The Claim

Autoantibodies targeting the thyroid-stimulating hormone receptor (TSHR) are associated with Graves' disease, with stimulating autoantibodies causing sustained TSHR activation leading to hyperthyroidism and blocking autoantibodies inhibiting TSHR activation leading to hypothyroidism, and both types can be detected simultaneously or at different times in the same patient.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In Graves' disease, antibodies that bind to the thyroid-stimulating hormone receptor either continuously activate it, resulting in excessive thyroid hormone production and hyperthyroidism, or block its activation, resulting in reduced thyroid hormone production and hypothyroidism. Both types of antibodies can be present in the same individual at the same time or at different times.

See the scientific wording

Autoantibodies targeting the thyroid-stimulating hormone receptor (TSHR) are associated with Graves' disease, where stimulating autoantibodies mimic TSH to cause hyperthyroidism, while blocking autoantibodies inhibit TSHR activation and may lead to hypothyroidism, with both types detectable in the same patient at different times or simultaneously.

Why this might work

Some antibodies attach to the thyroid hormone receptor in a way that locks it into an always-on position, forcing the thyroid to make too much hormone. Other antibodies attach to the same receptor in a different spot, blocking the signal that tells the thyroid to make hormone, causing it to make too little. Both types of antibodies can be present at the same time in the same person, competing for the receptor and shifting thyroid function between overactive and underactive states.

  1. Study: Autoantibodies to the TSH Receptor—from discovery to understanding the mechanisms of action and to new therapeutics

    In Graves' disease, some antibodies make the thyroid overproduce hormones (causing hyperthyroidism), while others block the thyroid from making hormones (causing hypothyroidism). This study shows both types can exist in the same person, sometimes at the same time.
