[PMID: 38111574 PMCID: PMC10726124 DOI: 10.3389/fimmu.2023.1271741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2023] [Accepted: 11/17/2023] [Indexed: 12/20/2023] Open
Abstract
Sulfatides are a type of sulfated glycosphingolipid that are secreted with lipoproteins into the serum. These molecules are involved in the inflammatory pathway of vessels in addition to coagulation and platelet aggregation. Previous studies have proposed that sulfatides play a pivotal role in regulating inflammation-related disorders. Systemic vasculitis (SV) diseases are generally caused by autoimmune diseases and often involve kidney vasculitis, which may lead to rapidly progressive kidney dysfunction and end-stage kidney disease. Our earlier pilot study revealed that the level of serum sulfatides (SSs) was significantly decreased in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), a representative disease-causing SV with kidney involvement (SVKI), especially in patients exhibiting active crescentic findings on kidney biopsy. To further explore the clinical significance of an association between SS and SVKI, we analyzed and compared the SS level of patients with various SVKI diseases in this retrospective cohort study. Among patients admitted to our hospital between 2008 and 2021, we ultimately enrolled 26 patients with IgA vasculitis (IgAV), 62 patients with AAV, and 10 patients with anti-glomerular basement membrane disease (GBM) as examples of SVKI diseases, as well as 50 patients with IgA nephropathy (IgAN) and 23 donors for living kidney transplantation as controls. The mean ± standard deviation SS level in the donor, IgAN, IgAV, AAV, and GBM groups was 8.26 ± 1.72, 8.01 ± 2.21, 6.01 ± 1.73, 5.37 ± 1.97, and 2.73 ± 0.99 nmol/mL, respectively. Analysis of patients in the SVKI disease group showed that those with the crescentic class kidney biopsy finding exhibited a significantly lower SS level than did those with other class biopsy features. Additionally, the SS level had a higher detection ability for SVKI patients with crescentic class kidney biopsy findings (area under the receiver operating characteristic curve 0.90, 95% confidence interval 0.82-0.99) than did several other predictor candidates. Our results indicate that the SS level is decreased in more severe SVKI diseases and may be associated with active glomerular lesions in SVKI kidney biopsy samples.

Abstract
HIV infection has become a chronic and manageable disease due to the effective use of antiretroviral therapies (ART); however, several chronic aging-related comorbidities, including cognitive impairment, remain a major public health issue. However, these mechanisms are unknown. Here, we identified that glial and myeloid viral reservoirs are associated with local myelin damage and the release of several myelin components, including the lipid sulfatide. Soluble sulfatide compromised gap junctional communication and calcium wave coordination, essential for proper cognition. We propose that soluble sulfatide could be a potential biomarker and contributor to white matter compromise observed in HIV-infected individuals even in the current ART era.

