Microglial activation arises after aggregation of phosphorylated-tau in a neuron-specific P301S tauopathy mouse model [PDF]

open access: yes, 2020
Alzheimer's disease, progressive supranuclear palsy and frontotemporal dementia are characterized by neuronal expression of aberrant tau protein, tau hyperphosphorylation (pTAU), tau aggregation and neurofibrillary tangle formation sequentially ...

Complement is activated in progressive multiple sclerosis cortical grey matter lesions [PDF]

open access: yes, 2016
The symptoms of multiple sclerosis (MS) are caused by damage to myelin and nerve cells in the brain and spinal cord. Inflammation is tightly linked with neurodegeneration, and it is the accumulation of neurodegeneration that underlies increasing ...

Genome-scale CRISPR screening reveals that C3aR signaling is critical for rapid capture of fungi by macrophages.

open access: yesPLoS Pathogens, 2022
The fungal pathogen Histoplasma capsulatum (Hc) invades, replicates within, and destroys macrophages. To interrogate the molecular mechanisms underlying this interaction, we conducted a host-directed CRISPR-Cas9 screen and identified 361 genes that ...

Retinal Injury Activates Complement Expression in Müller Cells Leading to Neuroinflammation and Photoreceptor Cell Death

open access: yesCells, 2023
Retinal detachment (RD) is a neurodegenerative blinding disease caused by plethora of clinical conditions. RD is characterized by the physical separation of retina from the underlying retinal pigment epithelium (RPE), eventually leading to photoreceptor ...

Comparative analysis of the acute response of the trout, O. mykiss, head kidney to in vivo challenge with virulent and attenuated infectious hematopoietic necrosis virus and LPS-induced inflammation [PDF]

open access: yes, 2008
Background: The response of the trout, O. mykiss, head kidney to bacterial lipopolysaccharide (LPS) or active and attenuated infectious hematopoietic necrosis virus (IHNV and attINHV respectively) intraperitoneal challenge, 24 and 72 hours post-injection,

Research progress on the role of inflammatory mediators in the pathogenesis of epilepsy

open access: yesIbrain, Volume 11, Issue 1, Page 44-58, Spring 2025.
In the central nervous system, activated immune cells lead to the overproduction of inflammatory mediators through the corresponding signal pathway. Under the stimulation of inflammatory factors, neuroinflammation ultimately occurs. Overexpression of inflammatory mediators and activated immunocytes plays an important role in the emergence and ...

The complement cascade as a mediator of tissue growth and regeneration [PDF]

open access: yes, 2010
Recent evidence has demonstrated that the complement cascade is involved in a variety of physiologic and pathophysiologic processes in addition to its role as an immune effector.

Complement C3 mediates adolescent social isolation‐induced hippocampal synaptic deficits and sex‐specific emotional dysfunction

open access: yesInterdisciplinary Medicine, EarlyView.
Adolescent social isolation disrupts hippocampal function and exacerbates emotional symptoms, with sex‐specific patterns, as shown by human studies. In mice, social isolation decreased hippocampal synaptic density and calcium signaling, upregulated complement proteins, and activated complement‐mediated microglial synaptic phagocytosis.

Down-Regulation of C3aR/C5aR Inhibits Cell Proliferation and EMT in Hepatocellular Carcinoma

open access: yesTechnology in Cancer Research & Treatment, 2020
Complement 3a (C3a) and complement 5a (C5a), small cleavage fragments generated by complement activation, has been previously shown to be obviously up-regulated in highly metastatic hepatocellular carcinoma (HCC) cells. However, their functional roles in

Negative regulation of pulmonary Th17 responses by C3a anaphylatoxin during allergic inflammation in mice. [PDF]

open access: yesPLoS ONE, 2012
Activation of complement is one of the earliest immune responses to exogenous threats, resulting in various cleavage products including anaphylatoxin C3a.
