GLT-1, CB1-CREB, and TBI Cognitive Dysfunction
2026-08-13
This 2025 mouse study identifies a mechanistic connection between post-traumatic glutamate dysregulation and endocannabinoid signaling: elevated 2-AG activates CB1, suppresses CREB phosphorylation in astrocytes, and reduces GLT-1. Pharmacological CB1 blockade restored GLT-1, reduced neuronal apoptosis, and improved cognitive performance, positioning the astrocyte-neuron glutamate axis as a testable target in traumatic brain injury research.

TMEM16F in Kupffer Cells Protects Against Listeria
2026-08-12
This 2024 study identifies Kupffer cell-expressed TMEM16F as a central determinant of host protection during Listeria monocytogenes infection. Its experiments connect calcium-activated lipid scrambling and plasma-membrane repair with control of liver inflammation, cell death, and metabolic disruption, while distinguishing this mechanism from conclusions based solely on lymphocyte function.

Poly-GA, ERK1/2, and Tau in C9orf72 Models
2026-08-11
The reference study identifies an ERK1/2-centered mechanism connecting C9orf72-associated poly-glycine-alanine to tau phosphorylation, tau aggregation, and neuronal cell death in a cellular model. Its pharmacological rescue experiments position MEK1/2–ERK signaling as a testable mediator of poly-GA toxicity, while also emphasizing the limits of extrapolating in vitro findings to human disease.

Psoralen-Induced Cholestasis via ERK1/2
2026-08-10
Chen et al. show that psoralen and isopsoralen, estrogen-like constituents of Psoraleae Fructus, produce cholestatic liver injury in zebrafish larvae through ERK1/2 activation. By combining estrogenic, hepatobiliary, gene-expression, and pharmacologic rescue assays, the study identifies ERK1/2 as a mechanistically testable node in phytoestrogen-induced cholestasis.
