Immunosuppression is a reduction of the activation or efficacy of the immune system. Some portions of the immune system itself have immunosuppressive effects on other parts of the immune system, and immunosuppression may occur as an adverse reaction to treatment of other conditions.
Severe thyroid atrophy presents often with denser fibrotic bands of collagen that remains within the confines of the thyroid capsule. [60] Generally, pathological findings of the thyroid are related to the amount of existing thyroid function - the more infiltration and fibrosis, the less likely a patient will have normal thyroid function.

For medications, the term immunosuppression generally refers to both beneficial and potential adverse effects of decreasing the function of the immune system, while the term immunodeficiency generally refers solely to the adverse effect of increased risk for infection. Many specific diseases directly or indirectly cause immunosuppression.
Treatments for autoimmune disease have traditionally been immunosuppressive, anti-inflammatory, or palliative. [12] Managing inflammation is critical in autoimmune diseases. [ 36 ] Non-immunological therapies, such as hormone replacement in Hashimoto's thyroiditis or Type 1 diabetes mellitus treat outcomes of the autoaggressive response, thus ...
Severe hypothyroidism can be dangerous, which is why it’s so important to have a conversation with your healthcare provider if you’re experiencing noticeable symptoms, says Alexander.
The immunosuppressive drugs also interact with other medicines and affect their metabolism and action. Actual or suspected immunosuppressive agents can be evaluated in terms of their effects on lymphocyte subpopulations in tissues using immunohistochemistry .
After undergoing solid organ transplant (liver, kidney, pancreas, etc.), patients are prescribed immunosuppressive agents, such as tacrolimus or cyclosporine. These medications target CD4 immune cells, suppressing their function. IRIS in these patients is thought to be due to the pro-inflammatory response after withdrawal of immunosuppressants.
Glucocorticoids cause immunosuppression, and the therapeutic component of this effect is mainly the decreases in the function and numbers of lymphocytes, including both B cells and T cells. The major mechanism for this immunosuppression is through inhibition of nuclear factor kappa-light-chain-enhancer of activated B cells . NF-κB is a ...
