丝裂原活化蛋白激酶(MAPK)超家族是介导细胞反应的重要信号系统。研究发现,该超家族亚族p38 MAPK通路在造血细胞调节过程中占据重要地位,抑制p38 MAPK通路可一定程度缓解衰老或者疾病引发的造血细胞功能下降。深入研究p38 MAPK通路在造血系统中的下游作用底物,将对临床造血干细胞的应用以及造血系统疾病发病机制研究提供新的思路。
Mitogen-activated protein kinase(MAPK)superfamily is an important signal mediating many cellular reactions.The subfamily p38 MAPK plays an important role in the regulation of hematopoietic system.Inhibition of p38 MAPK pathway can alleviate the function decline of hematopoietic cells caused by senescence or deseases.To further research the substrates of p38 MAPK pathway in hematopoietic cells will provide new ideas for the clinical application of hematopoietic stem cells and mechanisms of hematopoietic system diseases.
