Pathological Roles of Astrocytes in Traumatic Brain Injury

open access: yesCNS Neuroscience &Therapeutics, Volume 32, Issue 4, April 2026.
TBI induces intrinsic astrocytic changes, including reactive astrogliosis, A1 and A2 polarization, ion channels activation, pathological edema, oxidative stress, and metabolic dysregulation. These injury‐responsive astrocytes regulate neuroinflammation and tissue remodeling through dynamic crosstalk with microglia, macrophages, vascular endothelial ...

Islet Amyloid Polypeptide Triggers Limited Complement Activation and Binds Complement Inhibitor C4b-binding Protein, Which Enhances Fibril Formation [PDF]

open access: yesJournal of Biological Chemistry, 2011
Islet amyloid polypeptide (IAPP) is synthesized in pancreatic β-cells and co-secreted with insulin. Aggregation and formation of IAPP-amyloid play a critical role in β-cell death in type 2 diabetic patients. Because Aβ-fibrils in Alzheimer disease activate the complement system, we have here investigated specific interactions between IAPP and ...

REV-ERBα mediates complement expression and diurnal regulation of microglial synaptic phagocytosis

open access: yeseLife, 2020
The circadian clock regulates various aspects of brain health including microglial and astrocyte activation. Here, we report that deletion of the master clock protein BMAL1 in mice robustly increases expression of complement genes, including C4b and C3 ...

Fasciola hepatica is refractory to complement killing by preventing attachment of mannose binding lectin (MBL) and inhibiting MBL-associated serine proteases (MASPs) with serpins.

open access: yesPLoS Pathogens, 2022
The complement system is a first-line innate host immune defence against invading pathogens. It is activated via three pathways, termed Classical, Lectin and Alternative, which are mediated by antibodies, carbohydrate arrays or microbial liposaccharides,

Spirochetal Lipoproteins and Immune Evasion. [PDF]

open access: yes, 2017
Spirochetes are a major threat to public health. However, the exact pathogenesis of spirochetal diseases remains unclear. Spirochetes express lipoproteins that often determine the cross talk between the host and spirochetes.

C4B null alleles are not associated with genetic polymorphisms in the adjacent gene CYP21A2 in autism

open access: yesBMC Medical Genetics, 2008
Background Research indicates that the etiology of autism has a strong genetic component, yet so far the search for genes that contribute to the disorder, including several whole genome scans, has led to few consistent findings.

Risk Factors for Recurrence of the Anti‐Synthetase Syndrome Related Interstitial Lung Disease

open access: yesImmunity, Inflammation and Disease, Volume 14, Issue 4, April 2026.
ABSTRACT Purpose This current study aimed to detect the risk factors for recurrence of the anti‐synthetase syndrome related interstitial lung disease (ASSD‐ILD). Methods Patients who were diagnosed with ASSD‐ILD and achieved the improving standards after treatment at a single clinical center from January 1, 2017 to January 1, 2022 were retrospectively ...

Hyaluronic Acid Decoration Facilitates CD44‐Mediated Targeting and Alters Protein Corona Formation of Extracellular Vesicles

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 4, April 2026.
ABSTRACT Cell recognition and uptake of extracellular vesicles (EVs) is mediated by a variety of surface molecules. Growing interest has recently been drawn towards glycan structures on EVs. Hyaluronic acid (HA) is a negatively charged glycosaminoglycan that can decorate the surface of EVs from different origins.

Functional recruitment of human complement inhibitor C4B-binding protein to outer membrane protein Rck of Salmonella. [PDF]

open access: yesPLoS ONE, 2011
Resistance to complement mediated killing, or serum resistance, is a common trait of pathogenic bacteria. Rck is a 17 kDa outer membrane protein encoded on the virulence plasmid of Salmonella enterica serovars Typhimurium and Enteritidis.

Fast-slow bursters in the unfolding of a high codimension singularity and the ultra-slow transitions of classes

open access: yes, 2016
Bursting is a phenomenon found in a variety of physical and biological systems. For example, in neuroscience, bursting is believed to play a key role in the way information is transferred in the nervous system.
