Insights
Cluster of Differentiation (CD) 93 is linked to cardiovascular disease (CVD) risk factors and conditions. Further research is needed to confirm CD93
Area of Science:
- Cardiovascular Science
- Immunology
- Molecular Biology
Background:
- Cluster of Differentiation (CD) 93, also known as complement protein 1 q subcomponent receptor (C1qR1), is a transmembrane glycoprotein with soluble forms (sCD93).
- Emerging research suggests a role for CD93 in the pathogenesis of cardiovascular disease (CVD).
Approach:
- A systematic review was conducted, searching PubMed, EMBASE, and Web of Science databases up to February 2023.
- Included human studies investigated associations between CD93 (protein levels or genetic polymorphisms) and cardiovascular risk factors or CVD outcomes.
- Data collection and analysis were performed by two independent reviewers.
Key Points:
- Fifteen studies were included, examining CD93's association with hypertension, dyslipidemia, obesity, heart failure, coronary artery disease, and ischemic stroke.
- The review assessed CD93 at both proteomic and genomic levels.
- Current evidence suggests potential links between CD93 and cardiovascular health.
Conclusions:
- While promising, the existing studies are limited in quality and scope.
- Definitive conclusions regarding the diagnostic or prognostic value of CD93 in CVD cannot be drawn yet.
- Further high-quality research is warranted to elucidate the role of CD93 in cardiovascular medicine.
Introduction:
Cluster of Differentiation (CD) 93 (also known as complement protein 1 q subcomponent receptor C1qR1 or C1qRp) is a transmembrane glycoprotein that can also be present in a soluble (sCD93) form. Recent studies have investigated the role of this protein in cardiovascular disease (CVD). The present systematic review aims to assess the associations between CD93 and cardiovascular (CV) risk factors and disease at both the proteomic and genomic levels.
Methods:
We conducted systematic searches in the PubMed, EMBASE, and Web of Science databases to identify all human studies since inception to February 2023 that investigated the role of CD93 in CV risk factors, CVD, and CV-associated outcomes. The data collection and analysis have been independently conducted by two reviewers. The search terms included: cardiovascular, heart failure, acute stroke, myocardial infarction, stroke, peripheral artery disease, cardiovascular death, MACE, hypertension, metabolic syndrome, hyperuricemia, diabetes, cd93, c1qr, C1qR1, complement protein 1 q subcomponent receptor.
Results:
A total of 182 references were identified, and 15 studies investigating the associations between CD93 protein levels or CD93 genetic polymorphisms and the development or prevalence of CV risk factors (i.e., hypertension, dyslipidemia, and obesity) and CVD (i.e., heart failure, coronary artery disease, and ischemic stroke) were included. Although promising, the quality and dimension of the analyzed studies do not allow for a definitive answer to the question of whether CD93 may hold diagnostic and prognostic value in CVD.
