Definition and Biochemistry
Procalcitonin is a 116-amino-acid protein originally synthesized in the C cells of the thyroid gland. While its primary function revolves around calcium homeostasis through the regulation of calcitonin, notably, procalcitonin serves as an acute-phase reactant. In times of inflammation or infection, various cells throughout the body, particularly immune cells, start to produce procalcitonin. This response can be triggered by lipopolysaccharides and cytokines, reflecting its direct connection between immune response and infection processes. Studies have shown that elevated levels of procalcitonin correlate with severe infections, making it a significant biomarker in clinical practice.
Synthesis and Regulation
The synthesis of procalcitonin is regulated through a variety of mechanisms that reflect the body’s status in terms of infection. The process begins with the transcription of the CALC1 gene located on chromosome 11, leading to the translation of pre-procalcitonin. Once this stage is completed, procalcitonin can be cleaved into its active form or be released into the circulation. Factors such as bacterial endotoxins and inflammatory cytokines, including interleukin-6 and tumor necrosis factor-alpha, greatly influence this synthesis. This ability to produce procalcitonin rapidly during systemic inflammation is particularly important for clinicians aiming to assess bacterial versus viral infections.
Pathophysiological Significance
The pathophysiological implications of procalcitonin extend beyond simple markers of infection.
