Summary

Prolactin, a hormone produced by immune cells, influences immune responses and is implicated in rheumatic diseases. Lowering prolactin levels may improve treatments for autoimmune conditions.

Area of Science:

  • Immunology
  • Endocrinology
  • Rheumatology

Background:

  • Immune cells synthesize prolactin and possess receptors for it.
  • Several cytokines and neuropeptides modulate prolactin release.
  • Prolactin plays a role in immune function and pathogenesis of certain inflammatory conditions.

Purpose of the Study:

  • To review the role of prolactin in immune system regulation.
  • To explore the involvement of prolactin in rheumatic and autoimmune diseases.
  • To evaluate the therapeutic potential of modulating prolactin levels.

Main Methods:

  • Literature review of studies on prolactin in immunity and disease.
  • Analysis of in vitro and in vivo experimental data.
  • Examination of clinical findings in patients with rheumatic and autoimmune conditions.

Main Results:

  • Prolactin affects lymphocyte proliferation, differentiation, and function.
  • Hyperprolactinemia is observed in systemic lupus erythematosus, fibromyalgia, rheumatoid arthritis, and uveitis.
  • Bromocriptine treatment shows promise in managing certain autoimmune conditions and may enhance immunosuppressive therapy.

Conclusions:

  • Prolactin is an important factor in immune regulation with implications for rheumatic diseases.
  • Modulating prolactin levels, potentially with bromocriptine, could offer new therapeutic strategies.
  • Further research is needed to fully elucidate prolactin's role in autoimmune diseases.
