Pituitary gland: neuropeptides, neurotransmitters and growth factors.
The hypothalamus receives neuronal afferents from numerous sources including inputs from limbic structures, such as the amygdala and hippocampus, and from brainstem regions involved in the regulation of the cardiovascular system and other autonomic functions. These afferents using a vast array of neurotransmitters and neuropeptides influence the activity of the hypothalamic neurons which synthe...
متن کاملExtracellular growth factors and mitogens cooperate to drive mitochondrial biogenesis.
Cells generate new organelles when stimulated by extracellular factors to grow and divide; however, little is known about how growth and mitogenic signalling pathways regulate organelle biogenesis. Using mitochondria as a model organelle, we have investigated this problem in primary Schwann cells, for which distinct factors act solely as mitogens (neuregulin) or as promoters of cell growth (ins...
متن کاملPlatelet-derived Growth Factors and Fibroblast Growth Factors Are Mitogens for Rat Schwalm Cells
Rat sciatic nerve Schwann cells in culture respond to a limited range of mitogens, including glial growth factor, transforming growth factors beta-1 and beta-2 (TGF-fll, TGF-/~2), some cell membrane-associated factors, and to agents such as cholera toxin and forskolin which raise intracellular levels of cAME These responses require the presence of FCS, which exhibits little or no mitogenic acti...

متن کاملResponse patterns of hairy cell leukemia to B-cell mitogens and growth factors.
The effect of mitogens and/or recombinant B-cell growth factors (M/GFs) on the in vitro growth of hairy cells was examined. Tumor cells were isolated from the spleens of four patients with hairy cell leukemia (HCL) by Ficoll-Hypaque sedimentation and E-rosetting. Enrichment for tumor cells was confirmed with intracytoplasmic immunoglobulin (Ig) staining, tartrate resistant acid phosphatase (TRA...
