The first global landscape analysis of multiple sclerosis research funding.

Introduction: Multiple sclerosis (MS) is an immune-mediated central nervous system disorder and a growing global health challenge affecting nearly 3 million people worldwide. Incidence and prevalence continue to increase with no known cause or cure. Globally governments and non-profit organizations fund research toward better understanding of and treatments for multiple sclerosis.

Tongue-on-a-Chip: Parallel Recording of Sweet and Bitter Receptor Responses to Sequential Injections of Pure and Mixed Sweeteners.

A microfluidic tongue-on-a-chip platform has been evaluated relative to the known sensory properties of various sweeteners. Analogous metrics of typical sensory features reported by human panels such as sweet taste thresholds, onset, and lingering, as well as bitter off-flavor and blocking interactions were deduced from the taste receptor activation curves and then compared. To this end, a flow cell containing a receptor cell array bearing the sweet and six bitter taste receptors was transiently exposed to pure and mixed sweetener samples.

CFAP43 modulates ciliary beating in mouse and Xenopus.

Malfunctions of motile cilia cause a variety of developmental defects and diseases in humans and animal model organisms. Defects include impaired mucociliary clearance of the airways, sperm immotility, hydrocephalus and organ laterality. Here, we characterize the evolutionary conserved Cfap43 gene by loss-of-function experiments in the mouse and the frog Xenopus laevis.

Identification of FOXJ1 effectors during ciliogenesis in the foetal respiratory epithelium and embryonic left-right organiser of the mouse.

Formation of motile cilia in vertebrate embryos is essential for proper development and tissue function. Key regulators of motile ciliogenesis are the transcription factors FOXJ1 and NOTO, which are conserved throughout vertebrates. Downstream target genes of FOXJ1 have been identified in a variety of species, organs and cultured cell lines; in murine embryonic and foetal tissues, however, FOXJ1 and NOTO effectors have not been comprehensively analysed and our knowledge of the downstream genetic programme driving motile ciliogenesis in the mammalian lung and ventral node is fragmentary.

Challenges and Opportunities in the Development of Aptamers for TNFα.

RNA aptamers for tumor necrosis factor-alpha (TNFα), for which functionality was demonstrated in L929 cells, show only little affinity for the protein in vitro. Detailed investigation of the aptamer-protein interaction by surface plasmon resonance and quartz crystal microbalance analysis revealed that affinity is not the only crucial parameter for efficacy and functionality of those aptamers. Instead, the sensitive equilibrium of the monomeric and homotrimeric form of soluble TNFα decides on aptamer binding.

Fabrication of Homogeneous High-Density Antibody Microarrays for Cytokine Detection.

Cytokine proteins are known as biomarker molecules, characteristic of a disease or specific body condition. Monitoring of the cytokine pattern in body fluids can contribute to the diagnosis of diseases. Here we report on the development of an array comprised of different anti-cytokine antibodies on an activated solid support coupled with a fluorescence readout mechanism.
