Abstract:
The purpose of this review is to summarize experimental findings showing that Mg modulates cellular events involved in inflammation. Severe experimental Mg deficiency in the rat induces after a few days a clinical inflammatory syndrome characterized by PMN and macrophage activation, release of inflammatory cytokines and acute phase proteins, excessive production of free radicals. Increasing Mg concentration decreases inflammatory response while reduction in the extracellular Mg results in cell activation. Because Mg acts as a natural calcium antagonist, the molecular basis for inflammatory response is probably the result of modulation of intracellular calcium concentration. Mg deficiency contributes to an exaggerated response to immune stress, hyperlipemia, atherosclerosis, endothelial dysfunction, thrombosis, hypertension and free radical damages. Moreover activated endothelium facilitates adhesion and migration of cancer cells. Experimental findings in animal models suggest that inflammation is the missing link to explain the role of Mg in many pathological conditions.
Insights
Magnesium (Mg) deficiency in rats triggers an inflammatory syndrome. Restoring Mg levels reduces inflammation, suggesting Mg
Area of Science:
- Biochemistry
- Cell Biology
- Immunology
Context:
- Magnesium plays a crucial role in cellular functions.
- Inflammation is implicated in numerous pathological conditions.
- Understanding Mg's role in inflammation is vital for disease management.
Purpose:
- To review experimental evidence on magnesium's modulation of cellular inflammatory events.
- To elucidate the mechanisms by which Mg influences inflammatory pathways.
- To connect Mg deficiency to various diseases through the lens of inflammation.
Summary:
- Severe Mg deficiency in rats rapidly induces a pro-inflammatory state, marked by immune cell activation and increased inflammatory mediators.
- Elevated Mg concentrations attenuate inflammatory responses, while Mg depletion enhances them.
- Mg's action as a calcium antagonist is a key molecular mechanism modulating intracellular calcium and subsequent inflammation.
Impact:
- Mg deficiency exacerbates conditions like atherosclerosis, hypertension, and endothelial dysfunction.
- Activated endothelium due to Mg deficiency may promote cancer cell metastasis.
- Inflammation serves as a unifying factor linking Mg's role in diverse pathological states.
