Desonide (Prednacinolone) is a synthetic topical glucocorticoid that exerts anti-inflammatory effects by activating glucocorticoid receptors. This activation modulates gene transcription, leading to the production of proteins like lipocortin-1 that inhibit key inflammatory pathways. It is widely used in research models, both in vitro and in vivo, to study steroid-mediated inflammation and immune responses.
