“…A modified and fully validated two-dimensional liquid chromatography-tandem mass spectrometry (LC-MS) assay was used to quantify plasma levels of ceramides C24:0, C22:0, and C16:0 according to previous published methods. 17 Linear dynamic ranges for ceramides C16:0, C22:0, and C24:0 in this assay were 0.01 to 2, 0.04 to 8, and 0.1 to 20 µg/mL, respectively. The intraassay and interassay precisions were within 6.9%, 7.6% and 7.8% coefficient of variation for C24:0, C22:0 and C16:0, respectively.…”

“…Recently, attention has focused on the role of circulating ratios of a very‐long‐chain to long‐chain ceramides as biomarkers for major vascular events and the possibility that these ratios may be of greater diagnostic and prognostic value for cardiovascular outcomes compared to total ceramide levels or concentrations of individual ceramide species. It has been contended, but is unproven, that the adverse cognitive effects of ceramides may be related to the relative proportions of circulating very long‐chain to long‐chain fatty acyl chains rather than simply due to elevated total ceramide levels .…”

Background We determined the association between ratios of plasma ceramide species of differing fatty‐acyl chain lengths and incident dementia and Alzheimer’s disease (AD) dementia in a large, community‐based sample. Methods We measured plasma ceramide levels in 1892 [54% women, mean age 70.1 (SD 6.9) yr.] dementia‐free Framingham Offspring Study cohort participants between 2005 and 2008. We related ratios of very long‐chain (C24:0, C22:0) to long‐chain (C16:0) ceramides to subsequent risk of incident dementia and AD dementia. Structural MRI brain measures were included as secondary outcomes. Results During a median 6.5 year follow‐up, 81 participants developed dementia, of whom 60 were diagnosed with AD dementia. In multivariable Cox‐proportional hazards analyses, each standard deviation (SD) increment in the ratio of ceramides C24:0/C16:0 was associated with a 27% reduction in the risk of dementia (HR 0.73, 95% CI 0.56–0.96) and AD dementia (HR 0.73, 95% CI 0.53–1.00). The ratio of ceramides C22:0/C16:0 was also inversely associated with incident dementia (HR per SD 0.75, 95% CI 0.57–0.98), and approached statistical significance for AD (HR 0.73, 95% CI 0.53–1.01, P = 0.056). Higher ratios of ceramides C24:0/C16:0 and C22:0/C16:0 were also cross‐sectionally associated with lower white matter hyperintensity burden on MRI (−0.05 ± 0.02, P = 0.02; −0.06 ± 0.02, P = 0.003; respectively per SD increase), but not with other MRI brain measures. Conclusions Higher plasma ratios of very long‐chain to long‐chain ceramides are associated with a reduced risk of incident dementia and AD dementia in our community‐based sample. Circulating ceramide ratios may serve as potential biomarkers for predicting dementia risk in cognitively healthy adults.

Cardiometabolic disorders contribute to the global burden of cardiovascular diseases. Emerging sphingolipid metabolites like sphingosine‐1‐phosphate (S1P) and its receptors, S1PRs, present a dynamic signalling axis significantly impacting cardiac homeostasis. S1P's intricate mechanisms extend to its transportation in the bloodstream by two specific carriers: high‐density lipoprotein particles and albumin. This intricate transport system ensures the accessibility of S1P to distant target tissues, influencing several physiological processes critical for cardiovascular health. This review delves into the diverse functions of S1P and S1PRs in both physiological and pathophysiological conditions of the heart. Emphasis is placed on their diverse roles in modulating cardiac health, spanning from cardiac contractility, angiogenesis, inflammation, atherosclerosis and myocardial infarction. The intricate interplays involving S1P and its receptors are analysed concerning different cardiac cell types, shedding light on their respective roles in different heart diseases. We also review the therapeutic applications of targeting S1P/S1PRs in cardiac diseases, considering existing drugs like Fingolimod, as well as the prospects and challenges in developing novel therapies that selectively modulate S1PRs.

Ceramides and cardiorespiratory (CR) fitness are both related to cardiovascular diseases. The associations of three blood plasma ceramides (C16:0, C22:0, and C24:0) with CR fitness in the population‐based Study of Health in Pomerania (SHIP‐START‐1; n = 1,102; mean age 50.3 years, 51.5% women) are investigated. In addition, subgroup analysis according to age (</≥54 years) and sex (female/male) is performed. Ceramides are quantified by liquid chromatography/mass spectrometry (LC/MS). CR fitness is assessed by a cardiopulmonary exercise test. Sex and age independent associations are found for higher levels of C24:0 and C24:0/C16:0 ratio with higher maximal oxygen consumption (VO2peak) kg−1 and oxygen consumption at the anaerobic threshold (VO2@AT1) as well as for the relation of C24:0/C16:0 with maximum workload (Wattmax kg−1). In contrast, age/sex subgroup specific inverse associations with Wattmax kg−1 are found in women <54 years for C22:0, while a positive association in men ≥54 years. Higher levels of C24:0 are associated with higher Wattmax kg−1, except for women <54 years, where no significant association can be found. The findings suggest that the use of single ceramides as cardiovascular biomarkers may be inferior, compared to ceramide ratio C24:0/C16:0. Therefore C24:0/C16:0 ratio may be a more suitable and robust cardiovascular biomarker and should be preferred over single ceramides.
