Serum C1q concentration is associated with disease activity in Chinese Takayasu arteritis patients: A case‐control study

open access: yesHealth Science Reports, 2021
Background C1q is a crucial component of the classical complement pathway. This study is the first to assess the association between disease activity and serum levels of C1q in Chinese Takayasu arteritis (TA) patients.

Turning Unpredictable Biomolecule Adsorption to Controlled Corona Formation: Focus on Carbon Nanomaterials

open access: yesAdvanced Materials, EarlyView.
Controlling the protein corona formation onto carbon nanomaterials (CNMs) enhances their functionalities as platforms for cancer theranostics. Here, we reviewed the effects of the intrinsic and acquired properties of CNMs on protein corona formation, the consequent biological and toxicological outcomes, and the strategies to reshape corona formation ...

Structural and functional characterization of a single-chain form of the recognition domain of complement protein C1q

open access: yesFrontiers in Immunology, 2016
Complement C1q is a soluble pattern recognition molecule comprising six heterotrimeric subunits assembled from three polypeptide chains (A, B, and C). Each heterotrimer forms a collagen-like stem prolonged by a globular recognition domain.

Two Routes to Land: Genomic Underpinnings of Parallel Aerial Egg Deposition in Aquatic Old‐World Pila and New‐World Pomacea (Ampullariidae)

open access: yesAdvanced Science, EarlyView.
Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

MINI-REVIEW: SYSTEMIC LUPUS ERYTHEMATOSUS AND DEFICIENCIES OF EARLY COMPONENTS OF THE COMPLEMENT CLASSICAL PATHWAY

open access: yesFrontiers in Immunology, 2016
The complement system plays an important role in the innate and acquired immune response against pathogens. It consists of more than 30 proteins found in soluble form or attached to cell membranes. Most complement proteins circulate in inactive forms and

Astrocytic Phenotypic Switching in Posterior Piriform Cortex Orchestrates Bone Cancer Pain–Depression Comorbidity via Purinergic–Noradrenergic Signaling

open access: yesAdvanced Science, EarlyView.
Bone cancer pain and depression share a common origin: astrocytic A2‐to‐A1 transition in the posterior piriform cortex. This phenotypic shift disrupts the ATP–adenosine–A2AR–norepinephrine axis, simultaneously driving nociceptive and affective dysfunction.

The role of complement components (C1q, C3a, MAC) activation in earlyand late-onset preeclampsia and fetal growth restriction

open access: yesАкушерство, гинекология и репродукция
Introduction. Preeclampsia (PE) remains one of the leading causes for maternal and perinatal morbidity and mortality. Placental insufficiency associated with impaired trophoblast invasion, hypoperfusion, and inflammatory endothelial activation is ...

Emerging and novel functions of complement protein C1q

open access: yesFrontiers in Immunology, 2015
Complement protein C1q, the recognition subcomponent of the classical pathway, performs a diverse range of complement and non-complement functions. It can bind various ligands derived from self, non-self and altered-self and modulate the functions of ...

A Blood‐Derived Factor Rescues ALS: Platelet Factor 4 Activates OPTN‐Dependent Autophagy to Clear SOD1 Aggregates Independently of PINK1

open access: yesAdvanced Science, EarlyView.
Systemic platelet factor 4 (PF4) is significantly depleted in amyotrophic lateral sclerosis (ALS). Peripheral PF4 replenishment restores central proteostasis by driving OPTN‐dependent, PINK1‐independent selective autophagy in motor neurons. This intervention effectively clears toxic SOD1 aggregates, blunts glial activation, and preserves neuromuscular ...

Endogenous complement-activating IgM is not required for primary antibody responses but promotes plasma cell differentiation and secondary antibody responses to a large particulate antigen in mice

open access: yesFrontiers in Immunology
Lack of complement factor C1q of the classical pathway results in severely impaired primary antibody responses. This is a paradox because antibodies, especially IgM, are the most efficient activators of the classical pathway and very little specific IgM ...
