Functional neuroimaging studies have reported task-related brain activation changes in preclinical individuals carrying the Huntington's disease (HD) gene mutation (preHD). Little is known about "task-negative" activity, i.e., patterns of task-related deactivation in preHD, and about the stability of any deactivation changes over the course of the disease. Here, we explored ...

Calmodulin (CaM) is a highly conserved intracellular Ca(2+)-binding protein that exerts important functions in many cellular processes. Prominent examples of CaM-regulated proteins are adenylyl cyclases (ACs), which synthesize cAMP as a central second messenger. The interaction of ACs with CaM represents the link between Ca(2+)-signaling and cAMP-signaling pathways. Thereby, different ...

Neurosteroids are steroids synthesized within the brain with rapid effects on neuronal excitability. Allopregnanolone, allotetrahydrodeoxycorticosterone, and androstanediol are three widely explored prototype endogenous neurosteroids. They have very different targets and functions compared to conventional steroid hormones. Neuronal γ-aminobutyric acid (GABA) type A (GABAA) receptors are one of the prime molecular ...

Antifolate antimalarials, such as pyrimethamine, have experienced a dramatic reduction in therapeutic efficacy as resistance has evolved in multiple malaria species. We present evidence from one such species, Plasmodium vivax, which has experienced sustained selection for pyrimethamine resistance at the dihydrofolate reductase (DHFR) locus since the 1970s. Using a transgenic ...