Li J, Yin L, Qi X, Huang Y. Serum sulfatide as a biomarker of carotid atherosclerosis in patients with rheumatoid arthritis. Clin Chim Acta 2022; 534:6-13. [PMID: 35803336 DOI: 10.1016/j.cca.2022.06.030] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 06/16/2022] [Accepted: 06/27/2022] [Indexed: 11/03/2022]
Abstract
PURPOSE Rheumatoid arthritis (RA) patients have accelerated atherosclerosis (AS) leading to excess cardiovascular morbidity and mortality, but traditional risk factors for cardiovascular disease (CVD) are invalid to explain the problem. Sulfatides, as major components of serum lipoproteins, are synthesized in the liver. These molecules are reported to play an important role in the development of AS, thrombogenesis, and inflammation. However, it is unclear whether sulfatides are responsible for such issue. To elucidate the possible association between serum sulfatide and the accelerated progress of AS, evaluated by carotid intima-media thickness (CIMT), and ascertain the related mechanism underlying the correlation in RA cases. METHODS We performed an observational study of 144 patients with RA and 120 sex and age-matched controls. Meanwhile, 107 patients (of the 144 RA patients enrolled at baseline) were invited to undergo a second measurement after 12 months. Serum sulfatide levels of all the enrolled subjects were quantified by mass spectrometry after they were converted into lysosulfatides (LS), and then calculated as the sum of the levels of seven LS molecular species. Serum oxidative stress marker, malondialdehyde (MDA) was detected by ELISA. We subsequently statistically analyzed the causalities between carotid AS and clinical parameters, and the association of serum sulfatide with other variables. Multivariable logistic regression analysis was finally employed by taking all factors to identify independent determinant for carotid atherosclerotic plaque and serum sulfatide level. RESULTS A gradual declined trend in serum sulfatide levels was observed in control subjects, non-plaque group, and the plaque group (8.56 ± 1.37 nmol/mL, 5.63 ± 1.57 nmol/mL, 3.18 ± 1.32 nmol/mL, respectively, p < 0.01), along with an increased value of CIMT (0.63 ± 0.07 mm, 0.92 ± 0.14 mm, 1.43 ± 0.22 mm, respectively, p < 0.01). Meanwhile, a negative linear correlation between CIMT and serum sulfatide was further confirmed by Spearman's analysis (r = -0.622, p < 0.01). Eventually, multivariate logistic regression analysis identified serum MDA as the only independent factor for the abnormal level of serum sulfatide, and serum sulfatide was detected as a significant protective factor for the occurrence of carotid plaques in RA cases (p < 0.01), which was confirmed repeatedly by our cross-sectional and longitudinal studies. CONCLUSION Excessive abnormal levels of oxidative stress decreased serum sulfatide levels, followed by a high occurrence of AS in RA patients. Serum sulfatide level might be useful as a predictor (biomarker) for the progression of AS in RA cases.

Peptide Antagonists for P-selectin Discriminate between Sulfatide-Dependent Platelet Aggregation and PSGL-1-Mediated Cell Adhesion. J Clin Med 2019; 8:jcm8081266. [PMID: 31434351 PMCID: PMC6722823 DOI: 10.3390/jcm8081266] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2019] [Revised: 08/08/2019] [Accepted: 08/16/2019] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND Membrane-exposed sulfatides are proposed to contribute to P-selectin-dependent platelet aggregation. Here, we demonstrated that P-selectin-mediated platelet aggregation on a collagen-coated surface under flow indeed depended on sulfatides and that this interaction differed considerably from the interaction of P-selectin with P-selectin Glycoprotein Ligand-1 (PSGL-1), which underlies leukocyte-endothelium adhesion. METHODS AND RESULTS Upon platelet activation, sulfatides were translocated to the platelet surface to form focal hot-spots. Interestingly, P-selectin was observed to exclusively interact with liposomes with a sulfatide density higher than 21% (w/w), indicating that the binding profile of P-selectin for sulfatide-rich liposomes was dependent on sulfatide density. Sulfatide-liposome binding to P-selectin and sulfatide/P-selectin-dependent platelet aggregation was blunted by peptide antagonists, carrying the EWVDV motif within N-terminal extensions, such as CDVEWVDVSC (half maximal inhibitory concentration IC50 = 0.2 μM), but not by the EWVDV core motif itself (IC50 > 1000 μM), albeit both being equally potent inhibitors of PSGL-1/P-selectin interaction (IC50= 7-12 μM). CONCLUSIONS Our data suggest that the sulfatide/P-selectin interaction implicates multiple binding pockets, which only partly overlap with that of PSGL-1. These observations open ways to selectively interfere with sulfatide/P-selectin-dependent platelet aggregation without affecting PSGL-1-dependent cell adhesion.

