The carbohydrate-linked phosphorylcholine of the parasitic nematode product ES-62 modulates complement activation [PDF]

open access: yes, 2016
Parasitic nematodes manufacture various carbohydratelinked phosphorylcholine (PCh)-containing molecules, including ES-62, a protein with an N-linked glycan terminally substituted with PCh.

Increased frequency of the null allele at the complement C4b locus in autism [PDF]

open access: yesClinical and Experimental Immunology, 1991
SUMMARY Associations between C4 deficiency and autoimmune disorders have been found over the past several years. Since autism has several autoimmune features, the frequencies of null (no protein produced) alleles at the C4A and C4B loci were studied in 19 subjects with autism and their family members.

Neoadjuvant Therapy‐Induced Remodeling in Pancreatic Ductal Adenocarcinoma: Multimodal Spatial Analysis and Prognosis

open access: yesCancer Science, Volume 117, Issue 4, Page 1167-1177, April 2026.
Using integrated spatial pathomics and transcriptomics, we show that neoadjuvant therapy (NAT) in pancreatic ductal adenocarcinoma (PDAC) induces substantial tumor microenvironment remodeling that is not captured by tumor regression grading (TRG) alone.

Visualization of human C4b-binding protein and its complexes with vitamin K-dependent protein S and complement protein C4b. [PDF]

open access: yesProceedings of the National Academy of Sciences, 1983
C4b-binding protein (C4bp) participates in the regulation of the C3 convertase of the classical pathway of complement. By binding to C4b, which is one of the structural subunits of this enzyme, C4bp accelerates the decay-dissociation of the enzyme and renders C4b susceptible to degradation by factor I (C3b inactivator).

Manin's conjecture for a class of singular cubic hypersurfaces

open access: yes, 2017
Let $n$ be a positive multiple of $4$. We establish an asymptotic formula for the number of rational points of bounded height on singular cubic hypersurfaces $S_n$ defined by $$ x^3=(y_1^2 + \cdots + y_n^2)z . $$ This result is new in two aspects: first,

Identification of Key Genes Involved in Lactic Acid Metabolism in Periodontitis Based on Bioinformatics Analysis

open access: yesJournal of Cellular and Molecular Medicine, Volume 30, Issue 8, April 2026.
ABSTRACT Lactic acid metabolism correlates with periodontitis progression. Using machine learning (LASSO and SVM‐RFE) on GSE16134 and GSE173078 datasets, CFI and COQ2 were identified as key genes, with good diagnostic performance (AUC > 0.75). GSEA linked these genes to MAPK signalling, endocytosis, and ubiquitin‐mediated proteolysis.

Anti-HLA antibodies with complementary and synergistic interaction geometries promote classical complement activation on platelets

open access: yesHaematologica, 2019
High titers of HLA antibodies are associated with platelet refractoriness, causing poor platelet increments after transfusions in a subset of patients with HLA antibodies.

Global Transcriptomic Profiling of Bovine Endometrial Immune Response In Vitro. II. Effect of Bovine Viral Diarrhea Virus on the Endometrial Response to Lipopolysaccharide [PDF]

open access: yes, 2015
Infection with noncytopathic bovine viral diarrhea virus (ncpBVDV) is associated with uterine disease and infertility. This study investigated the influence of ncpBVDV on immune functions of the bovine endometrium by testing the response to bacterial ...

A Dual‐Phase Approach to Facial Rejuvenation Integrating Contouring and Ligamentous (CL Code) Anchoring With a Polycaprolactone‐Based Collagen Stimulator

open access: yesJournal of Cosmetic Dermatology, Volume 25, Issue 4, April 2026.
ABSTRACT Background Facial aging reflects concurrent skeletal remodeling, fat redistribution, and attenuation of retaining ligaments. Volume‐oriented fillers may restore contours but often underaddress structural support. Objective To describe the CL Code, a dual‐phase injectable protocol combining Contouring (C) and Ligamentous anchoring (L), using a ...

How Escherichia coli Circumvent Complement-Mediated Killing

open access: yesFrontiers in Immunology, 2017
Complement is a crucial arm of the innate immune response against invading bacterial pathogens, and one of its main functions is to recognize and destroy target cells.
