This video demonstrates a method to generate a mouse model of primed mycobacterial uveitis (PMU) for studying post-infectious uveitis. Upon induction of PMU by intravitreal injection of heat-killed Mycobacterium tuberculosis in a mouse previously immunized with the same immunogen, the progression of chronic inflammation in the eye is analyzed using imaging and histopathological examination
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board.
1. Antigen preparation for subcutaneous injection
2. Subcutaneous injection
3. Antigen stock preparation for intravitreal injection
4. Intravitreal injection procedure on day 0
Figure 1: Mouse intravitreal injection setup. The intravitreal injection is performed on the mouse eye using (A) a micro syringe pump controller connected to the (B) Micropump and (C) an injection syringe. The syringe is loaded and mounted on the (D) Micropump. The mouse head is positioned using (E) ear bars to e...
