Regulatory effects of C5a on IL-17A, IL-17F, and IL-23

Frontiers in Immunology, 2013
The complement anaphylatoxin, C5a, through binding to its receptors (C5aR or C5L2), has important biological properties for recruitment and activation of phagocytes.

The role of the host—Neutrophil biology

Periodontology 2000, EarlyView., 2023
Abstract Neutrophilic polymorphonuclear leukocytes (neutrophils) are myeloid cells packed with lysosomal granules (hence also called granulocytes) that contain a formidable antimicrobial arsenal. They are terminally differentiated cells that play a critical role in acute and chronic inflammation, as well as in the resolution of inflammation and wound ...

Macrophages self-generate and refine chemotactic gradients during migration towards complement C5a.

PLoS Biology
Macrophages rely on efficient chemotaxis to locate sites of infection and tissue damage. One general strategy that enhances chemotactic accuracy is the use of self-generated gradients, where cells locally deplete attractants to create or sharpen guidance

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

The involvement of C5a in the progression of experimental arthritis with Porphyromonas gingivalis infection in SKG mice

Arthritis Research & Therapy, 2018
Background Epidemiological evidence to suggest that periodontal disease (PD) is involved in the progression of rheumatoid arthritis (RA) is increasing. The complement system plays a critical role in immune responses.

Inhibiting the C5-C5a receptor axis

, 2011
Activation of the complement system is a major pathogenic event that drives various inflammatory responses in numerous diseases. All pathways of complement activation lead to cleavage of the C5 molecule generating the anaphylatoxin C5a and, C5b that ...

Cross‐protective effect of a multicomponent fusion protein vaccine during a natural episode of Streptococcus zooepidemicus respiratory disease in ponies

Equine Veterinary Journal, EarlyView.
Abstract Background Streptococcus equi subspecies zooepidemicus is a highly diverse opportunistic pathogen of horses, associated with respiratory disease and endometritis. Objectives To characterise S. zooepidemicus isolates recovered from young ponies during a natural episode of respiratory disease, and to determine if vaccination with Strangvac®, a ...

Unraveling the Plasma Extracellular Vesicles Proteome: Predictors of Resistance in Immunotherapy of Advanced Melanoma

International Journal of Cancer, EarlyView.
ABSTRACT Despite substantial clinical benefit from immune checkpoint inhibitors (ICI), advanced melanoma remains challenging due to frequent treatment resistance. Resistance may be intrinsic (primary) or emerge over time (secondary). Biomarkers predicting distinct resistance phenotypes before therapy are lacking.
