Insights into IgM-mediated complement activation based on in situ structures of IgM-C1-C4b [PDF]

open access: yes, 2019
Antigen binding by serum Ig-M (IgM) protects against microbial infections and helps to prevent autoimmunity, but causes life-threatening diseases when mistargeted. How antigen-bound IgM activates complement-immune responses remains unclear.

Freeze-dried plasma proteins are stable at room temperature for at least 1 year

open access: yesClinical Proteomics, 2017
Thirty human EDTA plasma samples from male and female subjects ranging in age from 24 to 74 years were collected on ice, processed ice cold and stored frozen at −80 °C, in liquid nitrogen (LN2), or freeze dried and stored at room temperature in a ...

Comparison of Receptor‐Mediated Endocytosis and Its Application to Enhance DNA Transfection by TFAMoplex

open access: yesAdvanced NanoBiomed Research, EarlyView.
We developed an assay to distinguish cellular binding from internalization. Compatible with microscopy and high‐throughput screening, the method identifies ligand‐mediated uptake. Applying top candidates to a protein‐based DNA carrier enhanced transfection efficiency, providing a rational strategy to improve non‐viral gene delivery systems.

C4Bgene influences intestinal microbiota through complement activation in patients with paediatric-onset inflammatory bowel disease [PDF]

open access: yes, 2017
SummaryComplement C4 genes are linked to paediatric inflammatory bowel disease (PIBD), but the mechanisms have remained unclear. We examined the influence of C4B gene number on intestinal microbiota and in-vitro serum complement activation by intestinal ...

Opposite Profiles of Complement in Antiphospholipid Syndrome (APS) and Systemic Lupus Erythematosus (SLE) Among Patients With Antiphospholipid Antibodies (aPL)

open access: yesFrontiers in Immunology, 2019
APS is the association of antiphospholipid antibodies (aPL) with thromboses and/or recurrent pregnancy loss (RPL). Among patients with SLE, one-third have aPL and 10–15% have a manifestation of secondary APS.

Higher Complement C4 Gene Copy Number Constitutes a Shared Genetic Risk Factor for Giant Cell Arteritis and IgA Vasculitis

open access: yesArthritis &Rheumatology, EarlyView.
Objective Low copy number (CN) of complement C4 isoforms and high CN of retroviral HERV‐K elements are known risk factors for many immune‐mediated inflammatory diseases (IMIDs), often showing sex‐biased effects. Here, we assessed whether CN variation within the C4 gene contributes to giant cell arteritis (GCA) and IgA vasculitis (IgAV), two complex ...

Recent Advances in Photocatalyst‐Driven Protein Labeling and Proximity Mapping

open access: yesThe Chemical Record, EarlyView.
Photocatalyst‐driven protein labeling and proximity mapping have rapidly advanced as powerful strategies for spatiotemporal control in complex biological environments. This review integrates recent developments across single‐electron transfer and energy transfer‐based mechanisms and highlights how catalyst design, reactive intermediates, and diffusion ...

Table_1_Human Complement C4B Allotypes and Deficiencies in Selected Cases With Autoimmune Diseases.docx [PDF]

open access: yes, 2021
Human complement C4 is one of the most diverse but heritable effectors for humoral immunity. To help understand the roles of C4 in the defense and pathogenesis of autoimmune and inflammatory diseases, we determined the bases of polymorphisms including ...

The Airway Transcriptome in Type 2 Cytokine Biomarker‐High and ‐Low Severe Asthma

open access: yesAllergy, EarlyView.
This study distinguishes severe asthma–related airway transcriptomic changes from the effects of high‐dose ICS. Most dysregulated genes in severe asthma show concordance with corticosteroid responses. Corticosteroid‐resistant T2‐high asthma featured T2‐high and epithelial barrier gene upregulation, while T2‐low asthma featured Th1/IL‐17 signatures. ASM,
