粒细胞集落刺激因子的研究新进展

粒细胞集落刺激因子（granulocyte colony—stimulating factor，G—CSF）是由单核细胞、成纤维细胞和内皮细胞产生的一种造血生长因子，能与细胞表面的特定受体结合，促使中性粒细胞系造血祖细胞生长和分化，保护中性粒细胞避免凋亡并加强它们的功能。G—CSF被广泛地用于由各种原因引起的粒细胞减少症并取得了较好的疗效。本文对G—CSF的结构和动员机制、研发现状、作用特点、药代动力学、临床应用与副反应及应用前景等问题作一综述。

Recent Advances in Research on Granulocyte Colony-Stimulating Factor——Review

Granulocyte colony-stimulating factor (G-CSF) is a kind of hematopoietic growth factor which is produced by monocytes, fibroblasts and endothelial cells. G-CSF acts on neutrophilic progenitor cells by binding to specific cell surface receptors, thereby stimulates proliferation, differentiation, commitment, and selected end-cell functional activation including enhanced phagocytic ability, priming of the cellular metabolism associated with respiratory burst, antibody dependent killing and the increased expression of some functions associated with cell surface antigens. G-CSF is effective and safe for treatment of neutropenia. In this paper, structure of G-CSF and its mechanism, recent status of research on G-CSF, pharmacokinetics, clinical application, adverse effects and prospect of G-CSF are mainly reviewed.
