This study investigates the effects of varying concentrations of kynurenine and cytokine cocktail on 3H-thymidine incorporation, an indicator of cell proliferation, and the expression of critical adhesion molecules like ICAM and PDL1 in MCEC cells. Supplementary figures illustrate the dose-dependent response of thymidine incorporation with 3H-thymidine assays under different kynurenine concentrations. Additionally, the upregulation of ICAM by ICOSL and the apoptosis rates in response to cytokine exposure are assessed, providing insights into cellular dynamics under inflammatory conditions.
