Abstract Circulating tumor cells (CTCs) are pivotal biomarkers in metastasis, however, the underlying molecular mechanism of CTCs behavioral heterogeneity during metastasis remains unexplored. Here, an integrative workflow is developed to link behavior characteristics metabolic profiling within individual CTCs, which simulates metastatic process on a microfluidic system and combined with single‐cell mass spectrometry (MS) detection. Spheroid‐derived HCT116 tracked extracted via temporary vascular system, revealing various arrest patterns under biomimetic shear flow. Downstream MS analysis characterizes 17 cellular metabolites associates profiles de‐adhesion behaviors same identifying potential high‐metastatic subpopulation enhanced ability evaluating critical involved pathways. Additionally, metastasis‐inhibiting effect anti‐tumor drug 5‐fluorouracil by reducing spheroids elucidated.

Introduction Metabolism plays a complex role in the evolution of cancerous tumors, including inducing multifaceted effect on immune system to aid escape. Immune escape is, by definition, collective phenomenon requiring presence two cell types interacting close proximity: tumor and immune. The microenvironmental context these interactions is influenced dynamic process blood vessel growth remodelling, creating heterogeneous patches well-vascularized or acidic niches. Methods Here, we present multiscale mathematical model that captures phenotypic, vascular, microenvironmental, spatial heterogeneity which shapes acid-mediated invasion over biologically-realistic time scale. explores several mechanisms such as i) acid inactivation cells, ii) competition for glucose, iii) inhibitory checkpoint receptor expression (PD-L1). We also explore efficacy anti-PD-L1 sodium bicarbonate buffer agents treatment. To understanding cellular phenomenon, define six phenotypes (termed “meta-phenotypes”): Self-Acidify, Mooch Acid, PD-L1 Attack, PD-L1, Proliferate Fast, Starve Glucose. Results Fomenting stronger response leads initial benefits (additional cytotoxicity), but this advantage offset increased turnover accelerated emergence aggressive phenotypes. This creates bimodal therapy landscape: either should be maximized complete cure, kept check avoid rapid invasive cells. These constraints are dependent vascular context, acidification, strength response. Discussion helps untangle key evolutionary costs three phenotypic axes treatment: acid-resistance, glycolysis, expression. concomitant treatments promising treatment strategy limit adverse effects

T cell receptor (TCR) binding to cognate antigen on the plasma membrane of an antigen-presenting (APC) triggers immune synapse (IS) formation. The IS constitutes a dedicated contact region between different cells that comprises signaling platform where several cues evoked by TCR and accessory molecules are integrated, ultimately leading effective signal transmission guarantees intercellular message communication. This eventually leads lymphocyte activation efficient execution effector tasks, including cytotoxicity subsequent target death. Recent evidence demonstrates information forming synapses is produced, significant extent, generation secretion distinct extracellular vesicles (EV) from both APC.
