Complement, C1q, and C1q-related molecules regulate macrophage polarization

Frontiers in Immunology, 2014
Complement is a critical system of enzymes, regulatory proteins and receptors that regulates both innate and adaptive immune responses. Natural mutations in complement molecules highlight their requirement in regulation of a variety of human conditions ...

Acute anaphylactic and multiorgan inflammatory effects of Comirnaty in pigs: evidence of spike protein mRNA transfection and paralleling inflammatory cytokine upregulation

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Rare but severe adverse events (AEs) associated with mRNA‐lipid nanoparticle (LNP) COVID‐19 vaccines, such as Comirnaty, include anaphylaxis and inflammatory organ disorders, but their underlying mechanisms are poorly understood. We aimed to develop an animal model to study these phenomena.

A serine protease isolated from the bristles of the Amazonic caterpillar, Premolis semirufa, is a potent complement system activator. [PDF]

PLoS ONE, 2015
The caterpillar of the moth Premolis semirufa, commonly named pararama, is found in the Brazilian Amazon region. Accidental contact with the caterpillar bristles causes an intense itching sensation, followed by symptoms of an acute inflammation, which ...

Inflammatory and Immunological Basis of Periodontal Diseases

Journal 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.

Complement anaphylatoxins C3a and C5a induce a failing regenerative program in cardiac resident cells. Evidence of a role for cardiac resident stem cells other than cardiomyocyte renewal

SpringerPlus, 2012
Cardiac healing, which follows myocardial infarction, is a complex process guided by intricate interactions among different components. Some resident cell populations with a potential role in cardiac healing have already been described in cardiac tissues.

Impact of systemic diseases on periodontal remodeling: Mechanisms, mediators, and clinical relevance

Periodontology 2000, EarlyView.
Abstract Background Periodontal remodeling is a continuous, adaptive process essential for maintaining the structural and functional integrity of periodontal tissues. While external factors such as bacterial biofilm, excessive forces, and poor oral hygiene are recognized triggers of periodontal pathologies, they do not fully explain their persistent ...

Systemic impact of intramuscular snake envenomation and intravenous immunoglobulin‐based antivenom treatment on murine plasma proteome and peptidome

Protein Science, Volume 35, Issue 9, September 2026.
Abstract Snake envenomation remains a critical global public health challenge. In Brazil, the genus Bothrops is responsible for most accidents, typically resulting in coagulopathy, hemorrhage, and renal failure. Despite its clinical prevalence, the molecular mechanisms driving plasma protein disturbances remain poorly understood.

Thromboinflammatory biomarkers in obstetric pathophysiology: Predictive insights into placental insufficiency and feto‐maternal adverse outcomes

Clinical and Translational Discovery, Volume 6, Issue 4, August 2026.
Placental insufficiency is a thromboinflammatory disorder driven by angiogenic imbalance, complement activation, endothelial dysfunction and coagulation dysregulation, leading to microvascular thrombosis, impaired uteroplacental perfusion and adverse maternal and fetal outcomes, including pre‐eclampsia, fetal growth restriction and stillbirth.

Chemotactic response to human C3a and C5a anaphylatoxins. I. Evaluation of C3a and C5a leukotaxis in vitro and under stimulated in vivo conditions.

Journal of Immunology, 1978
Peptides C3a and C5a, also known as anaphylatoxins, are derived from C components C3 and C5 and have previously been reported to exhibit chemotactic activity.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

Advanced Healthcare Materials, Volume 15, Issue 27, 17 July 2026.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.
