C5a, but not C5a-des Arg, induces upregulation of heteromer formation between complement C5a receptors C5aR and C5L2

, 2013
Receptors for C5a have an important role in innate immunity and inflammation where their expression and activation is tightly regulated. There are two known receptors for C5a: the C5a receptor (C5aR) and the C5a receptor like-2 (C5L2) receptor.

CD177-mediated nanoparticle targeting of human and mouse neutrophils. [PDF]

PLoS ONE, 2018
Neutrophils are the most abundant white blood cells, with a vital role in innate immune defense against bacterial and fungal pathogens. Although mostly associated with pathological processes directly related to immune defense, they can also play a ...

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.

C5a/C5aR1 Pathway Is Critical for the Pathogenesis of Psoriasis

Frontiers in Immunology, 2019
Psoriasis is one of the most common chronic inflammatory skin diseases, affecting ~2% of the population. The lack of characterization of the pathogenesis of psoriasis has hindered efficient clinical treatment of the disease.

Modulation of C5a–C5aR1 signaling alters the dynamics of AD progression

Journal of Neuroinflammation, 2022
Background The complement system is part of the innate immune system that clears pathogens and cellular debris. In the healthy brain, complement influences neurodevelopment and neurogenesis, synaptic pruning, clearance of neuronal blebs, recruitment of ...

Advances in Immunological Combination Therapy for Colorectal Cancer

iMetaMed, EarlyView.
Review the progress of combined immunotherapy for colorectal cancer. ABSTRACT Immune checkpoint inhibitors (ICIs) have been utilized extensively and shown to be therapeutically beneficial in the treatment of solid tumors in recent years. Nonetheless, considerable heterogeneity in Colorectal cancer (CRC) requires careful consideration.

The Endothelial CXCR Family in Vascular Health and Disease

iNew Medicine, EarlyView.
ABSTRACT Endothelial cells (ECs) form the dynamic interface between blood and tissue, serving as key regulators of vascular homeostasis, inflammation, and repair. Among the molecular systems governing endothelial behavior, the C‐X‐C motif chemokine receptor (CXCR) family—originally characterized in immunology for its roles in leukocyte trafficking and ...

The C5a chemoattractant receptor mediates mucosal defence to infection

, 1996
A family of G-protein-coupled chemoattractant receptors is known to mediate the transport and activation of neutrophils and macrophages. This family includes receptors for chemokines, such as interleukin-8, bacterial formylated peptides, platelet ...

New developments in C5a receptor signaling

Cell Health and Cytoskeleton, 2012
Complement activation usually results in the formation of complement fragment 5a (C5a) that interacts with its two receptors, C5aR and C5L2. These receptors belong to the rhodopsin family of G protein-coupled seven transmembrane-containing receptors. C5aR and C5L2 are expressed on/in a wide variety of cells and tissues.
