Allergic rhinitis
Comprehensive research background on the pathophysiology, diagnosis and management of allergic rhinitis.
Featured Indication · Pollen Allergy
How the nasal spray platform pulls pollen allergy from hypersensitivity back toward immune tolerance
Pollen allergy is highlighted as a standalone indication because it most clearly expresses the platform logic: precise downregulation of overactive allergic signaling, nasal barrier repair, local immune-threshold reset, and reduced amplification of the neuroimmune reflex loop.
Th2 Elevated
The most characteristic immune-imbalance starting point in pollen allergy
Treg Deficiency
Reduced weighting of the local immune-tolerance braking system
NALT Threshold Drift
Nasal-associated lymphoid tissue misreads mild exposure as high risk
Neural Hypersensitivity + Barrier Fragility
Creates an amplification state where minor stimuli cause major symptoms
Five Core Mechanistic Pathways
Complete mechanism map for pollen allergy
These five pathways cover the full chain from upstream immune imbalance to downstream symptom amplification, which is why pollen allergy is isolated as the featured card on the main page.
01
Immune Rebalancing
Pollen Allergy
Precisely downregulating the overactive Th2 allergic pathway
The core problem is not pollen itself, but the body's tendency to classify otherwise tolerable environmental particles as danger signals requiring intense response. The platform first targets the excessively active Th2 bias and reduces the allergic amplification tendency associated with IL-4 / IL-5 / IL-13 signaling.

02
Tolerance Rebuilding
Pollen Allergy
Increasing Treg regulatory weight to pull immunity back into a tolerant range
Simply lowering inflammation is not enough, because the local immune system may still remain in a hyper-alert state. The platform therefore raises Treg-linked tolerance signaling so the nasal mucosa can rebuild a more stable immune brake against environmental antigens.

03
Threshold Reset
Pollen Allergy
Resetting NALT so mild exposure no longer triggers maximal reaction
Many flare events occur not because exposure is truly massive, but because nasal-associated lymphoid tissue has already begun interpreting very small stimuli as high-priority threats. The platform treats NALT as a threshold-rebuilding node so that short outdoor exposure or minor pollen fluctuations are less likely to trigger the full sneeze-itch-runny cascade.

04
Neural Desensitization
Pollen Allergy
Reducing sensory hypersensitization to interrupt the neuroimmune reflex chain
Severe symptoms do not arise only from stronger inflammation, but from sensory nerves amplifying the signal. By reducing local neural hypersensitization, the platform aims to lessen itch, repeated sneezing, burning, and irritation so that the 'minor stimulus to major symptom' reflex chain becomes less easily triggered.
Higher sensory thresholdNeuroimmune de-noisingFewer sneezesLess itch
05
Barrier Repair
Pollen Allergy
Promoting tight-junction expression to reduce repeat allergen penetration
When the nasal barrier remains chronically fragile, pollen particles more easily penetrate and retrigger local recognition, reinforcing allergy over and over again. Beyond immune correction, the platform also supports epithelial tight-junction expression and mucosal integrity to reduce opportunities for allergen penetration and interrupt the cycle of repeated hypersensitization.
