Focus on Sarcoidosis
- Sarcoidosis is a systemic granulomatous disease with a variable clinical presentation and disease course. There is still no reliable biomarker available, which assists in the diagnosis or prediction of the clinical course. According to a murine model, the expression level of the metabolic checkpoint kinase mechanistic target of Rapamycin complex 1 (mTORC1) in granulomas of sarcoidosis patients may be used as a clinical biomarker.
- S100B is a calcium-binding protein found primarily in glial cells. In the setting of neuronal injury and disruption of the blood brain barrier, S100B can leak into the cerebrospinal fluid and systemic circulation.
