Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...

Microglial Deletion of Hrh4 Alleviates Alzheimer's Disease Pathologies by Enhancing Microglial Phagocytosis of Amyloid‐β and Tau

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
Histamine H4 receptor (H4R) antagonist VUF6002 mimics low‐dose X‐ray irradiation in aged Alzheimer's disease (AD) mice, enhancing microglial clearance of amyloid‐beta/hyperphosphorylated tau aggregates and restoring cognition. Microglial H4R deletion activates cAMP/TGF‐β1/Smad3 pathway, enhancing phagocytosis, while TGF‐β receptor 1 deletion abolishes ...

Serum Haptoglobin as a Predictor of Treatment Response in Patients With Chronic Spontaneous Urticaria

open access: yesClinical and Translational Allergy, Volume 16, Issue 1, January 2026.
ABSTRACT Background Chronic spontaneous urticaria (CSU) is a mast cell‐driven disease associated with systemic inflammation and altered immune responses. Haptoglobin (HP), an acute‐phase glycoprotein, exhibits antioxidative and immunomodulatory properties, while zonulin, the precursor of HP‐2, regulates epithelial barrier integrity. We investigated the
