Our studies also revealed that obesogenic diet feeding induces alternation of hematopoiesis with dramatic increase of pro-inflammatory neutrophil production and pro-inflammatory phenotype in mice. Interestingly, mice lacking of neutrophil-specific protease neutrophil elastase are resistant not only to diet-induced neutrophil production but also obesogenic diet-induced vascular damage, adipose inflammation and fibrosis, nonalcoholic steatohepatitis (NASH), and insulin resistance. We are in the process to study how nutritional factors are involved in the regulation of neutrophil differentiation and how this process is related to the development of systemic inflammation, NASH, adipose tissue fibrotic remodeling, and metabolic disorders.<\/span><span data-ccp-props=\"{&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559738&quot;:120}\"><\/span><\/li>\n<\/ol>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:1,&quot;335551550&quot;:6,&quot;335551620&quot;:6,&quot;335559740&quot;:120}\">\u00a0<\/span><\/p>\n<ol start=\"2\">\n<li><b><i><span data-contrast=\"none\"> Neutrophils play pivotal role in obesity-related vascular injury and vascular aging.<\/span><\/i><\/b> <br style=\"clear: both;\" \/><span data-contrast=\"none\">Our study revealed that neutrophils contribute to obesity-related vascular leakage and immune cell infiltration in adipose tissue by releasing neutrophil elastase. The latter increases vascular permeability and leukocyte extravasation through activating protease activated receptor 2 (PAR2) and Rho kinase signaling in vascular endothelial cells. Our recent studies also revealed that neutrophils are involved in vascular aging and related arterial stiffness<\/span><span data-contrast=\"auto\">.
