opsonin
This term is used exclusively within immunology and biochemistry to describe the molecular "tags" that prepare a pathogen for phagocytosis. It carries a highly technical register and is typically found in medical textbooks, peer-reviewed journals, or clinical discussions regarding the innate immune response.
Because it refers to a specific class of biological molecules, it is used in a precise scientific context to distinguish between the agent that marks the target (the opsonin) and the process of marking (opsonization). It is not used in general conversation or metaphorical contexts.
Meanings
Examples
The antibody acts as an opsonin to facilitate the phagocytosis of the bacteria.
The antibody acts as an opsonin to facilitate the phagocytosis of the bacteria.
C3b is a potent opsonin that marks pathogens for destruction.
C3b is a potent opsonin that marks pathogens for destruction.
Does this specific protein function as an opsonin in the innate immune response?
Without a proper opsonin, the macrophage might struggle to recognize the intruder.
I need to remember that an opsonin essentially tags the target for the immune system.
The binding of an opsonin to the cell wall increases the efficiency of engulfment.
The binding of an opsonin to the cell wall increases the efficiency of engulfment.
Certain pathogens have evolved mechanisms to avoid being coated by any opsonin.
Let us examine how the opsonin interacts with the Fc receptor on the leukocyte.
