Helix 8 in chemotactic receptors of the complement system.

open access: yesPLoS Computational Biology, 2022
Host response to infection involves the activation of the complement system leading to the production of anaphylatoxins C3a and C5a. Complement factor C5a exerts its effect through the activation of C5aR1, chemotactic receptor 1, and triggers the G ...

Amyloid-β1-42 oligomers enhance mGlu5R-dependent synaptic weakening via NMDAR activation and complement C5aR1 signaling

open access: yesiScience, 2023
Summary: Synaptic weakening and loss are well-correlated with the pathology of Alzheimer’s disease (AD). Oligomeric amyloid beta (oAβ) is considered a major synaptotoxic trigger for AD.

RECEPTORS FOR COMPLEMENT ON LEUKOCYTES [PDF]

open access: yesThe Journal of Experimental Medicine, 1968
Sheep red blood cells sensitized by 7S, but not by 19S rabbit anti-Forssman antibodies, adhere and form rosettes on mouse macrophages and on a few monocytes and polymorphonuclear cells (PMN). When, however, C' factors from mouse serum are added to the antigen-19S antibody complex (EAC'), rosettes are formed on most mouse peritoneal macrophages and PMN ...

Receptor-Mediated NETosis on Neutrophils

open access: yesFrontiers in Immunology, 2021
Neutrophil extracellular traps (NETs), a web-like structures containing chromatin, have a significant role in assisting the capture and killing of microorganisms by neutrophils during infection.

The many roles of C1q

open access: yeseLife, 2020
The ability of a well-known component of the complement cascade to bind to a variety of receptors has implications for signaling biology, spinal cord injury and, possibly, the evolution of the complement system.

Innate and adaptive AAV-mediated immune responses in a mouse model of Duchenne muscular dystrophy

open access: yesMolecular Therapy: Methods & Clinical Development, 2023
High systemic doses of adeno-associated viruses (AAVs) have been associated with immune-related serious adverse events (SAEs). Although AAV was well tolerated in preclinical models, SAEs were observed in clinical trials, indicating the need for improved ...

Properdin Modulates Complement Component Production in Stressed Human Primary Retinal Pigment Epithelium Cells

open access: yesAntioxidants, 2020
The retinal pigment epithelium (RPE) maintains visual function and preserves structural integrity of the retina. Chronic dysfunction of the RPE is associated with retinal degeneration, including age-related macular degeneration (AMD).

Relative Impact of Complement Receptors CD21/35 (Cr2/1) on Scrapie Pathogenesis in Mice

open access: yesmSphere, 2017
Complement receptors 1 and 2 (CR1/2 or CD35/CD21) recognize complement-opsonized antigens to initiate innate and adaptive immunity, respectively. CD35 stimulates phagocytosis on macrophages and antigen presentation on follicular dendritic cells (FDCs ...

Complement System: An Immunotherapy Target in Colorectal Cancer

open access: yesFrontiers in Immunology, 2022
Colorectal cancer (CRC) is the third most common malignant tumor and the second most fatal cancer worldwide. Several parts of the immune system contribute to fighting cancer including the innate complement system.

Complement peptide receptors in GtoPdb v.2021.3 [PDF]

open access: yes, 2021
Complement peptide receptors (nomenclature as agreed by the NC-IUPHAR subcommittee on Complement peptide receptors [107]) are activated by the endogenous ~75 amino-acid anaphylatoxin polypeptides C3a and C5a, generated upon stimulation of the complement ...
