Article Abstract

Background: Visceral leishmaniasis (VL), one of the neglected tropical diseases, is endemic in the Indian subcontinent. Ficolins are circulating serum proteins of the lectin complement system and involved in innate immunity.

Methods: We have estimated ficolin-2 serum levels and analyzed the functional variants of the encoding gene FCN2 in 218 cases of VL and in 225 controls from an endemic region of India.

Results: Elevated levels of serum ficolin-2 were observed in VL cases compared to the controls (adjusted P<0.0001). The genetic analysis revealed that the FCN2 structural variant +6359 C>T (p.T236M) was associated with VL (OR=2.2, 95% CI=1.23-7.25, P=0.008) and with high ficolin-2 serum levels. We also found that the FCN2*AAAC haplotype occurred more frequently among healthy controls when compared to cases (OR=0.59, 95%CI=0.37-0.94, P=0.023).

Conclusions: Our findings indicate that the FCN2 variant +6359C>T is associated with the occurrence of VL and that ficolin-2 serum levels are elevated in Leishmania infections.

Background: Type 2 inflammation has emerged as a pivotal mechanism for asthma, which involves both innate and adaptive immunity. Human ficolin (FCN)-2 (L-ficolin, P35) and its mouse homolog FCN-A are one of the major pattern recognition molecules of plasma/serum, acting as important initiators of the lectin complement system and playing important roles in immunity, including respiratory immunity. However, little is known about the role of FCN-2/A in allergic asthma.

Introduction: Proteomic evaluation of plasma samples could accelerate the identification of novel Alzheimer's disease (AD) biomarkers. We evaluated the novel NUcleic acid Linked Immuno-Sandwich Assay (NULISA) proteomic method in an ethnically diverse cohort.

Methods: Plasma biomarkers were measured with NULISA in the Human Connectome Project, a predominantly preclinical biracial community cohort in southwestern Pennsylvania.

The wide use of capsular polysaccharide (CPS) conjugate vaccines is causing serotype replacement and the emergence of serotype 35B is concerning because of its multidrug resistance. CPS of 35B is composed of pentasaccharide repeating units that are linked through phosphodiester linkages. One of the galactofuranose residues of the pentasaccharide is acetylated, which distinguishes it from the invasive serotype 35D lacking the acetyl ester.

Article Synopsis
  • The study aimed to understand how a specific genetic variation (SNP) in the FCN gene influences the risk of pre-eclampsia (PE) in pregnant Han nationality women, comparing 274 women with PE to 154 healthy controls.
  • Results showed that women with PE had significantly higher levels of body mass index, blood pressure, and various blood biochemical indicators compared to the control group.
  • In genotyping 23 SNP loci, the distribution of specific loci in the FCN2 and FCN3 genes showed significant differences between the two groups, suggesting a genetic component to PE susceptibility.

Angiogenic factors and the lectin pathway of complement in women with secondary recurrent pregnancy loss.

Article Synopsis
  • Preeclampsia may lead to poor remodeling of placental spiral arteries, which, combined with abnormal angiogenesis and excessive complement activation, contributes to recurrent pregnancy loss (RPL).
  • The study examines angiogenic factors and lectin complement pathways in early pregnancies of 76 women with secondary RPL and finds that certain biomarkers, like elevated VEGF levels, are linked to pregnancy loss.
  • Results indicate that inadequate placentation and impaired angiogenesis may underlie pregnancy losses in women experiencing secondary RPL, with a notable association between ficolin-2 levels and pregnancy outcomes, while Mannose-binding-lectin showed no significant correlation.
