The effects of tidal volume size and driving pressure levels on pulmonary complement activation: an observational study in critically ill patients

open access: yesIntensive Care Medicine Experimental, 2020
Background Mechanical ventilation can induce or even worsen lung injury, at least in part via overdistension caused by too large volumes or too high pressures.

Defining Targets for Complement Components C4b and C3b on the Pathogenic Neisseriae [PDF]

open access: yesInfection and Immunity, 2008
ABSTRACTComplement is a key arm of the innate immune defenses against the pathogenic neisseriae. We previously identified lipooligosaccharide onNeisseria meningitidisas an acceptor for complement C4b. Little is known about other neisserial targets for complement proteins C3 and C4, which covalently attach to bacterial surfaces and initiate opsonization

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 ...

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.

Serum Proteomic Signatures of Rheumatoid Arthritis Risk and Response: Analysis of a Rheumatoid Arthritis Interception Trial

open access: yesArthritis &Rheumatology, EarlyView.
Objective Our study objective was to identify serum protein signatures associated with progression to rheumatoid arthritis (RA) and response to abatacept in at‐risk individuals. Methods A total of 440 serum samples from 118 APIPPRA (Arthritis Prevention In the Preclinical Phase of RA with Abatacept) study participants were selected from baseline to RA ...

Role for Complement C5 in Eosinophilic Inflammation of Severe Asthma

open access: yesAllergy, EarlyView.
Complement activation module, particularly C5, is positively associated with eosinophilic inflammation in severe asthma cohorts. Elevated C5 expression correlates with poor lung function improvement and persistent eosinophilic inflammation. Mouse model studies confirm that C5 exacerbates eosinophilic inflammation, highlighting its potential as a ...

Neoadjuvant Therapy‐Induced Remodeling in Pancreatic Ductal Adenocarcinoma: Multimodal Spatial Analysis and Prognosis

open access: yesCancer Science, EarlyView.
Using integrated spatial pathomics and transcriptomics, we show that neoadjuvant therapy (NAT) in pancreatic ductal adenocarcinoma (PDAC) induces substantial tumor microenvironment remodeling that is not captured by tumor regression grading (TRG) alone.

Yersinia enterocolitica serum resistance proteins YadA and ail bind the complement regulator C4b-binding protein. [PDF]

open access: yesPLoS Pathogens, 2008
Many pathogens are equipped with factors providing resistance against the bactericidal action of complement. Yersinia enterocolitica, a Gram-negative enteric pathogen with invasive properties, efficiently resists the deleterious action of human ...

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

open access: yesImmunology, 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‐

Inflammatory and Immunological Basis of Periodontal Diseases

open access: yesJournal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.
