Annexin A1 (AnxA1), a Ca2+ and phospholipid binding protein, is a mediator of glucocorticoid (GC) action in the neuroendocrine and host defence systems. It acts at least in part via members of the membrane bound formyl peptide receptor (Fpr) family, particularly Fpr2 which is also a target for the anti-inflammatory eicosanoid, lipoxin A4, as well as pro-inflammatory bacterial formylated peptides. Unregulated inflammation underlies many diseases, including...

Sepsis is a major clinical problem, caused by a hyperactive immune response following infection. Worldwide prevalence is estimated at 1.8 m/year and mortality at around 40%1. Protective effects of the endogenous anti-inflammatory protein annexin A1 have previously been shown in many models, including sepsis2. We therefore chose to investigate the role of the annexin A1 peptide mimetic, Ac2–26, in murine experimental endotoxaemia, and to ascertain whe...

Sepsis continues to be a leading clinical problem, with ~1.8 million people worldwide affected. This continual increase in sepsis and related deaths is in part due to age, increased frequency of invasive procedures and widespread bacterial antibiotic resistance, with mortality often related to underlying disorders that often accompany sepsis. Sepsis affects the brain, and the impairment of brain function is often associated with severe infectious disease1. The endog...

Sexual dimorphisms have been observed in numerous diseases, particularly those associated with inflammation. Generally, males are more at risk of developing infection and subsequent mortality1, whilst women are more prone to develop autoimmune disorders2. Hormones, particularly oestrogens, are thought to play a significant role effecting these dimorphisms, and oestrogens have been shown to reduce the severity of sepsis3.I...

The anti-inflammatory protein, annexin 1 (ANXA1) acts via a formyl peptide receptor (FPR), possibly FPR2, in the neuroendocrine system to mediate feedback effects of glucocorticoids and thereby modulate the HPA responses to immune insults. Here, we explored further the role of ANXA1 and the FPR family in mediating the HPA responses to endotoxin (LPS), focusing on the adrenal cortex.Adult male mice treated with LPS (500 μg/kg, i.p.) showed time-depen...
