This work was supported by NIH grant DK080351 to PC, and by a generous gift of the Terry and Kristine Gore family.

Experimental Protocol
Once the pituitary immunogen is prepared (see companion article), it is injected subcutaneously into SJL mice (The Jackson Laboratories, stock 000686). A second identical injection is repeated 7 days later. Mice are then used to collect in vivo and post-mortem outcomes.
Step 1. Subcutaneous injection of pituitary immunogen into SJL mice
Mice are first anesthetized by injecting 0.5 ml of 20 mg/ml 2,2,2-Tribr...

Four techniques have been reported to induce hypophysitis in experimental animals. The technique described in this article, that is the injection of pituitary proteins mixed with Freund s adjuvant, is the oldest one, dating back to 19676, and has been improved more recently1. Other techniques are the injection of soluble rubella virus glycoproteins in 19927, the stereotactic injection of an adenovirus directly into the pituitary gland in 20028, and the transplantation of pitu...

induction of experimental autoimmune hypophysitis in sjl mice

Autoimmune hypophysitis can be reproduced experimentally by the injection of pituitary proteins mixed with an adjuvant into susceptible mice1. Mouse models allow us to study how diseases unfold, often providing a good replica of the same processes occurring in humans. For some autoimmune diseases, like type 1A diabetes, there are models (the NOD mouse) that spontaneously develop a disease similar to the human counterpart. For many other autoimmune diseases, however, the model needs to be induced experimentally. A common approach in this regard is to inject the mouse with a dominant antigen derived from the organ being studied. For example, investigators interested in autoimmune thyroiditis inject mice with thyroglobulin2, and those interested in myasthenia gravis inject them with the acetylcholine receptor3. If the autoantigen for a particular autoimmune disease is not known, investigators inject a crude protein extract from the organ targeted by the autoimmune reaction. For autoimmune hypophysitis, the pathogenic autoantigen(s) remain to be identified4, and thus a crude pituitary protein preparation is used. In this video article we demonstrate how to induce experimental autoimmune hypophysitis in SJL mice.
