Biological Activity for GTS 21 dihydrochloride

GTS 21 dihydrochloride is a partial agonist of α7 nicotinic acetylcholine receptors (nAChRs); also a weak α4β2 and 5-HT3 antagonist at micromolar concentrations. Exhibits improved sensory inhibition in DBA/2 mice following both acute and chronic administration. Also shown to improve memory in several animal models; facilitates hippocampal long-term potentiation. Also has anti-inflammatory effects independent of α7 nAChRs.

Learning & Memory Poster

Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
