Background/aim Sepsis is an unregulated systemic response to microbial invasion that can lead to multiple organ failure. This study aims at investigating the relationships among myeloperoxidase (MPO) and CD177 in major organ systems including whole blood, liver, and lung tissues in septic rats. Materials and methods Sepsis was induced by cecal ligation and puncture (CLP) in female Wistar rats. Whole blood, liver, and lung samples were obtained from rats of 3 groups (n = 10 for each group… 
Comparison between MPO, CD177 and NF-κB Gene Expression of Septic Rats Treated with Mentha longifolia Essential Oils
TLDR
The results demonstrated that M. longifolia essential oil treatment could protect against sepsis-induced liver and lung injury by reducing inflammatory factor.
Comparative Effect of Three Non-Steroidal Anti-Inflammatory Drugs on Gene Expression of Myeloperoxidasein Lung and Liver Tissues of Septic Rats
TLDR
It seems that the treatment of animals with selected drugs have the inhibiting effect on the increase of MPO gene expression and results in reducing the damage to the liver and lung tissue caused by sepsis.
Endogenous Sulfur Dioxide Improves the Survival Rate of Sepsis by Improving the Oxidative Stress Response during Lung Injury
TLDR
Endogenous sulfur dioxide improves the survival rate of sepsis by improving the oxidative stress response during lung injury and decreasing the number of WBCS and the percentage of PMN cells.
Transcriptome Meta-Analysis Deciphers a Dysregulation in Immune Response-Associated Gene Signatures during Sepsis
TLDR
The role of significant and widespread immune activation (IL1R2, MMP9), along with oxidative stress (ARG1) and the recruitment of neutrophils, in sepsis (ELANE, MPO) is demonstrated.
Biomarkers of sepsis: time for a reappraisal
TLDR
The number of biomarkers being identified is still increasing although at a slower rate than in the past, and the clinical role of these biomarkers needs to be better evaluated.
Fermented soybean meal extract improves oxidative stress factors in the lung of inflammation/infection animal model
TLDR
It is demonstrated that a diet containing fermented soybean meal extract improved extreme inflammatory response in an infectious disease like sepsis by reducing inflammatory factors.
Identification of a Four-Gene Signature for Diagnosing Paediatric Sepsis
TLDR
A four-gene signature composed of ANXA3, CD177, GRAMD1C, and TIGD3 effectively distinguished patients with paediatric sepsis from those in the control group and can be used as new biomarkers to distinguish patients with parenthesis from healthy individuals.
Neutrophil Phenotypes and Functions in Trauma and Trauma-Related Sepsis.
TLDR
Neutrophils and their functions are highlighted as potential future targets for optimizing post-traumatic treatment strategies, which potentially may improve patient outcomes.

Increased myeloperoxidase enzyme activity in plasma is an indicator of inflammation and onset of sepsis.
Association between the neutrophil myeloperoxidase index and subsets of bacterial infections
TLDR
MPXI appears to be an independent and useful biomarker for the diagnosis and follow-up of infectious diseases, especially when the MPXI values are obtained at regular intervals during the disease courses of the patients.
Interaction of CD44 and hyaluronan is the dominant mechanism for neutrophil sequestration in inflamed liver sinusoids
TLDR
CD44 was revealed as a potential therapeutic target in systemic inflammatory responses involving the liver by a dramatic induction of serum-derived HA-associated protein in sinusoids in response to lipopolysaccharide (LPS).
Caecal ligation and puncture in the rat mimics the pathophysiological changes in human sepsis and causes multi-organ dysfunction
TLDR
CLP in the rat mimics the cardinal clinical features of human sepsis and the subsequent development of multi-organ dysfunction and appears to be the best available animal model currently available, in which to investigate the underlying pathophysiology of sepsi and identify therapeutic targets.
Neutrophil CD177 (NB1 gp, HNA‐2a) expression is increased in severe bacterial infections and polycythaemia vera
TLDR
Only G‐CSF‐stimulated individuals and patients with severe bacterial infections and polycythaemia showed a significantly (P’< 0·001) increased CD177 expression compared with healthy individuals, indicating that neutrophilCD177 expression can increase significantly in certain clinical conditions.
Differential Expression of Granulopoiesis Related Genes in Neutrophil Subsets Distinguished by Membrane Expression of CD177
TLDR
The neutrophil population can be distinguished by membrane expression of CD177 into subsets that are different in expression of GP mRNA but not in GP protein production, and most of these genes were granule protein (GP) coding genes.
Measurement of cutaneous inflammation: estimation of neutrophil content with an enzyme marker.
TLDR
It is demonstrated that MPO can be used as a marker for skin neutrophil content: it is recoverable from skin in soluble form, and is directly related to neutrophIL number.
Characterization of a novel mouse model with genetic deletion of CD177
TLDR
A novel genetic mouse model is established and it is found that CD177 plays an important role in neutrophils, which reduced neutrophil counts in inflammatory skin caused by S. aureus and led to significant cell death.
Novel therapeutic targets for sepsis: regulation of exaggerated inflammatory responses.
TLDR
New promising mechanisms and concepts that could have a key role in anti-inflammatory strategies against sepsis are focused on, including "inflammasome", a multiprotein complex that activates caspase-1 and "the cholinergic anti- inflammatory pathway".

TLDR
The role of NETs in the liver and gastrointestinal system is focused on, outlining their protective and pathological effects and the potential importance of NET-related molecules, including cell-free DNA and hypercitrullinated histones, as biomarkers and targets for therapeutic intervention in gastrointestinal diseases is described.
