A Spaetzle-like role for nerve growth factor beta in vertebrate immunity to Staphylococcus aureus [PDF]
Many key components of innate immunity to infection are shared between Drosophila and humans. However, the fly Toll ligand Spaetzle is not thought to have a vertebrate equivalent.

Objective. To study the change of expression of TrkA, p75 receptors and their ratio on the human anaplastic astrocytoma, glioblastoma and medulloblastoma cells cultures exposed to nerve growth factor (NGF) and its combination with cisplatin or ...

Steroid Receptors and Vertebrate Evolution [PDF]
Considering that life on earth evolved about 3.7 billion years ago, vertebrates are young, appearing in the fossil record during the Cambrian explosion about 542 to 515 million years ago. Results from sequence analyses of genomes from bacteria, yeast, plants, invertebrates and vertebrates indicate that receptors for adrenal steroids (aldosterone ...

The oncogenic neurotrophin receptor tropomyosin-related kinase variant, TrkAIII
Oncogenes derived from the neurotrophin receptor tropomyosin-related kinase TrkA act as drivers in sub-populations of a wide-range of human cancers. This, combined with a recent report that both adult and childhood cancers driven by novel oncogenic TrkA ...

Accuracy of direct gradient sensing by cell-surface receptors [PDF]
Chemotactic cells of eukaryotic organisms are able to accurately sense shallow chemical concentration gradients using cell-surface receptors. This sensing ability is remarkable as cells must be able to spatially resolve small fractional differences in the numbers of particles randomly arriving at cell-surface receptors by diffusion.

Objective: Brown adipogenesis and thermogenesis in brown and beige adipose tissue (AT) involve vascular remodeling and sympathetic neuronal guidance. Here, we investigated the molecular mechanism coordinating these processes.

Chemical sensing by cell-surface chemoreceptor arrays: the roles of receptor cooperativity and adaptation [PDF]
Most sensory cells use cross-membrane chemoreceptors to detect chemical signals in the environment. The biochemical properties and spatial organization of chemoreceptors play important roles in achieving and maintaining sensitivity and accuracy of chemical sensing.

Antidepressant-like Effects of Neuropeptide SF (NPSF) [PDF]
Neuropeptide SF (NPSF) is a member of RFamide neuropeptides that play diverse roles in central nervous system. Little is know about the effects of NPSF on brain functions. Antidepressant-like effect of NPSF was studied in modified mice FST. NPSF showed the antidepressant-like effects by decreasing the immobility time and increasing the climbing and ...

Expression of NGF, Trka and p75 in human cartilage
Nerve growth factor (NGF) exerts its action through two types of receptor: high-affinity tyrosine kinase A receptor (trkA) and low-affinity p75 receptor.
