Inflammatory and stress-response transcriptional network

The inflammatory and stress-response transcriptional network is a complex, interconnected system of signaling pathways and transcription factors that coordinate the cellular response to external and internal stressors (Nature Reviews Immunology, 2017). Central to this network are master regulators like NF-κB, AP-1, and the STAT family, which integrate signals from various receptors to drive the expression of genes involved in inflammation, immunity, and cell survival (Cell, 2018). While these responses are vital for acute defense and homeostasis, chronic activation of the network is a hallmark of numerous pathologies, including rheumatoid arthritis, inflammatory bowel disease, and various cancers (Pharmacological Reviews, 2012). Pharmacological intervention typically targets specific nodes or receptors within the network, such as the glucocorticoid receptor or Janus kinases, to suppress pathological gene expression (Nature Reviews Drug Discovery, 2014). However, the extensive crosstalk and redundancy within the network present significant challenges for achieving therapeutic selectivity without compromising essential immune functions (StatPearls, 2023).

Modulation of gene transcription through the activation or inhibition of master transcription factors (e.g., NF-κB, STATs, NRF2) that bind to specific DNA response elements to regulate the expression of inflammatory and stress-related genes (Nature Reviews Drug Discovery, 2014; Pharmacological Reviews, 2012).
