Annexin 1 (ANXA1) externalised from folliculostellate cells is known to be an essential intermediate in the early delayed (30 min- 3 h) negative feedback of glucocorticoids on the release of ACTH and other pituitary hormones. We have used a well-characterised folliculostellate cell line (TtT/GF cells) to investigate the mechanism by which ANXA1, a cytoplasmic protein, is externalised by cells. Externalisation is stimulated by dexamethasone (Dex) and inhibited by inhibitors of ...
