Mechanisms of spinal glial activation in chemotherapy‐induced peripheral neuropathy: Focus on microglia and astrocytes

Ibrain, Volume 12, Issue 1, Page 65-85, Spring 2026.
Chemotherapy‐induced peripheral neuropathy (CIPN) remains a major clinical challenge, with central sensitization considered an important pathological mechanism in its occurrence and persistence. This review focuses on spinal astrocytes and microglia, systematically summarizing the pathological mechanisms of spinal glial cells involved in CIPN caused by

The role of p2x7 receptor in infectious inflammatory diseases and the influence of ectonucleotidases

Biomedical Journal, 2014
The purinergic receptor P2X ligand-gated ion channel 7 (P2X7) is ubiquitously expressed in almost all tissues and organs of the body with the highest distribution in the immune cells of monocyte-macrophage origin.

Expression of Purinergic and Endothelial Activation Markers in Brain Tissue From Fatal Microcephaly Associated With ZIKV

Immunity, Inflammation and Disease, Volume 14, Issue 3, March 2026.
ABSTRACT Background Zika virus (ZIKV) is a flavivirus that has gained global attention due to its association with congenital microcephaly and neuroinflammatory responses. Markers of endothelial activation and purinergic signaling have been identified in the context of ZIKV neuropathogenesis, although the underlying mechanisms remain poorly understood.

The P2X7 Receptor Mediates Toxoplasma gondii Control in Macrophages through Canonical NLRP3 Inflammasome Activation and Reactive Oxygen Species Production

Frontiers in Immunology, 2017
Toxoplasma gondii (T. gondii) is the protozoan parasite that causes toxoplasmosis, a potentially fatal disease to immunocompromised patients, and which affects approximately 30% of the world’s population.

Sex Differences in Metabolite–Immune Circuits of Neuroinflammation

Immunological Reviews, Volume 338, Issue 1, March 2026.
ABSTRACT Sex is a fundamental yet underexplored determinant of human neuroinflammation. Across autoimmune, neurodegenerative, and post‐infectious neurological syndromes, males and females exhibit consistent differences in disease vulnerability, progression, and immune tone.

Deficiency of Tissue Nonspecific Alkaline Phosphatase Dysregulates Microglial Morphology and Function in a Mouse Model of Infantile Hypophosphatasia

Journal of Neurochemistry, Volume 170, Issue 3, March 2026.
Using male and female tissue‐nonspecific alkaline phosphatase (TNAP) knockout (KO) and wild type (WT) mice, we show TNAP loss impairs growth and sensorimotor function and induces marked microglial morphological changes (enlarged soma, retracted processes).

Inflammatory response and parasite regulation in acute toxoplasmosis: the role of P2X7 receptor in controlling virulent atypical genotype strain of Toxoplasma gondii

Frontiers in Immunology
Toxoplasmosis is a globally significant disease that poses a severe threat to immunocompromised individuals, especially in Brazil, where a high prevalence of virulent and atypical strains of Toxoplasma gondii is observed.

Optochemical modulation of corneal cold nerve terminal impulse activity with a photochromic ion channel blocker

British Journal of Pharmacology, Volume 183, Issue 3, Page 545-559, February 2026.
Background and Purpose The functional organization of corneal cold nerve endings, critical structures in maintaining the ocular surface, remains poorly understood. Here, the photoisomerizable small‐molecule diethylamine‐azobenzene‐quaternary ammonium (DENAQ) was used to photomodulate activity of cold‐sensing nerve terminals in control and chronic tear ...

Astrocyte Regulation of Spinal Circuit Function

Journal of Neurochemistry, Volume 170, Issue 2, February 2026.
Spinal cord astrocytes exist as an additional component of the computational framework that governs both sensory perceptions and motor outputs (left). By integrating local synaptic activity together with signals that reflect whole‐body state (e.g., neuromodulators, immune signals, and vascular signals) into defined input states (Sn), astrocytes adapt ...

P2X7 on mouse T cells: one channel, many functions

Frontiers in Immunology, 2015
The P2X7 receptor is an adenosine triphosphate (ATP)-gated cation channel that is expressed by several cells of the immune system. P2X7 is best known for its proinflammatory role in promoting inflammasome formation and release of mature IL-1β by innate ...
