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

Cancer‐Specific Antihuman Podoplanin Antibody chLpMab‐2f Exerts Antitumor Effects Against Pleural Mesothelioma

Cancer Science, EarlyView.
Cancer‐specific antihuman podoplanin antibody chLpMab‐2f exerted antibody‐dependent cellular cytotoxicity and complement‐dependent cytotoxicity against pleural mesothelioma (PM) cell lines. Additionally, chLpMab‐2f inhibited tumor progression in mice with subcutaneously and intrathoracically transplanted human PM cells.

Beyond diabetes and obesity: GLP‐1 receptor agonists in disrupting the vicious cycle of metabolic dysfunction and neuroinflammation

Diabetes, Obesity and Metabolism, EarlyView.
Abstract Neurodegenerative diseases, including debilitating conditions like Alzheimer's and Parkinson's, are characterized by progressive neuronal loss, a process fundamentally driven by persistent chronic neuroinflammation and central metabolic dysfunction.

C1q neutralization during epileptogenesis attenuates complement‐mediated synaptic elimination and epileptiform activity

Epilepsia, EarlyView.
Abstract Objective Accumulating evidence indicates that aberrant C1q‐C3 complement signaling in microglia and astrocytes drives synaptic dysfunction and neuronal loss. C1q‐mediated synaptic dysfunction disrupts neuronal circuitry balance and can lead to network hyperexcitability in epilepsy.

Anti-C1q Antibodies as Occurring in Systemic Lupus Erythematosus Could Be Induced by an Epstein-Barr Virus-Derived Antigenic Site

Frontiers in Immunology, 2019
Previous infection with Epstein-Barr virus (EBV) is believed to trigger autoimmunity and to drive autoantibody generation as occurring in patients with systemic lupus erythematosus (SLE). Complement C1q and autoantibodies targeting it (anti-C1q) are also

Conditional deletion of the multiple sclerosis susceptibility gene ATXN1 identifies cell‐autonomous effects in the B‐cell compartment

The FEBS Journal, EarlyView.
Ataxin‐1 is a polyglutamine protein associated with the etiology of spinocerebellar ataxia type 1 (SCA1) that has been recently found implicated in the risk of developing the autoimmune disorder multiple sclerosis (MS). Here, we took a conditional knockout approach to ablate ataxin‐1 exclusively in the B‐cell compartment and we found that this protein ...

Classical complement cascade initiating C1q protein within neurons in the aged rhesus macaque dorsolateral prefrontal cortex

Journal of Neuroinflammation, 2020
Background Cognitive impairment in schizophrenia, aging, and Alzheimer’s disease is associated with spine and synapse loss from the dorsolateral prefrontal cortex (dlPFC) layer III.

Activation of the Lectin Pathway Drives Persistent Complement Dysregulation in Long COVID

Immunology, EarlyView.
The complement cascade, a series of blood proteins that assists in the recognition and neutralisation of pathogens, either independently or in conjunction with antibodies, is persistently activated in patients with long COVID. We found that blood plasma samples from patients with long COVID contained elevated concentrations of the mannan‐binding lectin‐
