Problems solved by technology

In recent years, the research on GD animal models has made important progress, among which the TSHR-adenovirus model is widely respected in terms of success rate and replicability; GO animal models are also being explored and tried continuously, including TSHR-plasmid-assisted Protocols of electroporation and TSHR-adenovirus multiple injections, but insufficient in reproducing hyperthyroid state and ocular disease state, respectively

experiment example 1

[0056] Experimental case 1. Preparation of animal model of thyroid-related eye disease

[0057] Experimental equipment: Ad-TSHR (purchased from Shenzhen Baienwei Biotechnology Co., Ltd.), PBS, female 6-8 weeks old inbred BALB / C mice (purchased from Beijing Weitong Lihua Laboratory Animal Technology Co., Ltd.)

[0058] Preparation:

[0059] 1. The adenovirus (Ad-TSHR) stock solution expressing human thyroid stimulating hormone receptor is diluted with PBS according to the volume ratio of 1:50;

[0060] 2. 6-week-old healthy female BALB / C mice were randomly divided into two groups, the control group (8 mice) and the modeling group (22 mice).

[0061] 3. Mice in the control group were injected with adenovirus expressing green fluorescent protein (Ad-EGFP); mice in the model group were injected with adenovirus with extracellular fragment of TSH receptor (Ad-TSHR). The dose of each injection was 10^8 pfu, and 25ul was injected into the left and right gluteus maximus muscles respe...

[0075] Experimental case 2. Evaluation of therapeutic effect of rapamycin on animal model of thyroid-related ophthalmopathy

[0076] Experimental equipment: Ad-TSHR (purchased from Shenzhen Baienwei Biotechnology Co., Ltd.), PBS, female 6-8 weeks old inbred BALB / C mice (purchased from Beijing Weitong Lihua Laboratory Animal Technology Co., Ltd.), Rapamycin (purchased from Shanghai Dibo Biotechnology Co., Ltd.)

[0077] experimental method:

[0078]1. Add rapamycin powder to mouse feed in the form of enteric-coated microparticles (14ppm);

[0079] 2. 6-week-old healthy female BALB / C mice were randomly divided into three groups: normal control group, common modeling group, and rapamycin group;

[0080] 3. The normal model group and the rapamycin group were stimulated by gene immunization-induced thyroid-related eye disease animal model, and the normal control group was stimulated by injection of adenovirus expressing green fluorescent protein (Ad-EGFP). The normal control gro...

Abstract

The invention discloses a method for constructing an animal model of thyroid-associated eye disease induced by gene immunity and application of rapamycin drugs. The construction method is as follows: 1) Dilute the stock solution of adenovirus expressing human thyroid-stimulating hormone receptor with PBS at a volume ratio of 1:50 to obtain Ad-TSHR dilution; 2) On the first day of the 0th week, give the experimental The left and right gluteus maximus of the animal were injected with 25uL Ad-TSHR dilution respectively; 3) the operation of step 2) was repeated in the 3rd, 6th, 10th, 14th, 18th, 22nd, 26th, and 30th weeks until the experimental animals were induced to produce Thyroid-associated eye disease, that is, the successful construction of an animal model of thyroid-associated eye disease induced by gene immunity. The invention fills up the gap in the field of thyroid-associated eye disease models, and is also a new exploration of rapamycin for the treatment of thyroid-associated eye diseases.

Description

technical field [0001] The invention belongs to the technical field of biomedicine, and relates to a method for constructing an animal model of thyroid-related eye disease induced by gene immunity and the application of rapamycin drugs. Background technique [0002] Graves' disease (GD), also known as toxic diffuse goiter, is an organ-specific autoimmune disease whose pathogenesis is that the body produces thyroid-stimulating hormone receptor (TSHR) thyrotropin receptor antibody (TRAb). [0003] Thyroid-related ophthalmopathy, also known as Graves' Ophthalmopathy (GO), is a common extrathyroidal complication of Graves' disease, with an incidence of 20%-50% in patients with Graves' disease. As an autoimmune-mediated inflammatory disease, GO occurs when the body breaks the immune tolerance of T cells to self-antigens under the combined action of genetics and the environment, and then antigen-specific T cells develop specificity in the thyroid and orbital tissues. Cross-react...
