WebbThe present study investigated differences in NK1-receptor availability between PTSD patients and healthy controls, using positron emission tomography (PET). Methods: Eleven male refugee patients (age: 41±10) with DSM-IV defined PTSD and nine healthy male control subjects (age: 33±10) were investigated using the PET-tracer [11C]GR205171, … Webb2 sep. 2024 · Introduction Adenosine 2A (A2A) receptors co-localize with dopamine D2 receptors in striatopallidal medium spiny neurons of the indirect pathway. A2A receptor activation in the striatum or pallidum decreases D2 signaling. In contrast, A2A receptor antagonism may help potentiate it. Furthermore, previous PET studies have shown …

WebbAim: The most suitable method for assessment of response to peptide receptor radionuclide therapy (PRRT) of neuroendocrine tumors (NET) is still under debate. In this study we aimed to compare size (RECIST 1.1), density (Choi), Standardized Uptake Value (SUV) and a newly defined ZP combined parameter derived from Somatostatin Receptor … WebbFor HER2 positive cancer cells, silencing abnormal cell signaling is a desired result. Blocking the receptor and targeting aberrant cells for destruction is an established mechanism for disease treatment. On the contrary, “cleaning” the receptor of the treatment drug ligand would allow the cancer to continue growing.
WebbReceptors. Receptors are typically glycoproteins located in cell membranes that specifically recognize and bind to ligands. These are smaller molecules (including drugs) that are capable of 'ligating' themselves to the receptor protein. This binding initiates a conformational change in the receptor protein leading to a series of biochemical ...
