House Dust Mite Extract from D.pteronyssinus (100 μg/mL; nebulization; 10 minutes per administration; 8 total administrations on Days 7, 14, 21, 28, 35, 42, 60, 61) induces significant asthmatic pathology in male BALB/c mice, including elevated airway hyperresponsiveness, inflammatory cell infiltration, immunoglobulin production, cytokine release, bronchial thickening, collagen deposition, and MUC5AC expression, all significantly greater than PBS control levels^[1].
House Dust Mite Extract, from D.pteronyssinus (10-500 μg; i.p.; days 1 and 8; absorbed on 2.0 mg aluminum hydroxide; 500 μg; topical instillation in each eye; days 15, 17, 19) induces allergic conjunctivitis in BALB/c mice, with 10 μg as the optimal intraperitoneal sensitization dose, resulting in the highest total IgE levels, IL-5 production, and proportion of conjunctival CD4⁺ST2⁺ T cells with intracellular IL-5^[2].

Animal Model:	BALB/c (male, 5-week-old)^[1]
Dosage:	100 μg/mL
Administration:	nebulization; 10 minutes per administration; 8 total administrations on Days 7, 14, 21, 28, 35, 42, 60, 61
Result:	Showed significantly higher airway hyperresponsiveness (Penh V) than PBS control at all tested methacholine concentrations (3.1, 6.25, 12.5, 25, 50 mg/mL). Increased total cell, eosinophil, neutrophil, lymphocyte, and macrophage counts in bronchoalveolar lavage fluid compared to PBS control (P < 0.01). Elevated serum IgE, IgG1, and IgG2a levels compared to PBS control (P < 0.05). Increased bronchoalveolar lavage fluid levels of IL-4, IL-5, IL-6, IL-10, IL-13, and IL-17 compared to PBS control (P < 0.05). Increased splenocyte levels of IL-4, IL-5, IL-6, IL-10, IL-13, and IL-17 compared to PBS control (P < 0.05). Caused significantly thicker bronchial mucosa, increased collagen deposition, and higher percentage of PAS-positive cells in lung tissue compared to PBS control (P < 0.01). Increased MUC5AC protein and mRNA expression in lung tissue compared to PBS control (P < 0.01).

Animal Model:	BALB/c (female, 8-week-old, allergic conjunctivitis model via intraperitoneal sensitization followed by topical ocular challenge)^[2]
Dosage:	10 μg (i.p. sensitization); 100 μg (i.p. sensitization); 500 μg (i.p. sensitization); 500 μg (topical ocular challenge)
Administration:	i.p.; days 1 and 8; absorbed on 2.0 mg aluminum hydroxide; topical instillation in each eye; days 15, 17, 19
Result:	Exhibited mean clinical scores of 6 to 7, with symptoms including eye frowning, discharge, and hyperemia (no significant difference between HDM groups). Showed significantly elevated total serum IgE levels: ~800 ng/mL (10 μg i.p. group), ~350 ng/mL (100 μg group), ~250 ng/mL (500 μg group), compared to controls. Displayed significantly elevated HDM-specific IgE (OD 450 nm): ~0.6 (10 μg group), ~0.4 (100 μg group), ~0.3 (500 μg group), compared to controls. Increased cervical lymphocyte proliferation after HDM stimulation: S-phase lymphocyte populations rose from 4.7% to 13.2% (10 μg group), 3.2% to 11.5% (100 μg group), and 3.3% to 12.5% (500 μg group); S-phase CD4+ T-cell populations rose from 5.0% to 11.7% (10 μg group), 1.4% to 3.3% (100 μg group), and 3.4% to 15.5% (500 μg group). Showed significantly elevated IL-4 and IL-5 levels in cervical lymphocyte supernatants after HDM stimulation; IL-5 levels reached ~45 pg/mL in the 10 μg group, significantly higher than other HDM groups. Induced significant conjunctival infiltration of eosinophils (~6-8 cells per slide) and mast cells (~10-14 cells per slide) compared to controls. Had the highest proportion of conjunctival CD4+ST2+ T cells (17.1%) and the highest proportion of these cells with intracellular IL-5 (82.4%) in the 10 μg group, significantly elevated compared to controls.
