Autoantibodies against thyroid proteins are present in several thyroid diseases. Thyroid-stimulating hormone receptor (TSHR) is a G-protein-coupled receptor (GPCR) that binds to thyroid-stimulating hormone (TSH) and stimulates production of thyroxine (T4) and triiodothyronine (T3). When agonized by anti-TSHR autoantibodies, aberrant production of thyroid hormone can lead to Graves' Disease (GD).

Blockade of the PD-L1/PD-1 pathway has proven to be a broadly effective cancer immunotherapy. FDA-approved therapeutic monoclonal antibodies (mAbs) targeting the pathway have high affinity, blocking capacity, and low antibody effector activity. A number of rat antimouse mAbs have been used to model cancer immunotherapy in mouse models.

Blockade of the PD1 pathway is a broadly effective cancer therapy, but additional immune-inhibitory pathways contribute to tumor immune evasion. HERV-H LTR-associating 2 (HHLA2; also known as B7H5 and B7H7) is a member of the B7 family of immunoregulatory ligands that mediates costimulatory effects through its interaction with the CD28 family member transmembrane and immunoglobulin domain containing 2 (TMIGD2). However, HHLA2 has also been known to have inhibitory effects on T cells.

Programmed death ligand 1 (PD-L1)-mediated immunosuppression regulates peripheral tolerance and is often co-opted by tumors to evade immune attack. PD-L1 binds to PD-1 but also binds to B7-1 (CD80) to regulate T-cell function. The binding interaction of PD-L1 with B7-1 and its functional role need further investigation to understand differences between PD-1 and PD-L1 tumor immunotherapy.
