RA + Steroid Drugs Flashcards
Corticosteroid
Types + Effects (not examples)
Glucocorticoid = Cortisol
- +Gluconeogenesis
- +Glycogen phosphorylase (allowing adrenaline +glycogenolysis)
- -IL2 receptor -Th2 responce (⇒Th1 dominance, and less AB production)
Mineralocorticoid = Aldosterone
- Na/K pump (DT+CD)
- Epithelial Na channel (ENaCs)
