Modulation of human lymphocyte function by C3a and C3a(70-77). [PDF]

open access: yesThe Journal of experimental medicine, 1982
Human C3a and the synthetic octapeptide C3a (70-77), which retains the activities of an anaphylatoxin, inhibit in a concentration-dependent manner the generation of leukocyte inhibitory factor (LIF) activity by human mononuclear leukocytes and T lymphocytes cultured with the mitogens phytohemagglutinin (PHA) or concanavalin A (Con A) or the antigen ...

Complement C3a and C5a receptor blockade modulates regulatory T cell conversion in head and neck cancer

open access: yesJournal for ImmunoTherapy of Cancer, 2021
Background Resistance to therapy is a major problem in treating head and neck squamous cell carcinomas (HNSCC). Complement system inhibition has been shown to reduce tumor growth, metastasis, and therapeutic resistance in other tumor models, but has yet ...

Brief report on the relation between complement C3a and anti dsDNA antibody in systemic lupus erythematosus

open access: yesScientific Reports, 2022
Systemic lupus erythematosus (SLE) is a complex autoimmune disease characterized by the production of a diverse array of autoantibodies and the dysfunctional activation of the complement system.

Re-mineralization potential, shear bond strength and hydration characteristics of experimentally prepared tri-calcium aluminate phase-modified glass ionomer cement on sound and caries-affected dentin (An in vitro/in vivo study)

open access: yesBulletin of the National Research Centre, 2021
Background This study aimed to in vivo and in vitro evaluate the remineralization potential and shear bond strength (SBS) of experimentally prepared tri-calcium aluminate (C3A)-modified glass ionomer cements on sound and artificial caries-affected dentin

Antifungal activity of C3a and C3a-derived peptides against Candida

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2007
Antimicrobial peptides are generated during activation of the complement system [Nordahl et al. Proc. Natl. Acad. Sci. U. S. A. 2004, 101:16879-16884]. Here we show that the anaphylatoxin C3a exerts antimicrobial effects against the yeast Candida. Fluorescence microscopy and electron microscopy analysis demonstrated that C3a-derived peptides bound to ...

Species-specific differences in regulation of macrophage inflammation by the C3a–C3a receptor axis [PDF]

open access: yesInnate Immunity, 2018
Complement is an important arm of the innate immune system. Recent studies have shown that products of complement pathway activation can interact directly with other innate immune signaling molecules, including TLRs and inflammasome family members, during some infectious and chronic inflammatory disorders.

C3a receptor blockade protects podocytes from injury in diabetic nephropathy.

open access: yesJCI Insight, 2020
Renal activation of the complement system has been described in patients with diabetic nephropathy (DN), although its pathological relevance is still ill-defined.

Complement inhibition promotes endogenous neurogenesis and sustained anti-inflammatory neuroprotection following reperfused stroke. [PDF]

open access: yesPLoS ONE, 2012
The restoration of blood-flow following cerebral ischemia incites a series of deleterious cascades that exacerbate neuronal injury. Pharmacologic inhibition of the C3a-receptor ameliorates cerebral injury by attenuating post-ischemic inflammation. Recent

Influence of Lithium Carbonate on C3A Hydration

open access: yesAdvances in Materials Science and Engineering, 2018
Lithium salts, known to ameliorate the effects of alkali-silica reaction, can make significant effects on cement setting. However, the mechanism of effects on cement hydration, especially the hydration of C3A which is critical for initial setting time of

Complement C3a activates osteoclasts by regulating the PI3K/PDK1/SGK3 pathway in patients with multiple myeloma

open access: yesCancer Biology & Medicine, 2021
Objective: Myeloma bone disease (MBD) is the most common complication of multiple myeloma (MM). Our previous study showed that the serum levels of C3/C4 in MM patients were significantly positively correlated with the severity of bone disease.
