Treatments for fragile X, the leading single-gene cause of autism & intellectual disability, have been frustratingly hard to come by. Great to see Carlos Portera-Cailliau's team at UCLA identify EPAC2 as a new target. The need is urgent. doi.org/10.1016/j.neuron.202…
Fragile X syndrome is the leading inherited cause of intellectual disability & autism, and we still lack treatments that target its underlying biology. A new study from the Portera-Cailliau lab at @dgsomucla profiled gene activity in 2 key types of cortical neurons in a mouse model & found that many signaling pathways were altered in opposite directions in excitatory versus inhibitory cells. This may explain the brain's excitation/inhibition imbalance. Among the genes changed in both cell types, one stood out: Epac2. Reducing it genetically restored cortical balance, & a drug that blocks EPAC2 improved circuit function & several behaviors in the mice. A promising new therapeutic target for fragile X. cell.com/neuron/fulltext/S08…

Super important work🔥 One of the first studies that actually has the power (n=250+ brains) to ask what changes during 'normal' brain aging (no Alzheimer's)
Surprising: Many discoveries we have made 3y ago on aging in brains of mice seem to happen in humans, too. Such as...👇
1) It's not the neurons that seem to be most affected by age! Instead, glia and microglia (the brain's support system) change the most.
2) Microglia launch ~2-3 main expression programs during normal aging: Up-regulation of known microglia aging genes (TSPO, CD22), antigen presentation genes (HLA), signs of an interferon response (IFI44L), induction of 'disease associated' program (GPNMB, SPP1, etc)
A paper in Nature presents the largest-known map of gene expression in the human prefrontal cortex region of the brain. go.nature.com/4yLUu82

One infusion. One year later. Still working.
CRISPR Therapeutics just published the 1-year follow-up on CTX310 — a single-shot gene-editing drug that permanently dials down a cholesterol-driving gene.
No repeat dosing. No daily pill. Just one infusion, over a year ago.
Here's what happened to their LDL.

Replying to @dgsomucla
@dgsomucla researchers are part of the @IntlBrainLab which built massive, open neuro datasets w/ brain-wide Neuropixels recordings from hundreds of mice making perceptual decisions. A new paper adds novel angle to that dataset: recordings from aged mice. The team recorded >18K neurons across 16 brain regions & found that aging brains (equivalent to ~60 humans yrs) have higher firing rates, somewhat more variable neural responses & less stimulus driven quenching of noise. nature.com/articles/s41467-0…

Exciting work from my @dgsomucla colleague @BhaduriLab. Understanding how the brain develops is turning out to be key to understanding how brain tumors hijack those same programs. The boundaries between neuroscience & cancer biology are dissolving in the most productive way. 🧠
Glioblastoma is one of the most devastating brain tumors we know of, & one reason it is so hard to treat is that it doesn't play by normal rules. A new review from Aparna Bhaduri's lab at @dgsomucla reveals why: GBM tumor cells behave like cells from a developing brain, proliferating & differentiating , but w/o the normal controls. By studying the progenitor cells that build the human cortex, Bhaduri's lab is finding unexpected parallels that could point toward new therapeutic strategies. Understanding the brain to fight brain cancer. This is what neuroscience at the intersection of cancer biology looks like. 🧠 annualreviews.org/content/jo…
Who should be infuriated? You!
Love the visual from Cheryl Murray’s LinkedIn post.
Proposed changes to how federal grants are reviewed will affect TONS of people who aren’t scientists. linkedin.com/posts/cherylmur…

This is what integrated science looks like at @dgsomucla. BEAM, a student-led club, connects undergrads passionate about brain health all the way to the clinician-scientists at the Easton Center for Alzheimer's Research and Care, and out into the community at local senior living homes. From world-class research to caring human connection, it's all one ecosystem. Proud of these students. 🧠 dailybruin.com/2026/06/07/be…

The proposed rule raises significant concerns about the introduction of broad political and ideological considerations into federal funding decisions.

Pharma CEO silence is complicity in the destruction of U.S. science.
Office of Management and Budget Director Russell Vought has poured gas on the foundations of science. Pharma CEOs should demand that President Donald Trump take away the matches.
For more than a year, the Trump administration has been weakening the institutions that made the United States the global leader in biomedical innovation. This week, Vought revealed that the objective is not merely to shrink the federal research enterprise, but to make it subservient to political and ideological objectives.
Vought’s proposed rule would require senior political appointees to review and approve every discretionary federal grant before it is awarded, explicitly barring them from deferring to peer reviewers, and would mandate that all grant programs align with the president’s policy priorities, rather than scientific need or expert consensus. It seeks to introduce ideological tests on applicants and institutions that receive grants, bar most international scientific collaboration, and allow political appointees to cancel grants at any time without providing an explanation. The proposal also would allow agencies to make grants that haven’t been publicly announced, opening the process to corruption and favoritism.
If implemented, the proposal would represent the most serious assault on U.S. science since World War II. Even those who agree with the Trump administration’s views on social and political issues should be alarmed. Future administrations with very different views may not abandon the temptation to wield control over scientific funding to advance ideological agendas.

Scientists have concentrated on funding issues, for obvious reasons. But the long-term game of this government is to take away independence from scientists and fully take over decision making. Untrained politicians will be making these decisions for non scientific reasons....
The Trump administration has downsized US science by historic margins — but it's not just via grant or workforce cuts.
Our new @nature analysis reveals the government has cut more than 100 scientific advisory panels across all major science agencies.
Was glad to hear NPR covering how science is not “back to normal.” Damage that has already happened will take decades to repair. In some cases repair isn’t possible. NIH may have a “normal” budget - but it’s not behaving in a predictable/ reliable way. npr.org/2026/05/11/nx-s1-580…

A reminder that the science behind Ozempic traces back to research on the saliva of the venomous Gila monster.
The kind of strange, foundational research that would almost certainly have been cut under today’s standards.
First randomized trial to show Ozempic reduces alcohol consumption in people seeking treatment for alcohol use disorder. Placebo-controlled, double-blind. Participants with BMI >30 kg/m2.

An old favorite for this #FluorescenceFriday. This "rose" is actually a kidney glomerulus (red, podocytes) and an axon reaching towards it (green).
A bout of systemic inflammation in young mice prevented their microglia from condensing plaques months later, leaving neurons vulnerable. #alzheimersdisease @DZNE_de @LMU_Muenchen ow.ly/cNh150YcwzF
