BACKGROUND Cholinesterase inhibitors (Ch-I) improve survival in experimental sepsis consistent with activation of the cholinergic-anti-inflammatory-pathway. So far, less is known about whether Ch-I have a direct immunomodulatory effect on immune cells (polymorphonuclear neutrophils, PMN) in the

Pretreatment of rats with atropine and the reversible esterase inhibitor physostigmine [-)PHY), prior to injection of a lethal dose of the irreversible organophosphate sarin (0.13 mg/kg), protects 100% of the animals from lethality. We have used quantitative light and qualitative electron microscopy

The natural alkaloid (-)PHY is a reversible anticholinesterase carbamate, but in contrast, its optical isomer (+)PHY, is a very weak anticholinesterase. We have shown that treatment of rats with atropine and (-)PHY prior to injections of a lethal dose of the irreversible organophosphate sarin (0.13

OBJECTIVE To observe the effect of acetylcholine (ACh) on lipopolysaccharide (LPS) induced inflammatory model of rat alveolar macrophages, and to observe the effect of the acetylcholinesterase inhibitor physostigmine (Phy) on the anti-inflammatory effect of ACh. METHODS The rat alveolar macrophages

OBJECTIVE Donepezil, a reversible acetylcholinesterase inhibitor, improves cognitive function of Alzheimer's disease. Stimulation of cholinergic system was reported to improve long-term survival of rats with chronic heart failure and to attenuate inflammatory response in mice with

Gulf War Illness (GWI) is a chronic multi-symptom disorder affecting veterans of the 1991 Gulf War. Among the symptoms of GWI are those associated with sickness behavior, observations suggestive of underlying neuroinflammation. We have shown that exposure of mice to the stress hormone,

OBJECTIVE Lethal sepsis occurs when an excessive inflammatory response evolves that cannot be controlled by physiologic anti-inflammatory mechanisms, such as the recently described cholinergic anti-inflammatory pathway. Here we studied whether the cholinergic anti-inflammatory pathway can be
