The Claim
In mice immunized with adenovirus-expressed human TSH receptor residues 1-289, the presence of low-level stimulating TSH receptor antibodies (TSAb) is associated with hyperthyroidism, while the presence of blocking antibodies (TBAb) is associated with normal or suppressed thyroid function, indicating that the relative balance between TSAb and TBAb influences thyroid function.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In mice injected with a viral vector carrying part of the human TSH receptor, those with stimulating antibodies developed hyperthyroidism, while those with blocking antibodies did not, showing that the type of antibody present determines thyroid hormone activity.
See the scientific wording
In mice immunized with adenovirus-expressed human TSH receptor residues 1-289, 8 out of 9 hyperthyroid mice had low-level stimulating TSH receptor antibodies (TSAb), while 7 additional mice had only blocking antibodies (TBAb), suggesting that the balance between stimulating and blocking antibodies influences thyroid function.
When the immune system produces antibodies that activate the thyroid hormone receptor, the thyroid makes too much hormone and the body goes into overdrive. When it produces antibodies that block the receptor instead, the thyroid stays quiet. If both types are present, the blocking antibodies stop the activating ones from working, so the thyroid stays normal.
What the research says
1 studyStudy: MON-429 The TSH Receptor Antibody Reactome Determines Thyroid and Retroorbital Responsiveness
In mice, when the immune system makes antibodies that trick the thyroid into overworking, the mice get hyperthyroid; when it makes antibodies that block the thyroid instead, they stay normal. This shows which kind of antibody matters more than just having any antibody at all.
