Alternative Pathway Evaluation [PDF]

open access: possibleCurrent Protocols in Immunology, 1994
AbstractThe alternative pathway of complement shares its terminal components (C3 and C5 through 9) with the classical pathway, but has several unique components, including factors D, B, and P (properdin). This unit presents methods for assaying total alternative pathway activity and the activity of factors B and D. Radial immunodiffusion (RID) can also

The alternative antigen pathway

Immunology Today, 1989
In this article, John Tew, Marie Kosco and Andras Szakal describe progress in deciphering a novel antigen pathway that represents an alternative to classical clearance by phagocytes. Upon booster immunization, immune complexes form rapidly and these complexes are handled not only by phagocytes but also by a series of non-phagocytic cells in a distinct ...

Alternative Complement Pathway in Schizophrenia [PDF]

open access: possibleNeurochemical Research, 2010
In the present study, we evaluated functional activity of the alternative pathway of complement in schizophrenia by measuring the alternative pathway hemolytic activity (AH50) of complement as well as hemolytic activity of the complement C3 component (C3H50) in the blood of patients with schizophrenia and healthy subjects.

An ‘Alternative’ Pathway of T Cell Activation [PDF]

open access: possibleInternational Archives of Allergy and Immunology, 1994
T cell receptor mediated signals in T cell activation determine the specificity, while costimulatory/accessory signals are responsible for functional results of the immune response. Given the large number of accessory receptors in the T cell membrane, there exists a potent instrument to fine-tune immune reactions.

The complement alternative pathway and hemostasis

Immunological Reviews, 2022
SummaryThe complement and hemostatic systems are complex systems, and both involve enzymatic cascades, regulators, and cell components—platelets, endothelial cells, and immune cells. The two systems are ancestrally related and are defense mechanisms that limit infection by pathogens and halt bleeding at the site of vascular injury.

Alternative pathway amplification and infections

Immunological Reviews, 2022
SummaryThe alternative pathway (AP) is the phylogenetically oldest arm of the complement system and may have evolved to mark pathogens for elimination by phagocytes. Studies using purified AP proteins or AP‐specific serum showed that C3b amplification on bacteria commenced following a lag phase of about 5 min and was highly dependent on the ...

The Complement Alternative Pathway and Preeclampsia

Current Hypertension Reports, 2018
Significant and intricate immune adaptations are essential for the establishment and maintenance of normal pregnancy. Preeclampsia is a morbid, potentially life-threatening disease for both mother and neonate that occurs uniquely in pregnancy, at least in part, due to maternal immune maladaptation.

Seeking Alternative Pathways

Science, 2004
IMMUNOLOGY Cell-surface receptors in the signaling lymphocyte activation molecule (SLAM) family play diverse roles in the lives of T and B lymphocytes, NK cells, dendritic cells, and macrophages.

The Alternative Pathway of Complement Activation

1976
Publisher Summary This chapter presents the alternative pathway of complement activation. Two pathways for the recruitment of complement and its biological activities exist in plasma and serum. The first is termed as the “classical pathway,” which is triggered by contact of C1 with immune complexes containing antibodies of the immunoglobulin G (IgG ...

Alternative p38 MAPK Pathways

2007
There are four members of the mammalian p38 mitogen-activated protein kinases (MAPKs) family (p38α, p38β, p38γ, and p38δ) which are about 60% identical in their amino acid sequence but differ in their expression patterns, substrate specificities, and sensitivities to chemical inhibitors such as SB203580.
