Enhancement of platelet response to immune complexes and IgG aggregates by lipid A-rich bacterial lipopolysaccharides. [PDF]
The effect of the common lipid moiety of bacterial LPS on secretion from washed human platelets has been studied. The lipid A-rich LPS of S. minnesota R595 and a lipid A preparation both potentiated platelet serotonin secretion in response to IgG ...

Rapid redistribution of clathrin onto macrophage plasma membranes in response to Fc receptor-ligand interaction during frustrated phagocytosis. [PDF]
We have observed increases in assembled clathrin on the plasma membrane during "frustrated phagocytosis," the spreading of macrophages on immobilized immune complexes. Resident macrophages freshly harvested from the peritoneal cavity of mice and attached

Human immunoglobulin A (IgA), comprising the isotypes IgA1 and IgA2, protects ~400 m2 of mucosal surfaces against microbial infections but can also lead to aberrant IgA deposits that cause disease. Certain bacteria have evolved peptidases that cleave the

The binding affinity of human IgG for its high affinity Fc receptor is determined by multiple amino acids in the CH2 domain and is modulated by the hinge region. [PDF]
A family of chimeric immunoglobulins (Igs) bearing the murine variable region directed against the hapten dansyl linked to human IgG1, -2, -3, and -4 has been characterized with respect to binding to the human high affinity Fc gamma receptor, Fc gamma RI.

Ampk regulates IgD expression but not energy stress with B cell activation. [PDF]
Ampk is an energy gatekeeper that responds to decreases in ATP by inhibiting energy-consuming anabolic processes and promoting energy-generating catabolic processes.

Structural characterisation of human immunoglobulin G Fc fragment and its interaction with heparin [PDF]
Human immunoglobulin (Ig) G is the most commonly found class of antibody in the human body and is involved in pathogen recognition as a part of the adaptive and innate immune response. Recognition occurs through the fragment antibody binding (FAB) region and interaction with the innate immune system occurs via interactions between the fragment ...
