    A Missed Alzheimer’s Opportunity? Not So Much

    The Washington Post made quite a splash with this story about Pfizer, Enbrel (etanercept), and Alzheimer’s disease. There’s already been a lot of comment about it yesterday on Twitter and in some other venues, but I thought it might be useful to try to sum things up in an easily accessible place. Here we go: Read More

    The Secret Life of the Insulin Receptor

    You’d think that we would understand the workings of something like the insulin receptor by now, wouldn’t you? I worked in the metabolic disease area for several years, and I can give you the canonical version of its activities as it relates to insulin levels and glucose handling out in the canonical tissues (muscle, adipose).

    Autism Mouse Models for the Microbiome?

    Many readers will have seen the paper that just came out on a possible mouse-model demonstration of a connection between autism and the gut microbiome. It’s certainly generated a lot of headlines, and its very title guaranteed that it would: “Human Gut Microbiota from Autism Spectrum Disorder Promote Behavioral Symptoms in Mice“.… Read More

    VCAM1 As a Player in the Aging Brain

    Possible intervention targets for age-related degeneration are always welcome, particularly when they come bearing experimental evidence, and even more so when they relate to the central nervous system. That’s the case with this new paper, from a multicenter team led out of Stanford. Interestingly, this also ties in with the well-publicized … Read More

    There Is No “Depression Gene”

    I wrote a couple of years ago about the long-running study of mutations in a serotonin transporter gene. Over the years, polymorphism in the gene have been correlated with all sorts of human behavior and psychiatry, in keeping with the importance of serotonin signaling in human cognition. Depression, anxiety, that whole end of human behavior… Read More

    Enough With the Mouse Behavioral Models?

    This piece in STAT is well worth a read. The author, Adam Rosenberg of Rodin Therapeutics, is ready to ditch rodent-centric models for human CNS disease, and I can see where he’s coming from. I’ve often said that when I think back on my Alzheimer’s and schizophrenia drug discovery days (back when I was first… Read More

    Making Some New Compounds, to Fit Some New Receptors

    Here’s some medicinal chemistry combined with synthetic biology for you. Many people are used to thinking in terms of finding small-molecule probes for various cell targets, and those are valuable things. But what if you want to control a certain population of (for example) ion channels, but there aren’t any compounds that will do the… Read More

    No Pain, and No Worries?

    The FAAH (fatty acid amide hydrolase) enzyme system has provided a number of headlines over the years. FAAH itself is involved in the brain’s endocannabinoid system – it clears neurotransmitters like anandamide – and a number of other biologically important hydroxyethylamide and acyltaurines. So the potential for inhibitors of it… Read More

    Bacteria and Depression: Something to Test

    Microbiome, microbiome – you haven’t been able to turn around in this business the last few years without hitting some sort of story about the microbiome. It’s easy to roll your eyes and decide that it’s all hype, but that’s the thing: it really is important. It can’t be dismissed just because we don’t unde… Read More

    The Genomics of Neurons. And Alzheimer’s. And Everything Else.

    The brain is a complicated organ. Let’s start there. It’s complicated at every level that you care to examine, and if you get down to the genomic sequences of individual neurons, it’s worse than ever. The sheer variety of neurons and other cell types is quite extreme, and a lot of work over the years… Read More
