WebInterleukin-1 (IL-1) family cytokines are key signaling molecules in both the innate and adaptive immune systems, mediating inflammation in response to a wide range of stimuli. The basic mechanism of signal initiation is a stepwise process in which an agonist cytokine binds its cognate receptor. Together, this cytokine-receptor complex recruits an often … WebApr 12, 2024 · To infer the cell state–specific communications, we first identified differentially expressed signaling genes across all cell groups within sample objects, using the Wilcoxon rank sum test with the significance level of 0.05. After nominating clusters as cell types, the CellChat object was created by “createCellChat.” ...
