R. Hooghe et al., GROWTH-HORMONE AND PROLACTIN ARE PARACRINE GROWTH AND DIFFERENTIATIONFACTORS IN THE HEMATOPOIETIC SYSTEM, Immunology today, 14(5), 1993, pp. 212-214
The pituitary secretory proteins growth hormone (GH) and prolactin (PR
L) do not, as yet, have major roles in haematology or immunology. Rece
nt evidence indicates that these hormones are haemopoietic growth fact
ors and exert immunomodulatory functions at physiological concentratio
ns. Here Robert Hooghe and colleagues discuss the significance of thes
e hormones on different aspects of the immune system.
