Progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), sporadic multisystem tauopathy, and some forms of frontotemporal dementia with Parkinsonism linked to chromosome 17 are characterized by neuronal and glial lesions accumulating tau protein containing 4 conserved repeats in microtubule-binding domain (4R tau). Corticospinal tract degeneration is not a common feature of 4R tau...
BACKGROUND: Under physiological conditions, the melanocortin system is a crucial part of the complex network regulating food intake and energy expenditure. In pathological states, like cachexia, these two parameters are deregulated, i.e., food intake is decreased and energy expenditure is increased-a vicious combination leading to catabolism. Agouti-related protein (AgRP), the endogenous antago...
Whole-genome duplication (WGD) was experienced twice by the vertebrate ancestor (2 rounds; 2R), again by the teleost fish ancestor (3R) and most recently in certain teleost lineages (4R). Consequently, vertebrate gene families are often expanded in 3R and 4R genomes. Arguably, many types of "functional divergence" present across 2R gene families will exceed that between 3R/4R paralogs of genes ...
Interleukin-4 (IL-4) and IL-13 exert similar, nonadditive effects on endothelial cells, inducing vascular cell adhesion molecule-1 (VCAM-1) expression and subsequent transmigration of eosinophils. The receptor for IL-4 and IL-13 was described as a shared heteromultimeric complex in which the common gamma-chain (gamma c) subunit was essential for activity. Endothelial cell bound both cytokines w...
INTRODUCTION Rheumatoid arthritis (RA) is now suspected to be driven by pathogenic Th17 cells that secrete interleukin (IL)-17 and can be regulated by IL-4. A single-nucleotide polymorphism (SNP), I50V, in the coding region of the human IL-4 receptor (IL-4R) is associated with rapid development of erosive disease in RA. The present study was undertaken to determine whether this SNP renders the ...
CD4+, Th2-mediated inflammation is an important component of airway hyperresponsiveness (AHR) in allergic airway disease. IL-4 specifically interacts with the Type 1 IL-4 receptor comprised of IL-4R and the common chain, whereas IL-4 and IL-13 mediate their effects through a common receptor complex made up of IL-4R and IL13R 1 (i.e. the Type II IL-4 receptor). In this study, we examined the eff...
In postmenopausal women the mechanisms responsible for hypertension have not been completely elucidated, and there are no gender-specific guidelines for women despite studies showing that blood pressure is not as well controlled to goal in women as in men. In the present study we tested the hypotheses that the sympathetic nervous system and the renal sympathetic nerves contribute to hypertensio...
Introduction. – Chiral 5-hydroxy-g-butyrolactones constitute an important class of natural products and have received considerable attention due to their interesting wide range of biological activities [1]. These compounds have found applications as insect anti-feedants [2], cytotoxic agents [3], and flavor constituents in wine, sherry, and tobacco smoke [4]. They also serve as important precur...
Although the receptor for interleukin-4 (IL-4R) is highly expressed on solid human cancer cells, its significance and internalization function is still unclear. To address these issues, we reconstituted Chinese hamster ovarian (CHO-K1) cells with various components of the IL-4R by transient transfection and performed internalization assays using radiolabeled IL-4. Radiolabeled IL-4 internalized...
The closely related Th2 cytokines, IL-4 and IL-13, share many biological functions that are considered important in the development of allergic airway inflammation and airway hyperresponsiveness (AHR). The overlap of their functions results from the IL-4R alpha-chain forming an important functional signaling component of both the IL-4 and IL-13 receptors. Mutations in the C terminus region of t...
