Elevated Expression of the Cerebrospinal Fluid Disease Markers Chromogranin A and Clusterin in Astrocytes of Multiple Sclerosis White Matter Lesions.

Using proteomics, we previously identified chromogranin A (CgA) and clusterin (CLU) as disease-related proteins in the cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS). CgA and CLU are involved in cell survival and are implicated in neurodegenerative disorders and may also have roles in MS pathophysiology. We investigated CgA and CLU expression in lesions and nonlesional regions in postmortem brains of MS patients and controls and in the brains of marmosets with experimental autoimmune encephalomyelitis.

Decreased systemic IL-7 and soluble IL-7Rα in multiple sclerosis patients.

Polymorphisms (single-nucleotide polymorphism (SNP)) in the interleukin-7 receptor-α (IL-7Rα)/IL-7 pathway are associated with an increased risk to develop multiple sclerosis (MS). The rs6897932 SNP in the IL-7Rα leads to increased soluble IL-7Rα production. Given the functional interaction between sIL-7Rα, membrane-bound IL-7Rα and IL-7, we assessed IL-7, mIL-7Rα and sIL-7Rα levels in MS patients and healthy controls (HCs).

The IL-7Rα pathway is quantitatively and functionally altered in CD8 T cells in multiple sclerosis.

The IL-7Rα single nucleotide polymorphism rs6897932 is associated with an increased risk for multiple sclerosis (MS). IL-7Rα is a promising candidate to be involved in autoimmunity, because it regulates T cell homeostasis, proliferation, and antiapoptotic signaling. However, the exact underlying mechanisms in the pathogenesis of MS are poorly understood.

The monocyte transcriptome during pregnancy in multiple sclerosis: prominent expression of the Fc-receptor CD64.

Background: During the third trimester of pregnancy multiple sclerosis (MS) disease activity is reduced. It is not fully understood which factors mediate this disease amelioration.

Objective: To study alterations of the monocyte transcriptome during pregnancy in MS patients, using a genomewide approach to identify differentially regulated genes.
