The term "complement" was introduced by Paul Ehrlich in the late 1890s, as part of his larger theory of the immune system. (wikidoc.org)

If a person lacked the ability to form C5, what direct result of complement could still occur? (workflowdigital.com)

The immune system is a wonderful collaboration between cells and proteins that work together to provide defense against infection. (primaryimmune.org)
Instead, the immune system is dispersed throughout the body to provide rapid responses to infection. (primaryimmune.org)
S. iniae is not currently as- particular, vaccination programs at fi sh farms have reduced signed to any Lancefi eld group and is -hemolytic on blood the reservoir of infection for additional clinical cases. (cdc.gov)
Misidentifi cation of S. iniae infection pathogenic strains were more resistant to oxidative burst is likely to be the main reason for low levels of detection activity in macrophages ( 14 ). (cdc.gov)
Cryptococcosis is the most common fungal infection of the central nervous system and may present as a space-occupying lesion, meningitis, or meningoencephalitis. (medscape.com)
Although some results remain to be confirmed, low serum 25(OH)D levels have been linked to all-cause cardiovascular, cancer and infection-related mortality and also to stroke. (biomedcentral.com)
Ineffective clearance of SARS-CoV-2 infection in the aged respiratory system. (aging-us.com)

The accumulation of anaphylatoxins (such as C5a) from complement activation might also have a role. (medscape.com)

A number of previous publications have demonstrated the upregulation of TNF-α in a variety of contexts including bronchoalveolar lavage (BAL) fluid protein, macrophage protein secretion and macrophage TNF messenger ribonucleic acid content 9 - 16 . (ersjournals.com)

By 1894, several laboratories had demonstrated that serum from guinea pigs that had recovered from cholera killed the cholera bacterium in vitro. (wikipedia.org)
In vitro, bound complement is localized to infoldings of the parasite's tegument and not on its free surfaces [ 499 ]. (nanomedicine.com)

The development of all cells of the immune system begins in the bone marrow with a hematopoietic (blood-forming) stem cell (Figure 1:2). (primaryimmune.org)
Because of its ability to generate an entire immune system, this is the cell that is most important in bone marrow or hematopoietic stem cell transplantation . (primaryimmune.org)

With the aging population and significant improvement of living standards in China, the incidence of cerebrovascular diseases has increased at an average annual rate of 8.3 %, ranking first among the causes of death among Chinese residents and being the main cause of illness and death in patients with the nervous system[ 2 ].
