PURPOSE Flail chest (FC) injuries represent a significant burden on trauma services because of its high morbidity and mortality. Current gold standard conservative management strategies for FC, are now being challenged by renewed interest in surgical rib fixation. This retrospective epidemiological study sets out to evaluate FC patients, and quantify the natural history of this injury by studyi...
We constructed chimeric receptors to dissect the role of the transmembrane (TM) domain in cell surface expression of and phagocytosis by the chain–dependent Fc receptors Fc RIIIA and Fc RI. Fc R chimeras containing the TM and cytoplasmic (CY) domains of the chain were expressed on the cell surface and mediated an efficient phagocytic signal. In contrast, chimeras containing the Fc RIIIA TM were...
The binding sites on human IgG1 for human Fc gamma receptor (Fc gamma R) I, Fc gamma RIIa, Fc gamma RIIb, Fc gamma RIIIa and neonatal FcR have been mapped. A common set of IgG1 residues is involved in binding to all Fc gamma Rs, while Fc gamma RII and Fc gamma RIII utilize distinct sites outside this common set. In addition to residues which abrogated binding to the Fc gamma R, several position...
BACKGROUND Despite poor evidence and high costs, fibrinogen concentrate (FC) represents one of the most frequently used hemostatic agents in exsanguinating trauma. The aim was to assess whether the administration of FC in severely injured patients was associated with improved outcomes. METHODS Patients documented in the Trauma Registry of the German Society for Trauma Surgery (primary admissi...
Fc receptors (Fc R) trigger inflammatory reactions in response to immunoglobulinopsonized pathogens and antigen-antibody complexes. The coordinate expression of activating and inhibitory Fc R ensures the homeostasis of immune complex-driven inflammatory responses. In this study, we used antibodies with preferential binding for activating Fc RIIa and inhibitory Fc RIIb receptors to investigate t...