Abstract
Aims: ST-segment elevation myocardial infarction (STEMI) is an acute inflammatory and thrombotic disease due to coronary artery atherosclerotic lesions. Studies have established the correlation of serum sulfatides with inflammation, thrombogenesis, and atherosclerosis. We observed that serum sulfatides level significantly increased in STEMI patients. In this study, we try to identify the relationship of serum sulfatides level on clinical outcomes of patients in STEMI. Methods: Serum sulfatides level was monitored in 370 inpatients within 24 h of STEMI onset. On the basis of the level of serum sulfatides that was below 10 µmol/L in the normal population, the patients were divided into two groups with the median value of 15.2 µmol/L; low sulfatide group [serum sulfatides level ≤ 15.2 µmol/L (n = 200)] and high sulfatide group [serum sulfatides level > 15.2 µmol/L (n = 170)]. Patients' baseline characteristics, in-hospital outcomes, and late major adverse cardiovascular events (MACE) were analyzed. Independent incident for in-hospital death and late adverse events were modeled by multivariate logistic and Cox regression analysis. Results: Between the two groups, there were no differences in the angiographic characteristics, percutaneous coronary intervention (PCI) results, and in-hospital recovery. However, high serum sulfatides level is positively correlated with increased rate of in-hospital death (OR 0.971; 95% CI 0.926–0.990, p = 0.019). In addition, this group of patients has more cumulative incidences of target vessel revascularization (TVR) (23% vs. 8%, p < 0.05) and increased overall MACE (28% vs. 10%, p < 0.05). Cox regression analysis indicated that high serum sulfatides level contributes to TVR and overall MACE. Conclusions: Elevated serum sulfatides level positively correlate with in-hospital death and complications (TVR and MACE) in STEMI patients.

Abstract
There is a positive association between sulfatide and atherosclerosis in an animal model for human familial hypercholesterolemia. Carotid intima-media thickness (IMT) is thought to be a marker of atherosclerosis in humans. We investigated the relationship between sulfatide and carotid IMT in heterozygous familial hypercholesterolemia (FH) patients. Thirty-five genetically-verified heterozygous patients with FH and 34 healthy controls were recruited into our study. We measured serum sulfatide levels, the carotid IMT, and conventional cardiovascular risk factors including obesity parameters, blood pressure, fasting blood glucose, and lipid profiles. Subjects with heterozygous FH had significantly elevated serum sulfatide, elevated total cholesterol, low-density lipoprotein cholesterol, and increased carotid IMT compared with control subjects. In patients with FH, univariate analysis showed that serum sulfatide was significantly correlated with carotid IMT. Multiple linear regression analysis indicated that serum sulfatide was the only independent predictor of carotid IMT in patients with FH. Patients with heterozygous FH had significantly higher carotid IMT and the level of serum sulfatide was independently associated with atherosclerotic progression. (R: 0.720, R(2): 0.503, p < 0.001).

Abstract
We investigated the changes in characteristics of neutrophil CD11b, monocyte CD11b, platelet CD62P, endothelin (ET), and neutrophil CD178 in patients with coronary heart disease (CHD) before and after primary coronary stenting. A total of 41 patients with CHD who underwent coronary stenting and 40 control subjects were enrolled in the study. In CHD patients, peripheral blood samples were taken 24 h before and 30 min, 24 h, and 72 h after successful coronary stenting. All markers were significantly elevated in patients with CHD compared with controls (P<0.05). Time-course studies revealed that the expressions of neutrophil CD11b, monocyte CD11b, platelet CD62P, and ET were lower at 30 min post-operation (PO) compared with that at 24 h before operation (BO) (P<0.05). All levels significantly increased from 30 min PO to 24 h PO (P<0.05) and decreased thereafter until 72 h PO (P>0.05). Time course changes in neutrophil CD11b levels after coronary stenting were significantly higher in patients with unstable angina pectoris than in patients with stable angina pectoris (P<0.05). CD11b levels were related to CD62P in patients with CHD (P<0.05). Neutrophil CD11b and monocyte CD11b levels were significantly increased in patients with CHD who underwent coronary stenting compared with controls (P<0.05). Results show that CD11b levels increased, meanwhile, the levels of CD62P and ET increased in CHD patients after coronary stenting. In addition, neutrophil CD178 levels of apoptosis factor in patients, which is important for regression of inflammation, remained high for a period of time after coronary stenting.
