Neutrophils are often exclusively considered as a first-line innate immune defence, able to rapidly kill or trap pathogens and causing in case of over-activation tissue damage. In the female reproductive tract, however, the presence and activity of neutrophils seems to be tightly regulated. Major players in orchestrating this regulation are cyclical steroid sex hormones present during the menstrual cycle and pregnancy. This review describes the role of sex hormones in regulating directly or indirectly the functionality of neutrophils, the role of neutrophils during fertilization and pregnancy and in controlling viral, fungal and bacterial infection. This review also discusses the consequence of overt neutrophil activation in pregnancy pathologies.

Regulated sequential exocytosis of neutrophil granules is essential in orchestrating the innate immune response, while uncontrolled secretion causes inflammation. We developed and characterized Nexinhib20, a small-molecule inhibitor that targets azurophilic granule exocytosis in neutrophils by blocking the interaction between the small GTPase Rab27a and its effector JFC1. Its therapeutic potential has been demonstrated in several pre-clinical models of inflammatory disease.

Background: Inflammation is a critical component in the process of resolved hepatitis B virus (HBV) infection. The neutrophil-to-lymphocyte ratio (NLR) serves as a sensitive indicator of systemic inflammation and immune activation. Our study aimed to investigate the correlation between elevated NLR levels and the risk of all-cause mortality in patients with resolved HBV infection.

Sepsis is a life-threatening condition caused by severe infection and often complicates acute respiratory distress syndrome (ARDS) and acute lung injury (ALI) due to the collapse of the oxidative and inflammatory balance induced by microbial pathogens, including lipopolysaccharides (LPS). In sepsis-related ARDS/ALI, NADPH oxidase (NOX) and toll-like receptors (TLR) in neutrophils and macrophages are key players in initiating oxidative and inflammatory imbalances. Although NOX and TLR activation has been linked to carbon monoxide (CO), the mechanism by which CO affects sepsis-related ARDS/ALI through NOX and TLR remains unknown.

Background: Sepsis is an infection-related systemic inflammation with high mortality rates. Activation of formyl peptide receptor 1 (FPR1) in immune cells can promote their chemotaxis and inflammatory response, which imbalances immune response during the process of sepsis. FPR1 blockade did diminish systemic inflammatory response during bacterial infection.

Background: (Lanata) is generally used to treat pustule infection in Inner Mongolia folk medicine and is called "the holy medicine for pustule." However, the pharmacological mechanism of Lanata in treating pustule infection is still unclear.

Aims: This study aimed to investigate the therapeutic effects of Lanata on skin infection and explore the underlying mechanisms.
