Spatial and Temporal Heterogeneity of Macrophage Efferocytosis in Tumors: Emerging Implications for Immunotherapy Biomarkers and Therapeutic Timing

open access: yesCancer Medicine, Volume 15, Issue 9, September 2026.
ABSTRACT Resistance to immune checkpoint blockade (ICB) remains a major barrier in cancer therapy, reflecting the fact that tumor immunity is governed not only by cell type abundance but also by spatial organization and temporal dynamics within the tumor microenvironment (TME).

Migraine: Epidemiology, Risk Factors, Pathophysiology, and Treatment

open access: yesMedComm, Volume 7, Issue 9, September 2026.
Migraine is a highly prevalent, female‐predominant, and disabling brain disorder shaped by genetic susceptibility, hormonal influences, modifiable attack factors, and comorbidity‐related progression. This review integrates current evidence on migraine epidemiology, phase‐specific neurovascular and neuroglial mechanisms, including CGRP signaling and ...

Connexin therapeutics: blocking connexin hemichannel pores is distinct from blocking pannexin channels or gap junctions

open access: yesNeural Regeneration Research, 2021
Compounds that block the function of connexin and pannexin protein channels have been suggested to be valuable therapeutics for a range of diseases. Some of these compounds are now in clinical trials, but for many of them, the literature is inconclusive ...

PANX2 Suppresses Lung Adenocarcinoma Progression by Inducing Disulfidptosis and Enhancing Antitumor Immunity

open access: yesAdvanced Science, Volume 13, Issue 44, 7 August 2026.
ABSTRACT Lung adenocarcinoma (LUAD) remains a leading cause of cancer mortality with limited therapeutic options. Disulfidptosis, a novel cell death modality driven by disulfide stress, represents a promising target, yet its regulation in LUAD is poorly defined. Here, we identify Pannexin 2 (PANX2) as a tumor suppressor in LUAD.

Stress‐Induced Switch in Small Extracellular Vesicle Secretion: From Constitutive ‘Torn Bag Mechanism’ to Exocytosis

open access: yesJournal of Extracellular Vesicles, Volume 15, Issue 8, August 2026.
Stress‐induced switch. Under stress conditions, small extracellular vesicle release shifts from the constitutive ‘torn bag mechanism’ to exocytosis of multivesicular endosomes. https://BioRender.com/xn1pa1e. ABSTRACT The biogenesis of small extracellular vesicles (sEVs) is only partially understood.

Molecular characterization of pannexins in the lens

open access: yes, 2006
Cell communication in the lens is critical for the life-long homeostasis of this tissue. Abundant gap junctions and cell-cell fusions are reported to be indispensable to the metabolic requirements and optical properties of the highly interconnected ...

An unattended image‐processing pipeline for on‐the‐fly quality assessment and 3D exploration in cryo‐EM

open access: yesActa Crystallographica Section D, Volume 82, Issue 8, Page 915-939, August 2026.
We present a fully automated, unattended cryo‐EM pipeline that serves as an on‐the‐fly diagnostic tool, enabling rapid data‐quality assessment and informed decision‐making to maximize data‐collection efficiency.Single‐particle analysis (SPA) by cryogenic electron microscopy (cryo‐EM) has become a cornerstone of structural biology; yet, the workflow ...

Acute activation of hemichannels by ethanol leads to Ca2+-dependent gliotransmitter release in astrocytes

open access: yesFrontiers in Cell and Developmental Biology
Multiple studies have demonstrated that acute ethanol consumption alters brain function and cognition. Nevertheless, the mechanisms underlying this phenomenon remain poorly understood.

Pannexin2 oligomers localize into endosomal vesicles in mammalian cells while Pannexin1 channels traffic to the plasma membrane

open access: yesFrontiers in Cellular Neuroscience, 2015
Pannexin2 (Panx2) is the largest of three members of the pannexin proteins. Pannexins are topologically related to connexins and innexins, but serve different functional roles than forming gap junctions.
