Effects of human growth hormone on immune functions: in vitro studies on cells of normal and growth hormone-deficient children.

Published

Journal Article

We have studied the in vitro effects of human growth hormone on cell surface markers and mitogenic responses of peripheral blood lymphocytes (PBL) of normal and growth hormone-deficient children before, during and after treatment with growth hormone. Growth hormone resulted in a decrease in B cell expression but it did not affect expression of T cell subsets. Growth hormone depressed the proliferation of PBL of normal and untreated growth hormone-deficient children. The proliferative responses to phytohemagglutinin (PHA) versus PHA with growth hormone were not statistically different, though the responses of most normal and on treatment children were diminished by the addition of growth hormone. PBL derived from growth hormone-deficient children during treatment with human growth hormone exhibited significantly greater spontaneous proliferation then the PBL of normal children. Growth hormone further significantly enhanced their proliferation. PHA and PHA with growth hormone resulted in significantly greater proliferation of these patients' PBL when compared to those of normal children. We demonstrated that human growth hormone had substantial in vitro effects on immune functions. These effects, some of which depend on the treatment status of the children, may need to be considered in the clinical use of human growth hormone.
