The authors demonstrated that the primary-tumor-derived cells PANC1/BxPC3 activated the innate immune anti-tumoral responses, while the metastatic cells AsPC1/CFPAC1 suppressed the innate immune system. Dougnon et al. [[19]] illustrate in their review the possibility of using zebrafish as a model to study two neurodevelopmental disorders, i.e., autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). Wang et al. [[14]] explored the effectiveness of different drugs against PDAC cells as well as the interaction of tumor cells with the immune system. Notably, PANC1 and BxPC3 recruited more innate immune cells (coro1a:GFP) to the tumor micro-environment compared to the AsPC1 cells, and recruitment increased over time. [Extracted from the article]
