Drug-induced phospholipidosis (DIPL) is a metabolic disorder characterized by an excessive intracellular accumulation of phospholipids caused by cationic drugs. Hepatic cells derived from human skin are evaluated as an in vitro model to investigate DIPL and its mechanisms. Human skin stem cells

Adverse outcome pathway (AOP) networks are versatile tools in toxicology and risk assessment that capture and visualize mechanisms driving toxicity originating from various data sources. They share a common structure consisting of a set of molecular initiating events and key events, connected by key

Drug-induced intrahepatic cholestasis (DIC) is a main type of hepatic toxicity that is challenging to predict in early drug development stages. Preclinical animal studies often fail to detect DIC in humans. In vitro toxicogenomics assays using human liver cells have become a practical approach to

Alkaptonuria (AKU) is a rare inborn error of metabolism caused by a defective homogentisate 1,2-dioxygenase (HGD), an enzyme involved in the tyrosine degradation pathway. Loss of HGD function leads to the accumulation of homogentisic acid (HGA) in connective body tissues in a process called

Endotoxins are lipopolysaccharides anchored at the outer membrane of gram-negative bacteria. These pyrogenic compounds can be introduced in pharmaceutical products during their manufacture and could induce severe physiological reactions in humans. This is why endotoxins are dosed, in order to assure

The purpose of the present development is to use avian MoDCs to implement a cellular platform to increase understanding of the immune responses induced by various antigens of interest (e.g. vaccine candidates) and evaluate their immunogenic potential. Considering the difficulty to work on dendritic

Cultivated liver cells are fixed with 4% (w/v) paraformaldehyde (PFA) for 10 minutes at room temperature and subsequently incubated for 15 minutes with 100 mM glycin solution, used to saturate reactive groups generated after PFA fixation. These cells are subsequently incubated for 10 minutes with 1%

For the risk assessment of compounds migrating from food contact materials (FCM), information on the exposure to the migrant as well as its possible hazards is needed. To support the evaluation of both starting products and NIAS from plastic FCM, the VERMEER FCM tool has been developed within the

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells and has been described in detail in OECD TG 487. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that

E. coli is one of the organisms of choice for the production of recombinant proteins. DH5 alpha cells are commonly used for maintenance, propagation and mutation, whilst BL21(DE3) and C43(DE3) are mainly used for expression of the transgene. The advantage of C43(DE3) is that is used to produce
