Alzheimer's Disease Risk Factor APOE4 Exerts Dimorphic Effects on Female Bone

Advanced Science, EarlyView.
In aging bone, osteocytes accumulate neurodegenerative risk factor Apolipoprotein E (APOE). A humanized version of the Alzheimer's disease risk allele APOE4 altered the mouse bone transcriptome and proteome, with effects in female bone surpassing the brain, including bone fragility due to suppressed osteocytic maintenance of bone quality, identifying ...

A multicenter, prospective, observational study to determine association of mesangial C1q deposition with renal outcomes in IgA nephropathy

Scientific Reports, 2021
It was reported that histopathologic lesions are risk factors for the progression of IgA Nephropathy (IgAN). The aim of this study was to investigate the relationships between mesangial deposition of C1q and renal outcomes in IgAN.

A Synergistic Hydrogel‐Microalgae Platform for Dual‐Targeting of Intestinal and Neuroimmune Dysfunction in Inflammatory Bowel Disease

Advanced Science, EarlyView.
A bioactive hydrogel incorporating Chlorella vulgaris and paeoniflorin within a carboxymethyl chitosan/sodium alginate matrix cross‐linked with genipin is developed for inflammatory bowel disease therapy. The hydrogel exhibits gastric stability and intestine‐responsive release.

Fc-Galactosylation of Human Immunoglobulin Gamma Isotypes Improves C1q Binding and Enhances Complement-Dependent Cytotoxicity

Frontiers in Immunology, 2017
Binding of the complement component C1q to the CH2 domain of antigen-bound immunoglobulin gamma (IgG) activates the classical complement pathway and depends on its close proximity to Fc fragments of neighboring antibodies. IgG subclasses contain a highly

Prmt6 Deficiency or Inhibition Restores Microglial Homeostasis and Promotes Scar‐Limited Repair in Adult Spinal Cord Injury

Advanced Science, EarlyView.
After spinal cord injury, adult microglia remain persistently activated with chronic PRMT6 (protein arginine methyltransferase 6) upregulation. Prmt6 deficiency or inhibition reestablishes microglial homeostasis and promotes a scar‐limited repairment, enhancing axonal regrowth.

Natural Resistance to Ovarian Hyperstimulation Syndrome in Estrildid Finches Reveals Macrophage GPR183 as a Potential Therapeutic Target

Advanced Science, EarlyView.
Ovarian macrophage depletion reverses OHSS resistance in estrildid finches and exacerbates OHSS symptoms in rats. Activating macrophage GPR183 alleviates OHSS by reducing pro‐inflammatory factors, increasing immunomodulatory molecules, remodeling CD44/SDC4‐mediated communication, and restoring immune homeostasis.

Deciphering the fine details of C1 assembly and activation mechanisms: 'mission impossible'?

Frontiers in Immunology, 2014
The classical complement pathway is initiated by the large (~800kDa) and flexible multimeric C1 complex. Its catalytic function is triggered by the hetero-tetramer of proteases C1r2s2, which is associated to the C1q sensing unit, a complex assembly of 18

C1q, Autoimmunity and Apoptosis

Immunobiology, 2002
Deficiency of classical pathway complement components displays a hierarchical association with the development of systemic lupus erythematosus (SLE). Individuals with deficiency of C1q, the first component of the classical pathway of activation, have the highest prevalence of SLE and the most severe manifestations of the disease. However, complement is

Immune Complexes Shape the Pathogenicity of Autoantibodies in Systemic Autoimmune Diseases: Insights From an FcγRIIIA‐Reporter Assay

Arthritis &Rheumatology, EarlyView.
Objective Immune complexes (ICs), formed by autoantigen and autoantibody, play a pathogenic role in systemic autoimmune diseases through stimulation of Fcγ receptors (FcγR). However, studies investigating bioactivity of circulating ICs across various diseases remain limited.
