Opsonization occurs when antibodies or complement proteins bind to pathogens, such as bacteria, making them more recognizable to phagocytic cells like macrophages and neutrophils. This facilitates the process of phagocytosis, where the pathogen is engulfed and destroyed by the immune cells.

The process of coating bacteria with serum protein attachment of phagocytes is called?

in some instances, adherence occurs easily, and the microorganism is readily phagocytized. Microorganisms can be more readily phagocytized if they are first coated with certain serum proteins that promote attachment of the microorganisms to the phagocyte. this process is called opsonization.


Ag - Ab binding may result in?

The binding of antigen and antibody may result in the formation of immune complexes, which can activate complement system leading to inflammation and tissue damage. Additionally, it can also lead to neutralization or opsonization of the antigen, facilitating its clearance by immune cells.


What are the five different types of Igs and functions?

The five different types of immunoglobulins (Igs) are IgG, IgA, IgM, IgD, and IgE. Their functions include neutralization of pathogens, opsonization for phagocytosis, activation of complement system, mucosal immunity, and mediation of allergic responses.


Why IGM is so much efficient in activating complement than IgG?

IgM is more efficient in activating complement than IgG because of its larger size and pentameric structure, which allows for more binding sites and better clustering of complement proteins. This leads to a more robust activation of the complement cascade and increased inflammation and opsonization.


Important effector function of antibody molecules is?

The important effector functions of antibody molecules include opsonization, where antibodies mark pathogens for destruction by immune cells, neutralization, where antibodies block the ability of pathogens to infect host cells, and complement activation, where antibodies trigger a cascade of proteins to help destroy pathogens.

Related Questions

How is opsonization associated with inflammation?

In the immune system, opsonization occurs and causes swelling, redness, production at the site of the infection and pain and discomfort.


What is the difference between opsonization and neutralization?

Opsonization involves an antibody binding to a pathogen itself while neutralizing invovles an antibody binding to a toxin, AKA something the pathogen produces.


What is the function of the complement cascade called opsonization?

Opsonization is a process in which pathogens are marked for destruction by phagocytic cells. It involves the binding of complement proteins to the surface of the pathogen, making it easier for phagocytes to recognize and engulf the pathogen.


What is it called when some of the chemicals released during complement fixation enhance phagocytosis?

Opsonization Chemotaxis


How does the process of opsonization involve the enhancement of phagocytosis by immune cells?

Opsonization is a process where immune cells mark pathogens with molecules called opsonins, making them easier for phagocytes to recognize and engulf. This enhances phagocytosis by promoting the binding of the pathogen to the phagocyte's receptors, leading to its ingestion and destruction.

What is opsonisation?

Enhances phagocytes by coating a microbe. Opsonization promotes attachment of a phagocyte to a microbe.


Which of the following is an effect of complement activation?

Complement activation can lead to direct killing of pathogens by forming pores in their cell membranes, promoting inflammation by recruiting immune cells to the site of infection, and facilitating clearance of immune complexes and cellular debris.


How do macrophages recognize infectious agents such as bacteria?

When antibodies bind to the epitopes of an antigen(bacteria) via antigen receptors, the antibodies present the bacteria to a macrophages in a form that they recognize the foreign substance and engulf them. This antibody-antigen "team work" is also known as opsonization
