The regulation of TNF-α and IL-6 secretion in LPS-stimulated Peritubular cells was investigated in vitro. Immature rat Peritubular cells were incubated with LPS (10 μg/ml) over 24 h culture. TNF-α and IL-6 were measured in the culture medium by ELISA at 24 h, TNF-α and IL-6 genes by real-time RT-PCR, and activation of NF-κB, MAPKs, and AP-1 signal transduction pathways by western blotting. LPS stimulated the mRNA expression of IL-6 and much more the ex...

MIF can override the anti-inflammatory actions of glucocorticoids during immune response, and thus is an important pro-inflammatory factor. The presence of MIF in the cytoplasm of adenomatous cells of the anterior pituitary has been described, and high levels of MIF in other rapidly-proliferating tissues have been demonstrated. It is hypothesized that MIF release from these cells is influenced by the hypothalamo-pituitary-adrenal axis, and that ACTH and MIF are released simult...
