Method for constructing uveitis animal model
Technical Field
The invention belongs to the field of disease models, and particularly relates to a method for constructing a uveitis animal model.
Background
Uveitis, also known as uveitis, is a general term for inflammation of iris, ciliary body, and choroid tissues. The disease is a common disease in ophthalmology, can cause some serious complications and sequelae, and is one of the main blinding causes. In order to develop a drug for uveitis, a corresponding experimental animal model is essential.
At present, the animal model of uveitis is constructed by a method of inducing autoimmunity and immune mediation by using a plurality of photorefractive tissues including photoreceptor protein, melanin components and the like. Animals mostly use big mice, guinea pigs and rabbits, and have larger differences with human fundus anatomical structures, physiology and pathology; the anatomical structure, physiology and pathology of the eyeground of the non-human primate are relatively similar, but the non-human primate uveitis model is not reported at present.
HS6101, also known as CBLB612, is a novel derivative of a lead medicament CBLB-601. Research shows that HS6101 can inhibit the apoptosis of normal cells induced by stress, and the research shows that the effect of the HS6101 can be used for protecting healthy tissue cells in radiation and chemotherapy.

Detailed Description
Example 1 construction of a non-human primate model of uveitis
Cynomolgus monkeys were taken and injected subcutaneously with 250 ug/kg of HS6101 at a frequency of 2 times per week for 1-4 weeks.
Example 2 construction of non-human primate model of uveitis
Rhesus monkeys were injected subcutaneously with 1000. mu.g/kg of HS6101 at a frequency of 2 injections per week for 1-4 weeks.
Example 3 construction of non-human primate model of uveitis
Rhesus monkeys were injected subcutaneously with 500. mu.g/kg HS6101 at a frequency of 2 times per week for 1-4 weeks.
The invention is further described below in the form of experimental cases.
Experimental example 1 construction of uveitis cynomolgus monkey model
1. Experimental animals: a cynomolgus monkey.
2. Method of producing a composite material
HS6101 was given subcutaneously 2 times a week for 4 weeks at a dose of 500. mu.g/kg per administration with 4 cynomolgus monkeys.
Slit-lamp biomicroscopy, indirect ophthalmoscopy and intraocular pressure examinations were performed on days 8, 12, 18 and 25, respectively. Fundus fluorescence angiography and OCT (optical coherence tomography) examination on day 18. After the experiment, the eyeball is subjected to pathological examination.
3. Results
Monkeys injected within 1 week all developed ocular and conjunctival congestion (conjunctival congestion and ciliary congestion) with edema and pigmentation, and opaque cornea (fig. 1).
Eye examination on day 8 revealed decreased intraocular pressure, mild corneal haze, conjunctival congestion (1/4 ratio), anterior chamber exudation (2/4 ratio), large limbal pigment deposition (2/4 ratio), mild vitreous haze (1/4 ratio), disc edema (3/4 ratio), and the like.
Eye examination on day 12 revealed increased anterior chamber exudation (3/4 rate), decreased intraocular pressure (3/4 rate), mild corneal opacity (2/4 rate), mild vitreous opacity (3/4 rate), and retinal edema on and around the optic disc (3/4 rate). The degree of conjunctival congestion (1/4 ratio) was reduced compared to the former.
Eye examination on day 18 revealed a reduction in the symptoms of conjunctival congestion, corneal clouding, etc., as compared to the earlier stage. The OCT examination of the intraocular examination proves that the retina around the blood vessel of the fundus is obviously edematous and thickened, the reflection of the blood vessel of the retina is enhanced, and the definition of the boundary of each layer of the structure of the retina is reduced; fundus fluorescence angiography examination does not show retinal vessel changes, but fluorescein appears in the later period of angiography, indicating that the inner eye has fluorescence leakage.
Histopathological examination at day 25 revealed inflammatory foci in the ciliary body, choroid, retinal blood vessels, cornea (limbus), and conjunctival epithelial layer.
And judging that the acute uveitis model is successfully constructed by combining the clinical pathological characteristics and the histopathological changes of the ophthalmic examination.
4. Conclusion
The cynomolgus monkey can successfully induce an acute uveitis disease model by subcutaneous injection of HS 6101.
Experimental example 2 construction of uveitis rhesus monkey model
1. Experimental animals: rhesus monkey.
2. Method of producing a composite material
HS6101 was given subcutaneously 2 times a week for 4 weeks at a dose of 500. mu.g/kg per administration of 4 rhesus monkeys.
3. Results
Animals receiving injections within 1 week developed ocular bulbar conjunctival congestion (conjunctival congestion and ciliary congestion) with nebulous clouding of the cornea (fig. 2).
On day 8, eye examination revealed mixed redness of the conjunctiva of the eyes (3/4 ratio), increased or decreased intraocular pressure (2/4 ratio), corneal haze edema (1/4 ratio), glary flare (2/4 ratio), post-corneal deposits (2/4 ratio), disc edema (1/4 ratio), mild vitreous opacity (2/4 ratio), and varicose dilation of retinal veins (1/4 ratio).
On day 12, except for increased disc and peripheral retinal edema (3/4 rate), the severity of ocular pathology generally decreased;
OCT examination at day 18 confirmed that the retinal thickness increased and the structures of the retinal nerve fiber layer, ganglion cell layer, retinal pigment epithelium layer, and choroid were sharply demarcated (FIG. 3). Fundus fluorescence angiography examination showed no retinal vascular changes, but in the late phase of angiography fluorescein appeared in part of the eye indicating a fluorescence leak in the inner eye (fig. 4).
On day 25, histopathological examination revealed inflammatory foci in the ciliary body, choroid, retinal blood vessels, cornea (limbus), and conjunctival epithelial layer.
And judging that the acute uveitis model is successfully constructed by combining the clinical pathological characteristics and the histopathological changes of the ophthalmic examination.
4. Conclusion
Subcutaneous injection of HS6101 into rhesus monkeys successfully induced an acute uveitis disease model.
In conclusion, HS6101 is used for constructing a primate uveitis disease model, and a clinical prodrug efficacy evaluation tool closer to human is provided for developing new uveitis drugs.
