General description
Pentraxin 3 (PTX3) or tumor necrosis factor (TNF)-stimulated gene is the prototypic member of the long pentraxin family sharing the C-terminal domain with short pentraxins and containing a unique N-terminal domain. The gene encoding this protein is localized on human chromosome 3q25.32 and consists of 3 exons. Recombinant human Pentraxin 3 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography.
Biochem/physiol Actions
Pentraxin 3 (PTX3) is an acute phase protein produced and released at inflammatory sites by diverse cell types including monocytes/macrophages, endothelial cells, vascular smooth muscle cells, fibroblasts, and adipocytes. It plays a role in the regulation of innate resistance to pathogens, inflammatory reactions, possibly clearance of self-components and female fertility. PTX3 particularly functions as a soluble pathogen recognition receptor and confers resistance against pathogens. Studies indicate that the protein removes apoptotic cells during immune responses. It associates with complement factor H, which is a complement regulator protein.

Pentraxin 3 (PTX3), a modulator of tumor-associated inflammation, is known to be positively correlated with tumor grade and severity of malignancies, but its exact role remains unclear. This study found that PTX3 expression was up-regulated in distant bone metastases of

The long pentraxin 3 (PTX3) is a soluble recognition molecule with multiple functions including innate immune defense against certain microbes and the clearance of apoptotic cells. PTX3 interacts with recognition molecules of the classical and lectin complement pathways and thus

The long pentraxin-3 (PTX3) is a key component of the humoral arm of the innate immune system. PTX3 is produced locally in response to pro-inflammatory stimuli. To investigate PTX3 levels and its use as a biomarker in patients with systemic
