Comprehensive analysis of microRNA profiles in multiple sclerosis including next-generation sequencing.

Background: MicroRNAs (miRNAs) are short, noncoding RNAs with gene regulatory functions whose expression profiles may serve as disease biomarkers.

Objective: The objective of this study was to perform a comprehensive analysis of miRNA expression profiles in blood of patients with a clinically isolated syndrome (CIS) or relapsing-remitting multiple sclerosis (RRMS) including next-generation sequencing (NGS).

Methods: miRNA expression was analyzed in whole blood samples from treatment-naïve patients with CIS (n = 25) or RRMS (n = 25) and 50 healthy controls by NGS, microarray analysis, and quantitative real-time polymerase chain reaction (qRT-PCR).

Quantifying the relationship between temperature regulation in the ear and floret development stage in wheat (Triticum aestivum L.) under heat and drought stress.

Thermal imaging is a valuable tool for the clarification of gas exchange dynamics between a plant and its environment. The presence of stomata in wheat (Triticum aestivum L.) glumes and awns offers an opportunity to assess the photosynthetic activity of ears up to and during flowering.

GABAB receptor antibodies in paraneoplastic cerebellar ataxia.

Autoantibodies to the gamma-aminobutyric acid-B (GABAB) receptor were recently described in patients with limbic encephalitis presenting with early or prominent seizures. We report on a 64-year-old man with malignant melanoma who during adjuvant therapy with interferon (IFN)-alpha developed cerebellar ataxia. Indirect immunofluorescence on brain tissue sections revealed high-titer (1:20,000) IgG1 serum autoantibodies to the cerebellar molecular and granular layer, which were confirmed to be directed against GABAB receptor in a cell-based assay.

Interferon-beta increases BAFF levels in multiple sclerosis: implications for B cell autoimmunity.

B cells are increasingly recognized as major players in multiple sclerosis pathogenesis. The BAFF/APRIL system is crucial for B cell homoeostasis and may drive B cell-dependent autoimmunity. We asked whether this system is affected by Interferon (IFN)-beta therapy.

CCL19 is constitutively expressed in the CNS, up-regulated in neuroinflammation, active and also inactive multiple sclerosis lesions.

CCL19 and CCL21 bind to CCR7, which is crucial for both inducing an immune response and establishing immunological tolerance. We report that in the normal human brain CCL19, but not CCL21, is transcribed, and detectable as a protein in tissue lysates and in cerebrospinal fluid. In both active and inactive multiple sclerosis (MS) lesions CCL19 transcripts were elevated.
