Interplay Between River Formation and Historical Climatic Changes Drove Diversification of the Thamnomanes caesius and T. schistogynus (Passeriformes, Thamnophilidae) Species Complex Across Amazonian and Atlantic Forests

open access: yesZoologica Scripta, Volume 55, Issue 4, Page 555-567, July 2026.
ABSTRACT The Amazon and Atlantic forests harbour immense biodiversity shaped by complex evolutionary history with diverse processes leading to species build‐up. We investigated the Cinereous Antshrike species complex (Thamnomanes caesius and T. schistogynus) to disentangle the relative contributions of riverine barriers and historical climatic ...

Aptamer‐Based Delivery Systems for VEGF and NGF Modulation in Ocular Therapies

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 23, 19 June 2026.
Aptamer‐based delivery systems targeting NGF and VEGF hold significant potential for precise and sustained treatment of complex diseases affecting both the anterior and posterior segments of the eye. This review critically summarizes current strategies for NGF and VEGF delivery as well as VEGF sequestration, providing a clinical perspective on how ...

Simultaneous Electrochemical Detection of NGF and proNGF Under Native Conditions Using Molecularly Imprinted Polymers: Toward Point‐of‐Care Diagnosis of Alzheimer's Disease

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 23, 19 June 2026.
This study relies on the development of a new sensor that can detect two closely related proteins involved in Alzheimer's disease at the same time. Unlike traditional methods, it works in natural conditions and does not require sample pretreatment. The device is highly sensitive and was successfully tested on patient samples, offering promises for ...

Hepatocyte BDNF Acts as a Novel Immune Checkpoint to Restrain TLR4‐Mediated Acute Hepatitis

open access: yesAdvanced Science, Volume 13, Issue 32, 9 June 2026.
This study identifies hepatocyte‐derived BDNF as an endogenous TLR4 antagonist that alleviates acute hepatitis. BDNF is downregulated in hepatocytes via REST‐mediated transcriptional repression during ALI/ALF. Mechanistically, BDNF binds to TLR4 on macrophages to suppress inflammation.

Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Decoding Undesirable Inflammatory Responses of Nucleic Acid‐Delivering Lipid Nanoparticles

open access: yesAdvanced Science, Volume 13, Issue 33, 15 June 2026.
Lipid nanoparticles (LNPs) enable efficient nucleic acid delivery, but their immunogenicity is a double‐edged sword. This review explores LNP‐driven innate and adaptive immunity, covering lipid components, endosomal escape, and nucleic acid sensing.

A lifespan staging model of basal forebrain cholinergic vulnerability

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract The cholinergic neurons of the basal forebrain are among the most vulnerable cell types to age‐ and Alzheimer's disease‐related dysfunction and neurodegeneration. However, the biological bases of basal forebrain cholinergic vulnerability (the why) and the temporal sequence (the how) have yet to be fully resolved.

Reduction in hippocampal cholinergic neurostimulating peptide enhances memory impairment in AppNL‐G‐F KI mice

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Whether cholinergic activity in the septohippocampal network affects cognitive dysfunction via hippocampal cholinergic neurostimulating peptide (HCNP) in Alzheimer's pathogenesis remains unclear. METHODS An Alzheimer's pathogenesis by mutation in amyloid‐beta precursor protein gene (AppNL‐G‐F) knock‐in (KI) and HCNP precursor ...

Epigenetically driven impairment of BDNF–ARC signaling contributes to circadian and cognitive disarray in a mouse model of postoperative delirium

open access: yesAlzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Postoperative delirium (POD) is common in older surgical patients and is clinically associated with an increased risk of long‐term cognitive decline and dementia; disrupted BDNF signaling and circadian dysregulation are implicated, but their coordinated mechanisms remain unclear.
