Function
NFAT5 (Nuclear Factor of Activated T Cells 5), also known as TonEBP (Tonicity-Responsive Enhancer Binding Protein), is a transcription factor that plays crucial roles in cellular stress responses. Unlike other NFAT family members, NFAT5 is activated by osmotic stress rather than calcium signaling [1]. [@cellular2018]
Key functions include: [@therapeutic2017]
Osmoprotection: Regulates expression of osmolyte transporters and synthesis enzymes
Immune response: Controls cytokine expression in immune cells
Neuroprotection: Mediates cellular responses to metabolic and oxidative stress in [neurons](/entities/neurons)
Inflammation: Regulates expression of pro-inflammatory mediators in [microglia](/cell-types/microglia-neuroinflammation) and [astrocytes](/entities/astrocytes) [2]
In the central nervous system, NFAT5 is expressed in neurons, astrocytes, and microglia, where it contributes to: [@biomarkers2016]
Hippocampal synaptic plasticity
Astrocyte responses to injury
Microglial activation states
Disease Associations
Multiple Sclerosis
NFAT5 regulates expression of inflammatory genes in T cells and microglia [3]
Genetic variants in NFAT5 have been associated with MS susceptibility [4]
NFAT5 activation in glial cells contributes to demyelination and neuroinflammation [5]
Alzheimer's Disease
NFAT5 is activated in AD brain tissue in response to amyloid pathology [6]
Regulates inflammatory responses in microglia surrounding amyloid plaques
May influence [tau](/proteins/tau) phosphorylation through stress kinase pathways [7]
Retinal Degeneration
NFAT5 plays important roles in retinal pigment epithelium function [8]
Expression
Brain: Expressed in neurons (especially hippocampus), astrocytes, and microglia
Regional Distribution: High expression in [hippocampus](/brain-regions/hippocampus), [cortex](/brain-regions/cortex), and hypothalamus
Upregulation: Strongly induced by osmotic stress, inflammation, and neuronal injury
