β-Thromboglobulin (β-TG), or beta-thromboglobulin, is a chemokine protein secreted by platelets. [1] [2] It is a type of chemokine (C-X-C motif) ligand 7. [3] Along with platelet factor 4 (PF4), β-TG is one of the best-characterized platelet-specific proteins. [4] β-TG and PF4 are stored in platelet alpha granules and are released during platelet activation. [1] [4] [5] As a result, they are useful markers of platelet activation. [1] [4] β-TG also has multiple biological activities, for instance being involved in maturation of megakaryocytes. [6]

Biological actions

β-TG is a chemoattractant, strongly for fibroblasts and weakly for neutrophils. It is a stimulator of mitogenesis, extracellular matrix synthesis, glucose metabolism, and plasminogen activator synthesis in human fibroblasts. [5]

β-TG also affects megakaryocyte maturation, and thus helps in regulating platelet production. [5]

Clinical uses

Levels of β-TG is used to index platelet activation. It is measured by ELISA in blood plasma or urine, and often in conjunction with PF4. [5]

Influences

β-TG levels may increase with age. [7] It is elevated in diabetes mellitus. [8]

β-TG levels have been found to be increased by treatment with the synthetic estrogen ethinylestradiol, though were not significantly increased by the natural estrogen estradiol valerate. [9] [10] [11] [12] Levels of β-TG have also been found to be increased or unchanged during normal pregnancy. [13]
