An extracorporeal blood-cleansing device for sepsis therapy
网页2014年9月14日 · To efficiently remove magnetically opsonized pathogens and endotoxins from septic blood flowing at liters per hour without loss or dilution of blood, we developed a fluidic device design inspired...

Opsonin - Wikipedia
网页Opsonins help clear pathogens, as well as dead, dying and diseased cells. [2] Opsonins were discovered and named "opsonins" in 1904 by Wright and Douglas, who found that incubating bacteria with blood plasma enabled phagocytes to phagocytose (and thereby destroy) the bacteria.
Antibody opsonization - Wikipedia
网页Antibody opsonization is a process by which a pathogen is marked for phagocytosis through coating of a target cell with antibodies. Immunoglobulins participate in molecular tagging of pathogens which display antigens recognised by their specific paratope.
Opsonization: Process, Purpose, Effects & Examples - Cleveland …
网页2024年4月26日 · Opsonization is a process that helps your immune system identify and destroy old cells or germs (pathogens). Opsonins coat cells or pathogens so cells of your immune system (phagocytes) can find them, attach to them, swallow them and break them apart. Antibodies and complement proteins are common opsonins.
Physiology, Opsonization - StatPearls - NCBI Bookshelf
网页2023年5月1日 · Opsonization is an immune process which uses opsonins to tag foreign pathogens for elimination by phagocytes. Without an opsonin, such as an antibody, the negatively-charged cell walls of the pathogen and phagocyte repel each other. The pathogen can then avoid destruction and continue to replicate inside the human body.
Opsonins: Their function, identity, and clinical significance
网页The function of opsonins is to react with bacteria and make them more susceptible to ingestion by phagocytes. Opsonization of bacteria may occur by three different mechanisms. First, specific antibody alone may act as an opsonin. Specific antibody may also act as an opsonin in concert with complement, by activating C3 via the classic pathway of ...
[13] Opsonins and dysopsonins: An overview - ScienceDirect
网页1986年1月1日 · The prerequisite for such ingestion and subsequent digestion is the formation of the critical adhesive bond between the particle to be ingested and the phagocytic cell. Several biological entities are known to either promote (opsonins) or retard (dysopsonins) this event.
Opsonization - SpringerLink
网页Opsonin is a term introduced by Wright and Douglas (1903) to designate a factor (or factors) in serum that interacts with particles in a manner that renders the particles more readily ingested by phagocytic cells. In this chapter, we will consider the mechanisms by which opsonins interact with the particles they coat and with the phagocytic ...
13.2A: Opsonization - Biology LibreTexts
网页2023年8月31日 · Briefly describe two different ways bacteria may resist opsonization. Opsonization, or enhanced attachment, refers to the antibody molecules IgG and IgE, the complement proteins C3b and C4b, and other opsonins attaching antigens to phagocytes. This results in a much more efficient phagocytosis.
