Risk of Heart Failure Hospitalization for GLP-1 Receptor Agonists Versus DPP-4 Inhibitors or SGLT-2 Inhibitors in Patients With Type 2 Diabetes: A Target Trial Emulation
Xu Y, Huang T, Zhang Y, +4 · Circulation
In a Stockholm 2010–2021 target-trial emulation of 63,083 adults with type 2 diabetes, GLP-1 receptor agonists reduced 3-year heart-failure hospitalization versus DPP-4 inhibitors (HR 0.77; 95% CI 0.66–0.91) but were not different from SGLT-2 inhibitors (HR 1.02; 95% CI 0.85–1.18) — the cleanest comparative-effectiveness signal to date that the GLP-1RA cardioprotective effect is real against DPP-4i but does not match SGLT-2i for the heart-failure endpoint.

GIPR:GCGR co-agonism restores normal weight in obese rodents
Perez-Tilve D, Zhang F, Zhang Y, +6 · Molecular Metabolism
BWB3054, a dual GIPR:GCGR co-agonist designed to attenuate GLP-1R signalling >100-fold, normalised body weight in diet-induced obese mice and rats and matched retatrutide's weight effect — including in GLP-1R-knockout mice — suggesting the GIP and glucagon arms of the triple-agonist can deliver the bulk of the obesity effect without GLP-1R-driven gastrointestinal liability.

Anti-inflammatory and anabolic effects of liraglutide on 3D inflammatory osteoarthritic spheroid and scaffold models of human chondrocytes
Ciftci E, Eberlein SC, Grad S, +3 · Osteoarthritis and Cartilage
In 3D human-chondrocyte spheroid and scaffold cultures stimulated with IL-1β, liraglutide reduced IL-8 release roughly four-fold (877.8 vs 3127.0 ng), elevated ACAN and PRG4 anabolic markers, and preserved extracellular-matrix composition under cyclic mechanical loading — the first systematic in-vitro mechanistic case for a direct GLP-1RA effect on osteoarthritic cartilage independent of weight loss.

Cav3.1 is a neuronal leucine sensor that mediates satiety and weight loss in response to dietary protein
Tsang AH, Heeley N, Alcaino C, +3 · Cell Metabolism
Cambridge Institute of Metabolic Science group identifies Cav3.1 — a T-type voltage-gated calcium channel — as the hypothalamic POMC-neuron leucine sensor that mediates protein-induced satiety, and shows pharmacological Cav3.1 activation in the mediobasal hypothalamus drives weight loss in obese mice and potentiates liraglutide's anorectic response.

The ELAD Phase 2b in 204 non-diabetic adults with mild-to-moderate Alzheimer's disease missed its primary endpoint of cerebral glucose metabolic rate (p=0.14) — but secondary endpoints reported nearly 50% reduction in brain atrophy and 18% slower ADAS-Exec decline, the secondary-positive signal that handed the question to the larger semaglutide EVOKE Phase 3.

Across 1,593,554 patients in a Neurology-published meta-analysis (682,456 semaglutide users vs 911,098 non-GLP-1RA users), semaglutide use was associated with a 2.5-fold increased risk of nonarteritic anterior ischemic optic neuropathy (RR 2.52; 95% CrI 1.56–4.72), with the strongest signal in patients with diabetes (RR 2.41; 95% CrI 1.57–4.10) — the strongest meta-analytic confirmation to date that the NAION safety signal is real.
