Synthesis and Characterization of New 1,2,4-Triazolo[1,5-a]pyridines That Extend the Life Span of Caenorhabiditis elegans via Their Anti-Inflammatory/Antioxidant Effects.

Arch. Pharm. (Weinheim) 348 , 650-65, (2015)

In the present study, we describe the synthesis of a new set of 1,2,4-triazolo[1,5-a]pyridines and their fused ring systems. The products were assayed for various types of biological activities like a...

KCNQ channels in nociceptive cold-sensing trigeminal ganglion neurons as therapeutic targets for treating orofacial cold hyperalgesia.

Mol. Pain 11 , 45, (2015)

Hyperexcitability of nociceptive afferent fibers is an underlying mechanism of neuropathic pain and ion channels involved in neuronal excitability are potentially therapeutic targets. KCNQ channels, a...

Transcriptional expression of myelin basic protein in oligodendrocytes depends on functional syntaxin 4: a potential correlation with autocrine signaling.

Mol. Cell. Biol. 35(4) , 675-87, (2015)

Myelination of axons by oligodendrocytes is essential for saltatory nerve conduction. To form myelin membranes, a coordinated synthesis and subsequent polarized transport of myelin components are nece...
