Molecular Control of Immune/Inflammatory Responses: Interactions Between Nuclear Factor-κB and Steroid Receptor-Signaling Pathways

I. Introduction II. Nuclear Factor-κB (NF-κB) A. Introduction B. NF-κB is a dimeric transcription factor C. The regulatory subunit IκB is an inhibitor of NF-κB D. Activation and function of NF-κB E. The transcription factor NF-κB interacts with multiple transcription factors and transcriptional co-factors F. Transgenic animals suggest a complex role for NF-κB family members in immunity and development III. Steroid Hormones/Receptors: Glucocorticoids and the Glucocorticoid Receptor (GR) A. General background B. Glucocorticoid mechanism of action: the GR C. Glucocorticoid physiology D. GR/NF-κB interactions E. GR interacts with other transcription factors and transcriptional cofactors IV. NF-κB and GR Antagonism: Physiological Significance? V. Interactions Between NF-κB and Other Steroid Hormone Receptors A. Androgen receptor (AR) B. Estrogen receptor (ER) C. Progesterone receptor (PR) VI. Summary/Conclusions
