Hot Topics: Rise up against statistical significance, probably.

A recent commentary in Nature has the provocative title “Retire Statistical Significance” (1, with a list of more than 800 signatories) and has been widely interpreted as a call for the entire concept of statistical significance to be abandoned. Closer

Hot Topics: Exciting Times for Ion Channel Pharmacology

Whilst life is always exciting as an ion channel pharmacologist, the last few months have been particularly so, with a large number of publications showing structures of ion channels with regulatory molecules bound to them. In just the last month,

Hot Topics: Ligand biological activity predicted by cleaning positive and negative chemical correlations

New machine learning algorithm for drug discovery that is twice as efficient as the industry standard and identified potential ligands for the M1 receptor, a potential target for the treatment of Alzheimer’s disease. A paper from Lee et al. [1]

Hot Topics: An online resource for GPCR structure determination and analysis

G protein-coupled receptors (GPCRs) transduce physiological and sensory stimuli into appropriate cellular responses and mediate the actions of one-third of drugs. Structures of GPCRs are therefore extremely valuable for understanding basic receptor function and rational drug design. Today, 310 structures

Hot Topics: New Cannabinoid Receptors Structures

Cannabinoid receptors respond to multiple endogenous fatty acid derivatives and are often divided into neuronal-associated CB1 receptors and immune cell-associated CB2 receptors. Both receptors are GPCR, coupled predominantly to Gi, and have cytoprotective properties. The predominant psychotropic agent in Cannabis, THC,

Hot Topics: GPR37/GPR37L1 and the putative pairing with prosaptide/PSAP

Comments by Dr. Nicola J. Smith, National Heart Foundation Future Leader Fellow & Group Leader, Molecular Pharmacology Laboratory, Victor Chang Cardiac Research Institute, Australia As is often the case with orphan GPCRs, assigning the endogenous ligand has been controversial for the

Hot Topics: Somatic APP gene recombination in normal and Alzheimer’s disease neurons

A new facet of the human brain has been reported [1] involving a first example of somatic gene recombination in neurons, representing a normal neural mechanism whose disruption could underlie the most common (sporadic) forms of Alzheimer’s disease. Mosaic and
