PROPERDIN Meaning and Definition

  1. Properdin is a protein molecule that plays a vital role in the immune system as a positive regulator of the alternative pathway of the complement system. The complement system is a series of proteins that work together to eliminate pathogens, promote inflammation, and enhance phagocytosis. The alternative pathway is one of the pathways through which the complement system can be activated.

    The function of properdin is to stabilize the C3 convertase enzyme, which is essential for the activation of the alternative pathway. It binds to C3b, a molecule produced during complement activation, and forms a complex that prevents inactivation and degradation of the C3 convertase. This stabilization allows for the continued production of C3b fragments, which can further amplify and sustain the complement response against pathogens.

    Properdin is produced by immune cells, such as neutrophils, monocytes, and macrophages, as well as by liver cells and adipose tissue. It is mainly found in the blood plasma, where it circulates in an inactive form until it is needed for complement activation.

    Dysregulation or deficiencies in properdin can lead to immune-related disorders, such as increased susceptibility to infections or autoimmune diseases. Researchers are studying properdin and its interactions with other complement proteins to gain insights into its role in health and disease, with the aim of developing targeted therapies for complement-related disorders.

Etymology of PROPERDIN

The word "Properdin" derives from the Latin term "pro" meaning "for" or "in favor of", and "perdere" meaning "to lose" or "to destroy". The term was coined by the German microbiologist and immunologist Heinz Fraenkel-Conrat in 1936 to describe a protein involved in the alternative pathway of the complement system, a part of the immune system. The prefix "pro-" indicates its function in favoring the activation and amplification of the complement system in response to an infection or other immune challenge.
