Interaction Between the Complement System and Infectious Agents – A Potential Mechanistic Link to Neurodegeneration and Dementia

open access: yesFrontiers in Cellular Neuroscience, 2021
As part of the innate immune system, complement plays a critical role in the elimination of pathogens and mobilization of cellular immune responses. In the central nervous system (CNS), many complement proteins are locally produced and regulate nervous ...

Complement activation and protein adsorption by carbon nanotubes [PDF]

open access: yes, 2006
As a first step to validate the use of carbon nanotubes as novel vaccine or drug delivery devices, their interaction with a part of the human immune system, complement, has been explored.

The tumour microenvironment links complement system dysregulation and hypoxic signalling. [PDF]

open access: yes, 2018
The complement system is an innate immune pathway typically thought of as part of the first line of defence against "non-self" species. In the context of cancer, complement has been described to have an active role in facilitating cancer-associated ...

INTERACTIONS OF C-REACTIVE PROTEIN WITH THE COMPLEMENT SYSTEM [PDF]

open access: yesThe Journal of Experimental Medicine, 1974
Protamine sulfate was found to consume large amounts of C selectively during preincubation with sera of individuals in the "acute phase". Marked depletion of C1, C4, and C2 with minimal, if any, depletion of C3-9, was observed. The consumption was time and temperature dependent, occurring most rapidly and extensively at 37°C, 0.10 M relative salt ...

Innate immune system activation in zebrafish and cellular models of Diamond Blackfan Anemia. [PDF]

open access: yes, 2018
Deficiency of ribosomal proteins (RPs) leads to Diamond Blackfan Anemia (DBA) associated with anemia, congenital defects, and cancer. While p53 activation is responsible for many features of DBA, the role of immune system is less defined.

Complement Evasion: An Effective Strategy That Parasites Utilize to Survive in the Host

open access: yesFrontiers in Microbiology, 2019
Parasitic infections induce host immune responses that eliminate the invading parasites. However, parasites have evolved to develop many strategies to evade host immune attacks and survive in a hostile environment. The complement system acts as the first

Preferential association of hepatitis C virus with CD19+ B cells is mediated by complement system [PDF]

open access: yes, 2016
Extrahepatic disease manifestations are common in chronic hepatitis C virus (HCV) infection. The mechanism of HCV-related lymphoproliferative disorders is not fully understood.
