rights holders, the actual experience of physical injury and its consequences is relational. Indeed, many researchers in the global North as well as the global South have contended that the very concept of the Self should…

Ovalbumin coated pH-sensitive microneedle arrays effectively induce ovalbumin-specific antibody and T-cell responses in mice
The aim of this work was to study the applicability of antigen-coated pH-sensitive microneedle arrays for effective vaccination strategies. Therefore, a model antigen (ovalbumin) was coated onto pH-sensitive (pyridine-modified) microneedle arrays to test pH-triggered antigen release by applying the…
