Resistance Development: A Major Piece in the Jigsaw Puzzle of Tumor Size Modeling.

ABSTRACT: Mathematical models of tumor size (TS) dynamics and tumor growth inhibition (TGI) need to place more emphasis on resistance development, given its relevant implications for clinical outcomes. A deeper understanding of the underlying processes, and effective data integration at different complexity levels, can foster the incorporation of new mechanistic aspects into modeling approaches, improving anticancer drug effect prediction. As such, we propose a general framework for developing future semi-mechanistic TS/TGI models of drug resistance.

Project description:Due to the aging of the population and despite the enormous scientific effort, Alzheimer's disease remains one of the biggest medical and pharmaceutical challenges in current medicine. Novel insights highlight the importance of neuroinflammation as an undeniable player in the onset and progression of Alzheimer's disease. Tumor necrosis factor is a master inflammatory cytokine that signals via tumor necrosis factor receptor 1 and tumor necrosis factor receptor 2, but that also regulates several brain functions in health and disease. However, clinical trials investigating drugs that interfere with the tumor necrosis factor pathway in Alzheimer's disease led to inconclusive results, partially because not only the pro-inflammatory tumor necrosis factor/tumor necrosis factor receptor 1, but also the beneficial tumor necrosis factor/tumor necrosis factor receptor 2 signaling was antagonized in these trials. We recently found that tumor necrosis factor is the main upregulated cytokine in the choroid plexus of Alzheimer's disease patients, signaling via tumor necrosis factor receptor 1. In agreement with this, choroidal tumor necrosis factor/tumor necrosis factor receptor 1 signaling was also upregulated in different Alzheimer's disease mouse models. Interestingly, both genetic and nanobody-based pharmacological blockage of tumor necrosis factor receptor 1 signaling was accompanied by favorable effects on Alzheimer's disease-associated inflammation, choroidal morphology and cognitive functioning. Here, we briefly summarize the detrimental effects that can be mediated by tumor necrosis factor/tumor necrosis factor receptor 1 signaling in (early) Alzheimer's disease, and the consequences this might have on the disease progression. As the main hypothesis in Alzheimer's disease clinical trials is still based on the amyloid beta-cascade, the importance of Alzheimer's disease-associated neuroinflammation urge the development of novel therapeutic strategies that might be effective in the early stages of Alzheimer's disease and prevent the irreversible neurodegeneration and resulting memory decline.
