Soluble cytokine receptors: their role in immunoregulation.
A number of cytokine receptors exist in soluble form in the biological fluids of both animals and humans, a phenomenon that might have immunoregulatory implications in vivo. Although these soluble receptors specifically inhibit binding and activity of their respective cytokines in vitro, their actual function in vivo as cytokine inhibitors or as carrier proteins is unclear. Abnormalities in the production of these substances might contribute to the pathophysiology of immune and neoplastic diseases. Besides their role in regulating cytokine activity in vivo, soluble cytokine receptors hold significant potential for therapeutic use as very specific anticytokine agents and as indicators in diagnosis and assessment of immune parameters, prognosis, disease progression, response to treatment, etc., in a variety of autoimmune and malignant diseases.
