Neutrophil Extracellular Traps (NETs) Are a Driver of Cancer Progression and Metastasis and Can Also Limit the Effectiveness of Current Cancer Therapies
Understanding the Role of NETs
NETs are weblike structures composed of extracellular chromatin coated with histones and other proteins. NETs are expelled by activated neutrophils, in response to microbial or pro-inflammatory challenges. However, excessive production or reduced clearance of NETs can lead to aggravated inflammatory and autoimmune pathologies, as well as creation of pro-tumorigenic niches in the case of cancer growth and metastasis.
Elevated levels of NETs lead to inflammation and a pro-tumorigenic environment that potentiates coagulopathies and cancer progression.
The Role of NETs in Cancer Progression
Our DNase I Platform Employs an Enzyme Designed to Destroy NETs
DNase I Improves Efficacy of PD-1 Blockade
Systemic administration of DNase I improves the efficacy of PD‐1 blockade to reduce the growth of cancer in MC38 colorectal cancer cell model
Combination of DNase I and anti-PD-1 mAb resulted in the lowest tumor volume growth, superior to either DNase I or anti-PD-1 alone
