We demonstrate here for the first time that the novel, potent peroxisome proliferator-activated receptor (PPAR)-gamma antagonist GW9662 (2-chloro-5-nitrobenzanilide) augments the degree of liver injury associated with haemorrhagic (haemorrhage for 90 min and resuscitation for 4 h), but not endotoxic (6 mg/kg E. coli endotoxin i.v. for 6 h) shock in the anaesthetised rat. Thus, endogenous ligands for PPAR-gamma are released in haemorrhagic, but not endotoxic, shock in sufficient amounts to protect against injury.

Delayed wound healing is a complication of diabetes mellitus and can lead to infection, sepsis, and amputation. Despite the currently available treatments, the global burden of diabetes-related wounds is growing; thus, more effective therapy for diabetic wounds is urgently needed. Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor, is a 28-amino acid peptide hormone.

To effectively mitigate global eutrophication in lakes, regulating sedimentary phosphorus release remains a primary strategy. Enhancing the adsorption and stabilization performance of passivating agents is integral to addressing endogenous phosphorus pollution in aquatic systems. This study presents a novel aerogel with a high specific surface area (663.

Background: The binding of endothelin-1 (ET-1) to endothelin type A receptor (ETAR) performs a critical action in pulmonary arterial smooth muscle cell (PASMC) proliferation leading to pulmonary vascular structural remodeling. More evidence showed that cystathionine γ-lyase (CSE)-catalyzed endogenous hydrogen sulfide (HS) was involved in the pathogenesis of cardiovascular diseases. In this study, we aimed to explore the effect of endogenous HS/CSE pathway on the ET-1/ETAR binding and its underlying mechanisms in the cellular and animal models of PASMC proliferation.

Ghrelin, the endogenous ligand of the growth hormone secretagogue receptor (GHSR), promotes food intake, other feeding behaviours and stimulates growth hormone (GH) release from the pituitary. Growth hormone secretagogues (GHS), such as GHRP-6 and MK-0677, are synthetic GHSR ligands that activate orexigenic Neuropeptide Y neurons that co-express Agouti-Related Peptide (AgRP) in the arcuate nucleus of the hypothalamus when administered systemically. Systemic GHRP-6 also stimulates GH release in humans and rats.

In the last two decades, the endocannabinoid system has emerged as a crucial modulator of motivation and emotional processing. Due to its widespread neuroanatomical distribution and characteristic retrograde signaling nature, cannabinoid type I receptors and their endogenous ligands finely orchestrate somatic and axon terminal activity of dopamine neurons. Owing to these unique features, this signaling system is a promising pharmacological target to ameliorate dopamine-mediated drug-seeking behaviors while circumventing the adverse side effects of, for instance, dopaminergic antagonists.
