Emerging Perspectives on Platelet-Activating Factor in Relation to Magnesium Levels at the Cellular, Tissue, and Systemic Levels in Disease States

Magnesium is an essential micronutrient that exerts fundamental roles at both the cellular and tissue levels, with broad therapeutic and preventive implications across a range of pathological conditions. Accumulating clinical and experimental evidence indicates that optimal magnesium homeostasis modulates key pathophysiological processes and serves as both a biological and prognostic marker in disorders such as stroke, myocardial infarction, type 2 diabetes mellitus, and renal failure. These disease states commonly originate from two major etiological determinants-hypertension and atherosclerosis-which share a unifying pro-inflammatory mediator: platelet-activating factor (PAF). PAF plays a central role in vascular inflammation by promoting platelet aggregation, macrophage infiltration, leukocyte adhesion, and vasomotor dysregulation. Importantly, magnesium demonstrates an inverse association with both platelet aggregation and PAF activity, underscoring its protective capacity in mitigating vascular inflammation and preserving endothelial function. The objective of this updated literature review is to elucidate the antagonistic interplay between magnesium and PAF, with a focus on its physiological and therapeutic significance across multiple organ systems. While emerging data support a modulatory role of magnesium in PAF-mediated inflammatory pathways, current evidence remains limited. Therefore, further mechanistic, pharmacological, and clinical investigations are warranted to clarify the multifaceted role of magnesium in attenuating PAF-driven disease processes.
