In 14 children with epilepsy, 51 with febrile convulsions and 22 with meningitis gamma-aminobutyric acid (GABA) concentrations in lumbar CSF were determined. While the mean for CSF GABA concentrations for all epileptic children was unchanged [144 (range: 73-285) pmol/ml; controls:

We postulate that in mammalian systems neurotransmitter and hormone-like functions of L-tyrosine (LT) and L-DOPA (LD) are mediated via specific membrane-bound and/or nuclear receptors. The structure and function of these receptors may represent an evolutionary continuum of regulatory proteins binding

Tyrosinase, a key copper-containing enzyme involved in melanin biosynthesis, is closely associated with hyperpigmentation disorders, cancer, and neurodegenerative diseases, and as such, it is an essential target in medicine and cosmetics. Known tyrosinase inhibitors possess adverse side effects, and there

Despite advances in diagnosis and the use of different therapeutic regimens in astrocytic high-grade glioma (HGG), the prognosis for patients remains grim. Additional pretherapeutic information is needed to tailor management. To gain additional prognostic information at primary diagnosis, we investigated

IL-2 and IL-15 are common γ-chain family cytokines involved in regulation of T cell differentiation and homeostasis. Despite signaling through the same receptors, IL-2 and IL-15 have non-redundant roles in T cell biology, both physiologically and at the cellular level.

Protein phosphorylation is a reversible post-translational modification controlling many biological processes. Most phosphorylation occurs on serine and threonine, and to a less extend on tyrosine (Tyr). In animals, Tyr phosphorylation is crucial for the regulation of many responses such as

L-Tyrosine (Tyr) and its plant-derived natural products are essential in both plants and humans. In plants, Tyr is generally assumed to be synthesized in the plastids via arogenate dehydrogenase (TyrA(a), also known also ADH), which is strictly inhibited by L-Tyr.
