Although the presence of this TSH-R variant could provide the antigenic link between the thyroid and the orbit in Graves' disease and thyroid-associated ophthalmopathy (TAO), the etiopathophysiological significance of this finding remains to be elucidated.
For geosynchronous orbit satellites (IGSOs) and medium earth-orbit satellites (MEOs), a slight fluctuation can also be observed that is similar to that of GPS satellites, except for the satellite-included code bias.
Herein, we examined the IGKV/IGLV gene usage and mutations in 34 C. psittaci-negative OAMALTL originating from the orbit (15), conjunctivae (14), and lacrimal gland (5).

The thyrotropin receptor (TSHR) represents the central autoantigen involved in GD and has been proposed as the thyroid antigen shared with the orbit that could explain the infiltration of immune cells into tissues surrounding the eye.
GD is a systemic autoimmune thyroid disorder characterized by the infiltration of immune effector cells and thyroid-antigen-specific T cells into the thyroid and thyroid stimulating hormone receptor (TSHR) expressing tissues, i.e. orbit, skin, with the production of autoantibodies to well-defined thyroidal antigens.
As the TSH receptor (TSHR) is the primary target for autoimmunity against the thyroid in Graves' disease, much effort has gone into investigating the role of TSHR messenger ribonucleic acid (mRNA) transcripts in extrathyroidal tissue, particularly in the orbit.
These studies suggest that the expression of this receptor in the orbit in vivo may be stimulated by TSH or other TSHr ligands, and that this stimulation may be important in the development of GO.
Impacts of real-time satellite orbit and clock products on GPS point and relative positioning are then investigated using the P3 and GAMIT software packages, respectively.
The orbit infiltrating CD34+ fibrocytes add on to the process by expressing high levels of autoantigens and inflammatory cytokines, while also differentiating into myofibroblasts or adipocytes.
They putatively infiltrate the orbit in thyroid-associated ophthalmopathy where they appear to transition into CD34(+) orbital fibroblasts (OFs) that interact with residential CD34(-) fibroblasts.
