More Info:

Biological target: Dexamethasone reduces levels of activated NF-κB in immature dendritic cells (DCs) and inhibits differentiation into mature DCs. It also induces differentiation of human mesenchymal stem cells (MSCs) and is used in the generation of liver organoids. Dexamethasone induces autophagy in acute lymphoblastic leukemia (ALL) cell lines. Dexamethasone acts as viral transduction enhancer by promoting intracellular shuttling of HIV-1 pre-integration complex to the nucleus.
In vitro activity: This study suggests that the anti-inflammatory properties of glucocorticoids relate to their ability to transrepress rather than transactivate genes. Dexamethasone inhibited GM-CSF release from A549 cells with an EC50 value of 2.2 x 10(-9) M). Dexamethasone’s (EC50 = 3.6 x 10(-8) M) ability to induce transcription of the beta2-receptor was correlated with GR DNA binding. Dexamethasone’s (IC50=0.5 x 10(-9) M) ability to inhibit a 3 x kappaB was associated with inhibition of GM-CSF release. Reference: Br J Pharmacol. 1999 Jun;127(4):1003-11. https://pubmed.ncbi.nlm.nih.gov/10433509/
In vivo activity: The administration of low doses of dexamethasone represents a promising adjuvant treatment for pulmonary tuberculosis (TB). In a mice model of progressing TB, dexamethasone administered with conventional antibiotics in late disease stage decreased the lung bacilli load and lung pneumonia, and increased mouse survival. Dexamethasone also decreased the inflammatory response in the SNC and, therefore, sickness behavior and neurological abnormalities in the infected animals.
