Effect of LPS and the glucocorticoid dexamethasone on the mouse Bone Marrow Derived Macrophage Proteome

ABSTRACT: The concentrations and copy number of proteins in the mouse Bone Marrow Derived proteome was determined for control, 10 ng/mL LPS stimulation, and LPS stimulation plus the addition of 100 nM dexamethasone, after an incubation for 24 hours and with four biological replicates for each condition. Over 6000 proteins were detected, 410 of which were upregulated by LPS (> 1.5-fold increase, adjusted p value < 0.05). 125 of these LPS-induced proteins were significantly regulated by Dexamethason > 1.5 fold 899 increase or decrease, adjusted p value <0.05).

Frontiers in immunology 20231024

Glucocorticoids potently inhibit expression of many inflammatory mediators, and have been widely used to treat both acute and chronic inflammatory diseases for more than seventy years. However, they can have several unwanted effects, amongst which immunosuppression is one of the most common. Here we used microarrays and proteomic approaches to characterise the effect of dexamethasone (a synthetic glucocorticoid) on the responses of primary mouse macrophages to a potent pro-inflammatory agonist,  ...[more]
